Prevalence of and Risk Factors for Isolation of Meticillinresistant Staphylococcus Spp. from Dogs with Pyoderma in Northern California, Usa

Impact of systemic antimicrobial therapy on mucosal staphylococci in a population of dogs in Northwest England

“…We found that dogs reported as eating animal stools or living with hosts with hospital contact had increased risk of detecting MDR staphylococci. These findings are line with other studies describing animal stools as a source of AMR Gram‐positive bacteria, and veterinary premises or hospital contact as a risk factor for MRS, often MDR staphylococci, in dogs or humans …”

“…The population prevalence found in most studies of meticillin‐resistant S. pseudintermedius (MRSP) carriage in healthy dogs is between 0 and 4.5%, although prevalence can be higher, between 8 and 34% and up to 66% in one Japanese study in dogs with skin disease and/or exposed to other potential risk factors. Reported risk factors for mucosal carriage of, or infection with, MRS in dogs include antimicrobial therapy, contact with veterinary premises and hospital admissions . Similar risk factors have been reported or proposed for MR S. aureus (MRSA) and MR coagulase negative staphylococci (MR‐CoNS) carriage in humans; the MR‐CoNS population prevalence in healthy dogs is reported to be up to 42% .…”

“…It was surprising that beta‐lactam therapy was not associated with MRS detection in multivariable models; however, results of previous risk factor analyses also have shown inconsistent results. A few studies have identified previous antimicrobial administration as a risk for MRS/MRSP carriage/infection, but not individual drugs and/or classes, whereas other studies have not found a significant association at all . Other studies, however, have reported beta‐lactam therapy as a risk factor for MRSA infection in humans and dogs .…”
