Question

Chancroid is a sexually transmitted disease caused by

• A. Treponema
• B. Haemophilus
• C. Nisseria
• D. Chlamydia
• E. Trichomonas

Answer 1

Answer: (B)

Haemophilus

Chancroid is an infection caused by the bacterium Hemophilus ducreyi, which is passed from one sexual partner to another. It begins in a sexually exposed area of the genital skin, most commonly the penis and vulva (the female external genital organs including the labia, clitoris, and entrance to the vagina). Chancroid starts out as a tender bump that emerges 3 to10 days (the incubation period) after the sexual exposure. The cells that form the bump then begin to die, and the bump becomes an ulcer (an open sore) that is usually painful.

So, the correct answer is option B.
