Avian chlamydiosis is an infection caused by obligate intracellular, gram-negative bacteria belonging to the Chlamydiaceae family. Birds can be hosts of several Chlamydia species, including Chlamydia avium, which has only been detected in pigeons and psittacine birds. In this study, depression, respiratory distress, and mortality were noted among psittacines belonging to a large aviary with 35 different avian species. On the basis of immunohistochemistry and PCR testing, chlamydiosis was diagnosed in affected birds. Gross and histopathologic lesions were mainly observed in the spleen and gastrointestinal tract. Chlamydia avium was detected in four psittacines by PCR, including two dead birds and two individuals exhibiting respiratory distress. Increased aspartate aminotransferase and lactate dehydrogenase values and anemia were consistently identified in affected birds. Administration of doxycycline, combined with hepatoprotectors and vitamins, was effective in stopping mortality and bacterial shedding.
禽类衣原体病是一种由专性细胞内、革兰氏阴性细菌引起的感染，这些细菌属于衣原体科。鸟类可能是几种衣原体的宿主，包括仅在鸽子和鹦鹉中检测到的鹦鹉衣原体。在这项研究中，一个拥有 35 种不同鸟类的大型鸟舍中的鹦鹉出现了抑郁、呼吸窘迫和死亡的情况。根据免疫组织化学和 PCR 检测，确诊了受感染鸟类的衣原体病。受影响的鸟类主要观察到脾脏和胃肠道的大体和组织病理学病变。通过 PCR 在四只鹦鹉中检测到鹦鹉衣原体，包括两只死亡的鸟和两只出现呼吸窘迫的个体。受影响的鸟类的天冬氨酸转氨酶和乳酸脱氢酶值升高和贫血是一致的。联合使用多西环素、肝保护剂和维生素治疗，有效地阻止了死亡率和细菌脱落。
