摘　　要：Enteric campylobacteriosis caused by <i>Campylobacter</i> 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 <i>Campylobacter</i> as the first germ responsible for gastroenteritis in developing countries. The objective of the study is to determine the prevalence of <i>Campylobacter</i> 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, <i>Campylobacter</i> 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 <i>C. coli</i> (52.77%), <i>C. jejuni</i> spp. <i>jejuni</i> 1 <i>and</i> 2 (30.58%), <i>C. festus</i> spp. <i>festus</i> (11.11%), <i>C. jejuni</i> spp. <i>doley</i> (1.38%), and <i>Campylobacter</i> spp. (4.16%). Bacterial enumeration gave <i>Campylobacter</i> 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 <i>Campybacter</i> cases, followed by the 8^th market and Essos market. From the above, it is important to notice that the <i>Campylobacter</i> danger remains and that preventive measures are of great interest.Enteric campylobacteriosis caused by <i>Campylobacter</i> is a real public health problem.
