Diversity and antimicrobial resistance among bacterial isolates from finfish aquaculture in Thailand.

ABSTRACT:

Background

Global aquaculture, has expanded rapidly, especially in Southeast Asia, with Thailand emerging as a leading producer. However, the sector faces economic losses from disease outbreaks and has problems with escalating antimicrobial resistance (AMR).

Results

This study examined bacterial diversity and AMR in 695 moribund fish samples collected from regions across Thailand between 2018 and 2024, and spanning eight key finfish aquaculture species such as tilapia, Asian sea bass, snakeskin gourami, snakehead, walking catfish and carp species. Gram-negative bacteria (86.62% of isolates) were dominated by Vibrionaceae and Aeromonadaceae, while Gram-positive bacteria were primarily from Streptococcaceae, with notable species including A. veronii, V. vulnificus, S. agalacti
