Resumo: |
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). |
