Question

Which one of the following statements about Mycoplasma is wrong?

• A. They cause diseases in plants
• B. They are also called PPLO
• C. They are pleomorphic
• D. They are sensitive to penicillin

Answer 1

The correct option is D They are sensitive to penicillin

PPLO are mycoplasmas which are Pleuropneumonia Like Organisms. Mycoplasma is a genus of bacteria that lack a cell wall around their cell membrane. Without a cell wall, they are unaffected by many common antibiotics such as penicillin or other beta-lactam antibiotics that target cell wall synthesis. They cause diseases in plants like mulberry dwarf, grassy shoot of sugarcane, citrus greening, little leaf of brinjal, etc.
