MRSA st398 - Pig MRSA - More resistance found

More problems for Britain's corrupt State Veterinary Service, who continue to claim British pigs are free of MRSA st398.

This is a bigger scandal than Murdoch and the 'News of the World.'

A novel streptogramin A-, pleuromutilin-, lincosamide-resistance determinant, Vga(E), was identified in porcine methicillin-resistant Staphylococcus aureus (MRSA) ST398. The vga(E) gene encoded a 524-amino acid protein belonging to the ABC transporter family. It was found on a multidrug-resistant transposon, Tn6133, which was comprised of the Tn554 with a stably integrated 4,787-bp DNA sequence harboring vga(E). Detection of Tn6133 in several porcine MRSA ST398 isolates and its ability to circularize suggests a potential for dissemination.
