Chlamydiae are one of the causative agents of various diseases in animals and human beings, which include abortion, pneumonia, gastroenteritis, encephalomyelitis, conjunctivitis, arthritis and sexually transmitted diseases. Much work has been carried out to attempt to develop an efficient pathogen detection strategy. Here, we presented a Chlamydiaceae-specific 23S rRNA-based real-time PCR assay for simultaneous detection and quantification of four members of Chlamydiaceae family, C. trachomatis, C. psittaci, C. pneumoniae and C. pecorum, using SYBR Green and Lightcycler. The assay was characterized using plasmid constructs of the bacteria and verified on standard strains of all four species of the Chlamydiaceae and a large cohort of clinical samples collected from human and animals by comparison with fluorescence immunohistochemistry method. The results showed that the present real-time PCR assay was of high specificity and sensitivity. It was capable of detecting as few as 250fg of chlamydial DNA (equivalent to 10(-1)IFU) and was applicable to both liquid cultures and clinical samples. This assay may therefore offer a rapid, economic and reliable means for screening of the chlamydiaceae pathogens.
