Isolation and characterization of Aeromonas species from an eutrophic tropical estuary.
Isolation and characterization of Aeromonas species were undertaken in the Ebrié lagoon (Abidjan, Côte d'Ivoire) over a one year period. Overall 63% of 501 water samples were identified as positive for Aeromonas spp. A. sobria, A. hydrophila and A. caviae represent respectively 49.20%, 20.63% and 30.15% of the positive samples. Thirty nine of the positive samples were recovered from surface water samples; while 24 bottom water samples were positive for Aeromonas. Aeromonas species are most frequently (82.53) present in the Ebrié lagoon urban area during the rainy and flood seasons when the salinity is low and below 10 per thousand. A lower isolation frequency is noticed during the dry season when water salinity is over 10 per thousand. Finally, a higher isolation frequency occurred in samples with highest counts of Escherichia coli.
