Chancroid Haemophilus Ducreyi

Chancroid usually presents as single or multiple soft sores that are painful and bleed easily. The base is necrotic and the borders ragged. Painful inguinal adenitis is common, and buboes develop that may rupture and result in extensive ulceration.


Donovanosis presents with one or more papules or nodules that develop into friable ulcers that gradually increase in size. Lesions tend to be painless. Lymph nodes swell and infection may spread to tissue above the lymph nodes, leading to an abscess known as a psuedo-bubo or to skin ulceration.
