The aim of this study was to evaluate the health situation of chukar partridges through several diagnostic methods. We investigated a total of 224 birds in eighteen populations throughout Turkey, fourteen wild and four captive. The molecular sexing method was used for gender identification. Clinically, traumatic lesions and inflammatory reactions were the most commonly observed in the eyes and extremities of the Chukar Partridges in the breeding stations. At necropsy, the most common findings were enteritis and liver lesions. At the histopathological examination, pneumonia, anthracosis, and inflammatory changes in the digestive system were among the common findings. Interestingly, liver parasites were found in wild samples. At the immunohistochemical examinations, the tissues were evaluated for Marek's disease (MD), Adenovirus, Avian mycobacteriosis (AMB), and Aspergillosis. While MD and AMB were not found in breeding stations, we determined them from wild populations. Aspergillus was found in both wild and captive populations; Adenovirus antigens were found only in breeding stations. When the captive and wild populations were evaluated together, MD 1.3%, AMB 0.9%, Aspergillosis 1.3%, Adenovirus 1.8% were found. The relation between sex and diseases was also examined. As a result, the data of this study showed that chukar partridges from both breeding stations and wild populations are not an important source of diseases, but especially released partridges from breeding stations may carry some microorganisms. For that reason, captive populations should be regularly monitored for contagious diseases.(AU)
