☜☆ Clinical Manifestations
Mycoplasma pneumoniae infection is a disease of the upper and lower respiratory tracts. Cough, fever, and headache may persist for several weeks. Convalescence is slow. Ureaplasma urealyticum infection causes nongonococcal urethritis in men, resulting in dysuria, urgency, and urethral discharge.
Structure, Classification, and Antigenic Types
Mycoplasmas are spherical to filamentous cells with no cell walls. There is an attachment organelle at the tip of filamentous M pneumoniae, M genitalium, and several other pathogenic mycoplasmas. Fried-egg-shaped colonies are seen on agar. The mycoplasmas presumably evolved by degenerative evolution from Gram-positive bacteria and are phylogenetically most closely related to some clostridia..☆☞
