Research Abstract

Panton-Valentine leukocidin (PVL) is a cytotoxin produced by Staphylococcus aureus, PVL exhibits very highly specific lytic activity against polymorphonuclear cells of human and rabbits. PVL gene-positive S. aureus is strongly associated with furunculosis and community-acquired necrotic pneumonia. We demonstrated PVL gene-positive S. aureus strains are involved in the development of multiple furuncles with more intense erythema, particularly in healthy young adults. However, the role of PVL in the development of furunculosis has not been fully elucidated. We analyzed regulatory factors of PVL toxin production and of the influence of PVL on keratinocytes, fibroblasts and endothelial cells. In addition, we investigated about PVL-carrying phage type in furunculosis.
