Phenotyping of vibrios isolated from marine shrimp hemolymph

Abstract

The phenotypic characterization of 100 Vibrio strains isolated from the hemolymph of cultured Pacific white shrimp, Litopenaeus vannamei, was performed. This process allowed the identification of 10 species: V. navarrensis (n = 53), V. brasiliensis (n = 15), V. parahaemolyticus (n = 10), V. xuii (n = 8), V. cholerae (n = 5), V. coralliilyticus (n = 4), V. neptunis (n = 2), V. alginolyticus (n = 1), V. diazotrophicus (n = 1), and V. vulnificus B3 (n = 1). These results suggest that penaeid hemolymph may be colonized by vibrios with no imposition or necessity of pathological compromising.
