The Nyong, which is the second longest river in Cameroon, plays a major role in national economy. This prospective study aimed to contribute to the protection of aquatic ecosystems. The specific objectives were to assess bacteriological quality of the Nyong River water and the impact of its use on riverside population’s health. Water samples collected from January to March 2012 were submitted for bacteriological analysis. A questionnaire survey was also administered to riparian communities. Numerous bacterial strains belonging to various species, including 14 of the Enterobacteriaceae family have been isolated, in a spatial and temporal diversity. Enterobacter cloacae was the most frequent and abundant specie. Escherichia coli was isolated at less accessible stations, with fishing and recreational activities. All the respondents to the questionnaire used the Nyong River water for plant watering, bathing, drinking, cooking, laundry, fishing or to do the washing up. The complaints reported were itching, non-febrile gastroenteritis, febrile gastroenteritis, urinary tract infections and typhoid fever. The Nyong River water was not recommended for drinking purpose. It was found to be of good quality for bathing (class A) and for the production of water for human consumption (class A1). Following its characteristics, a relationship could be established between the complaints of urinary tract infections and febrile or non-febrile gastroenteritis expressed by some residents
