We reviewed the records on 30 patients with a diagnosis of C. trachomatis pneumonia.

Three patients (10%) presented with apnea. Four (13%) had conjunctivitis. Fever was present in only 3 (10%), of whom 2 also had concurrent respiratory syncytial virus infection. Peripheral eosinophilia (eosinophils > or = 400/mm3) was present in 14 (47%) patients. Hyperinflation was seen on chest x-ray in 15 patients. All infants were treated with erythromycin and responded well. The mean time to clinical improvement was 3.53 days after the start ...Continue Reading
