Methicillin-resistant (MRSA) strains showing POT type 106-77-113 have been associated with USA300. Additionally, many strains produce Panton-Valentine Leukocidin (PVL). Until 2018, 106-77-113 was the most dominant POT-type PVL-producing bacteria isolated in our hospital; however, in 2018, one strain with POT type 106-255-121 was isolated, and thereafter, since 2019, an increasing trend towards isolation of this strain has been observed.

Many institutions use POT as a molecular epidemiological method for analyzing horizontal transmission in methicillin-resistant (MRSA). However, typing and analyzing MRSA only based on POT, with high detection frequency, has some limitations.
