No. of bitstreams: 1 Cassia Aldrin de Mello.pdf: 4250938 bytes, checksum: 88a7fbf54f3c43c0895924fbf26b6c5d (MD5) Previous issue date: 2008-02-14 / Cuiabá river basin, in Mato Grosso State is one of means river receivers of domestic sewage and industries effluents, for them, fishes captured can become contaminated and to be a dangerous to consumer, being rasing of fishes capitivity a viable alternative to provide better quality fish. Specimes of Brycon microleps (piraputanga) captured both from the captivity and from the river on region were studied microbiologically about the mesophiles, total and termtolerants coliforms, Aeromonas and Salmonella, on rain season, and dry season. About specimes were collected liver and encephalo, and to the comparation of values were used the test of correlation of Spearman and the Kolmogorov-Smirnov test. It was verified the sazonality effect (month of collection) over the counting of mesophile, termtolerants coliforms and Aeromonas, at both fish obtained from captivity and river. Higer contamination were observed in finish of dry season and all dry season, then, at most months hots, between August and March. The isolates were A. hydrophila and A. caviae from captivity fishes and A. sobria and A. hydrophila from river fishes, and a relationship was observed between the Aeromonas total number and the coliforms level, in other words, as higher the level of coliforms in sample, higher they were the Aeromonas spp. countings, being the high countings and the low or null, verified in the same months. Salmonella spp. was isolated at one river sample and one of captivity sample. Escherichia coli was isolated in both the fishes, of indicative that some way the water of the two atmospheres was polluted with feces. It was verified that the probability of contamination by mesophiles occurrence in river collected fish is the same as captivity ones (P 0,05). / A bacia do rio Cuiabá no estado de Mato Grosso é uma das principais receptoras de esgotos domésticos e industriais e por isto, os peixes nela capturados podem estar contaminados e representar perigo ao consumidor, sendo a criação de peixes em cativeiro uma alternativa para a obtenção de peixes microbiologicamente melhor. Exemplares de Brycon microleps (piraputanga) oriundos do rio Cuiabá e de cultivo na região foram analisados quanto à bactérias mesófilas, coliformes, Aeromonas e Salmonella, nos meses de chuva e seca. Dos exemplares foram utilizados fígado e encéfalo, e para a comparação dos dados utilizou-se a correlação de Spearman e o teste de Kolmogorov-Smirnov. Verificou-se o efeito da sazonalidade (mês de coleta) sobre a contagem de bactérias mesófilas, coliformes termotolerantes e Aeromonas, tanto em peixes capturados no rio como nos cultivados, sendo as maiores contagens observadas no final do período seco e no início do período chuvoso, ou seja, nos meses mais quentes do ano, entre agosto e março. Foram isoladas A. hydrophila e A. caviae dos peixes de viveiro e A. sobria e A. hydrophila dos peixes do rio e observou-se uma relação entre a contagem de Aeromonas e coliformes, ou seja, quanto maior a contagem de coliformes da amostra maiores foram as contagens de Aeromonas. A Salmonella spp. foi isolada de uma amostra de rio e uma de viveiro. Escherichia coli foi isolada nos peixes de rio e de viveiro, indicando que a água dos ambientes estava contaminada com fezes. Verificou-se que a probabilidade de ocorrência da contaminação por mesófilos em peixes capturados no rio, é a mesma nos obtidos em cultivo (P 0,05).
