Resumo
Entre as espécies de Clostridium de importância em patologia animal, destaca-se o Clostridium perfringens, o Clostridium botulinum, o Clostridium chauvoei. O objetivo desta pesquisa foi verificar a presença de bactérias anaeróbias esporuladas (Clostridium sp), assim como, identificar as espécies de Clostridium patogênicos para a saúde animal, principalmente de bovinos, no solo de pastagem da micro-região de Jaboticabal, SP. Foram coletadas 250 amostras de solo e realizadas contagens de bactérias esporuladas do gênero Clostridium e identificação das espécies patogênicas presentes. Os resultados permitiram demonstrar a contagem de UFC de Closrtidium sp com média em log 10 igual a 2,79, sendo que os valores mínimo e máximo obtido foram 2,15 e 3,68 respectivamente. Para caracterização e identificação, os resultados permitiram identificar a presença de bactérias anaeróbias esporuladas em 233 amostras (93,2%), entre estas 180 eram do gênero Clostridium...
The species of Clostridium of major importance to animal pathology are Clostridium perfringens, Clostridium botulinum, and C. chauvoei. Considering this, the objective of this research was to verify the presence of anareobic sporulate bacteria (Clostridium sp), and also identify the species of pathogenic Clostridium for the animal health, mostly to bovine, in pasture soil of Jaboticabal-SP. A total of 250 samples were collected and used to determine the number of sporulated bacteria from Clostridium genderand identify the pathogenic species present. The results demonstrated that the average number of CFU in log 10 of Closrtidium sp was 2,79, and the minimum and maximum values obtained were 2,15 and 3,68 respectively. After characterization and isolation and identification, the results showed the presence of 233 samples (93,2%) of sporulated bacteria, of these 180 were of Clostridium gender. The biochemical tests were identified in 42 samples, being 23 samples (9,2%) of Clostridium perfringens, 13 samples (5,2%) of Clostridium botulinum and 6 samples (2,4%) of C. chauvoei ...(Complete abstract, click electronic access below)
