            Abstract

            The objective of this study was to establish the antibacterial resistance profile of vibrio strains isolated from  the hemolynph, hepatopancreas and muscle of Pacific white shrimp,  Litopenaeus vannamei , collected from farms in  Northeastern Brazil. Nine (43%) out of 21 strains presented a multiple antibiotic resistance (MAR) index of ≥0.2,  indicating an overall pattern of multiresistance. MAR values were higher for strains from hemolynph (0.19), followed  by strains from hepatopancreas (0.143) and muscle (0.095). The highest MAR values observed (0.62) came from two  strains (one hemolynph, one hepatopancreas) resistant to six classes of antibiotics. Two strains isolated from muscle  were resistant to five classes of antibiotics. In conclusion, the emergence of multiresistant strains in the microbiota of  shrimp reared on farms in Northeastern Brazil may be the added effect of extensive use of antibiotics by aquafarmers and  contaminated discharge from neighboring hospitals, sewers, crops and livestock.
