Haemophilus ducreyi PGR

Haemophilus ducreyi is a bacterium that causes a sexually transmitted infection characterized by painful ulcerative disease. The infection begins as a small, red bump on the genital or anal area, which quickly turns into a painful, open sore. The incubation period lasts from 4 to 10 days after infection. If left untreated, the infection causes significant pain and discomfort, especially during urination and sexual intercourse. Testing is recommended if ulcers are visible on the genitalia, but negative results have been obtained for Treponema pallidum, HSV 1/2 tests.
