Definição
Syphilis is a sexually transmitted infection caused by the spirochetal bacterium Treponema pallidum, subspecies pallidum. It is found only in human hosts. Infection is typically acquired through direct person-to-person sexual contact with an individual who has early (primary or secondary) syphilis.[1] Most sexual transmission of syphilis probably occurs from direct contact with syphilitic lesions on the genitals or mucous membranes. Transmission from mother to fetus during pregnancy causes congenital infection.[1] Syphilis has often been described as the great imitator because many of the symptoms and signs are difficult to distinguish from other diseases.[2][Figure caption and citation for the preceding image starts]: Electron micrograph of Treponema pallidum on cultures of cotton-tail rabbit epithelium cellsCDC/Dr David Cox; used with permission [Citation ends].
