OBJECTIVE: The aim of the study was an evaluation of results of Chlamydia trachomatis antigen detection by means of direct immunofluorescence in samples from patients suspected from this infection.
DESIGN: Retrospective study.
SETTING: Institute of clinical microbiology, University Hospital and Medical Faculty of Charles University, Hradec Králové.
METHODS: Samples from females were swabs from uterine cervix, vagina and urethra, from male urethral swabs; moreover conjunctival swabs, bronchoalveolar irrigation, lower respiratory tract aspirates and sputum. Samples were fixed and "dyed" with monoclonal specific antibody labeled by fluorescent dye in the lab with a commercial diagnostic kit and they were evaluated microscopically after adding a drop of glycerol and covering with a top slide.
RESULTS: Within a group of 6126 samples from patients suspected from Chlamydia infection we have found positivity in 14.4%. Of this subgroup 14.1% in samples from genitourinary tract of females and 15.2% in males, 14.1% from conjunctival swabs and 3.7% from lower respiratory tract. According to an age differentiation, positive samples in individual life-decades from genitourinary tract were 0-13-14.4-13.9-13.9 and in females over 60 13.9%. In males the corresponding walues were 0-21.4-15.1-16-13.4 and those over 60 years 16%. So, the highest positivity in our region has been detected in samples from young men aged 20-30, where it is nearly two-fold higher comparison to age-matched females.
CONCLUSION: Direct detection of Chlamydia trachomatis antigen with immunofluorescence method still remains a reliable diagnostic tool. But for a control or confirmation of disputable results it is inconditionally necessary to have at least one more method available, e.g. PCR.
