Enteric campylobacteriosis caused by Campylobacter is a real public health problem. It is a typical zoonosis that can be transmitted through direct contact with contaminated animals or animal carcasses, or indirectly through the ingestion of contaminated food or water. WHO¹ defines Campylobacter as the first germ responsible for gastroenteritis in developing countries. The objective of the study is to determine the prevalence of Campylobacter in pigs and to identify the most common species found in three slaughterhouses in the city of Yaounde. A descriptive and prospective study was carried out over a period of five months, from July to November 2020. To do this, Campylobacter spp. strains were searched for by culture on specific media, incubated in a micro-aerophilic atmosphere at 37°C and the identification with API campy (BioMérieux, ref 20800). Out of the 266 samples collected, 170 from the rectum and 96 from the carcasses, we obtained a general prevalence of 27%, with a prevalence of 25.88% in the rectum and 29.16% in the carcasses. Pigs intended for consumption by the population of Yaounde come mainly from the North (50%) and the West (49%). The most common species encountered were C. coli (52.77%), C. jejuni spp. jejuni 1 and 2 (30.58%), C. festus spp. festus (11.11%), C. jejuni spp. doley (1.38%), and Campylobacter spp. (4.16%). Bacterial enumeration gave Campylobacter fecal concentrations at 10³ CFU² (52.7%), 10⁴ CFU (33.3%), and 10⁵ CFU (13.8%). The slaughterhouse in the Mvog Ada market was the most involved in Campybacter cases, followed by the 8^th market and Essos market. From the above, it is important to notice that the Campylobacter danger remains and that preventive measures are of great interest.
