Predominance of methicillin-resistant Staphylococcus aureus SCCmec type II-CC5 and SCCmec type IV-CC1/CC8 among companion animal clinical isolates in Japan: Findings from phylogenetic comparison with human clinical isolates

Methicillin Resistant Staphylococci Isolated from Goats and Their Farm Environments in Saudi Arabia Genotypically Linked to Known Human Clinical Isolates: a Pilot Study

“…We found that MRSE isolates recovered from goat nasal swabs possessing ST35 genotype have previously also been recovered from a patient in Iraq, shared bicycle in China, birds of prey in Portugal, associated with farmers and hospital-associated isolates in Belgium, clinical isolates in Portugal, environmental sources from Germany as well as isolates recorded on pubMLST (accessed 18 November 2021) from a human source in Germany, South Korea, and Russia ( 41 – 47 ). Another genotype identified in our study, ST153 has been previously reported in isolates recovered from samples of catheter-related bloodstream infections in Belgium, nasal swabs, subgingival sites and oral rinse in Ireland and an isolate recovered from human samples in Ireland, the USA, and Latvia ( 44 , 48 , 49 ). We, therefore, hypothesize that these two S. epidermidis sequence types are not regularly reported.…”

Antimicrobial Resistance and Molecular Epidemiological Characteristics of Methicillin-Resistant and Susceptible Staphylococcal Isolates from Oral Cavity of Dental Patients and Staff in Northern Japan

“…Unlike these dominant clones, three MRSA isolates in the present study (ST8-SCC mec IVl, ST4775-SCC mec IVa, ST6562-SCC mec IVa) had unique characteristics. ST4775, a single-locus variant of ST1, was reported previously in only an MRSA with an SCC mec IVa strain from a pet cat in Japan [ 45 ], suggesting its potential relation to the animal. The ST8-SCC mec IVl isolate, which was derived from a young dental patient (13y) in the present study, was PVL-negative and harbored sec , sep , tst-1 and spj , which was characteristic of the CA-MRSA/J clone that emerged in Japan in 2003 as a cause of skin infections among children [ 31 ].…”

Antimicrobial Resistance and Type III Secretion System Virulotypes of Pseudomonas aeruginosa Isolates from Dogs and Cats in Primary Veterinary Hospitals in Japan: Identification of the International High-Risk Clone Sequence Type 235

“…Companion animals have been recognized as potential reservoirs of antimicrobial resistance genes and resistant bacteria that can be transmitted to humans ( 13 , 14 ). However, studies on P. aeruginosa virulence and antimicrobial resistance in companion animals are scarce and have focused mostly on human isolates.…”
