Plain-English summary
In this study, researchers looked at a type of bacteria called Staphylococcus pseudintermedius, which commonly lives on the skin and in the mouths of dogs and cats and can cause skin infections. They found that out of 23 animals tested, 15 had this bacteria, with 12 of those being carriers of Staphylococcus pseudintermedius. Notably, four of these carriers had a strain that was resistant to methicillin, an antibiotic. The study also showed that all veterinary staff had this bacteria on their hands, and some objects in the clinic were contaminated as well. The findings suggest that there may be a risk of spreading these resistant bacteria between pets, vets, and the environment.
Abstract
Staphylococcus pseudintermedius is the most prevalent coagulase-positive Staphylococcus inhabitant of the skin and mucosa of dogs and cats, causing skin and soft tissue infections in these animals. In this study, coagulase-positive Staphylococcus species were isolated from companion animals, veterinary professionals, and objects from a clinical veterinary environment by using two particular culture media, Baird-Parker RPF agar and CHROMagar Staph aureus. Different morphology features of colonies on the media allowed the identification of the species, which was confirmed by performing a multiplex polymerase chain reaction (PCR). Among 23 animals, 15 (65.2%) harbored coagulase-positive Staphylococcus, being 12 Staphylococcus pseudintermedius carriers. Four out of 12 were methicillin-resistant S. pseudintermedius (MRSP). All veterinary professionals had coagulase-positive Staphylococcus (CoPS) species on their hands and two out of nine objects sampled harbored MRSP. The antimicrobial-resistance pattern was achieved for all isolates, revealing the presence of many multidrug-resistant CoPS, particularly S. pseudintermedius . The combined analysis of the antimicrobial-resistance patterns shown by the isolates led to the hypothesis that there is a possible crosscontamination and dissemination of S. aureus and S. pseudintermedius species between the three types of carriers sampled in this study that could facilitate the spread of the methicillin-resistance phenotype.
