Question: can doxycycline treat ureaplasma urealyticum?
Answer: Most mycoplasmas and ureaplasma are susceptible in vitro to macrolides (e.g. Azithromycin), tetracyclines, (e.g. Doxycycline) and fluoroquinolones (e.g. Ciprofloxacin). Azithromycin is active against Mycoplasma genitalum (considered an STD).
