Prevalence and risk factors of Campylobacter infection in goats in southern provinces of Thailand.

Abstract

Campylobacter is a foodborne pathogen that could be isolated from various types of livestock, including small ruminant. The objectives of the current study were to investigate the prevalence of Campylobacter spp. in goats reared in the south of Thailand and identify the risk factors associated with Campylobacter infection of goat in Thailand. A total of 600 rectal swabs of goats from 45 farms in 6 provinces of Southern Thailand were collected during 2016-2020. To analyse the risk factors associated with Campylobacter infection in goat, data collection was conducted via structured questionnaires. Campylobacter isolation was performed by direct plating on modified charcoal cefoperazone deoxycholate agar (mCCDA). Polymerase chain reaction (PCR) was used to identify genus and species of the isolates. In total, 68 out of 600 rectal swab samples (11.33%; 95% CI 8.96 to 14.21%) collected from goats were positive for Campylobacter. The prevalence of Campylobacter spp. in the province level ranged from 0 to 31.48%. Interestingly, Campylobacter lanienae was the dominant species, followed by Campylobacter coli and Campylobacter jejuni. To investigate the risk factors associated with Campylobacter infection in goats, farm management factors, i.e. deworming, fencing around the house, housing design, number of animals on farm, use of antibiotics and vaccination, were included in logistic regression analysis. Statistical analysis revealed that the use of antibiotics and deworming were associated with Campylobacter infections in goats. The current study emphasises that the prudent use of antimicrobials and good agricultural practices should be applied in goat farming.
