Isolation of ST398 methicillin-resistant <i>Staphylococcus aureus</i> from pigs at abattoirs in Tohoku region, Japan

Abstract: Here, we investigated the presence of ST398 livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) in nasal swabs of 420 slaughtered pigs from 84 farms at three abattoirs in Tohoku, Japan. MRSA were isolated from 13 (3.1%) samples from 9 (10.7%) farms at two abattoirs. All isolates were classified as ST398 and were resistant to ampicillin and tetracycline. Ten and three isolates were classified as Staphylococcal Cassette Chromosome mec (SCC … Show more

“…The results of our current and previous studies [17] showed that ST398 MRSA has spread on pig farms in the Tohoku region. Pigs used for breeding in Japan are imported from Europe and North America, where ST398 MRSA is prevalent [6,9,22], and imported pigs and their offspring are transferred to pig farms throughout Japan.…”

“…In recent decades, the emergence and increasing prevalence of livestock-associated MRSA (LA-MRSA), particularly sequence type 398 (ST398) in pigs, have become a global concern [11,[25][26][27][28]. Since ST398 MRSA was isolated from pigs in Japan in 2012, it has been isolated from pigs in the Kanto and Tohoku regions of Japan as well [20,21]. Typing of both staphylococcal cassette chromosome mec (SCCmec) and region X of the protein A gene (spa) revealed that divergent types of MRSA are distributed in Japan.…”
