Turkey meat as source of CC9/CC398 methicillin-resistant Staphylococcus aureus in humans?

Livestock-associated methicillin-resistant Staphylococcus aureus (MRSA) of clonal complex (CC) 398 were first reported to cause severe infections in humans in 2005 [1]. Direct animal exposure is considered the most effective means of MRSA CC398 transmission from livestock to humans. However, about 20%–38% of MRSA CC398 cases among humans cannot be epidemiologically linked to direct livestock contact, indicating other transmission pathways [2]. As recently reported in this journal by Larsen et al [3], poultry meat may serve as a vehicle for livestock-to-human transmission. Here, we present similar findings for CC9/CC398 MRSA (displaying spa type t899 and related), which shares unique characteristics with human clinical isolates in Denmark as shown by Larsen et al [3], strongly supporting the implication of poultry, especially turkey meat, as the source of CC9/CC398.
