Human and swine isolates for which an epidemiological association has been identified are highlighted in bold
aspa, SCCmec, Rep-MP3 type
bFor these isolates results have also been confirmed by RAPD typing
ct011 isolate(s) displaying the IS256 insertion signature in the A07 fragment of the SAPIG2195 coding region (IS256::A07) (ref. [15])
dTrading of animals during the survey period has been documented between farm ID 07KR (seller) and 18CS (purchaser) (ref. [15])
