Tetracycline is expected to be as effective as erythromycin in the treatment of pneumonia due to Mycoplasma pneumoniae. In this clinical trial 12 cases with pneumonia due to Mycoplasma pneumoniae were given doxycycline (Vibramycin "Pfizer'), a long-acting derivative of tetracycline. Judging from time periods required for defervescence, improvement in symptoms such as cough and disappearance of shadows on chest X-ray, the therapeutic effect of doxycycline was excellent in 8 cases and good in 4 cases.

Pneumonias caused by atypical organisms usually have extra-pulmonary features. Chlamydial pneumonia often starts with hoarseness and fever, and respiratory tract symptoms may not appear for days. Mycoplasmal pneumonia may manifest with ear pain and a nonproductive cough. Legionnaires' disease presents with high fevers and central nervous system and gastrointestinal abnormalities. Diagnosis of chlamydial infection is accomplished with serologic testing. Patients are unresponsive to erythromycin treatment and should be started on empirical doxycycline (Doryx, Vibramycin) therapy. The presence of cold agglutinins in the appropriate clinical setting permits a presumptive diagnosis of mycoplasmal infection. Clinical diagnosis of Legionella pneumonia may be made in patients with pneumonia who also have relative bradycardia with elevated serum transaminases or hypophosphatemia with gastrointestinal or central nervous system symptoms. Erythromycin is the mainstay of treatment of legionnaires' disease, but treatment failures have been reported. Doxycycline is less expensive, has a better safety profile, and is better tolerated than erythromycin.
