This study surveyed avian chlamydiosis, with the aim to estimate the prevalence and potential risk factors associated with infection in psittacine birds kept as domestic pets in Thailand. Oropharyngeal swabs were collected from 120 psittacine birds that were randomly selected from hospitals in the central (Bangkok) and northeastern regions (Khon Kaen) of Thailand between 2019 and 2021. The oropharyngeal swabs were subject to polymerase chain reaction testing to detect the gene. The prevalence of was 2.5% (3/ 120, 95% confidence interval = 0.3-5.3). Of the 3 positive birds, 1 was a parrot ( species)(CP43TH) and 1 was an African grey parrot ()(CP49TH) from Bangkok; both were juvenile birds with clinical signs of disease. The third positive bird (CP12TH) was a subclinical adult sun conure () from Khon Kaen. Two sequences of samples that were previously identified in human psittacosis cases (accession numbers MK032053.1 and HM450409.1) were also examined. Since there was a low number of infected birds, potential associations between infection and various environmental variables (eg, cage cleaning, synanthropic birds, quarantine of new birds, and overcrowding) were assessed by Fisher exact tests. This study provides estimates of the prevalence and potential risk factors associated with infection in psittacine birds from central (Bangkok) and the northeastern regions (Khon Kaen) of Thailand. The detection of in captive psittacine birds demonstrates that there is a possibility for bird-to-bird transmission as well as some zoonotic potential for the human caretakers of these birds. Furthermore, larger-scale studies should be conducted to confirm these findings.
本研究对禽衣原体病进行了调查，旨在估计泰国作为家养宠物饲养的鹦鹉类鸟类中感染该病的患病率及相关潜在风险因素。2019年至2021年期间，从泰国中部（曼谷）和东北部地区（孔敬）的医院随机选取了120只鹦鹉类鸟类，采集其口咽拭子。对口咽拭子进行聚合酶链反应检测以检测该基因。患病率为2.5%（3/120，95%置信区间 = 0.3 - 5.3）。在3只阳性鸟中，1只是一只鹦鹉（品种）（CP43TH），1只是来自曼谷的非洲灰鹦鹉（）（CP49TH）；两者均为有疾病临床症状的幼鸟。第三只阳性鸟（CP12TH）是一只来自孔敬的亚临床成年太阳锥尾鹦鹉（）。还检测了先前在人类鹦鹉热病例中鉴定出的两个样本序列（登录号MK032053.1和HM450409.1）。由于感染鸟类数量较少，通过Fisher精确检验评估了感染与各种环境变量（如笼子清洁、伴人鸟类、新鸟隔离和过度拥挤）之间的潜在关联。本研究提供了泰国中部（曼谷）和东北部地区（孔敬）鹦鹉类鸟类中感染该病的患病率及相关潜在风险因素的估计值。圈养鹦鹉类鸟类中该病菌的检测表明，存在鸟类之间传播的可能性以及这些鸟类的人类照料者存在一定的人畜共患病风险。此外，应开展更大规模的研究以证实这些发现。
