in MRSA ST398 Infection Patterns

Any one who has insights into the history of 398 shoukd comment below

The susceptibilities of two collections of Staphylococcus aureus isolated in 1970s and 2006 from poultry were determined to 12 antimicrobial agents. For 8 antibiotics the percentage of resistance was significantly higher in the recent isolates. Ten recent isolates were MRSA and had spa types t011 and t567 belonging to multi-locus sequence type 398. This is the first report of the “livestock-associated” MRSA from healthy poultry.

Antimicrobial resistance of old and recent Staphylococcus aureus isolates from poultry: first detection of livestock-associated methicillin-resistant strain ST398 — Nemati et al., 10.1128/AAC.00613-08 — Antimicrobial Agents and Chemotherapy.
