Fecal shedding of Campylobacter jejuni and Campylobacter coli among feral pigs in Texas

Abstract

The population and range of feral pigs in the United States are rapidly expanding, yet key knowledge gaps exist regarding their role in the ecology and transmission of foodborne pathogens. Our objectives were to estimate the prevalence of Campylobacter jejuni and Campylobacter coli shedding among feral pigs throughout Texas and to identify risk factors for positive status. Faecal samples were collected from feral pigs in Texas from February 2014 through May 2015, and target organisms were detected using PCR assays. The prevalence of C. jejuni shedding was 1.6% (6/370), and the prevalence of C. coli shedding was 3.5% (13/370). C. coli shedding was significantly more common (p = .008) among female pigs than among male pigs. Feral pigs may represent a source of human campylobacteriosis.

Effect of amoxicillin‐clavulanic acid on clinical scores, intestinal microbiome, and amoxicillin‐resistant Escherichia coli in dogs with uncomplicated acute diarrhea

“…A DI <0 reflects normobiosis, whereas a DI ≥2 dysbiosis, and values between 0 and 2 are considered to be equivocal. The abundances of Clostridium perfringens 16S rRNA gene, C. perfringens enterotoxin gene, C. perfringens NetF gene, C. difficile 16S rRNA gene, and C. jejuni gene in feces were analyzed by qPCR assays using the published oligonucleotide primers and assays 38‐41 . PCR conditions were 95°C for 20 seconds, 40 cycles at 95°C for 5 seconds, and 10 seconds at the optimized annealing temperature.…”

Infection, colonization and shedding of Campylobacter and Salmonella in animals and their contribution to human disease: A review

“…Campylobacter is frequently isolated in clinically healthy animals and, therefore, is considered as normal flora in domestic and nondomestic animals (Cummings et al, 2018;Dong, Cho, Hahn, & Cho, 2014;Mdegela et al, 2011;Sproston et al, 2011). Host factors including species, age and physiological status determine the level of Campylobacter prevalence and shedding in animals.…”

Campylobacter in aquatic and terrestrial mammals is driven by life traits: A systematic review and meta-analysis

“…Interestingly, from our analysis it has demonstrated importance in the carriage of C. coli, with social species more likely to carry this pathogen (Figure 3). A study of C. coli prevalence in feral pigs found a significant difference between males and females, with males more likely to carry the bacteria (Cummings et al, 2018). It was postulated that this was due to the social structure of pigs, as males are more likely to (Gillespie et al, 2002;Roux et al, 2013), which implies that different risk factors could also be associated with C. coli in wildlife.…”
