Question

Which of the following is not a type of plague?

(a) Bubonic plague

(b) Septicemic plague

(c) Pneumonic plague

(d) Typhi plague

This question was addressed to me in an interview for internship.

This intriguing question originated from Bacterial Diseases in Humans-2 topic in chapter Human Health and Disease of Biology – Class 12

Answer 1

Correct choice is (d) Typhi plague

For explanation I would say: Plague is of three basic forms- Bubonic plague is the most common type in which formation of buboes or swelling of lymph nodes occur in the neck and armpit regions. Septicemic plague causes the rupturing of blood vessels causing black patches on the skin and pneumonic plague is the only form of plague that can be transmitted from person to person.
