ABSTRACT Introduction: Supplementation with probiotics for patients with chronic kidney disease (CKD) may be associated with decreased systemic inflammation. Objective: To assess the impact of oral supplementation with probiotics for patients with CKD on hemodialysis. Method: This double-blind randomized clinical trial included 70 patients on hemodialysis; 32 were given oral supplementation with probiotics and 38 were in the placebo group. Blood samples were collected at the start of the study and patients were given oral supplementation with probiotics or placebo for three months. The probiotic supplement comprised four strains of encapsulated Gram-positive bacteria: Lactobacillus Plantarum A87, Lactobacillus rhamnosus, Bifidobacterium bifidum A218 and Bifidobacterium longum A101. Patients were given one capsule per day for 3 months. Blood samples were taken throughout the study to check for inflammatory biomarkers. Non-traditional biomarkers Syndecan-1, IFN-y, NGAL, and cystatin C were measured using an ELISA kit, along with biochemical parameters CRP, calcium, phosphorus, potassium, PTH, GPT, hematocrit, hemoglobin, glucose, and urea. Results: Patients given supplementation with probiotics had significant decreases in serum levels of syndecan-1 (239 ± 113 to 184 ± 106 ng/mL, p = 0.005); blood glucose levels also decreased significantly (162 ± 112 to 146 ± 74 mg/dL, p = 0.02). Conclusion: Administration of probiotics to patients with advanced CKD was associated with decreases in syndecan-1 and blood glucose levels, indicating potential improvements in metabolism and decreased systemic inflammation.

Resumo Introdução: A suplementação com probióticos na doença renal crônica (DRC) pode estar associada à redução do processo inflamatório sistêmico. Objetivo: Avaliar a suplementação oral com probióticos em pacientes com DRC em hemodiálise. Método: Ensaio clínico, duplo cego, randomizado com 70 pacientes em hemodiálise, sendo 32 do grupo que recebeu o suplemento de probióticos e 38 do grupo placebo. Inicialmente ocorreu a coleta de sangue e suplementação oral com probióticos ou placebo durante três meses. O suplemento probiótico foi composto pela combinação de 4 cepas de bactérias Gram-positivas encapsuladas: Lactobacillus Plantarum A87, Lactobacillus rhamnosus, Bifidobacterium bifidum A218 e Bifidobacterium longum A101, sendo 1 cápsula do suplemento ao dia, durante 3 meses. Após esse período foram feitas novas coletas de sangue para dosagem dos biomarcadores inflamatórios. Foram analisados os biomarcadores não tradicionais: Syndecan-1, IFN-y, NGAL e cistatina C pelo método ELISA, e os seguintes parâmetros bioquímicos: PCR, cálcio, fósforo, potássio, PTH, TGP, hematócrito, hemoglobina, glicose e ureia. Resultados: Os pacientes que receberam suplemento tiveram diminuição significativa dos níveis séricos de syndecan-1 (de 239 ± 113 para 184 ± 106 ng/mL, p = 0,005). Outro parâmetro que diminuiu significativamente nos pacientes que receberam suplemento foi a glicemia (de 162 ± 112 para 146 ± 74 mg/dL, p = 0,02). Conclusão: O uso de probióticos na DRC avançada esteve associado à redução dos níveis de syndecan-1 e glicemia, sinalizando possível melhora no metabolismo e redução do processo inflamatório sistêmico.

Resumen: En | Texto: En | PDF: En

Abstract Several phytogeographic regions (Cerrado, Pantanal, Atlantic Forest, Gran Chaco, and Chiquitano Dry Forests) converge in the state of Mato Grosso do Sul, Brazil, and influence regional biodiversity. Despite a list of birds in the state of Mato Grosso do Sul being published by Nunes et al. (2017), it is necessary to update and critically review avifauna records. In this study, we gathered the results of several records obtained from species lists and online data platforms of the 336 sites in this state over the last decades and grouped them into Main (Primary and Secondary) and Tertiary Lists. The avifauna of Mato Grosso do Sul is composed of 678 species, of which 643 (95%) have records proving their occurrence (Primary List), whereas 34 still lack documentation (Secondary List). The number of related species for Mato Grosso do Sul represents 34% of the Brazilian avifauna. Some species stand out for their unique occurrence in Mato Grosso do Sul, such as Melanerpes cactorum, Celeus lugubris, Phaethornis subochraceus, and Cantorchilus guarayanus, reflecting the influence of different phytogeographic regions of the Chaco and Chiquitano Dry Forests. Migrants represent 20% of the bird community occurring in the state, of which 93 species correspond to migrants from various regions of South America (south and west) and 40 to boreal migrants. Thirty-three species perform nomadic movements across the Pantanal Plain and other regions of the state. Thirty-one species are included in some conservation-threatened categories of global and/or national endangered species lists. Other 30 species are included in the near-threatened category at the global level and 23 at the national level. In addition, species typical of dry forests (in Serra da Bodoquena and Maciço do Urucum) and those from the Atlantic Forest in the south of the state deserve attention due to their restricted distribution and the high anthropogenic pressure on their habitat.

Abstract Background The analysis of the atherogenic potential of the lipid profile for biomarkers, such as the TG/HDL-c ratio, predicts cardiovascular risk better than isolated lipids. Objective To identify the TG/HDL-c cutoff points for multiple risks (hypertension, Diabetes Mellitus, obesity) and to evaluate the association between sociodemographic, clinical, laboratory, anthropometric, and life habit variables and the TG/HDL-c ratio in hypertensive and/or diabetic individuals in the context of Primary Health Care. Methods This was a cross-sectional study with 833 hypertensive and/or diabetic patients, conducted between August 2017 and April 2018. The cutoff point of the TG/HDL-c were obtained by the ROC curve. Cardiovascular risk was discriminated by TG/HDL-c, categorized by the cutoff and evaluated in relation to multiple risks. The magnitude of the association between TG/HDL-c and independent variables was estimated by logistic regression. The significance level of p<0.05 was adopted for all tests. Results The cutoff values of TG/HDL-c (3.26 for men and 2.72 for women) were more sensitive and less specific than those in the literature. Women (OR=1.90 and 95% CI 1.13-3.20) and men (OR=4.58 and 95% CI 1.78-11.76) with multiple risks, and white men, alcohol users, with a history of stroke, had a higher chance of altered GT/HDL-c. Increases in glycosylated hemoglobin, glycemia, and phosphorus in women, and cholesterol, glycemia, and microalbuminuria in men increased the chances of altered TG/HDL-c. Being a former smoker and black reduced the chance of altered TG/HDL-c in women. Conclusions TG/HDL-c proved to be a good indicator for habitual use in Primary Care.

RESUMO. A co-ocorrência de distúrbios comportamentais e comprometimento cognitivo pós-acidente vascular cerebral (AVC) é amplamente descrita na literatura. No entanto, os estudos geralmente não incluem a cognição social entre os domínios cognitivos avaliados. Objetivo: Investigar a potencial associação entre o reconhecimento da emoção facial, uma medida da cognição social, e os sintomas comportamentais e cognitivos na fase subaguda do AVC isquêmico. Métodos: Pacientes internados em uma Unidade de AVC com AVC isquêmico foram acompanhados até 60 dias, quando foram avaliados com os seguintes instrumentos: Mini-Exame do Estado Mental (MEEM); Bateria de Avaliação Frontal (FAB); Teste de Memória Visual da Bateria Cognitiva Breve (VMT); Fluência Verbal Fonêmica (Teste F-A-S); Span de dígitos; Teste de Reconhecimento de Emoção Facial (FERT) e Escala Hospitalar de Ansiedade e Depressão (HADS). Um grupo controle constituído por 21 indivíduos saudáveis também foi submetido à mesma avaliação. Resultados: Dezoito pacientes com AVC isquêmico foram incluídos no presente estudo, apresentando idade, sexo e anos de escolaridade semelhantes aos do grupo controle. Os sintomas de depressão e déficits de memória episódica foram significativamente mais frequentes em pacientes com AVC. O reconhecimento da expressão de tristeza correlacionou-se positivamente com os níveis de ansiedade e depressão, ao passo que o reconhecimento da expressão de medo correlacionou-se negativamente com depressão no grupo de AVC. Conclusões: Após um AVC isquêmico, pacientes podem apresentar alterações de cognição social, especificamente de reconhecimento da emoção facial, em associação com sintomas comportamentais.

ABSTRACT. The co-occurrence of post-stroke behavioral disorders and cognitive impairment has been extensively investigated. However, studies usually do not include social cognition among the assessed cognitive domains. Objective: To investigate the potential association between facial emotion recognition, a measure of social cognition, and behavioral and cognitive symptoms in the subacute phase of ischemic stroke. Methods: Patients admitted to a Stroke Unit with ischemic stroke were followed up to 60 days. At this time point, they were evaluated with the following tools: Mini-Mental State Examination (MMSE); Frontal Assessment Battery (FAB); Visual Memory Test of the Brief Cognitive Battery (VMT); Phonemic Verbal Fluency (F-A-S Test); Digit Span; Facial Emotion Recognition Test (FERT) and Hospital Anxiety and Depression Scale (HADS). A control group composed of 21 healthy individuals also underwent the same evaluation. Results: Eighteen patients with ischemic stroke were enrolled in this study. They had similar age, sex and schooling years compared to controls. Depression symptoms and episodic memory deficits were significantly more frequent in patients compared to controls. The recognition of sadness expression positively correlated with the levels of anxiety and depression, while and the recognition of fear expression negatively correlated with depression in the stroke group. Conclusions: After an ischemic stroke, patients exhibit impairment in social cognition skills, specifically facial emotion recognition, in association with behavioral symptoms.

BACKGROUND The high demand for adequate material for the gold standard reverse transcription real-time polymerase chain reaction (RT-qPCR)-based diagnosis imposed by the Coronavirus disease 2019 (COVID-19) pandemic, combined with the inherent contamination risks for healthcare workers during nasopharyngeal swab (NP) sample collection and the discomfort it causes patients, brought the need to identify alternative specimens suitable for the diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). OBJECTIVES The aim of this work was to compare saliva and gingival fluid swabs to NP swabs as specimens for RT-qPCR-based SARS-CoV-2 diagnosis. METHODS We compared gingival fluid swabs (n = 158) and saliva (n = 207) to the rayon-tipped NP swabs obtained from mild-symptomatic and asymptomatic subjects as specimens for RT-qPCR for SARS-CoV-2 detection. FINDINGS When compared to NP swabs, gingival fluid swabs had a concordance rate of 15.4% among positive samples, zero among inconclusive, and 100% among negative ones. For saliva samples, the concordance rate was 67.6% among positive samples, 42.9% among inconclusive, and 96.8% among negative ones. However, the concordance rate between saliva and NP swabs was higher (96.9%) within samples with lower cycle threshold (Ct) values (Ct > 10 ≤ 25). MAIN CONCLUSIONS Our data suggests that whereas gingival fluid swabs are not substitutes for NP swabs, saliva might be considered whenever NP swabs are not available or recommended.

Resumen: En | Texto: En | PDF: En

Abstract In recent decades the diploid numbers recorded in the New World marsupials have been widely discussed in the context of the processes of karyotype evolution in these mammals. While Interstitial Telomeric Sequences (ITS) have long been interpreted as remnants of chromosomal fusion, the biological role of these features, together with their intraspecific variation, has raised a number of questions. In the present study, we analyzed the karyotype of 11 species of Amazonian didelphids, comparing the distribution of the heterochromatin with that of the telomeric signals, and found that, in six species, the ITS coincided with the blocks of heterochromatin. While ITS were found in the X chromosomes of all Marmosa murina individuals, they were variable in all the other species, representing a specific character of each lineage. Our results support the conclusion that ITS may not always be a consequence of chromosomal rearrangements, and that the mechanisms that produce them are still unclear.

ABSTRACT: The aim of this study was to investigate the effect of heat stress on 12 bean genotypes through the analysis of their reproductive biology in terms of flowering, pollen viability, meiotic behavior, and production. Plants were grown in a climate chamber at 25-20 °C (day and night) and at a high temperature treatment 37-26 °C (day and night) from the vegetative (V4) development stage to physiological maturity. The experimental design was 2 × 12 factorial arrangement with six replications and the factors consisted of heat treatments and genotypes. In three replications, the number of newly opened flowers was checked daily. At physiological maturity, the following traits were evaluated: percentage of pod set, number of pods, number of viable seeds, number of aborted seeds, 100 seed weight, and seed yield (g per plant). The other three replications were used to collect flowers to create slides to study viability of the pollen grain and analyze the meiotic behavior. The heat treatment factor significantly affected the following traits: total number of pollen grains, number of flowers, number of pods, pod set, number of viable seeds, 100 seed weight, and seed yield. The raised temperature reduced these variables, except for percentage of pod set, and increased meiotic irregularities. The mean values regarding seed yield were 16.39 g per plant for the control treatment and 7.46 g per plant under high temperature. IAC Imperador, FT Nobre, Pérola, BRS Estilo, and IAC Diplomata stood out for higher bean seed yield under increased temperature.

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

resumo Historicamente, a expansão das cidades resultou na substituição da paisagem natural pela urbana, tendo como consequência a degradação ambiental por meio das mudanças na cobertura do solo, nos sistemas hidrológicos, nos ciclos biogeoquímicos, no clima e na biodiversidade, tornando as cidades especialmente vulneráveis às mudanças climáticas. A reversão desses processos é uma medida que visa a promoção da qualidade de vida nas cidades, na qual a arborização possui um papel fundamental por fornecer uma série de serviços ecossistêmicos valiosos para a promoção da biodiversidade, saúde e bem-estar social. Sendo direito de todos um meio ambiente equilibrado, saudável, de uso comum e essencial à qualidade de vida, o verde urbano é assunto interdisciplinar e de responsabilidade comum e generalizada. Cabe ao poder público a regularização, criação e manutenção dos plantios, promovendo o plantio de árvores a distâncias predeterminadas de acordo com o porte de cada espécie. Porém, os movimentos ativistas se desenvolveram no vácuo da morosidade do poder público seguindo, em geral, o método de adensamento de árvores pautado pelo conceito de sucessão ecológica. Ao promover a restauração dos serviços ecossistêmicos, as duas iniciativas de plantio arbóreo tendem a trazer grandes benefícios às grandes cidades, como São Paulo. Porém, a complexidade da paisagem urbana exige uma avaliação sistêmica dos plantios para definir a sua adequação espacial e otimizar os seus benefícios. O plantio das florestas urbanas não deve ter como objetivo recriar as condições naturais pré-urbanização, mas sim, desenvolver áreas verdes integradas à malha urbana que garantam um ambiente saudável e equilibrado, preservando as interações sociais. Ao visualizar o meio urbano como um ecossistema completo, é possível estabelecer critérios que otimizem os benefícios da arborização urbana. Estes critérios devem ser baseados em conhecimento técnico e científico, levando em conta necessidades sociais, para que o melhor método seja escolhido, caso a caso.

abstract Historically, the expansion of cities resulted in the replacement of natural landscape by urban environments, resulting in environmental degradation through changes in soil cover, hydrological systems, biogeochemical cycles, biodiversity, making cities particularly vulnerable to climate changes. Environmental restoration in cities is a measure to promote life quality, and urban forests play a key role in restoring the quality of the urban environment. They provide valuable ecosystem services for maintaining biodiversity, ensuring human health, and social well-being. As everyone has the right to live in a balanced, healthy and common use environment essential to suppor quality of life, urban green areas are an interdisciplinary issue of collective concern. It is the responsibility of the government to regulate, plant and manage urban trees in order to standardize urban afforestation by planting trees at predetermined distances according to the size of each species. However, the vacuum in the greening process left by the State is being filled by activists who, in general, use a different protocol that aims at higher tree density based on the notion of ecological succession. By promoting the restoration of ecosystem services, both initiatives tend to bring significant benefits to large cities such as São Paulo. However, the complexity of the urban landscape requires a systemic evaluation of tree planting to define spatial adequacy and optimize benefits. The planting of urban forests should not aim to recreate pre-urban natural conditions, but rather to develop green areas integrated to the urban network that guarantee a healthy and balanced environment while preserving social interactions. By perceiving the urban environment as a complete ecosystem, it is possible to establish criteria that optimize the benefits of urban afforestation. These criteria should be based on technical and scientific knowledge, and take into account social needs, so that the best method is chosen on a case-by-case basis.

Resumo Introdução: O Comprometimento Cognitivo Leve (CCL) é caracterizado pela presença de queixas subjetivas de memória, sendo considerado um estágio entre a função cognitiva normal e a patológica. O declínio das funções cognitivas pode estar relacionado ao baixo desempenho funcional e a alteração da composição corporal em idosos. Objetivo: Avaliar a força muscular, o desempenho funcional de membros inferiores e a composição corporal de idosas com CCL. Métodos: participaram do estudo 43 idosas que foram divididas em 2 grupos, sendo 19 idosas com CCL e 24 idosas sem CCL, a idade variou de 60 a 80 anos. Para diagnóstico do CCL utilizou-se os instrumentos propostos por Petersenet al, no qual a idosa deveria apresentar queixas de memória, sem repercussões nas atividades básicas e instrumentais de vida diária.A força muscular foi avaliada pela força de preensão palmar (FPP) utilizando o dinamômetro (Jamar®) e a força extensora do joelho (FEJ) pelo movimento de 1 repetição máxima (1-RM). O desempenho funcional de membros inferiores (MMII) foi avaliado pelo instrumento Short Physical Performance Battery (SPPB) e a composição corporal pela ImpedânciaBioelétrica (Biodynamics Model 310). Resultados: Foi encontrada diferença significativa na força muscular entre os grupos, sendo que o grupo de idosas com CCL apresentou menor FPP (p = 0,002) e menor FEJ (p = 0,002). As demais variáveis como SPPB e a composição corporal não apresentaram diferença significativa entre os grupos. Quanto às correlações, obteve-se correlação positiva significativa entre o SPPB e a FEJ (r = 0,55; p = 0,0001), o SPPB e a FPP (r = 0,37; p = 0,0155), a FEJ e a FPP (r = 0,59; p < 0,0001), e entre a massa magra e a FPP (r = 0,36; p = 0,0184). Conclusão: A força muscular dos MMII e a FPP estão diminuídas nas idosas com CCL, diferentemente do desempenho funcional de MMII e da composição corporal que não foram diferentes entre os grupos.

Abstract Introduction: Mild cognitive impairment (MCI) is characterized by subjective memory complaints and is considered an intermediate stage between normal and pathological cognitive function. The decline in cognitive function may be associated with low functional performance and alterations in body composition in older adults. Objective: To assess muscle strength, lower extremity functional performance and body composition in elderly women with MCI. Methods: Forty-three elderly women (aged 60-80 years) participated in the study. Participants were divided into two groups: elderly women with MCI (n = 19) and elderly women without MCI (n = 24). To diagnose MCI, we used the instruments proposed by Petersen et al. According to it, the subjects had to have memory complaints that had no effects on basic or instrumental activities of daily living. Muscle strength was assessed via palmar grip strength (PGS) using a dynamometer (Jamar®) and knee extension strength (KES) was assessed using the one-repetition maximum test (1-RM). Lower extremity (LE) functional performance was assessed using the Short Physical Performance Battery (SPPB) and body composition was measured using biometrical impedance analysis (Biodynamics Model 310). Results: There was a significant difference in muscle strength between groups. The group with MCI had lower PGS (p = 0.002) and KES (p = 0.002), when compared to their counterparts. No significant difference between groups was found for the other variables, like SPPB and body composition. We found a positive, significant correlation between SPPB and KES (r = 0.55; p = 0.0001), SPPB and PGS (r = 0.37; p = 0.0155), KES and PGS (r = 0.59; p < 0.0001), and between lean mass and PGS (r = 0.36; p = 0.0184). Conclusion: Elderly women with MCI show reduced LE muscle strength and PGS, but no differences between groups were found for LE functional performance and body composition.

Resumen: En | Texto: En | PDF: En

ABSTRACT The aim of this research was to monitor the presence of females of Aedes aegypti (Linnaeus, 1762) on the Seropédica municipality, Rio de Janeiro State, from 2010 to 2013. For this purpose, the Intelligent Dengue Monitoring (IM-Dengue) and Intelligent Virus Monitoring (IM-Virus) developed by Universidade Federal de Minas Gerais (Ecovec – Minas Gerais, Brazil), were used. IM-Dengue is a tool that allows achieving a weekly overview of A. aegypti infestation, while IM-Virus is another tool that allows detecting dengue virus directly from the mosquito, by Real Time-PCR. Both tools were developed for diagnosis in a prepathogenesis period of the disease, before infection occurrence. Traps were distributed in 19 locations inside the municipality and the bugs were collected weekly during the years of the research. As a result, the presence of 163 females of A. aegypti was recorded over the period; there was no circulation of the virus in the municipality. In one of the 19 study sites, a high degree of disease transmission risk was verified. The study concluded that the municipality, as a whole, showed no risk of disease transmission throughout the field research period.

ABSTRACT Background Atypical presentations of cutaneous leishmaniasis include sporotrichoid leishmaniasis (SL), which is clinically described as a primary ulcer combined with lymphangitis and nodules and/or ulcerated lesions along its pathway. Aims To assess the differences between patients with sporotrichoid leishmaniasis and typical cutaneous leishmaniasis (CL). Methods From January 2004 to December 2010, 23 cases of SL (4.7%) were detected among 494 CL patients diagnosed at a reference center for the disease in Rio de Janeiro State, Brazil. These 23 cases were compared with the remaining 471 patients presenting CL. Results SL predominated in female patients (60.9%, p = 0.024), with older age (p = 0.032) and with lesions in upper limbs (52.2%, p = 0.028). CL affected more men (64.5%), at younger age, and with a higher number of lesions exclusively in lower limbs (34.8%). Conclusions Differences in clinical and epidemiological presentation were found between SL patients as compared to CL ones, in a region with a known predominance of Leishmania (Viannia) braziliensis. The results are similar to the features of most of the sporotrichosis patients as described in literature, making the differential diagnosis between ATL and sporotrichosis more important in overlapping areas for both diseases, like in Rio de Janeiro State.

Resumo A identificação de Listeria spp. em áreas de manipulação de alimentos é de grande preocupação para as agências de vigilância da saúde. O seu controle, muitas vezes, é prejudicado pela capacidade da bactéria em crescer e se manter no ambiente mesmo sob condições adversas. Objetivou-se, com este estudo, isolar e identificar Listeria spp. em áreas de manipulação de estabelecimentos varejistas de alimentos no Estado de Pernambuco, Brasil. Foram colhidas 86 amostras de swabs, procedentes de equipamentos, utensílios e instalações utilizados para processamento de embutidos cárneos, distribuídas em dez estabelecimentos varejistas. Para identificação de Listeria spp., utilizaram-se os métodos rápidos 3M™, Quick Swab e 3M™ Petrifilm™. A confirmação de Listeria monocytogenes foi realizada pela técnica de Reação em Cadeia da Polimerase em Tempo Real (qPCR). Nos estabelecimentos, foi realizada uma lista de verificação para avaliar as condições higiênico-sanitárias dos pontos de coletas. Das 86 amostras analisadas, 27 (31,2%) [intervalo de confiança 21,81% a 42,30%] foram positivas para Listeria spp. e, destas, uma (3,7%) para Listeria monocytogenes. Os pontos de maior contaminação foram o piso (50,0%), a placa de polietileno (42,9%) e a faca (40,0%). Dos dez estabelecimentos analisados, observou-se que oito (80,0%) tiveram ao menos uma amostra positiva para Listeria spp. Ao analisar a associação entre as condições higiênico-sanitárias dos pontos de coletas e o exame microbiológico, foi constatado não haver diferença significativa (p = 0,700). Diante dos resultados obtidos, conclui-se que a Listeria spp. está amplamente distribuída nos ambientes estudados, o que pode favorecer a contaminação dos alimentos e, consequentemente, oferecer riscos à saúde pública. Desta forma, recomenda-se que parâmetros microbiológicos devem ser estabelecidos pelos órgãos reguladores de saúde para alimentos cárneos e seus embutidos, com o intuito de oferecer um alimento seguro para os consumidores.

Abstract The identification of Listeria spp. in food handling areas is of great concern to health surveillance agencies, and their control is often hampered by the ability of the bacteria to grow and maintain themselves even under adverse conditions. The present study aimed to isolate and identify Listeria spp. in the food handling areas of 10 retail food stores in the state of Pernambuco, Brazil. Eighty-six swab samples were collected from equipment, utensils and surfaces used for processing ready-to-eat meat products. The Dry and Wet Swabbing Methods (3M™ Quick Swabs) and 3M™ Petrifilm™ Plates were used to identify Listeria spp. Contamination by Listeria monocytogenes was confirmed by the Real-time Polymerase Chain Reaction (qPCR). The hygienic and sanitary conditions of the food handling areas of each store were also assessed. Listeria spp. was isolated in eight stores (80%). Of the 86 swab samples analyzed, 27 (31.2%) [confidence interval 21.81% to 42.30%] were positive for Listeria spp. and only one (3.7%) was confirmed as Listeria monocytogenes. The main contamination sites were the floor (50.0%), the plastic cutting board (42.9%) and the knife (40.0%). None of the hygienic and sanitary conditions assessed in the present study were associated with contamination by Listeria spp. (p = 0.700). It was concluded that Listeria spp. was widely distributed in the retail food stores studied, being a possible risk factor for public health.
