[Specific distribution patterns and manifestations of respiratory chlamydiosis of the upper respiratory tract in different population groups].

The objective of this study was to elucidate specific distribution patterns and manifestations of respiratory chlamydiosis affecting the upper respiratory tract in different groups of the patients (both children and adults) presenting with otorhinolaryngological problems. Chlamydia were detected with the use of a combination of laboratory methods including PCR, direct immunofluorescent and imunoenzymatic assays. The study included 1329 patients. The data obtained suggest the high prevalence of chlamydial infection of the upper respiratory tract in different groups of the population. The species composition of the identified bacteria was shown to depend on the age and sex of the affected subjects.
