Plain-English summary
A study found that 6% of dogs and cats with eye discharge had infections caused by methicillin-resistant Staphylococcus aureus (MRSA) or Staphylococcus pseudintermedius. Specifically, 3% of the cases were linked to each type of bacteria, with some showing resistance to common antibiotics like penicillin and clindamycin. This highlights the importance of monitoring and treating these infections carefully, as they can spread between pets and humans. If your pet has eye discharge, it's crucial to consult your veterinarian for appropriate testing and treatment options.

Abstract
Objectives Methicillin-resistant Staphylococcus (MRS) has originated, spread extensively, and become a prominent source of bacterial infections in both human and animal. Methods We report the prevalence, genetic diversity, and antimicrobial resistance pattern of Staphylococcus pseudintermedius and Staphylococcus aureus strains isolated from dogs and cats with eye discharges. Results A total of 12 (6.0%) coagulase-positives staphylococci were identified as (6/200, 3%) S. aureus and (6/200, 3%) S. pseudintermedius. The phenotypic methicillin resistance of S. aureus and S. pseudintermedius were 50.0% (3/6) and 16.7% (1/6), respectively. None of the isolates showed biofilm formation in the microtiter plate assay. The highest resistance (50.0%) for S. pseudintermedius strains was detected against clindamycin and tetracycline. 67.0% of S. aureus isolates were resistant to penicillin-G. The PCR analysis conducted for detection of mecA gene indicated that only one S. aureus isolated from a cat was mecA gene positive. Phylogenetic analysis based on repetitive sequence-based PCR (rep-PCR) showed that all strains were typable and generated PCR products ranging from 800 bp to 4,400 bp. The lineages ST241 and the novel ST2361 in multi-locus sequence typing (MLST) analysis were detected in one methicillin-susceptible S. pseudintermedius and methicillin-resistant S. pseudintermedius of dogs, respectively. In addition, the lineages ST4155 and ST7217 of two methicillin-resistant S. aureus strains of cats were connected epidemiologically to previously reported cases. Conclusions These results indicate epidemiologically related strains (ST241, ST4155, and ST7217) transferring between animals and humans. Therefore, the strategies to combat the widespread MRS should be based on collaboration between human and veterinary medicine under the One Health concept.
