ampylobacter Jejuni is one of the Gram-negative bacteria causing worldwide foodborne illness, especially from poultry species. Human infection may be raised as a consumption of uncooked infected poultry. This study evaluates the occurrence of Campylobacter jejuni in different commercial poultry species (chickens, ducks, and pigeons) and evaluates its virulence. In this study, different organs were collected and pooled together (liver intestine) from chickens, ducks, and pigeons from different Egyptian provinces. The total isolation percentage for Campylobacter species was 26.4% and the highest percentage was from ducks 36% followed by chickens (25%) and pigeons (22.8%), but the majority of Campylobacter Jejuni was detected in Pigeon samples (75%), followed by chickens (60%) and ducks (33.3%). The existence of cdtA, virB11, and aimA. Virulence genes were present in 81%, 33%, and 43% of the total examined C. jejuni strains. This study provides evidence of different virulence mechanisms that have been hidden in different poultry species.

Objective Campylobacter species are the main causes of foodborne illness worldwide, posing significant threats to public health. This study aimed to investigate the antibiotic resistance and genomic characterization of C. jejuni/C.coli from retail chickens in Beijing. Methods Antimicrobial susceptibility testing was conducted on 126 C. jejuni/C. coli isolated from retail chickens in Beijing, following CLSI protocols. Whole genomes of all isolates were sequenced using the Illumina platform. Results More C. coli (83.82%) showed multi-drug resistance than C. jejuni (8.62%). Genomic analysis demonstrated 42 sequence types (STs) and 12 clonal complexes (CCs), from which CC828 and CC52 were dominant. cdtA, cdtB and cdtC encoding cytotoxic protein were present spontaneously in most C. jejuni but not found in any C. coli isolates. The abundances of antibiotic resistance genes (ARGs) and virulence genes (VGs) in C. jejuni and C. coli were significantly different, with ARGs numbered in C. coli and VGs in C. jejuni. Conclusions High prevalence of multi-drug resistance C. coli and C. jejuni isolated from Beijing chickens were challenging clinical antibiotic usages in the treatment of Campylobacter infection. The surveillance of particular C. jejuni and C. coli STs correlated with higher resistance and virulence needs to be strengthened in the future.
