Objectives: To determine the rate of seroprevalence of Chlamydia pneumonia among patients with respiratory infection in Diyala province.
Subjects and methods : The present study was conducted in Baquba-Diyala province during the period from October /2013 to April/2014.The study group was consist of 91 samples were divided in to tow groups ,healthy and patients.

Certain demographic factors including age ,residence , sex, type of disease ,previous abortion were collected by personal interview. Detection of anti – Chlamydia pneumonia IgG antibodies was done by Enzyme-Linked Immunosorbant Assay. The Statistical Analysis System- SAS (2012) was used to effect of different factors in study parameters. Chi-square test was used for paired comparison, and percentage value of <0.05 was considered significance
Result: The results show that the positivity rate of anti- Chlamydia pneumonia IgG antibodies in patients was 17.78%. The anti- Chlamydia pneumonia IgG antibodies was statistically higher in the group age more than 20 years ,among male than female , among patients bronchitis, and insignificant between urban and rural population.
