Genetic insights into antimicrobial resistance and virulence characteristics of Salmonella enterica isolated from Nile tilapia sourced from retail markets in Thailand.

ABSTRACT:

Background

Antimicrobial-resistant Salmonella enterica in aquaculture represents a significant public health concern due to its potential transmission through the food chain. Despite these concerns, there is a notable lack of comprehensive genomic characterization of S. enterica isolates from Nile tilapia in Thailand. This study aimed to evaluate the prevalence, antimicrobial resistance (AMR) profiles, and genetic diversity of S. enterica isolated from retail-sourced Nile tilapia (Oreochromis niloticus) between May and October 2023.

Methods

A total of 714 Nile tilapia specimens comprising liver, kidney, meat, gill, mucus, lung, and intestine tissues were collected from fish purchased at retail markets in Thailand. Salmonella isolation and identification were performed using
