Accepted Answer

Mycoplasma pneumoniae is a bacterium that causes respiratory tract infections. It is known to attach to ciliated cells in the respiratory tract, leading to irritation and inflammation in the lungs. It is not a fast-growing Gram-positive bacillus, and its disease is usually mild and self-limiting. It can be treated with antibiotics, although it may take longer than other bacterial infections. It is diagnosed by PCR testing, serologic tests, or cultures, and not by the appearance of "fried-egg" colonies on agar.
