Vibrio bacteria research studies

The city of São Luís, capital of Maranhão state (Brazil), provides ineffective treatment of its effluents, which are released straight into the water resources. In order to search for indicators of fecal contamination at the coastal environment we collected samples from different sites. Samples from Ponta d'Areia, São Marcos, Calhau and Olho d'Água beaches were analyzed aiming to detect pathogens and diarrheagenic strains of Escherichia coli; in addition to test the susceptibility of diarrheagenic E. coli strains to sanitizer agents. In all analyzed areas, species of E. coli, Serratia liquefaciens, Hafnia alvei, Salmonella spp., and Serratia sp were identified. Strainsof diarrheagenic E. coli were identified thorough the Polymerase Chain Reaction (PCR), 82% corresponded to enterotoxigenic E. coli (ETEC), 9% to enterohaemorrhagic E. coli (EHEC) and 9% to enteroaggregative E. coli (EAEC). The sanitizers tested were detergent, domestic alcohol and sodium hypochlorite, the latter presented higher bactericidal effect for all E. coli strains. The study showed that the local sanitation problems contributed to the contamination of the beaches in SãoLuís by microorganisms resistant to sanitizers which pose risks to public health.
