Molecular characterization of glycoprotein antigens on surface of Treponema pallidum: comparison with nonpathogenic Treponema phagedenis biotype Reiter.

abstract：:Despite the high prevalence of cutaneous infections, little is known about the role of host immune responsiveness during Staphylococcus aureus dermatitis. We have recently described a murine model of infectious dermatitis induced by superantigen-producing S. aureus. To assess the role of neutrophils in staphylococcal ...
