Prevalence of Campylobacter and antibiotic susceptibility from broilers in Dong Nai province

Abstract

This study aimed to determine the prevalence and antibiotic susceptibility of Campylobacter isolated from the broilers in Dong Nai province from 9/2020 to 12/2023. The studied result showed that out of 392 collected samples (102 samples of rectal swab and 290 samples of chicken meat), there were 82 samples positive with Campylobacter, accounting for 20.92%. Species identification was performed by multiplex PCR (mPCR), as a result the rate of C. coli species and C. jejuni species was 69.51% and 30.49%, respectively. Antibiotic resistance testing of Campylobacter isolates was performed by disc diffusion method and determining the minimal inhibitory concentration (MIC). The tested result indicated that the isolated Campylobacter strains were resistant to most tested antibiotics with more than 50% of isolates being intermediate and resistant. Of which, the Campylobacter strains resisted with the highest rate to tetracycline, ciprofloxacin and enrofloxacin (98.79%), nalidixic acid (91.46%). Antibiotic susceptibility test showed that all isolated Campylobacter strains were susceptible with imipenem and meropenem of carbapenem group.
