- Abstract: Thermotolerant Campylobacter genus is one of the most prevalent causes of gastroenteritis in humans, especially C. coli and C. jejuni. Despite the importance of Campylobacter diagnosis to public health, many laboratories continue to adopt the slow, inaccurate conventional culturing approach, which leads to false-negative/positive results. The origin, transmission, pathogenicity, and pathophysiology of Campylobacter spp. diseases are poorly understood. Therefore, in this study, the samples were collected over a period from August 2021 to September 2022; about 100 poultry samples and 43 stool specimens from children were collected. According to conventional culturing techniques, the overall prevalence of the Campylobacter genus in both poultry and humans was determined to be 31.5%, whereas PCR analysis of poultry (30) and human specimens (43) for Campylobacter genus revealed a 35.6% isolation rate. While C. coli was the only species detected in poultry-positive Campylobacter genus samples demonstrated by 27.3%, the human-positive Campylobacter's isolates were C. coli with 33.3%, C. jejuni and mixed infection with 6.7%. Shannon and Simpson biodiversity indexes quantify genetic diversity; assuming that Campylobacter species express virulence genes differently, we found that C. coli had a higher Shannon diversity index (0.8487) and Simpson index (0.4938), while C. jejuni had (0.6931) for Shannon and (0.5) for Simpson index. Regarding host-virulence genes diversity, human-derived strains had a higher Shannon diversity index (1.474) and Simpson index (0.75) than poultry. This study provided evidence that the genetic profiles of circulating species of Campylobacter differ depending on the origin, highlighting the need for genetic diversity knowledge for effective management and prevention strategies.
