Abstract:

Introduction: Vibrio cholerae is a human pathogen and natural inhabitant of aquatic environments. In this study we surveyed
the occurrence of V. cholerae in fish harvested from a reservoir Barrage de Tanghin in Ouagadougou, water of which is
increasingly used for fishing and for irrigation of vegetables. The water is of poor quality, because several channels convey
municipality’s discharges directly to the reservoir.
Methodology: A total of 238 fish (Oreochromis niloticus), 25 samples of reservoir water and 55 samples of channel water were
analyzed for the presence of V. cholerae.
Results: Altogether, 13 V. cholerae strains were isolated from the fish (from 5% of the samples), 1 (4%) from the reservoir water
and 4 (7%) from the channel water. All the strains were identified as non-O1/non-O139 V. cholerae and they did not possess the
Cholera Toxin–encoding ctxA gene. The antimicrobial susceptibility testing showed that the strains were in general susceptible
but approximately half of them were resistant to ampicillin.
Conclusion: Although no strains of epidemic V. cholerae serotypes were encountered, it would be important to monitor the
microbiological quality of this extensively used water resource and its products for vibrios as well as for other enteropathogenic
bacteria.
