# Mycoplasma (pathogen, not a drug) ## Overview *Mycoplasma* refers to a genus of bacteria that lack a cell wall. This characteristic makes them inherently resistant to many antibiotics that target cell wall synthesis (e.g., penicillins, cephalosporins). Various species can cause human infections. ## Primary Indications *Mycoplasma* species are pathogens, not treatments. Infections caused by *Mycoplasma* species require specific antibiotic therapy. Common sites of infection include the respiratory tract (*Mycoplasma pneumoniae* causing "walking pneumonia"), genitourinary tract (*Mycoplasma genitalium*, *Ureaplasma* species), and bloodstream. ## Adult Dosing Antibiotic selection and dosing for *Mycoplasma* infections depend on the specific species, site of infection, patient factors, and local resistance patterns. Commonly used agents include:
