Resumo: |
The Infectious Myonecrosis Viral (IMNV), restricted action to the Brazilian northeast up to 2006, is disease of bigger negative impact in the shrimp cultured of the region. Having the objective to verify occurrence and evolution of the IMNV in Litopenaeus vannamei cultured on the coast of Pernambuco, Brazil, histopathological examination in 60 samples of shrimps from four farms in two cycles of aquaculture was proceeded. The histopatological findings had been correlated the data of the wet mount and the inquiry. Suggestive injuries of IMNV (coagulation necrosis, muscular hemocitic infiltration, spheroid of the ectopic lynphoid organ) were found in samples of the four studied farms with bigger occurrences in the first cycle. However, in the rainy period it had reduction of the occurrence, being associated the handling change. The raise time and the density were variables which influenced significantly (P<0,05) in the manifestation of the IMNV. |
