Vibrio alginolyticus, Antibiotic, Resistance, Bla TEM, Bla CTX-M, Gyra, Bla VIM


Vibrio alginolyticus is a halophilic Gram-negative pathogenic bacterium. It is considered as one of the most frequent species living freely in water and sediment and can survive in sea water even in famine conditions while maintaining their virulence. Gram-negative bacteria are highly efficient in up-regulating or acquiring genes that code for mechanisms of antibiotic resistance, especially in the presence of antibiotic selection pressure. Furthermore, they have available to them a plethora of resistance mechanisms, often using multiple mechanisms against the same antibiotic or using a single mechanism to affect multiple antibiotics. This study began with the observation of multi-resistant Vibrio alginolyticus strain recovered from the coastal sediment of Tuticorin beach. The aim of this study was to determine the prevalence of some important resistance genes encoding bla TEM, bla CTX-M, gyrA and bla VIM in the test isolate i. e. Vibrio alginolyticus strain PTS13.
