Abstract
Atypical respiratory pathogens are now recognized as a significant cause of community-acquired pneumonia (CAP). In order to clarify the role of Mycoplasma pneumoniae and Chlamydia pneumoniae in CAP this study was conducted in adult patients to guide the empirical antibiotic therapy. Also to investigate a possible correlation between atypical pathogens in patients with CAP and comorbid factors including age, sex and other comorbid conditions. Atypical pathogens were identified in 37 (39.8%) out of 93 patients with radiologically confirmed pneumonia admitted to hospital. M. pneumoniae and C. pneumoniae using ELISA technique were identified in 22 (23.6%), and 20 (21.5%) patients, respectively. M. pneumoniae infection was decreasing with age increasing, and highest percentage of infection was (17.2%) at age group 15-24 years (p< 0.001). C. pneumoniae infection occurred in all age groups, and highest percentage of infection was (9.67%) at age group 25-34 years (p< 0.001). M. pneumoniae infection was identified more frequently in female patients (15%) than that of males (8.6%), C. pneumoniae was identified in (13.9%) of male patients and in (7.5%) of females. Comorbidities were associated with distinct microbial etiology. M. pneumoniae infection was commonly identified in patients with anemia (OR= 3.2), while C. pneumoniae infection was detected more frequently among patients with chronic renal diseases, and anemia (OR= 2.0, 2.5, respectively).
