Abstract

Trichomonas gallinae is a globally distributed protozoan parasite that causes avian trichomoniasis, leading to significant morbidity and mortality in birds. The present study aims to investigate the prevalence, genetic diversity, and phylogenetic relationship of T. gallinae in various bird species in Beijing. A total of 413 oropharyngeal swab samples were collected from domestic pigeons, wild pigeons, and other bird species. The overall prevalence of T. gallinae infection was 32.0% (132/413). The infection was detected in domestic pigeons, wild pigeons, and red-necked turtledoves, but not in other wild birds. Molecular analysis identified two predominant genotypes, A and B, with genotype A found in wild pigeons and genotype B found in domestic pigeons. The present study provides valuable insights on the prevalence and genetic diversity of T. gallinae in Beijing. This can be useful for understanding its pathogen distribution and host range, and the development of strategies for the prevention and control of avian trichomoniasis.

中国北京五倍子毛滴虫流行病学调查

五倍子毛滴虫（Trichomonas gallinae）是一种分布于全球的原生动物寄生虫，可引起鸟类滴虫病，导致鸟类大量发病和死亡。本研究旨在调查五倍子毛滴虫在北京各种鸟类中的流行率、遗传多样性和系统发育关系。本研究共收集了 413 份口咽拭子样本，分别来自家鸽、野鸽和其他鸟类。五倍子嗜血杆菌的总感染率为 32.0%（132/413）。在家鸽、野鸽和红颈斑鸠中都检测到了这种病毒，但在其他野生鸟类中没有检测到。分子分析确定了两种主要基因型，即 A 型和 B 型，其中 A 型基因在野鸽中发现，B 型基因在家鸽中发现。本研究为了解北京五倍子嗜血杆菌的流行情况和遗传多样性提供了宝贵的信息。这有助于了解其病原体分布和宿主范围，以及制定禽毛滴虫病的预防和控制策略。

期刊介绍： The International Journal for Parasitology: Parasites and Wildlife (IJP-PAW) publishes the results of original research on parasites of all wildlife, invertebrate and vertebrate. This includes free-ranging, wild populations, as well as captive wildlife, semi-domesticated species (e.g. reindeer) and farmed populations of recently domesticated or wild-captured species (e.g. cultured fishes). Articles on all aspects of wildlife parasitology are welcomed including taxonomy, biodiversity and distribution, ecology and epidemiology, population biology and host-parasite relationships. The impact of parasites on the health and conservation of wildlife is seen as an important area covered by the journal especially the potential role of environmental factors, for example climate. Also important to the journal is ''one health'' and the nature of interactions between wildlife, people and domestic animals, including disease emergence and zoonoses.
