Isolation and antimicrobial susceptibility of Streptococcus canis from dogs

Streptococcus canis is an important opportunistic pathogen that infects animals and humans. It causes various infections, including streptococcal toxic shock syndrome, otitis externa, arthritis, skin necrotizing fasciitis, septicemia in dogs cats. can also lead to human infections. There are still very few specific studies on the identification antimicrobial resistance of this pathogen. In study, phenotypic biochemical properties 12 S. isolates obtained from vaginal discharge 11 open wound one dog with facial necrosis were determined, their susceptibility some antibiotics investigated. The isolates, such as esculin hydrolysis, hippurate synergistic CAMP-like hemolytic activity, brain hearth infusion agar containing 6.5% NaCl, carbohydrate fermentation investigated by conventional bacteriological methods. All found Group G according Lancefield serogrouping. presence species-specific 16S-23S rRNA gene intergenic spacer region (ISR) sodAint was detected all using polymerase chain reaction (PCR) method. be susceptible penicillin G, cefoperazone, ampicillin amoxicillin-clavulanic acid, resistant gentamicin neomycin.
