ABSTRACT: Microbial resistance to antibiotics is a global problem that threatens the lives of millions of people and affects several sectors, including aquaculture. The aim of the present study is to contribute to the monitoring of multi-resistant enterobacterial strains circulating in fish ponds in the Sud-Comoé region of south-eastern Côte d’Ivoire, more specifically in the Aboisso and Tiapoum departments. To this end, 20 samples of Tilapia fish (Oreochromis niloticus) and 60 samples of farm water were collected from 5 fish farms in the Sud-Comoé region. Microbiological analyses were based on the isolation and identification of enterobacteria on Mac Conkey + Ceftazidime medium. These analyses resulted in the isolation of 73 strains of enterobacteria, including 58 from fish and 15 from fish pond water samples. Antibiotic sensitivity tests carried out on enterobacteria isolated from water and fish samples showed high levels of resistance (100%) to the beta-lactam family (Amoxicilin + clavulanic acid, Ceftazidime). Klebsiella pneumoniae and Enterobacter spp. showed resistance to Ciprofloxacins (100%) and (25%) respectively. The study also showed that strains of Enterobacteriaceae were resistant to all 3 families of antibiotics, notably Beta-lactams, Fluoro-quinolones and Aminosides. The presence of multi-resistant Enterobacteriaceae in fish and pond water samples represents a public health risk.
