Sažetak

Objective: Atypical pathogens are a frequent cause of pneumonia all over the world. The etiology varies according to the geographic area and age of the study population. The aim of this study was to determine the prevalence of atypical bacteria in hospitalized patients with pneumonia. Patients and Methods: From 2009 to 2012, a total of 524 patients hospitalized for pneumonia in twelve Croatian hospitals were tested for the presence of the most common atypical bacteria using ELISA and IFA. Results: Etiology was documented in 303 (57.8 %) patients. Mycoplasma (M.) pneumoniae was the most commonly detected pathogen (145/47.9 %), followed by Chlamydophila (C.) pneumoniae (80/26.4 %), Legionella spp. (56/18.5 %) and Coxiella (C.) burnetii (21/6.9 %). C. trachomatis pneumonia was found in one four-month-old baby (0.3 %), while C. psittaci was not detected. M. pneumoniae affected all age groups, with the highest prevalence in 10-19 age group (50.0 %). Prevalence of C. pneumoniae increased with age, starting with 30-39 age group. Legionella spp. was detected more commonly in patients older than 40 years. There was no age predilection for C. burnetii. Mycoplasmal and chlamydial infections occurred throughout the year. Legionelloses appeared during all seasons with more cases reported in summer and autumn. Q-fever appeared sporadically and in small outbreaks during spring and autumn. Conclusions: The results of this study showed that in 57.8 % hospitalized patients with pneumonia, atypical bacteria were found with M. pneumoniae and C. pneumoniae being most common (47.9 % and 26.4 %, respectively).
