Little is known about the true colonization rate and the localization of the bacteria in the respiratory tract. In this study, immunohistochemistry was used to examine adenoids from 69 children undergoing elective adenoidectomy. Throat swabs for polymerase chain reaction (PCR) and blood samples for serology were also obtained. <jats:italic>Chlamydia pneumoniae<\/jats:italic> was demonstrated in the adenoids by immunohistochemistry in 68 of the children. Five children (7%) had a positive <jats:italic>C. pneumoniae<\/jats:italic> PCR test from throat swabs and 14 children (20%) had detectable antibodies by the microimmunofluorescence technique.<\/jats:p><jats:p> <jats:italic>Conclusion<\/jats:italic>: The results suggest that <jats:italic>C pneumoniae<\/jats:italic> is a common finding in the adenoids of children undergoing adenoidectomy.
