Abstract: 
In order to identify and count parasites in poultry drinking water (Gallus gallus domesticus) which contains six (06) varieties in Cameroon. This study takes place in the city of Yaoundé more precisely in four stations (Nkoabang farm, Ngousso farm, Ekounou market and Mfoundi market), during the long dry season to the short rainy season of the year 2023. Physico-chemical analyzes were carried out in the field and in the laboratory. The observation of oocysts was made under the IVYMEN microscope with the 40X objective and the 100 objective using immersion oil and the formalin-ether concentration method and the modified Zielh-Neelsen method allowed us to isolate the oocysts. Biological analyzes show that the species of Cryptosporidium spp. was the highest (243 ± 212 oocysts/L) for the Ekounou market station and (199 ± 186 oocysts/L) for the Mfoundi market. The highest protozoan densities were recorded during the short rainy season (PSP). The least dense species was Isospora spp. with (11 ± 24 oocysts/L) at the Mfoundi market and (1 ± 1 oocysts/L) at the Ekounou market. The presence of these pathogens shows that these drinking waters need more strict and intense monitoring for animal and human health. The physicochemical results present high values of turbidity, color, total dissolved solids and very low dissolved oxygen value of up to 2%. The nitrate values vary from 0,15 mg/L to 13 mg/L as well as the temperature values which vary from 22,2°C to 27,1°C.
