The prevalence of Chlamydophila psittaci (formerly Chlamydia psittaci) infection was assessed in 95 apparently healthy, captive Amazon parrots from three breeder collections in southeastern and west-central Brazil. Cloacal swabs from 95 birds were tested for chlamydial antigen, which was detected by direct immunofluorescence (DIF), and serum samples from 44 of these birds were tested for antibodies to C. psittaci using an enzyme-linked immunosorbent assay. The prevalences of active infection as detected by DIF were 16.7%, 22.2%, and 56.1%, and seroprevalences were 100%, 87.5%, and 60% in flocks A, B, and C, respectively. We can therefore infer that C. psittaci may be widespread in captive parrot populations in Brazil.
在巴西东南部和中西部的三个饲养场收集的95只看似健康的圈养亚马逊鹦鹉中，评估了鹦鹉衣原体（原鹦鹉热衣原体）感染的流行情况。对95只鸟的泄殖腔拭子进行衣原体抗原检测，采用直接免疫荧光法（DIF）进行检测，并对其中44只鸟的血清样本采用酶联免疫吸附试验检测鹦鹉衣原体抗体。在A、B和C群中，通过DIF检测到的活动性感染患病率分别为16.7%、22.2%和56.1%，血清阳性率分别为100%、87.5%和60%。因此，我们可以推断鹦鹉衣原体可能在巴西圈养鹦鹉种群中广泛存在。
