Enterobacteria and Vibrio from Macrobrachium amazonicum prawn farming in Fortaleza, Ceará, Brazil

摘要: Abstract Objective To investigate the isolation of enterobacteria associated with Macrobrachium amazonicum ( M. amazonicum ) farming and evaluate in vitro antimicrobial susceptibility Vibrio strains. Methods Strains were isolated from female prawns environmental hatchery water. Biochemical assays used to identify bacterial genera those belonging genus submitted further analyses for species identification, through Vitek 2 automated system serotyping. Susceptibility test was performed according Clinical Laboratory Standards Institute. Results The following recovered: Enterobacter n  = 11), Citrobacter  = 10), Proteus  = 2), Serratia Kluyvera Providencia Cedecea  = 1), Escherichia Edwardsiella  = 1) Buttiauxella  = 1). As , three identified: cholerae non-O1/non-O139  = 4), vulnificus (V. vulnificus) mimicus spp. showed minimum inhibitory concentrations values within range established by Institute almost all antibiotics, except V. vulnificus which presented intermediate profile ampicillin. Conclusions Enterobacteria do not seem be most important pathogens farming, whereas recovery larviculture, emphasis on deserves special attention due their role as potentially zoonotic aquaculture-associated pathogens. Furthermore, ampicillin reflects importance monitoring drug use in prawn farming.
