Resumo: |
Considering the illnesses are barriers for the development of the carcinicultura, the vibriose has the possibility to occur for having as etiologic agent bacteria autochtonous of marine environment, it was objectified identification of the interferentes factors in the frequency of this disease. Four situated farms in the south coast of Pernambuco had been selected of which samples of water and shrimp during all had been collected monthly the phases of culture in two different climatic cycles (wet and rainy). Esteem the load of Vibrio spp., samples of water, post larvae had been analyzed, hemolymph and hepatopancreas and the countings had been correlated, through the use of mathematical models (P<0,05), with the variable - physical and chemical of the water, season, microscopical observation, histopathology, presence of toxins and production management methods. With it was observed that only the changeable time of culture intervened with the total counting of Vibrio spp. The counts varying from 0 to 2,9 x 104 in the water, from 0 to 2,1 x 105 in post larvae, from 0,1 x 10 to 1,1 x 105 in hemolymph and from 7,0 x 10 to 1,1 x 106UFC/mL/g in the hepatopancreas. The load of vibrionáceos increases with cycle duration, and it does not suffer influence from the variable physical and chemical of the water, of the handling, of the toxin presence. |
