This review summarizes the epidemiology and antibiotic resistance data of Campylobacter species isolated from humans and food-producing animals in West Africa. The study found a high prevalence of Campylobacter species in both humans and animals, with a higher rate of antibiotic resistance in human samples. Improved farm hygiene and surveillance systems are needed to reduce transmission.
Campylobacter species are one of the leading causes of gastroenteritis in humans. This review reports on the prevalence and antibiotic resistance data of Campylobacter spp. isolated from humans and food-producing animals in West Africa. A systematic search was carried out in five databases for original articles published between January 2000 and July 2021. Among 791 studies found, 38 original articles from seven (41%) out of the 17 countries in West Africa met the inclusion criteria. For studies conducted in food-producing animals, the overall pooled prevalence of Campylobacter spp. was 34% (95% CI: 25-45). The MDR prevalence was 59% (95% CI: 29-84) and half (50%, 13/26) of the animal studies had samples collected from the market. The human studies recorded a lower pooled prevalence of Campylobacter spp. (10%, 95% CI: 6-17), but a considerably higher rate of MDR prevalence (91%; 95% CI: 67-98). The majority (85%, 11/13) of the human studies took place in a hospital. Campylobacter jejuni and Campylobacter coli were the most common species isolated from both animals and humans. Our findings suggest that Campylobacter spp. is highly prevalent in West Africa. Therefore, improved farm hygiene and 'One Health' surveillance systems are needed to reduce transmission.
