Antimicrobial Resistance Profiles, Virulence Genes, and Genetic Diversity of Thermophilic Campylobacter Species Isolated From a Layer Poultry Farm in Korea

Abstract: Thermophilic Campylobacter species are among the major etiologies of bacterial enteritis globally. This study aimed at assessing the antimicrobial resistance (AMR) profiles, virulence genes, and genetic diversity of thermophilic Campylobacter species isolated from a layer poultry farm in South Korea. One hundred fifty-three chicken feces were collected from two layer poultry farms in Gangneung, South Korea. The Campylobacter species were isolated by cultural techniques, while PCR and sequencing were used for s… Show more

“…Regarding invasion abilities, the authors' previous studies have revealed the common prevalence of ciaB (83.3%) and pldA (70%) genes among wildlife waterfowl, regardless of the source. The high prevalence of these genes was previously noted in wild bird isolates [37], layer poultry isolates [41], chicken meat isolates [42], and in human and cattle isolates [43]. The overall prevalence rates of two other tested virulence genes associated with invasion (virB11 and iam) were 26.7% and 6.7%, respectively.…”

“…Increasing rates of Campylobacter strains resistant to the drugs of choice and alternative therapies, making AMR Campylobacter a public health concern ( Mourkas et al, 2019 ; Gahamanyi et al, 2021 ), and MDR is still very common in Campylobacter strains isolated from farmed animals in many European countries ( Pascoe et al, 2017 ). In this study, MDR was common in C. jejuni HS19 isolates from cattle, indicating a potential hazard.…”

“…The genetic diversity of the pathogenic factors of Campylobacter is an important cause of differing pathogenicity ( 17 ). Much research has been invested to identify species-unique genes of Campylobacter and genes of different pathogenicity ( 18 , 19 ). With the application of whole-genome sequencing technologies, diverse Campylobacter species have been sequenced in recent years ( 20 , 21 ).…”
