Observational analysis revealed a link between bacterial pathogens and summer mortality in Nile tilapia, suggesting antimicrobial resistance is a growing concern.
Key Points
Mortalities in farmed Nile tilapia were significantly associated with various bacterial pathogens and their antibiotic resistance profiles.
Thirty bacterial isolates were identified, with 57% classified as Gram-positive and 43% as Gram-negative organisms.
Genome sequencing confirmed key pathogens including Aeromonas veronii and Enterococcus faecalis, showing varied antibiotic resistance patterns.
The emergence of resistance to multiple antibiotics underscores the need for improved management practices in aquaculture settings.
