Abstract

Panton-Valentine leukocidin (PVL)–positive methicillin-resistant Staphylococcus aureus (MRSA), sequence type 398 is believed to be of animal origin. We report 2 cases of infection due to PVL–positive MRSA, spa type t034, in patients in Sweden who had had no animal contact.

The Cases We report 2 patients infected with Panton-Valentine leukocidin (PVL)–positive MRSA t034
Despite several recent publications concerning ST398 MRSA, few have reported PVL in this lineage, which is believed to be of animal origin [2,4,6,13]

Summary

Introduction

Panton-Valentine leukocidin (PVL)–positive methicillinresistant Staphylococcus aureus (MRSA), sequence type 398 is believed to be of animal origin. MRSA carriage by domestic animals has been recently reported [3,4,5]. In the Netherlands in 2005, MRSA of the lineage sequence type (ST) 398, spa type t108, was detected and found to be transmittable between animals and humans, e.g., pigs and pig farmers, as well as between humans [2]. Additional spa types of the clonal lineage ST398 have been identified among humans and animals.
