Key Findings

The study identified tetracycline resistance mediated by the tet(O) gene and erythromycin resistance via the erm(B) gene and a nucleotide substitution at nt 2,075 of 23S rDNA in Campylobacter isolates from Mongolian chickens. Fluoroquinolone resistance was linked to a single-nucleotide substitution at codon 86 of the gyrA gene.
