[A case of pediatric Chlamydia pneumoniae infection and properties of the isolate]

Chlamydia pneumoniae was isolated from the throat of a 2-year-old girl with upper respiratory illness. The isolate, Shizuoka-37, was stained with C. pneumoniae specific monoclonal antibody (RR402), as well as the genus specific antibody (Cultureset), but not with C. trachomatis specific monoclonal antibody (Micro-Trak). C. pneumoniae genome was amplified by polymerase chain reaction in the isolate. Elementary bodies (EB) of the isolate was round shaped by electron micrograph.
