Sažetak
Chlamydia psittaci is the causative agent of avian chlamydiosis, and represents a significant problem in veterinary medicine all over the world. Infection in humans is also regularly reported, especially in those closely connected to infected birds and in persons of specific occupations (veterinarians, laboratory workers, employees in poultry slaughterhouses, zoo and pet shops workers, wildlife rehabilitators). Some authors suggested that the spectrum of Chlamydiaceae spp. encountered in birds is not confined to a single species. Chlamydial infections in poultry are misdiagnosed due to symptoms similar to those caused by other pathogens, or very complex diagnosis which is also hazardous for laboratory personnel. New chlamydial agents with unknown zoonotic potential were recently detected from domestic poultry in Germany and France. Progress of diagnostic methods has also resulted in findings of some new cases of atypical chlamydial infection in hens and turkey flocks in Croatia. In different geographically part of Croatia tracheal and fecal samples were taken from two hens flocks and one turkey flock, and by using a Chlamydiaceae-specific real-time PCR assay targeting the 23S rRNA gene were found positive. Surprisingly, these PCR positive samples didn’t react with any of the C. psittaci specific tool targeting the ompA gene as well as C. abortus and C. pecorum specific tools. As recently novel Chlamydophila spp. strains have been isolated from poultry and as a specific real-time PCR has been developed targeting the conserved 16S gene and sequencing of ompA gene, the presence of novel Chlamydia sp. strain was also confirmed in turkeys and hens in Croatia. This report is our contribution to statement that the spectrum of Chlamydiaceae spp. encountered in poultry is not confined to a single species, and further investigations are needed in attempt to clarify the role of this microorganism in poultry and prevention of potential illness in humans.
