| Abstract For the definitive diagnosis of bovine tuberculosis, isolation of the etiologic agent is required. However, there is no consensus on the best methodology for isolation of Mycobacterium bovis in Brazil. This study evaluated the most used decontaminants and culture media in the country, in order to identify the best combination for the Brazilian samples. Three decontaminants - 2% sodium hydroxide (w/v), 0.75% hexadecylpiridinium chloride (w/v) and 5% sulphuric acid (v/v) and four culture media - 7H11 Middlebrook with additives and OADC supplement “A” (7H11 A), the same media with another supplement trademark (7H11 B), tuberculosis blood agar (B83) and Stonebrink's medium were compared. Regarding the isolation, there were no significant differences... |

| Esta investigação teve por objetivo validar o teste de polarização fluorescente (TPF) para o diagnóstico sorológico da brucelose bovina, determinando a sensibilidade (SE) e a especificidade relativas (SP) e verificando a reprodutibilidade do teste em quatro laboratórios no Brasil. Foram selecionadas 1.389 amostras de soro sanguíneo, as quais foram inicialmente submetidas aos testes do antígeno acidificado tamponado (AAT) e mercaptoetanol (2-ME). As mesmas amostras foram submetidas à reação de fixação de complemento (RFC) e ao TPF. Para a avaliação do TPF, foi adotada a combinação dos resultados do AAT, da RFC e do 2-ME, utilizados como população de referência (padrão-ouro). Para a determinação do ponto de corte do TPF que proporciona a melhor combinação de... |

| Mycobacterium tuberculosis is the major cause of tuberculosis in humans. This bacillus gained prominence with the occurrence of HIV, presenting itself as an important opportunistic infection associated with acquired immunodeficiency syndrome (AIDS). The current study aimed to develop a real-time PCR using Eva Green technology for molecular identification of M. tuberculosis isolates. The primers were designed to Rv1510 gene. Ninety nine samples of M. tuberculosis and sixty samples of M. bovis were tested and no sample of the bovine bacillus was detected by the qPCR. Statistical tests showed no difference between the qPCR and biochemical tests used to identify the Mycobacterium tuberculosis. The correlation between tests was perfect with Kappa index of 1.0... |

| ABSTRACT: A multiplex PCR technique for detection of Brucella spp. in samples of bacterial suspension was validated as a complementary tool in the diagnosis of the disease. This technique allows the characterization of the agent without performing biochemical tests, which greatly reduces the time for a final diagnosis, and provides more security for the analyst by reducing the time of exposure to microorganisms. The validation was performed in accordance with the Manual of Diagnostic Tests from OIE (2008) and following the requirements present in the ABNT NBR ISO/IEC 17025:2005. The mPCR validated in this study identified the different species of Brucella ( Brucella abortus , B. suis , B. ovis e B. melitensis ) of bacterial suspension obtained from the... |
