Identification of Vibrio spp bacteria on skin lesions of fisherman in the county of Raposa-MA

The study was undertaken aiming at identifying bacteria from the county of Raposa in the state of Maranhão. The clinical sample was collected by using a swab and held in a Cary-Blair transport medium. Enrichment in alkaline peptone water, isolation in TCBS selective indicator medium and biochemical coding of species were used for laboratory processing. Fifty fisherman with age varying from 12-65 years took part on the study. Vibrio bacteria isolated in 21 subjects had been identified. There was a predominance of V. alginolyticus (66.6%) followed by V. parahaemolyticus (42.8%), and V. cholerae non-O1 (9.5%). Lesions predominated on lower limbs, presenting hyperhemia, swelling, secretion, and pain. Some species of gram-negative bacteria of the Serratia, Proteus, Escherichia, Citrobacter, Enterobacter associated to the vibrios were isolated, as well as other non-fermenting bacteria (30.9) and gram-positive bacteria of the genos Staphylococcus.
