Vibrio spp. como patógenos na carcinicultura: alternativas de controle

Abstract

Shrimp farming, an important agribusiness activity worldwide, experiences significant losses due to diseases. Among the pathogenic agents, bacteria of the Vibrio genus are prominent for the high mortality rate registered in infections. Antibiotics are the most frequent option in to fight such diseases, however, their careless use increase the selective pressure on resistant bacterial strains in aquatic environment, which results in risks for the environment and for the health of animal and man. As a measure to prevent economic losses, new technologies are being developed in order to fight the emergence of diseases in the environments where aquatic organisms are farmed. Efforts have been directed towards the understanding of infection processes and invasion routes of vibrio strains in farmed shrimp, as to develop better control techniques against pathogens. Biosafety procedures in farms must integrate concepts of health, nutrition, genetics and environmental quality for an effective control of diseases. In this review, we aim to delineate a profile of the shrimp farming scenery and vibriosis control.
