Molecular subtyping and antimicrobial susceptibility of Streptococcus dysgalactiae subspecies equisimilis isolates from clinically diseased pigs.

ABSTRACT:

Background

Streptococcus dysgalactiae subspecies equisimilis (SDSE) acts as an etiological agent for lameness, neurological signs, and high mortality in pigs. Despite its importance in pig industries and zoonotic potential, little is known about the effects of this pathogen.

Objectives

This study aimed to determine the molecular characteristics and antimicrobial resistance of SDSE strains isolated from diseased pigs.

Methods

A total 11 SDSE isolates were obtained from diseased pigs. Bacterial identification, PCR for virulence genes, emm typing, and antimicrobial resistance genes, multilocus sequence typing, and antimicrobial susceptibility test were performed.

Results

Nine isolates were from piglets, and 8 showed lameness, sudden death, or
