INTRODUCTION
Staphylococcus is a diverse genus including several species of clinical importance to human and veterinary medicine. Little is known about the diversity of staphylococci, especially coagulase negative species within the microbiota of dogs and cats. The pets of remote NSW represent a unique population in which to investigate skin microbiota with low levels of exposure to antimicrobials and contact with a human population with a high incidence of antimicrobial-resistant staphylococcal infections.
OBJECTIVES
This study aimed to characterise the staphylococcal microbiota of a population of dogs and cats from remote NSW, Australia.
METHODS
Three swabs (nostrils, oropharynx, perineum) were collected from dogs and cats participating in a Companion-Animal Health Program in north-west
NSW. Swabs were cultured on selective media for Staphylococcus spp. and for methicillin-resistant Staphylococcus spp. Species identification was confirmed by matrix-assisted laser desorption/ionisation- time of flight (MALDI-TOF) mass spectrometry.
RESULTS
Isolates from 218 dogs and 39 cats were identified to species level. MRSA was isolated from 2.3% of dogs and no cats. No methicillin-resistant S. pseudintermedius was isolated from dogs or cats. The diversity of Staphylococcus spp. was high with 16 species represented, including 13 coagulase negative species (Tables 1&2). Staphylococcus pseudintermedius was the most frequent isolate from dogs and S. felis from cats. Staphylococcus aureus was only isolated from 3.7% of dogs.
CONCLUSIONS
MRSA was isolated from a high proportion of dogs relative to comparable populations, despite a
low prevalence of S. aureus. This study confirms staphylococcal microbiota of dogs and cats is diverse and includes a wide range of coagulase negative species.
