Summary: | The pathogenic bacterium
is the most common pathogen isolated in skin-and-soft-tissue infections (SSTIs) in the United States. Most
SSTIs are caused by the epidemic clone USA300 in the USA. These infections can be serious; in 2019, SSTIs with
were associated with an all-cause, age-standardized mortality rate of 0.5 globally. Clinical presentations of
SSTIs vary from superficial infections with local symptoms to monomicrobial necrotizing fasciitis, which can cause systemic manifestations and may lead to serious complications or death. In order to cause skin infections,
employs a host of virulence factors including cytolytic proteins, superantigenic factors, cell wall-anchored proteins, and molecules used for immune evasion. The immune response to
SSTIs involves initial responders such as keratinocytes and neutrophils, which are supported by dendritic cells and T-lymphocytes later during infection. Treatment for
SSTIs is usually oral therapy, with parenteral therapy reserved for severe presentations; it ranges from cephalosporins and penicillin agents such as oxacillin, which is generally used for methicillin-sensitive
(MSSA), to vancomycin for methicillin-resistant
(MRSA). Treatment challenges include adverse effects, risk for
infection, and potential for antibiotic resistance. |
