Abstract Background Ischemic stroke is an important cause of death in the world. The malignant middle cerebral artery infarction (MMCAI) has mortality as high as 80% when clinically treated. In this setting, decompressive craniectomy is a life-saving measure, in spite of high morbidity among survivors. Objective To evaluate the outcomes of patients with MMCAI treated with decompressive craniectomy in a Brazilian academic tertiary stroke center. Methods A prospective stroke database was retrospectively evaluated, and all patients treated with decompressive craniectomy for MMCAI between January 2014 and December 2017 were included. The demographics and clinical characteristics were evaluated. The functional outcome, measured by the modified Rankin Scale (mRS), was assessed at hospital discharge, after 3-months and 1-year of follow-up. Results We included 53 patients on the final analysis. The mean age was 54.6 ± 11.6 years and 64.2% were males. The median time from symptoms to admission was 4.8 (3–9.7) hours and the mean time from symptoms to surgery was 36 ± 17 hours. The left hemisphere was the affected in 39.6%. The median NIHSS at admission was 20 (16–24). The in-hospital mortality was 30.2%. After a median of 337 [157–393] days, 47.1% of patients had achieved favorable outcome (mRS ≤ 4) and 39.6% had died. Conclusion Decompressive craniectomy is a life-saving measure in the setting of MMCAI, and its effects remains important in the scenario of a middle-income country in real-world situations.

Resumo Antecedentes O acidente vascular cerebral (AVC) isquêmico é uma causa importante da morte em todo o mundo. O infarto maligno da artéria cerebral média (IMACM) tem mortalidade de até 80% quando tratado clinicamente. Nesse contexto, a craniectomia descompressiva é uma medida salvadora de vidas, apesar da alta morbidade entre os sobreviventes. Objetivo Avaliar os desfechos dos pacientes com IMACM tratados com craniectomia descompressiva em um centro acadêmico terciário de AVC no Brasil. Métodos Um banco de dados prospectivo de AVC foi avaliado retrospectivamente e todos os pacientes tratados com craniectomia descompressiva para IMACM entre janeiro de 2014 e dezembro de 2017 foram incluídos. As características clínicas e demográficas foram avaliadas. Os desfechos funcionais, medidos pela escala modificada da Rankin (mRS), foram avaliados na alta hospitalar, após 3 meses e após 1 ano de seguimento. Resultados Foram incluídos 53 pacientes na análise final. A idade média foi 54,6 ± 11,6 anos e 64,2% eram homens. A mediana do tempo dos sintomas à admissão foi 4,8 (3–9,7) horas e o tempo médio dos sintomas à cirurgia foi 36 ± 17 horas. O hemisfério esquerdo foi o afetado em 39,6%. A pontuação na escala de AVC do National Institute of Health (NIHSS) à admissão foi 20 (16–24). A mortalidade hospitalar foi 30,2%. Após uma mediana de 337 (157–393) dias, 47,1% dos pacientes tinham atingido um desfecho favorável (mRS ≤ 4) e 39,6% tinham morrido. Conclusão Craniectomia descompressiva é uma medida salvadora de vidas no contexto do IMACM e seus efeitos permanecem importantes no cenário de um país em desenvolvimento em situação de vida real.

ABSTRACT. Cotton is one of the largest agricultural commodities that generate various sources of foreign exchange and employment worldwide. However, water deficiency is an environmental factor that limits the production of this crop, especially in semi-arid regions. We evaluated pyruvate supplementation to mitigate the effects of water stress on colored cotton. Experiments were conducted in a greenhouse. We studied two forms of pyruvate supplementation (SP1- via seed and foliar and SP2- only via foliar); three conditions of irrigation management of the plants: water restriction in the vegetative phase (VE), flowering (FL), and vegetative and flowering (VE/FL); and additional treatment (total irrigation throughout the crop cycle and without pyruvate supplementation). The experimental design included a randomized block in a 2 × 3 + 1 factorial scheme. The factors resulted in seven treatments with three replications, with a total of 21 experimental units. Gas exchange, enzyme activity, and production of components were evaluated. Water restriction in the vegetative phase does not cause losses in BRS Jade cotton when supplemented with pyruvate. However, in the flowering and vegetative phases plus flowering, it reduces gas exchange and production components and increases the activity of antioxidant enzymes in relation to plants under full irrigation. Supplementation with pyruvate via seed plus foliar (SP1) was better for BRS Jade cotton grown under water restriction.

Abstract Background Intracerebral hemorrhage (ICH) is a deadly disease and increased intracranial pressure (ICP) is associated with worse outcomes in this context. Objective We evaluated whether dilated optic nerve sheath diameter (ONSD) depicted by optic nerve ultrasound (ONUS) at hospital admission has prognostic value as a predictor of mortality at 90 days. Methods Prospective multicenter study of acute supratentorial primary ICH patients consecutively recruited from two tertiary stroke centers. Optic nerve ultrasound and cranial computed tomography (CT) scans were performed at hospital admission and blindly reviewed. The primary outcome was mortality at 90-days. Multivariate logistic regression, ROC curve, and C-statistics were used to identify independent predictors of mortality. Results Between July 2014 and July 2016, 57 patients were evaluated. Among those, 13 were excluded and 44 were recruited into the trial. Their mean age was 62.3 ± 13.1 years and 12 (27.3%) were female. On univariate analysis, ICH volume on cranial CT scan, ICH ipsilateral ONSD, Glasgow coma scale, National Institute of Health Stroke Scale (NIHSS) and glucose on admission, and also diabetes mellitus and current nonsmoking were predictors of mortality. After multivariate analysis, ipsilateral ONSD (odds ratio [OR]: 6.24; 95% confidence interval [CI]: 1.18–33.01; p = 0.03) was an independent predictor of mortality, even after adjustment for other relevant prognostic factors. The best ipsilateral ONSD cutoff was 5.6mm (sensitivity 72% and specificity 83%) with an AUC of 0.71 (p = 0.02) for predicting mortality at 90 days. Conclusion Optic nerve ultrasound is a noninvasive, bedside, low-cost technique that can be used to identify increased ICP in acute supratentorial primary ICH patients. Among these patients, dilated ONSD is an independent predictor of mortality at 90 days.

Resumo Antecedentes A hemorragia intraparenquimatosa (HIP) aguda apresenta elevada morbimortalidade e a presença de hipertensão intracraniana (HIC) confere um pior prognóstico. Objetivo Avaliamos se a dilatação do diâmetro da bainha do nervo óptico (DBNO) através do ultrassom do nervo óptico (USNO) na admissão hospitalar seria preditora de mortalidade. Métodos Estudo multicêntrico e prospectivo de pacientes consecutivos com HIP supratentorial primária aguda admitidos em dois centros terciários. Ultrassom do nervo óptico e tomografia computadorizada (TC) de crânio foram realizados na admissão e revisados de forma cega. O desfecho primário do estudo foi a mortalidade em 3 meses. Análises de regressão logística, curva de característica de operação do receptor (ROC, na sigla em inglês) e estatística-C foram utilizadas para identificação dos preditores independentes de mortalidade. Resultados Entre julho de 2014 e julho de 2016, 44 pacientes foram incluídos. A idade média foi 62,3 (±13,1) anos e 12 (27,3%) eram mulheres. Na análise univariada, o volume da HIP na TC de crânio, DBNO ipsilateral à HIP, glicemia, escala de coma de Glasgow (ECG) e NIHSS na admissão hospitalar, e também diabetes mellitus e não-tabagista foram preditores de mortalidade. Após análise multivariada, o DBNO ipsilateral à HIP permaneceu como preditor independente de mortalidade (odds ratio [OR]: 6,24; intervalo de confiança [IC] de 95%: 1,18–33,01; p = 0,03). O melhor ponto de corte do DBNO ipsilateral como preditor de mortalidade em 3 meses foi 5,6mm (sensibilidade 72% e especificidade 83%) e área sob a curva (AUC, na sigla em inglês) 0,71 (p = 0,02). Conclusão O USNO é um método não-invasivo, beira-leito, de baixo custo, que pode ser empregado para estimar a presença de HIC em pacientes com HIP supratentorial primária aguda. A presença de DBNO dilatada é um preditor independente de mortalidade em 3 meses nesses pacientes.

Abstract: En | Text: En | PDF: En

ABSTRACT The SISBIOTA-BRASIL was a three-year multimillion-dollar research program of the Brazilian government to document plants and animals in endangered/understudied areas and biomes in Brazil. Distributional patterns and the historical events that generated them are extensively unknown regarding Brazilian fauna and flora. This deficiency hinders the development of conservation policies and the understanding of evolutionary processes. Conservation decisions depend on precise knowledge of the taxonomy and geographic distribution of species. Given such a premise, we proposed to research the diversity of Diptera of the Brazilian western arc of Amazon, Cerrado, and Pantanal in the states of Mato Grosso, Mato Grosso do Sul, and Rondônia. Three important biomes of the South American continent characterize these Brazilian states: Amazon forest, Cerrado (Brazilian Savannah), and Pantanal. Besides their ecological relevance, these biomes historically lack intensive entomological surveys. Therefore, they are much underrepresented in the Brazilian natural history collections and in the scientific literature, which is further aggravated by the fact that these areas are being exponentially and rapidly converted to commercial lands. Our project involved over 90 collaborators from 24 different Brazilian institutions and one from Colombia among researchers, postdocs, graduate and undergraduate students, and technicians. We processed and analyzed nearly 300,000 specimens from ~60 families of Diptera collected with a large variety of methods in the sampled areas. Here, we provide a detailed overview of the genera and species diversity of 41 families treated. Our results point to a total of 2,130 species and 514 genera compiled and identified for the three states altogether, with an increase of 41% and 29% in the numbers of species and genera known for the three states combined, respectively. Overall, the 10 most species-rich families were Tachinidae, Cecidomyiidae, Tabanidae, Psychodidae, Sarcophagidae, Stratiomyidae, Bombyliidae, Syrphidae, Tephritidae, and Asilidae. The 10 most diverse in the number of genera were Tachinidae, Stratiomyidae, Asilidae, Mycetophilidae, Syrphidae, Tabanidae, Muscidae, Dolichopodidae, Sarcophagidae, and Chloropidae. So far, 111 scientific papers were published regarding taxonomic, phylogenetic, and biogeographical aspects of the studied families, with the description of 101 new species and three new genera. We expect that additional publications will result from this investigation because several specimens are now curated and being researched by specialists.

RESUMO Objetivou-se avaliar, por meio de análise multivariada de dados, quais resíduos de leguminosas arbóreas tem melhor potencial fertilizante para culturas agrícolas no semiárido nordestino brasileiro. O experimento foi conduzido em vasos, em delineamento aleatorizado em blocos, com sete tratamentos e quatro repetições. Para constituir os tratamentos utilizaram-se resíduos de sabiá, jurema-preta e gliricídia; além de duas partes da planta: folhas e folhas mais galhos. Os vasos foram preenchidos com 8,0 dm3 de solo e os resíduos foram adicionados na forma de massa verde, correspondendo a 73,0 g de massa seca por vaso. Sementes de milho foram semeadas e aos 65 dias após adição dos resíduos avaliou-se atributos químicos do solo, crescimento e teores de nutrientes das plantas. Os dados foram estudados por meio das análises de componentes principais, agrupamento, função discriminante canônica e teste de comparação de médias a partir da varável canônica 1. Resíduos de gliricídia influenciaram positivamente K e Mg do solo, bem como altura, diâmetro do caule, número de folhas e teores foliares de P, N e Mg em plantas de milho. Estes resíduos apresentaram maior dissimilaridade e separação em relação ao tratamento controle e proporcionaram médias estatisticamente superiores aos demais tratamentos. Folhas de jurema-preta influenciaram positivamente Ca, N e COT do solo, bem como teores foliares de K e Ca e matéria seca total do milho. A análise estatística multivariada permitiu identificar potenciais distintos entre resíduos de leguminosas para uso como fertilizante na cultura do milho, sendo a espécie gliricídia a que apresenta maior potencial.

ABSTRACT The objective of this study was to evaluate, through multivariate data analysis, which tree legume residues have the best fertilizer potential for agricultural crops in the semi-arid region of northeastern Brazil. The experiment was conducted in pots, in a randomized block design, with seven treatments and four replicates. Treatments consisted of residues of Sabiá, Jurema Preta and Gliricidia, besides two parts of the plant: leaves and leaves + branches. The pots were filled with 8.0 dm3 of soil and the residues were added in the form of green mass, corresponding to 73.0 g of dry mass per pot. Maize seeds were sown and, at 65 days after addition of the residues, soil chemical attributes, growth and nutrient contents in the plants were evaluated. The data were studied through principal component analysis, clustering analysis, canonical discriminant function analysis and means comparison test from canonical variable 1. Gliricidia residues positively influenced soil K and Mg contents, as well as height, stem diameter, number of leaves and leaf contents of P, N and Mg in maize plants. These residues showed greater dissimilarity and separation compared to the control treatment and led to statistically higher means compared to the other treatments. Jurema Preta leaves positively influenced soil Ca, N and TOC, as well as leaf contents of K and Ca and total dry mass of maize. Multivariate statistical analysis made it possible to identify distinct potentials among legume residues for use as fertilizer in maize crop, and Gliricidia is the species with highest potential.

RESUMO Introdução: A pandemia causada pelo novo coronavírus da síndrome respiratória aguda grave 2 (SARS-CoV-2, COVID-19) apresenta novos e importantes desafios à gestão de saúde no Brasil. Além da difícil missão de prestar atendimento aos milhares de pacientes infectados pelo COVID-19, os sistemas de saúde têm que manter a assistência às emergências médicas comuns em períodos sem pandemia, tais como o acidente vascular cerebral (AVC), que continuam ocorrendo e requerem tratamento com presteza e eficiência. A alocação de recursos materiais e humanos para o enfrentamento à pandemia não pode comprometer o atendimento ao AVC agudo, uma emergência cujo tratamento é tempo-dependente e se não realizado implica em importante impacto na mortalidade e incapacitação a longo prazo. Objetivo: Este trabalho resume as recomendações do Departamento Científico de Doenças Cerebrovasculares da Academia Brasileira de Neurologia, da Sociedade Brasileira de Doenças Cerebrovasculares e da Sociedade Brasileira de Neurorradiologia para o tratamento do AVC agudo e para a realização de procedimentos de neurointervenção urgentes durante a pandemia de COVID-19, incluindo o uso adequado de ferramentas de triagem e equipamentos de proteção pessoal (para pacientes e profissionais de saúde), além da alocação apropriada de pacientes.

ABSTRACT Introduction: Although the 2019 severe acute respiratory syndrome coronavirus 2 infection (SARS-CoV-2, COVID-19) pandemic poses new challenges to the healthcare system to provide support for thousands of patients, there is special concern about common medical emergencies, such as stroke, that will continue to occur and will require adequate treatment. The allocation of both material and human resources to fight the pandemic cannot overshadow the care for acute stroke, a time-sensitive emergency that with an inefficient treatment will further increase mortality and long-term disability. Objective: This paper summarizes the recommendations from the Scientific Department on Cerebrovascular Diseases of the Brazilian Academy of Neurology, the Brazilian Society of Cerebrovascular Diseases and the Brazilian Society of Neuroradiology for management of acute stroke and urgent neuro-interventional procedures during the COVID-19 pandemic, including proper use of screening tools, personal protective equipment (for patients and health professionals), and patient allocation.

RESUMO O acidente vascular cerebral isquêmico secundário à oclusão aguda da basilar (OAB) é uma condição relativamente rara, que cursa com elevada morbimortalidade. Até o momento atual, a melhor estratégia de recanalização arterial na fase aguda da OAB não está definida, principalmente pela carência de ensaios clínicos randomizados e controlados neste contexto. Neste artigo, revisamos aspectos históricos do diagnóstico e do tratamento desta condição, assim como o impacto do avanço tecnológico na evolução clínica e prognóstico desta condição. Ademais, descrevemos fatos históricos e a literatura fictícia relacionados à OAB. Concluímos que a OAB é um exemplo peculiar de como a arte pode auxiliar a medicina na descrição acurada de condições médicas.

ABSTRACT Basilar artery occlusion (BAO) ischemic stroke is a relatively rare condition with high morbidity and mortality rates. To date, the best acute reperfusion therapy for BAO has still not been established, mainly due to the lack of randomized controlled trials in this field. In this article, we review the history of BAO diagnosis and treatment, and the impact of modern technological resources on the clinical evolution and prognosis of BAO over time. Furthermore, we describe historical events and nonmedical literature descriptions related to BAO. We conclude that BAO is a singular example of how art may help medical sciences with accurate descriptions of medical conditions.

RESUMO A trombectomia mecânica com stent retrievers é o tratamento padrão ouro do acidente vascular cerebral isquêmico agudo (AVCi) por oclusão de grandes artérias. A técnica de aspiração primária (ADAPT) tem sido proposta como uma estratégia de trombectomia rápida e com boa custo-efetividade. O objetivo deste estudo foi avaliar a segurança e eficácia da técnica ADAPT. Métodos A recanalização foi avaliada utilizando a escala mTICI. Os desfechos neurológicos foram avaliados utilizando as escalas do NIHSS e mRS. Resultados Quinze pacientes foram avaliados. Foram obtidas taxas de mTICI = 2b-3 em 80% e TICI = 3 em 60% dos pacientes. Não ocorreram hemorragias intracranianas. Em 3 meses as taxas de mRS≤2 e mortalidade foram respectivamente 60% e 13.3%. Conclusão A técnica ADAPT parece ser uma estratégia de recanalização rápida, segura e efetiva para o tratamento do AVC por oclusão de grandes artérias.

ABSTRACT Mechanical thrombectomy using stent retrievers is the standard treatment for acute ischemic stroke that results from large vessel occlusions. The direct aspiration first pass technique (ADAPT) has been proposed as an efficient, fast, and cost-effective thrombectomy strategy. The aim of this study was to assess the safety and efficacy of ADAPT. Methods Recanalization was assessed using the modified thrombolysis in cerebral infarction (mTICI) score. Neurological outcomes were assessed using the National Institutes of Health Stroke Scale and modified Rankin Scale. Results Fifteen patients were evaluated. The mTICI score was 2b-3 in 80%, and it was 3 in 60% of patients. No intracranial hemorrhage was seen. At three months, modified Rankin Scale scores ≤ 2 were observed in 60% of patients and the mortality rate was 13.3%. Conclusions The ADAPT appears to be a safe, effective, and fast recanalization strategy for treatment of acute ischemic stroke resulting from large vessel occlusions.

OBJECTIVES: Carotid artery stenting is an emerging revascularization alternative to carotid endarterectomy. However, guidelines have recommended carotid artery stenting only if the rate of periprocedural stroke or death is < 6% among symptomatic patients and < 3% among asymptomatic patients. The aim of this study is to evaluate and compare clinical outcomes of symptomatic and asymptomatic patients who had undergone carotid artery stenting as a first-intention treatment. METHOD: A retrospective analysis of patients who underwent carotid artery stenting by our interventional neuroradiology team was conducted. Patients were divided into two groups: symptomatic and asymptomatic patients. The primary endpoints were ipsilateral ischemic stroke, ipsilateral parenchymal hemorrhage and major adverse cardiac and cerebrovascular events at 30 days. The secondary endpoints included ipsilateral ischemic stroke, ipsilateral parenchymal hemorrhage, ipsilateral transient ischemic attack and major adverse cardiac and cerebrovascular events between the 1- and 12-month follow-ups. RESULTS: A total of 200 consecutive patients were evaluated. The primary endpoints obtained in the symptomatic vs. asymptomatic groups were ipsilateral stroke (2.4% vs. 2.7%, p = 1.00), ipsilateral parenchymal hemorrhage (0.8% vs. 0.0%, p = 1.00) and major adverse cardiac and cerebrovascular events (4.7% vs. 2.7%, p = 0.71). The secondary endpoints obtained in the symptomatic vs. asymptomatic groups were ipsilateral ischemic stroke (0.0% vs. 0.0%), ipsilateral parenchymal hemorrhage (0.0% vs. 0.0%), ipsilateral TIA (0.0% vs. 0.0%, p = 1.00) and major adverse cardiac and cerebrovascular events (11.2% vs. 4.1%, p = 0.11). CONCLUSIONS: In this retrospective study, carotid artery stenting was similarly safe and effective when performed as a first-intention treatment in both symptomatic and asymptomatic patients. The study results comply with the safety requirements from current recommendations to perform carotid artery stenting as an alternative treatment to carotid endarterectomy.

Abstract: En | Text: En | PDF: En

OBJECTIVE: Scarce data are available on the occurrence of symptomatic intracranial hemorrhage related to intravenous thrombolysis for acute stroke in South America. We aimed to address the frequency and clinical predictors of symptomatic intracranial hemorrhage after stroke thrombolysis at our tertiary emergency unit in Brazil. METHOD: We reviewed the clinical and radiological data of 117 consecutive acute ischemic stroke patients treated with intravenous thrombolysis in our hospital between May 2001 and April 2010. We compared our results with those of the Safe Implementation of Thrombolysis in Stroke registry. Univariate and multiple regression analyses were performed to identify factors associated with symptomatic intracranial transformation. RESULTS: In total, 113 cases from the initial sample were analyzed. The median National Institutes of Health Stroke Scale score was 16 (interquartile range: 10-20). The median onset-to-treatment time was 188 minutes (interquartile range: 155-227). There were seven symptomatic intracranial hemorrhages (6.2%; Safe Implementation of Thrombolysis in Stroke registry: 4.9%; p = 0.505). In the univariate analysis, current statin treatment and elevated National Institute of Health Stroke Scale scores were related to symptomatic intracranial hemorrhage. After the multivariate analysis, current statin treatment was the only factor independently associated with symptomatic intracranial hemorrhage. CONCLUSIONS: In this series of Brazilian patients with severe strokes treated with intravenous thrombolysis in a public university hospital at a late treatment window, we found no increase in the rate of symptomatic intracranial hemorrhage. Additional studies are necessary to clarify the possible association between statins and the risk of symptomatic intracranial hemorrhage after stroke thrombolysis.

Este artigo discute o papel dos trabalhadores de linha de frente na construção da relação de serviço em uma empresa operadora de serviços de saúde. Fundamentada em um estudo de caso, no qual se aplicou a metodologia de Análise Ergonômica do Trabalho em observações da atividade de quatro atendentes, a pesquisa verificou a importância da atividade do atendente na construção da qualidade do serviço, ainda que a principal tarefa do atendente no caso analisado seja negar uma solicitação do cliente. Foi observado que os atendentes operam como um "filtro protetor" da retaguarda em relação à variação de demanda dos clientes e que os atendentes criam uma categorização própria das demandas apresentadas, categorização essa que acaba por direcionar o processo de atendimento. Como conclusão, propõe-se que a organização deve aproveitar a competência demonstrada pelos atendentes na criação da categorização e estruturar-se de maneira a estimular a integração entre atendimento e retaguarda, reduzindo o caráter de "filtro" da linha de frente, de modo a obter incrementos na qualidade do serviço prestado e na valorização do serviço por parte do cliente.

The aim of this paper is to discuss on the role of front office attendants in building a service relationship in a health care service operator. Based on a case study, in which Ergonomic Analysis of Work has been applied in observations of four attendants during worktime, the research verified the importance of the workers' activities to quality of service operations, even if their main activity is to deny a customer's demand. It was observed that attendants work as a "filter" which protects back office from the variability brought by the diverse customers' requests; and that front office workers classify these diverse customers' claims based on categories create by themselves - and this labeling drives the whole service delivery process. It is concluded that the organization should profit from the attendants' competencies, demonstrated in the process of labeling the diverse demands, and that it should structure itself in order to stimulate transversal process though front and back office, thus reducing the attendants' role of "protecting back office", so as to increase service delivery quality and service value.

Clostridium perfringens tipo D é o agente etiológico da enterotoxemia em ruminantes, causada pela toxina épsilon e caracterizada por edema cardíaco, pulmonar, renal e cerebral. Anticorpos monoclonais contra toxina épsilon de C. perfringens tipo D foram produzidos a partir da fusão da linhagen de mieloma P3-X63-Ag8 653 com células do baço de camundongos Balb/c imunizados com o toxóide épsilon. Seis linhagens de híbridos secretores de anticorpos monoclonais das classes e IgM e IgG foram estabelecidas.

Clostridium perfringens type D is the aetiological agent of enterotoxemia in ruminants. The disease is caused by epsilon toxin characterized by cardiac, pulmonary, kidney and brain edema. Monoclonal antibodies were produced by using myeloma cell line P3-X63-Ag8 653 fused with spleen cells from Balb/c mice, immunized with epsilon toxoid of C. perfringens type D. Six hybrids were established secreting monoclonal antibodies of the IgM class and IgG3 subclass.

Determinou-se a eficácia de doze vacinas contra clostridioses comercializadas no Brasil que contêm em sua composição Clostridium sordellii, pelo método de desafio em cobaias imunizadas. Como referência dos testes, empregou-se uma bacterina monovalente padrão. Duas vacinas (16,6%), codificadas como T6 e T8, apresentaram resultado igual à bacterina padrão, protegendo todos os animais desafiados. Uma vacina (8,3%), codificada como T10, não atendeu aos requisitos mínimos exigidos no primeiro teste, mas após o reteste foi considerada eficiente. As demais vacinas (75%), codificadas como T1, T2, T3, T4, T5, T7, T9, T11 e T12, não foram eficientes.

Twelve commercial vaccines against clostridiosis commercialized in Brazil which have in their composition Clostridium sordellii were evaluated for efficacy. A standard monovalent bacterin was used as a reference test. Two of the tested vaccines (16.6%), codified as T6 and T8, gave the same results as the standard bacterin, protecting all the challenged animals. One vaccine (8.3%), codified as T10, after being retested was considered efficient. The remaining vaccines (75%), codified as T1, T2, T3, T4, T5, T7, T9, T11 and T12, were considered inefficient.
