Abstract Objective: To assess the prevalence and factors associated with smoking in adolescents with cleft lip and/or palate. Methods: This is a cross-sectional study, developed in a Brazilian public and tertiary hospital between November 2018 and August 2019. Adolescents aged between 12 and 19 years old, previously submitted to cheiloplasty and/or palatoplasty surgeries were included. Data collection was carried out through interviews, guided by questionnaires referring to sociodemographic issues, use and factors associated with smoking. For statistical analysis, Fisher’s Exact Test, Chi-square, Student’s t test and bivariate logistic regression were used, all with a significance level of 5% (p≤0.05). Results: 102 adolescents participated. The prevalence of smoking was 20.6% (n=21). Having cleft lip and palate was associated with smoking (p=0.012). The bivariate analysis showed that not dating (p=0.001; OR=0.19) and owning a home (p=0.032; OR=0.33) were configured as protective factors for the act of being a smoker, while believing that smoking facilitates interaction with young people or with the group of friends (p=0.043; OR=2.95), having friends who use alcoholic beverages (p=0.002; OR=8.40), having friends who use drugs, except cigarettes (p=0.002; OR=5.33), use alcoholic beverages (p<0.001; OR=10.67) and sexual initiation (p<0.001; OR=7.00), were associated with being a smoker. Conclusions: From the knowledge of the profile of adolescents most vulnerable to tobacco use, it is possible to plan and implement educational and preventive actions.

RESUMO Objetivo: Avaliar a prevalência e os fatores associados ao tabagismo em adolescentes com fissura de lábio e/ou palato. Métodos: Estudo de corte transversal, desenvolvido em um hospital público e terciário brasileiro entre novembro de 2018 e agosto de 2019. Foram incluídos adolescentes com idade entre 12 e 19 anos, submetidos previamente às cirurgias de queiloplastia e/ou palatoplastia. A coleta de dados foi realizada por meio de entrevista, guiada por questionários referentes a questões sociodemográficas, uso e fatores associados ao tabagismo. Para a análise estatística, utilizaram-se os testes: exato de Fisher, qui-quadrado, t de Student e regressão logística bivariada, todos com nível de significância de 5% (p ≤ 0,05). Resultados: Participaram 102 adolescentes. A prevalência do tabagismo foi de 20,6% (n=21). Possuir fissura de lábio e palato associou-se ao tabagismo (p=0,012). A análise bivariada mostrou que não namorar (p=0,001; OR=0,19) e possuir habitação própria (p=0,032; OR=0,33) configuraram fatores de proteção para o ato de ser tabagista, enquanto acreditar que fumar facilita a interação com os jovens ou com o grupo de amigos (p=0,043; OR=2,95), ter amigos que usam bebida alcoólica (p=0,002; OR=8,40), ter amigos que usam drogas, exceto o cigarro (p=0,002; OR=5,33), usar bebida alcoólica (p<0,001; OR=10,67) e iniciação sexual (p<0,001; OR=7,00) associaram-se a ser tabagista. Conclusões: Pelo conhecimento do perfil dos adolescentes mais vulneráveis ao uso do tabaco, é possível planejar e programar ações educativas e preventivas.

RESUMO Objetivo: Definir o perfil epidemiológico e os principais determinantes de morbimortalidade dos pacientes cirúrgicos não cardíacos de alto risco no Brasil. Métodos: Estudo prospectivo, observacional e multicêntrico. Todos os pacientes cirúrgicos não cardíacos admitidos nas unidades de terapia intensiva, ou seja, considerados de alto risco, no período de 1 mês, foram avaliados e acompanhados diariamente por, no máximo, 7 dias na unidade de terapia intensiva, para determinação de complicações. As taxas de mortalidade em 28 dias de pós-operatório, na unidade de terapia intensiva e hospitalar foram avaliadas. Resultados: Participaram 29 unidades de terapia intensiva onde foram realizadas cirurgias em 25.500 pacientes, dos quais 904 (3,5%) de alto risco (intervalo de confiança de 95% - IC95% 3,3% - 3,8%), tendo sido incluídos no estudo. Dos pacientes envolvidos, 48,3% eram de unidades de terapia intensiva privadas e 51,7% de públicas. O tempo de internação na unidade de terapia intensiva foi de 2,0 (1,0 - 4,0) dias e hospitalar de 9,5 (5,4 - 18,6) dias. As taxas de complicações foram 29,9% (IC95% 26,4 - 33,7) e mortalidade em 28 dias pós-cirurgia 9,6% (IC95% 7,4 - 12,1). Os fatores independentes de risco para complicações foram Simplified Acute Physiology Score 3 (SAPS 3; razão de chance − RC = 1,02; IC95% 1,01 - 1,03) e Sequential Organ Failure Assessment Score (SOFA) da admissão na unidade de terapia intensiva (RC =1,17; IC95% 1,09 - 1,25), tempo de cirurgia (RC = 1,001; IC95% 1,000 - 1,002) e cirurgias de emergências (RC = 1,93; IC95% 1,10 - 3,38). Em adição, foram associados com mortalidade em 28 dias idade (RC = 1,032; IC95% 1,011 - 1,052) SAPS 3 (RC = 1,041; IC95% 1,107 - 1,279), SOFA (RC = 1,175; IC95% 1,069 - 1,292) e cirurgias emergenciais (RC = 2,509; IC95% 1,040 - 6,051). Conclusão: Pacientes com escores prognósticos mais elevados, idosos, tempo cirúrgico e cirurgias emergenciais estiveram fortemente associados a maior mortalidade em 28 dias e mais complicações durante permanência em unidade de terapia intensiva.

ABSTRACT Objective: To define the epidemiological profile and the main determinants of morbidity and mortality in noncardiac high surgical risk patients in Brazil. Methods: This was a prospective, observational and multicenter study. All noncardiac surgical patients admitted to intensive care units, i.e., those considered high risk, within a 1-month period were evaluated and monitored daily for a maximum of 7 days in the intensive care unit to determine complications. The 28-day postoperative, intensive care unit and hospital mortality rates were evaluated. Results: Twenty-nine intensive care units participated in the study. Surgeries were performed in 25,500 patients, of whom 904 (3.5%) were high-risk (95% confidence interval - 95%CI 3.3% - 3.8%) and were included in the study. Of the participating patients, 48.3% were from private intensive care units, and 51.7% were from public intensive care units. The length of stay in the intensive care unit was 2.0 (1.0 - 4.0) days, and the length of hospital stay was 9.5 (5.4 - 18.6) days. The complication rate was 29.9% (95%CI 26.4 - 33.7), and the 28-day postoperative mortality rate was 9.6% (95%CI 7.4 - 12.1). The independent risk factors for complications were the Simplified Acute Physiology Score 3 (SAPS 3; odds ratio - OR = 1.02; 95%CI 1.01 - 1.03) and Sequential Organ Failure Assessment Score (SOFA) on admission to the intensive care unit (OR = 1.17; 95%CI 1.09 - 1.25), surgical time (OR = 1.001, 95%CI 1.000 - 1.002) and emergency surgeries (OR = 1.93, 95%CI, 1.10 - 3.38). In addition, there were associations with 28-day mortality (OR = 1.032; 95%CI 1.011 - 1.052), SAPS 3 (OR = 1.041; 95%CI 1.107 - 1.279), SOFA (OR = 1.175, 95%CI 1.069 - 1.292) and emergency surgeries (OR = 2.509; 95%CI 1.040 - 6.051). Conclusion: Higher prognostic scores, elderly patients, longer surgical times and emergency surgeries were strongly associated with higher 28-day mortality and more complications during the intensive care unit stay.

Foram avaliados aspectos da língua relacionados à morfologia, frênulo, mobilidade, praxias e força. Foram obtidas as associações entre os aspectos da avaliação clínica, considerando nível de significância de 5%. Resultados Houve associação entre largura e altura; entre extensão do frênulo e as provas de sugar a língua no palato, vibrar, protrair/retrair e tocar comissuras direita e esquerda e lábios superior e inferior e entre a fixação do frênulo no assoalho da boca e as provas de sugar a língua no palato e vibrar. A prova de estalar ápice de língua apresentou associação com estalar o corpo. Estalar a língua (ápice ou corpo) apresentou associação com sugar a língua no palato, vibrar, protrair/retrair, tocar comissuras direita e esquerda e lábios superior e inferior e força. A prova de sugar a língua no palato apresentou associação com vibrar, protrair/retrair, tocar comissuras direita e esquerda e lábios superior e inferior e força de língua e a prova de vibrar a língua, com protrair e retrair e força de língua. Também houve associação entre protrair e retrair e tocar comissuras direita e esquerda e lábios superior e inferior. Conclusão Os aspectos da língua na avaliação clínica apresentaram associações entre si.

ABSTRACT Purpose Investigate the possible association between myofunctional aspects of the tongue clinical evaluation. Methods Observational, cross-sectional study conducted with 80 healthy Brazilian schoolchildren aged 8-12 years: 36 (45%) males and 44 (55%) females. The following aspects of the tongue were assessed: morphology, frenulum, mobility, praxis, and force. Association between the aspects of clinical evaluation was obtained considering a statistical significance level of 5%. Results The following associations were observed: between tongue width and height; between frenulum length and the tasks of sucking the tongue on palate, tongue vibration, tongue protrusion/retraction, and touching right and left commissures and upper and lower lips; between frenulum attachment to the floor of the mouth and the tasks of sucking tongue on palate and tongue vibration. In the snap task, tongue apex snap was associated with tongue body snap. Tongue snap (apex or body) was associated with sucking the tongue on palate, tongue vibration, tongue protrusion/retraction, touching right and left commissures and upper and lower lips, and tongue force. Sucking tongue on palate was associated with tongue vibration, tongue protrusion/retraction, touching right and left commissures and upper and lower lips, and tongue force. Tongue vibration was associated with tongue protrusion/retraction and tongue force. Association was also observed between the tongue protrusion/retraction task and touching right and left commissures and upper and lower lips. Conclusion Association between tongue aspects was verified in the clinical evaluation.

Resumen: En | Texto: En | PDF: En

Abstract Objectives: This study aimed to verify the presence of polyomavirus BK (BKPyV) in the saliva of kidney transplant recipients and to correlate it with blood viremia. Material and Methods: We have conducted a cross-sectional study with a sample involving 126 renal transplant recipients. 126 samples of saliva and 52 samples of blood were collected from these patients. Detection and quantification of BKPyV were performed using a real-time PCR. To compare the presence of BKPyV in blood and saliva, the binomial proportion test was used. To verify associations between salivary shedding BKPyV and post-transplant periods (in months), the Mann-Whitney test was used. Spearman's correlation was used to correlate the viral load in the saliva with blood of kidney transplant recipients. Results: The mean age of the study group was 51.11±12.45 years old, and 69 participants (54.8%) were female, with a mean post-transplantation time of 4.80±6.04 months. BKPyV was quantified in several samples of saliva and blood, with medians of 1,108 cp/mL and 1,255 cp/mL, respectively. Only 16/52 (30.8%) participants presented BKPyV in blood, and 59/126 (46.8%) excreted the virus in saliva (p=0.004). BKPyV shedding was found in patients at a shorter post-transplantation period (3.86±5.25, p=0.100). A weak correlation was observed between viral quantification in saliva and blood (Spearman's correlation coefficient=0.193). Conclusion: The results of this study suggested that, although saliva excretes more BKPyV than blood, there is no reliable correlation between salivary shedding and blood viremia, showing two independent compartments of viral replication.

Resumen: En | Texto: En | PDF: En

Abstract Aspergillus fumigatus is an opportunistic saprobe fungus that accounts for 90% of cases of pulmonary aspergillosis in immunosuppressed patients and is known for its angiotropism. When it reaches the respiratory tract, A. fumigatus interacts with structural components and blood vessels of the lungs, such as elastin. To understand the effect of this structural component, we examined the effect of elastin on the production and development of the biofilm of A. fumigatus. In RPMI containing 10 mg/mL of elastin, a significant increase (absorbance p < 0.0001; dry weight p < 0.0001) in the production of biofilm was observed in comparison to when RPMI was used alone, reaching a maximum growth of 18.8 mg (dry weight) of biofilm in 72 h. In addition, elastin stimulates the production (p = 0.0042) of extracellular matrix (ECM) and decreases (p = 0.005) the hydrophobicity during the development of the biofilm. These results suggest that elastin plays an important role in the growth of A. fumigatus and that it participates in the formation of thick biofilm.

Resumen: En | Texto: En | PDF: En

ABSTRACT The Caatinga biome features an exclusive endemic biodiversity, and is characterized by the presence of xerophytic, deciduous vegetation, high temperatures, and low rainfall. This important park has undergone anthropization, especially through extraction of firewood and timber and growing plants for raising goats. The objectives of this study were to compare the communities of filamentous fungi present in the preserved area and in the anthropized soil of the Catimbau National Park in Buíque, PE, Brazil, and to evaluate the impacts of anthropization on such communities. A total of 12 collections of soil samples were made, six in the preserved area and six in the anthropic area, and the physicochemical properties of the soil samples were analyzed. Fungi were isolated through suspension and serial dilution methods. After growth, the samples were purified and identified based on classical taxonomy, according to specific literature. The diversity, evenness, richness, dominance, frequency, and similarity among the species of filamentous fungi in both areas were assessed based on ecological indexes. A total of 4,488 colony-forming units of filamentous fungi were obtained, which were distributed into 65 species belonging to 15 genera. In the preserved area, higher abundance and richness of species were observed, with predominance of the genera Aspergillus and Penicillium. In both areas, diversity and equitability were high, demonstrating that the species are well distributed in these areas. In the preserved area, the dominant genera were Aspergillus, Gongronella, and Penicillium, whereas Aspergillus was the dominant genus in the anthropic area. Two distinct communities were observed in the areas analyzed. Principal component analysis showed that Penicillium simplicissimum influences the total diversity of both communities. The anthropization that occurred in the Catimbau National Park has changed the composition of the filamentous fungal communities of the site, restricting the number of species and decreasing the abundance of these important microorganisms. This results in ecosystem damage and likely causes relevant major imbalances, with serious consequences, such as possible disappearance of the aforementioned species, as well as of species yet undiscovered by the scientific community.

Resumen: En | Texto: En | PDF: En

Trypanosomatids are parasites that cause disease in humans, animals, and plants. Most are non-pathogenic and some harbor a symbiotic bacterium. Endosymbiosis is part of the evolutionary process of vital cell functions such as respiration and photosynthesis. Angomonas deanei is an example of a symbiont-containing trypanosomatid. In this paper, we sought to investigate how symbionts influence host cells by characterising and comparing the transcriptomes of the symbiont-containing A. deanei (wild type) and the symbiont-free aposymbiotic strains. The comparison revealed that the presence of the symbiont modulates several differentially expressed genes. Empirical analysis of differential gene expression showed that 216 of the 7625 modulated genes were significantly changed. Finally, gene set enrichment analysis revealed that the largest categories of genes that downregulated in the absence of the symbiont were those involved in oxidation-reduction process, ATP hydrolysis coupled proton transport and glycolysis. In contrast, among the upregulated gene categories were those involved in proteolysis, microtubule-based movement, and cellular metabolic process. Our results provide valuable information for dissecting the mechanism of endosymbiosis in A. deanei.

ResumenEl suelo es un sistema biológico complejo, que desempeña un papel fundamental en las plantas y los animales, especialmente en los bosques secos como la Caatinga. Los hongos del suelo, tales como Aspergillus y Penicillium, pueden ser utilizados como bioindicadores para la conservación de la biodiversidad. El objetivo de este estudio fue aislar e identificar las especies de Aspergillus y Penicillium del suelo, en los municipios de Ibimirim y Tupanatinga en el Parque Nacional Catimbau. Cinco colecciones se llevaron a cabo en cada área durante la estación seca de 2012, un total de 25 muestras de suelos por área. Los hongos fueron aislados mediante la suspensión en agua destilada estéril y se sembraron en medio de cultivo Agar Sabouraud más Cloranfenicol y Rosa de Bengala, y también en el medio Agar Dicloran Glicerol. Los aislamientos fueron identificados en el Laboratorio de Colección de Hongos y se confirmaron por secuenciación del espaciador transcrito interno de ADN. Un total de 42 especies fueron identificadas, 22 de ellas pertenecientes al género Aspergillus y 20 al género Penicillium. Los aislamientos de Penicillium mostraron una distribución uniforme en Tupanatinga con índices de uniformidad entre 0.92 y 0.88 en Ibimirim. Entre los aislamientos de Aspergillus el valor encontrado en Tupanatinga (0.85) fue muy similar al encontrado en Ibimirim (0.86). Se observó una gran diversidad y bajo predominio de hongos en las muestras de suelo. Estos resultados contribuyen a la estimación de la diversidad de hongos en ambientes secos, especialmente en la Caatinga, donde la diversidad es decreciente en los suelos que han sufrido alteraciones.

Abstract Soil is a complex biological system that plays a key role for plants and animals, especially in dry forests such as the Caatinga.Fungi from soils, such as Aspergillus and Penicillium, can be used as bioindicators for biodiversity conservation. The aim of this study was to isolate and identify species of Aspergillus and Penicillium in soil, from the municipalities of Tupanatinga and Ibimirim, with dry forests, in the Catimbau National Park. Five collections were performed in each area during the drought season of 2012, totaling 25 soil samples per area. Fungi were isolated by suspending soil samples in sterile distilled water and plating on Sabouraud Agar media plus Chloramphenicol and Rose Bengal, and Glycerol Dicloran Agar. Isolates were identified by morphological taxonomy in the Culture Collection Laboratory and confirmed by sequencing of the Internal Transcribed Spacer of rDNA. A total of 42 species were identified, of which 22 belong to the genus Aspergillus and 20 to Penicillium. Penicillium isolates showed uniform distribution from the collecting area in Tupanatinga, and the evenness indices found were 0.92 and 0.88 in Tupanatinga and Ibimirim, respectively. Among isolates of Aspergillus evenness, the value found in Tupanatinga (0.85) was very close to that found in Ibimirim (0.86). High diversity and low dominance of fungi in soil samples was observed. These results contributed to the estimation of fungal diversity in dry environments of the Caatinga, where diversity is decreasing in soils that have undergone disturbance. Rev. Biol. Trop. 64 (1): 45-53. Epub 2016 March 01.

Resumen: En | Texto: En | PDF: En

The molecular characterization of ten genotypes of the Coffea arabica plants and of seven genotypes of C. canephora having interesting features for coffee breeding programs was carried to select the parents for breeding. A total of 40 SSR and 29 ISSR primers were used. The primers generated a total of 331 (307 polymorphic and 24 monomorphic) bands. Analysis of genetic diversity presented dissimilarity intervals ranging from 0.22 to 0.44 between the Conilon genotypes, from 0.02 to 0.28 between the Arabica genotypes, and from 0.49 to 0.60 between the genotypes of the two species in the joint analysis. Four groups were formed: I = genotypes of C. arabica, II = four progenies of C. canephora, Conilon group, and one non defined C. canephora (Conilon or Robusta), III = one progeny of un-defined C. canephora (Conilon or Robusta) and IV = one progeny of C. canephora of Robusta group. The grouping formed was consistent with the origins of each group. High stabilities of the bifurcations were found by bootstrap analysis. The use of molecular markers of the SSR and ISSR types in the diversity study was efficient in distinguishing genotypes between and within C. arabica and C. canephora.

Resumen: En | Texto: En | PDF: En

The aim of this study was to evaluate peptidase production by Aspergillus terreus in solid-state bioprocess and evaluate its parameters. The best conditions were 5.0 g of wheat bran as substrate, incubation temperature 30°C, inoculum 2.0x105spores/g and 75% saline volume, with production reaching 677 U/mL (5400 U/g culture medium) after 72 h of fermentation. Biochemical characterization of the crude enzymatic extract showed the optimum pH and temperature of 6.5 and 55°C, respectively. The stability at different temperatures and pH values showed that the extract could endure different pH. The evaluation of the ions influence and inhibitors proved that the enzyme required an ion for better activity, which was corroborated with the inhibition of EDTA and PMSF, characterizing serine and/or metallo peptidase. The extract was also tested for specific activities and showed promising results for keratinolytic and collagenolytic activities (0.252 and 0.165 OD/mL, respectively).

Resumen: En | Texto: En | PDF: En

OBJECTIVE: Poor sleep quality is one of the factors that adversely affects patient quality of life after kidney transplantation, and sleep disorders represent a significant cardiovascular risk factor. The objective of this study was to investigate the prevalence of changes in sleep quality and their outcomes in kidney transplant recipients and analyze the variables affecting sleep quality in the first years after renal transplantation. METHODS: Kidney transplant recipients were evaluated at two time points after a successful transplantation: between three and six months (Phase 1) and between 12 and 15 months (Phase 2). The following tools were used for assessment: the Pittsburgh Sleep Quality Index; the quality of life questionnaire Short-Form-36; the Hospital Anxiety and Depression scale; the Karnofsky scale; and assessments of social and demographic data. The prevalence of poor sleep was 36.7% in Phase 1 and 38.3% in Phase 2 of the study. RESULTS: There were no significant differences between patients with and without changes in sleep quality between the two phases. We found no changes in sleep patterns throughout the study. Both the physical and mental health scores worsened from Phase 1 to Phase 2. CONCLUSION: Sleep quality in kidney transplant recipients did not change during the first year after a successful renal transplantation.

Resumen: En | Texto: En | PDF: En

Enzymes obtained by fermentation processes offer a number of advantages and have been widely researched and used throughout the world. This study aimed to partially characterise an inulinase produced from palm and cassava peel. The enzyme was produced via the solid-state fermentation of Aspergillus japonicus URM5633. The optimal temperatures were 50ºC and 55ºC, and the optimal pH values were 5.2 and 3.4 for inulinase fermentatively produced from palm and cassava peel, respectively. The thermostability measurements for inulinase produced in palm showed that the relative activity remained below 100% until 30 minutes of stability for all temperatures, but reached 106.8% at a temperature of 50ºC after 60 minutes. Inulinase from the crude extract of cassava peel was pH stable and only decreased to 55% of the maximal activity over the course of the assay, suggesting that this enzyme can be used in inulinase production and can be utilized in food industries.

Resumen: En | Texto: En | PDF: En

We report two ciprofloxacin and ofloxacin-resistant Neisseria gonorrhoeae strains that were isolated from the urethral discharge of male patients at the sexually transmitted diseases outpatient clinic of the Alfredo da Matta Foundation (Manaus, state of Amazonas, Brazil). The gonococci displayed minimal inhibitory concentrations (> 32.00 µg/mL) and three mutations in the quinolone resistance-determining region (S91F and D95G in GyrA and S87R in ParC). Both isolates were genotyped using N. gonorrhoeae multi-antigen sequence typing and the analysis showed that the ST225 which represented an emerging widespread multi-resistant clone that has also been associated with reduced susceptibility to ceftriaxone. We recommend continued surveillance of this pathogen to assess the efficacy of anti-gonococcal antibiotics in Brazil.

Este trabalho teve como objetivo avaliar culturas de S. cerevisiae diplóides originais, haplóides monocelulares e diplóides recuperados, quanto à capacidade de fermentar em mosto de cana-deaçúcar esterilizado. Vinte e oito culturas foram analisadas, sendo 4 diplóides originais (URM-4420, Fermento Itaiquara FIT, Fermento Lallemand FLA e Fermento Selvagem SEL); 12 haplóides monocelulares provenientes das originais e 12 diplóides recuperados a partir das monocelulares. O percentual de etanol produzido variou de 1,70% a 6,20% e os açúcares redutores infermentescíveis de 0,45 g/100mL a 0,50 g/100mL. Os maiores percentuais de etanol foram produzidos pelas culturas haplóides monocelulares URM-MH3 (4,80%), em 12 horas e SEL-MH1 (6,20%), em 24 horas, correspondendo a valores de produtividade 3,15g.L-1.h-1 e 2,03 g.L-1.h-1 , respectivamente. Os diplóides recuperados não apresentaram teores de etanol detectáveis pelo método utilizado. Os resultados mostram que, dependendo do estado fisiológico das leveduras, seja na forma diplóide ou haplóide monocelular, podem ser produzidos diferentes percentuais de etanol.

This work aimed at the assessment of fermentative capacity of original diploid, monocellular haploid and recuperated diploid cultures of S. cerevisiae in sterilized sugar-cane wort. Twenty eight cultures were analyzed, four being original diploids (URM-4420, Itaiquara Ferment FIT, Lallemand Ferment FLA and Wild Ferment SEL); 12 monocellular haploids from original ones and 12 recuperated diploids from the monocells. The ethanol percentage ranged from 1.7 to 6.2% and the unfermentable reducing sugars from 0.45 to 0.50g/100mL. The highest ethanol percentages were produced by the monocellular cultures URM-MH3 (4.8%) in 12 h and SEL-MH1 (6.2%) in 24 h, corresponding to the productivity values of 3.15 and 2.03 g.L-1.h-1, respectively. The recuperated diploids did not present detectable ethanol content by the method used. The results showed that depending on the physiological state of the yeasts, being in the diploid or monocellular haploid form, different percentages of ethanol could be produced.

Resumen: Pt En | Texto: Pt En | PDF: Pt | PDF: En

Enzimas hidrolíticas secretadas por fungos têm um papel importante na patogenicidade das infecções. Objetivando avaliar a atividade enzimática foram testados 31 isolados de Acremonium mantidos na Coleção de Culturas University Recife Mycology. Fragmentos das culturas foram transferidos para caldo glicosado para reativação e posterior crescimento em meio ágar batata dextrose, para verificar viabilidade, pureza e confirmação taxonômica pela observação das características macroscópicas e microscópicas. Para detecção enzimática foram utilizados substratos de caseína do leite e gelatina para protease, amido para amilase e lecitina de soja para fosfolipase. Das 31 culturas, 26 (83,9%) mantiveram-se viáveis e 24 (92,3%) foram confirmadas taxonomicamente. Das 24 culturas, 12 (50%) apresentaram atividade proteásica, duas (16,7%) em caseína do leite, uma (8,3%) em gelatina e nove (75%) em ambos os substratos; 16 (66,7%) degradaram amido. Nenhuma cultura apresentou atividade fosfolipásica. Conclui-se que espécies de Acremonium são capazes de produzir enzimas envolvidas na patogenicidade das infecções fúngicas.

Hydrolytic enzymes secreted by fungi play an important role in the pathogenesis of infection. With the aim of evaluating the enzymatic activity, 31 isolates of Acremonium stored in the University of Recife Mycology (URM) Culture Collection were tested. Culture fragments were transferred to glycoside broth for reactivation and further growth in potato dextrose agar medium in order to investigate viability and purity and to confirm the taxonomy through observing the macroscopic and microscopic characteristics. To detect enzymes, milk casein and gelatin were used as substrates for proteinase, starch for amylase and soy lecithin for phospholipase. Among the 31 cultures, 26 (83.9%) remained viable and 24 (92.3%) were confirmed taxonomically. Out of these 24 cultures, 12 (50%) presented proteinase activity, of which two (16.7%) were on milk casein, one (8.3%) on gelatin and nine (75%) on both substrates; 16 (66.7%) degraded starch. None of the cultures presented phospholipase activity. It was concluded that Acremonium species are able to produce enzymes that are involved in the pathogenicity of fungal infections.
