Chancroid is a sexually transmitted infection, clinically manifested by acute ulcers on the external genitalia and inguinal lymphadenopathy with bubo formation. Although it was initially described by Ricord in 1838, it was first differentiated from syphilis by Bassereau in 1852. Ducrey described the etiologic agent in 1889, but its cultivation on solid media was difficult and unpredictable. As a result, controversy about Haemophilus ducreyi and its role in chancroid continued until recently. Newer technologies that facilitate the culture of H. ducreyi now permit a specific diagnosis.
