Abstract:

In the present study, six species of Vibrio that are potential human pathogens have been isolated from surface water resources in an urban environment and have been identified. The variation of some physico-chemical factors known to have significant effects on bacterial growth and spread are also considered. The latter include: electrical conductivity, pH, total suspended solids, temperature, dissolved oxygen and carbon dioxide, and rate of water flow. All investigations were conducted according to standard methods. Application of classical bacteriological techniques led to the identification of six species of the genus. Vibrio cholera, Vibrio fluvialis, Vibrio mimicus, Vibrio alginolyticus, Vibrio parahaemolyticus and Vibrio vulnificus. Vibrio cholerae was isolated in all water sampling points, with the highest frequency 79% upstream the Mfoundi River at Etoa-Meki. Rates of isolation of Vibrio mimicus increased with increased O2 (p<0.05). Identification of these potential pathogens is a serious public health hazard highlighting the needs for resource management.
