The characterization and correlation between the phenotypic and genotypic resistance of Campylobacter spp . isolates from commercial broilers and native chickens in the south of Thailand

Abstract

High Campylobacter prevalence in chickens; C. jejuni more prevalent than C. coli.Susceptibility to macrolides but resistance to quinolones/tetracyclines in isolates.Homogeneous resistance patterns within farms; higher in broilers than in native birds.Partial association between phenotypic and genotypic resistance among isolates.

Keywords: Antimicrobial resistance; Campylobacter; Thailand; commercial broilers; genotype; native chickens; phenotype.
