Sažetak
Obligate intracellular bacterium Chlamydia psittaci (C. psittaci) is an important etiological agent in turkey respiratory diseases. It is commonly found in Europe, causing economical losses and present a possible threat for human health. Health problems occurred on the fattening turkey’s farm, particularly related to the respiratory system over several cycles of fattening. The first clinical signs have been noticed mostly at the age of 2 weeks and lasts until 17 weeks of age. Turkeys were depressed and lethargic with respiratory signs. Some of them showed unilateral swelling of the sinuses, conjunctivitis, dyspnoea, coughing and nasal discharge. At the necropsy, lesions were present in the upper and lower respiratory tract. The samples taken from dead animals were negative for most present agents of respiratory turkey diseases, both on viruses (TRT) and mycoplasma, but E. coli infections appeared on the farms. Antimicrobial therapy was conducted by using flumequine and oxytetracycline, but the clinical signs were still present. Because the symptoms were still present, two samples from trachea were taken and were found positive on Chlamydiaceae realtime PCR, but they didn’t react with C. psittaci, as well as C. abortus and C. pecorum specific diagnostic tools. As recently novel Chlamydia sp. strains has been detected from poultry and as a specific realtime PCR has been developed, the analysis of these two samples showed relatedness to newly isolated Chlamydia. Sequencing of ompA and 16S gene confirmed this data, as well as first isolation of novel Chlamydia sp. strain from turkeys in Croatia.
