Molecular characterisation and antimicrobial resistance of Streptococcus agalactiae isolates from dairy farms in China.

ABSTRACT:

Introduction

Streptococcus agalactiae (S. agalactiae) is a pathogen causing bovine mastitis that results in considerable economic losses in the livestock sector. To understand the distribution and drug resistance characteristics of S. agalactiae from dairy cow mastitis cases in China, multilocus sequence typing (MLST) was carried out and the serotypes and drug resistance characteristics of the bacteria in the region were analysed.

Material and methods

A total of 21 strains of bovine S. agalactiae were characterised based on MLST, molecular serotyping, antimicrobial susceptibility testing, and the presence of drug resistance genes.

Results

The serotypes were mainly Ia and II, accounting for 47.6% and 42.9% of all serotypes, respectively. Five seque
