Haemophilus Ducreyi

Haemophilus ducreyi refers to a particular gram-negative coccobacillus that causes the sexually transmitted disease chancroid, which is also a prime reason of genital ulceration in developing countries, symbolized by painful sores on the genitalia. The pyrogenic inflammation caused due to H. ducreyi leads to regional lymphadentis in the sexually transmitted bacillus chancroid. Chancroid begins as an erythematous popular lesion, which further disintegrates into a painful bleeding cancer with a necrotic base and ragged edge. It could be customized on chocolate agar and be ideally treated through a macrolide such as azithromycin as well as a third generation cephalosporin such as ceftriaxone.
