title: Chlamydiosis in pen-raised bobwhite quail (Colinus virginianus) and chukar partridge (Alectoris chukar) with high mortality.
abstract: In a flock of 12,000 bobwhite quail (Colinus virginianus) and 7200 chukar partridge (Alectoris chukar), the owner had 100% morbidity and 40%-50% mortality in birds between the ages of 2 and 4 wk. Affected birds were stunted and anorexic and had yellow/green diarrhea. Two- and 4-wk-old birds submitted for necropsy all had slight nasal discharge. Histopathologic examination revealed mild (bobwhite) to severe (chukar) rhinitis. Immunohistochemistry was positive for Chlamydia psittaci in all birds. Chlamydia psittaci organisms were demonstrated histopathologically in hematoxylin and eosin and Gimenez-stained slides. Management sanitation and treatment with chlortetracycline stopped further excessive losses. The owners were also infected. Treatment by their local physician with tetracycline alleviated symptoms.
