Microbiological characterization of pathogenic Vibrio-like bacteria in the native species Guanchiche (Hoplias malabaricus) in the Vinces River, Ecuador

Abstract:

The study demonstrates whether the Guanchiche of the Vinces rivers presents pathogenic bacteria of the Vibrio type, which can cause many gastrointestinal diseases. The fish were obtained directly from the sampling sites, and the physiological and nutritional status of the fish was determined through the indicators Hepatosomatic Index (IHS), Gonadosomatic Index (IGS), Condition Factor (CF), and microbiological isolation and characterization. Values referring to total length (TL) 31.48±1.08 and weight 322.86±23.65 as well as biological indexes such as IHS 1.23±0.13; IGS of 6.28±1.11 and FC of 1.08±0.11 were found. Microbiologically, two Vibrio-type strains were isolated in a selective medium corresponding to Vibrio Cholerae and Vibrio parahaemolyticus; this research work is important to prevent the population from the presence of bacteria that can endanger human health.
