antigen injected into skin-if previously exposed a + action occurs-type IV hypersensitivity reaction

infection caused by a filamentous bacterium

caused by the spirochete

oral lesion is a chancre – highly infectious and forms at site where spirochete enters the body

multiple, painless, grayish-white plaques covering ulcerated mucosa
- most infectious

firm mass that eventually becomes an ulcer found on tongue and palate
- a destructive lesion that can perforate the palatal bone

VDRL (Venereal Disease Research Laboratory) test, FTA-ABS (fluorescent treponemal antibody absorption) test
