“Antibiotic Resistance in the Vibrio species isolated from the estuarine sediments of Uttara Kannada Karnataka”

Abstract

Vibrio species are the marine pathogenic bacterium which causes the health issues in the infected organisms. Antibiotic resistance in the Vibrio species is the threat to the human health by the transfer of the resistant gene in the human from the food chain. The present study was carried out to isolate the Vibrio species and to study antibiotic resistance from the sediments of two estuaries Kali and Aghanashini from Uttara Kannada, Karnataka. The sampling was done during low tide for the period of ten months from September 2021 to June 2022. The total vibrio count was observed in range between 3.86 to 4.83 Log X10¹ CFU/g. Vibrio parahaemolyticus, Vibrio alginolyticus, Vibrio navarrensis and Vibrio vulnificus were isolated and identified from the sediments. The identified Vibrio species were resistant to ampicillin and sensitive to chloramphenicol and tetracycline. Due the over use of antibiotics in the aquaculture and mariculture activities there is a possibility of organism to show multiple resistance towards the antibiotics.
