Chlamydia psittaci was isolated from the spleen of a moribund white-winged dove (Zenaida asiatica). The isolate was serotyped as the serovar B that is commonly isolated from pigeons. A fourfold increase in the titer of antichlamydial IgM activity occurred in that bird in paired serum samples tested by chlamydial elementary body agglutination (EBA) and a greater than or equal to fourfold decrease of IgG occurred by direct complement fixation (DCF). The increases or decreases of EBA and DCF titers in other clinically ill birds that were treated with tetracycline varied, as normally occurs in cases of avian chlamydiosis. Titers in clinically normal birds were consistent with past infections. These birds were from a captive group of about 200 birds to be used for breeding and reproduction research. A small sample of recently caught wild birds was serologically negative for chlamydial antibody activity.
从一只濒死的白翅鸽（泽纳ida asiatica）的脾脏中分离出鹦鹉热衣原体。该分离株被血清型鉴定为通常从鸽子中分离出的血清型B。通过衣原体原体凝集试验（EBA）检测，该鸟配对血清样本中的抗衣原体IgM活性滴度增加了四倍，通过直接补体结合试验（DCF）检测，IgG滴度下降了大于或等于四倍。用四环素治疗的其他临床患病鸟类的EBA和DCF滴度变化各异，这在禽衣原体病病例中通常会出现。临床正常鸟类的滴度与既往感染情况一致。这些鸟来自一群约200只用于繁殖和生殖研究的圈养鸟类。一小部分最近捕获的野生鸟类衣原体抗体活性血清学检测呈阴性。
