Resistance of Vibrio sp bacteria in Vaname shrimp (Litopenaeus vannamei) rearing ponds in Jepara to antibiotics amoxicillin and enrofloxacin

Abstract

This study aims to determine the morphological characteristics of Vibrio sp. bacteria, identify the types of Vibrio sp. bacteria present in vannamei shrimp ponds in Jepara, and analyze the resistance of Vibrio sp. bacteria to the antibiotics amoxicillin and enrofloxacin. The method used in this study is exploratory confirmatory. Water and shrimp gut samples were obtained from vannamei shrimp ponds in Jepara, Central Java. The morphological results of Vibrio sp. bacteria showed two colors, green and yellow, circular and irregular shapes, convex and flat elevations, and smooth and undulating edges. Vibrio sp. bacteria found in the water and shrimp gut included Vibrio parahaemolyticus, Vibrio anguillarum, and Vibrio metschnikovii. The analysis of amoxicillin and enrofloxacin antibiotics tested in water and shrimp gut samples fell into the resistant category, indicating that Vibrio parahaemolyticus, Vibrio anguillarum, and Vibrio metschnikovii bacteria were resistant to amoxicillin and enrofloxacin antibiotics.
