Prevalence and Characteristics of Streptococcus canis Strains Isolated from Dogs and Cats

Abstract

To determine the prevalence of Streptococcus canis in dogs and cats, a total of 926 swabs were examined bacteriologically in the period from 2003 to 2005. Eighty-six isolates obtained from various anatomical locations were further characterized for their phenotypic properties. The most frequently isolated biotype produced phosphatase, leucine amidopeptidase, arginine dihydrolase, alpha-D-and beta-D-galactosidase and fermented lactose and ribose. Additional identification by species-specific amplification of the 16S-23S rRNA intergenic spacer region was consistent with S. canis. All isolates were susceptible to penicillin G and ampicillin. The least effective antimicrobial agent was found to be tetracycline (only 33.8% of susceptible strains). Prevalence, S. canis, biochemical properties, 16S-23S rRNA intergenic spacer region

Cytological and Microbiological Analysis of Canine Otitis Externa

“…After performing 16S rRNA PCR and gene sequencing, four isolates from healthy group were identified as Staphyloccus pseudintermedius (2 isolates), Bacillus cereus (1 isolate) and Staphylococcus shleiferi (1 isolate). These findings were in agreement with that of Lysková et al (2007) who reported isolation of Staphylcococcus spp., Bacillus spp. and Malassezia pachydermatis spp., in normal healthy canine ears.…”

“…They also reported that the Staphylococcus spp., were highly sensitive to chloramphenicol which was seen in our study. Lysková et al (2007) also reported sensitivity of Staphylococcus spp. and Pseudomonas spp., to gentamicin and ciprofloxacin.…”

Antimicrobial susceptibility monitoring of dermatological bacterial pathogens isolated from diseased dogs and cats across Europe (ComPath results)

“…In the case of uncomplicated skin infections, often only Staph. Beta-haemolytic streptococci have also been isolated from dogs with dermatitis (Lyskov a et al 2007;Lamm et al 2010). or Pseudomonas aeruginosa, may be present in addition to Staph.…”

“…pseudintermedius (Dowling 1996;Ihrke 2006). Beta-haemolytic streptococci have also been isolated from dogs with dermatitis (Lyskov a et al 2007;Lamm et al 2010). In ear infections, the major causative organisms beside yeasts are Staph.…”

Vaginal isolation of beta‐haemolytic Streptococcus from bitches with and without neonatal deaths in the litters

“…() and S. dysgalactiae strains isolated from the human pharynx (Rantala, ; Woo, Fung, Lau, Wong, & Yuen, ). In contrast, Lysková, Vydržalová, Královcová, and Mazurová () found some S. canis strains with vancomicin resistance isolated to external ears canal, vaginal mucosa, pharynx and oral cavity, conjunctivae, skin and the rectum in dogs. Gianneechini et al.…”
