I had both Mycoplasma Pneumoniae and Chlamydia Pneumoniae in the past.
Azythromycin, Tetralysal and I think also Doxycycline are given for both.
Giving me Azythromycin for the Chlamydia Pneumoniae and the terrible (unexpected) herxing that followed indicated my Dr to look for Bartonella, I tested positive half a year later (Chlamydia Pneumoniae was not active anymore by then).
