The presence of Vibrio spp. and Salmonella spp. in crabs marketed at the Bezerra de Menezes Ave., Fortaleza, State of Ceará, Brazil, was assessed between February and May, 2003. The number of individuals sampled in each one of the fifteen weekly samplings ranged between four and eight. Seven strains of Salmonella, from four different samplings, were identified, being five of them identified as serotype S. Senftenberg and two as S. Poona. All strains of Salmonella were sensitive to the tested anti-microbial drugs, with the exception of tetracycline and nalidixic acid, for which an intermediary sensibility was found. The MPN's for Vibrio ranged between 110/g and 110,000/g. Of the forty five Vibrio strains isolated from the crab samples, only 10 were identified up to the species level: two V. alginolyticus and eight V. parahaemolyticus. Bacteria belonging to the Enterobacteriaceae and Pseudomonaceae families were also identified, namely Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae, Pantoea agglomerans and Pseudomonas aeruginosa. The proper cooking of the animals is recommended in order to avoid problems for the consumers of this crustacean. Foram pesquisadas a presença de Vibrio spp. e de Salmonella spp. em caranguejos comercializados na Av. Bezerra de Menezes, Fortaleza, Ceará, Brasil, no período entre fevereiro e maio de 2003. O número de indivíduos em cada, das quinze coletas realizadas, semanalmente, variava entre quatro e oito dependendo do tamanho dos animais, totalizando um número de 90 (noventa) animais examinados. Foram identificadas sete cepas de Salmonella spp. provenientes de quatro coletas: cinco foram identificadas como sorovar S. Senftenberg e duas como S. Poona. Todas as cepas de Salmonella, isoladas das amostras de caranguejos, apresentaram sensibilidade aos antimicrobianos testados, com exceção de tetraciclina e ácido nalidíxico para os quais elas apresentaram uma sensibilidade intermediária. Os NMPs para Vibrio spp. variaram entre 110 e 110.000/g. Das quarenta e cinco cepas de ...
