A study seek to identify the bacterial germs that colonize aquatic environments in relation to some abiotic parameters of the environment was conducted from March to September 2018 in five neighborhoods of Yaounde on 14 wells, 7 sources and 5 streams. The sampling stations were chosen according to the sources of pollution, their geographical distribution, and their importance for the user populations. Samples and physico-chemical and bacteriological analyzes were carried out using appropriate techniques. The physicochemical analyzes revealed that the samples are generally well oxygenated (Dissolved oxygen (8 mg/L)), rich in organic and mineral matter (BOD5 = 41,66 ± 20,5 mg/L of oxygen) and loaded in particles (Total dissolved solids = 121,04 ±94,4 mg/L, Suspended Solids = 30, 67 ± 22,0 mg/L). The results of the bacteriological analyzes show that these waters host many bacterial communities such as total coliforms and fecal coliforms with a frequency of occurrence at more than 40% of species such as Escherichia coli, Serratia marcescens, Klebsiella oxytoca, Klebsiella pneumoniae, Providencia rettgeri, Alcaligenes denitrificans, Providencia stuartii, Enterobacter gergoviae, Enterobacter cloacae, Pseudomonas aeruginosa. Pseudomonas fluorescens and Citrobacter koseri, all gram-negative bacteria. The densities of these pathogens are significantly related to suspended solids, BOD5, nitrite and orthophosphate levels, and the availability of dissolved oxygen (P <0.05). The origin of faecal pollution in the water points studied varies according to the sites and would be either human, animal or mixed. The dynamics of the abundances of the different germs identified and their occurrence in the environment would be related to the physicochemical quality of the water.
