Reação em cadeia da polimerase para detecção de Clostridium chauvoei em tecidos de Cavia porcellus

Abstract: Resumo -O objetivo deste trabalho foi padronizar uma técnica de reação em cadeia da polimerase (PCR), para detecção de Clostridium chauvoei, em tecidos fixados em formol e incluídos em parafina de cobaias (Cavia porcellus) experimentalmente infectadas com esse microrganismo. Os animais foram sacrificados, e amostras do músculo da área de inoculação (MAI), fígado, miocárdio e baço foram disponibilizadas para a técnica de PCR. O clostrídio foi detectado em todas as secções do MAI, fígado e miocárdio, mas não foi… Show more

“…This could be a result of low numbers of bacteria that were seen only because of the enrichment in the microbiological culture and were below the detection limit of the direct PCR procedure when applied to the impregnated filter paper. Of note, guinea pigs (Cavia porcellus) that were infected intramuscularly with C. chauvoei, had no bacteria detected in the spleen samples (ASSIS et al, 2005), suggesting that it is not a tissue where the bacteria are usually found.…”
