QUESTION

Fried egg colonies are seen in?

OPTIONS

(A) Anaplasma
(B) Mycoplasma
(C) Rickettsia
(D) Chlamydia

ANSWER

(B) Mycoplasma

EXPLANATION

Mycoplasma species characteristically produce small colonies with a dense central portion embedded in the agar and a lighter peripheral zone, giving the classic 'fried-egg' appearance. Therefore option B is correct; Anaplasma, Rickettsia, and Chlamydia are obligate intracellular organisms and do not form typical fried-egg colonies on routine agar.
