Abstract

This study surveyed avian chlamydiosis, with the aim to estimate the prevalence and potential risk factors associated with Chlamydia psittaci 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 C psittaci ompA gene. The prevalence of C psittaci was 2.5% (3/ 120, 95% confidence interval = 0.3-5.3). Of the 3 positive birds, 1 was a Forpus parrot (Forpus species)(CP43TH) and 1 was an African grey parrot (Psittacus erithacus)(CP49TH) from Bangkok; both were juvenile birds with clinical signs of disease. The third positive bird (CP12TH) was a subclinical adult sun conure (Aratinga solstitialis) 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 C psittaci 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 C psittaci infection in psittacine birds from central (Bangkok) and the northeastern regions (Khon Kaen) of Thailand. The detection of C psittaci 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.

聚合酶链反应检测泰国雀鸟衣原体病流行及危险因素
本研究调查了泰国家禽衣原体病,目的是评估泰国家养宠物鹦鹉衣原体感染的流行情况和潜在危险因素。从2019年至2021年期间从泰国中部(曼谷)和东北部地区(孔敬)的医院随机选择的120只鹦鹉身上收集口咽拭子。采用聚合酶链反应法检测口咽拭子中鹦鹉螺杆菌ompA基因。鹦鹉螺杆菌患病率为2.5%(3/ 120,95%可信区间= 0.3 ~ 5.3)。3只阳性鸟中,1只为曼谷福尔帕斯鹦鹉(Forpus species)(CP43TH), 1只为非洲灰鹦鹉(Psittacus erithacus)(CP49TH);均为幼鸟,均有疾病临床症状。第三例阳性鸟(cp12)为孔肯亚临床成年太阳鹫(Aratinga solstitialis)。还检测了先前在人类鹦鹉热病例中鉴定的两个样本序列(登记号为MK032053.1和HM450409.1)。由于受感染的鸟类数量较少,因此通过Fisher精确检验评估了鹦鹉螺杆菌感染与各种环境变量(如笼子清洁、鸟类共生、新鸟的检疫和过度拥挤)之间的潜在关联。本研究估计了泰国中部(曼谷)和东北部(孔敬)地区鹦鹉螺鸟类中鹦鹉螺C感染的流行情况和潜在危险因素。在圈养鹦鹉身上检测到鹦鹉热,表明存在鸟与鸟之间传播的可能性,以及对这些鸟类的人类饲养者有人畜共患的可能。此外,应该进行更大规模的研究来证实这些发现。
