Original publication title: Frequency, Distribution, and Antimicrobial Resistance of Coagulase-Negative Staphylococci Isolated from Clinical Samples in Dogs and Cats.
Plain-English summary
A study found that 185 strains of coagulase-negative staphylococci (CoNS) were isolated from skin and urinary tract samples of dogs and cats, indicating these bacteria can cause infections in pets. The research showed that many of these bacteria were resistant to common antibiotics, with 13.4% being methicillin-resistant coagulase-negative staphylococci (MRCoNS). This means that some infections in pets might be harder to treat due to antibiotic resistance. Pet owners should be aware of the potential for these bacteria to cause skin or urinary issues and discuss any concerns with their veterinarian, especially if their pet shows signs of infection.

Abstract
This study aimed to investigate the frequency, distribution, and antimicrobial resistance of coagulase-negative staphylococci (CoNS) obtained from clinical samples from dogs and cats and to classify any methicillin-resistant CoNS (MRCoNS). The samples were collected in 2017-2018, and species identification and antimicrobial susceptibility testing were routinely performed using the Vitek2 system. Among 1,056 staphylococci, 185 CoNS (17.5%) were obtained and included 18 species from dogs ( = 116) and 14 species from cats ( = 69). The predominant species were(31.4%)ssp.(16.2%),(10.8%), and(8.1%). The primary isolation sites were the skin and urinary tract. High levels of resistance to β-lactams (65.4%), tetracycline (44.3%), clindamycin (36.8%), and erythromycin (30.8%) were observed. Twenty-five MRCoNS (13.4%), mainly( = 8),( = 6), andssp.( = 5), were identified. SCCtype V ( = 8) was the most common type, followed by SCCtype IV ( = 6) and SCCtype III ( = 2), whereas nontypable SCCwere classified into nine MRCoNS. Some CoNS have been recorded in humans, and these might be transferred to and cause subsequent infections in humans. Moreover, the diversity of SCCtypes and resistant strains suggested that they may serve as a reservoir of resistance genes among staphylococci.
