[A report of 4 cases from whom Chlamydia pneumoniae was isolated].
Chlamydia pneumoniae (C. pneumoniae) was isolated from respiratory tract of 4 girls. Case 1 is 5-year-old, diagnosed as pneumonia, had had a prolonged productive cough. She was treated with RKM with improvement of symptoms, however, C. pneumoniae was isolated repeatedly and was not deleted. Neither anti-mycoplasmal nor viral antibodies were positive and no significant pathogens were cultured from nasophrayngeal swabs. Case 2, the sister of case 1, is a 3-year-old girl with acute bronchitis treated with EM. C. pneumoniae was negative on the tenth day after treatment. Case 3, a 5-year-old girl, had a fever and was diagnosed as bronchopneumonia with a mild attack of bronchial asthma. She was initially treated with CFIX followed by therapy including EM. Her symptoms had disappeared after treatment and anti-mycoplasmal antibody was 1:320. Case 4 was an asymptomatic carrier of C. pneumoniae. Specimen was obtained at regular health examinations of junior high school. C. pneumoniae was isolated from a 14-year-old girl without respiratory symptoms. Clinical figures of C. pneumoniae infections varies from asymptomatic carrier to pneumonia. Pathogens other than C. pneumoniae could modify symptoms of infections. Precise examinations of these cases would establish a proper management of a C. pneumoniae infection.
