Pesquisa de bactérias do gênero Vibrio em feridas cutâneas de pescadores do município de Raposa-MA

Abstract

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.

Avaliação de parâmetros físicos e químicos e pesquisa de Vibrio parahaemolyticus em águas do estuário do rio Anil (São Luís, Estado do Maranhão)

“…No Brasil, tem-se verificado sua ocorrência em moluscos (Leitão e Arina, 1976;Gelli et al, 1979;Zebral, 1988;Sousa, 1989;Archer e Moretto, 1994;Lira et al, 2001;Pereira, 2001), caranguejo e água (Sousa, 1989), fezes (Hofer, 1983;Magalhães et al, 1991), lagostas (Vieira e Iaria, 1993) e feridas cutâneas (Rodrigues, 2001).…”

Enzymatic characterization of Vibrio alginolyticus strains isolated from bivalves harvested at Venice Lagoon (Italy) and Guanabara Bay (Brazil)

“…The inability of some species, like the V. fluvialis, to degrade the components of the conjunctive tissue seems to limit its capacity to cause extra intestinal pathology. The concomitant lack of the keratinases in the majority of Vibrio species, and the ability to degrade the conjunctive tissue is consistent with their condition of opportunists' bacteria which need a primary lesion to invade the derma and hypodermic layers of the skin 3,5,10,11 .…”

“…Otherwise, many species are able to transmit intestinal or extra intestinal diseases to human. Amongst these last ones V. vulnificus, V. carchariae and V. alginolyticus are widely spread in the marine environment; both in closed seas, like the Mediterranean, and in oceans 5,10,11 .…”

“…no ecossistema aquático, lesões cutâneas em pescadores e a partir de alimentos de origem marinha (pescados) caracterizando seu envolvimento em casos de doenças de transmissão alimentar (DTA). Profissionais do ramo da pesca, mergulhadores e manipuladores de alimentos representam grupo de risco nas infecções causadas por vibriões (Rodrigues et al 1992, Rodrigues et al 2001, Pereira 2003. Alguns destes microrganismos são considerados oportunistas e em hospedeiros saudáveis podem fazer parte da microbiota de animais aquáticos, inclusive aqueles criados em condição de cativeiro ou sistemas de aqüicultura.…”
