The microbiological flora of penile ulcerations.
The penile ulcerations of 100 consecutive men were tested for microorganisms. A polymicrobial flora was identified in the ulcers of 97 men. The microorganisms recovered from these ulcers included combinations of anaerobic and aerobic bacteria (including Mycoplasma), herpes simplex virus, yeasts, and filamentous fungi. Fifty-three study entrants had microorganisms, identified by culture or serologic tests, that were considered primary in ulcer pathogenesis. Herpes simplex virus was the most prevalent and Treponema pallidum was the next most prevalent pathogen identified. Of our patients, 5% had two recognized pathogens confirmed by laboratory tests, and only one of these was suspected at clinical examination. In addition, the study suggests that microorganisms other than Haemophilus ducreyi can produce ulcers with a morphology mimicking chancroid.
