Studies on Ribotyping, Integron Genes and Pathogenicity of Marine Vibrios

A rare horizontal gene transfer event could be traced. The movement of the SXT element among the Vibrionaceae could be followed. This element was first reported from Vibrio cholerae and in this study the same could be confirmed in Vibrio alginolyticus. Events such as these, which take place with respect to other virulence/virulence associated genes, may lead to the emergence of pathogenic strains from hitherto non-pathogens or may even give rise to new pathogens. The results generated in the course of this study paves way for further characterization and detailed study, especially with respect to those strains which showed gastric fluid accumulation in the in vivo suckling mouse assay. Antibiotic resistance pattern shown by a sample population of Vibrios can be used for deciding treatment options. There is enough scope for further research on these topics towards generating basic knowledge, which can be of immense significance in human and aquaculture health.
