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.
摘要:
鸡毛滴虫是一种全球分布的原生动物寄生虫,可引起禽毛滴虫病,导致鸟类的高发病率和死亡率。本研究旨在调查患病率,遗传多样性,北京地区各种鸟类的种系亲缘关系。从家鸽中收集到的口咽拭子样本共413份,野鸽,和其他鸟类。总感染率为32.0%(132/413)。感染是在家鸽中检测到的,野鸽,还有红颈斑鸽,但不是在其他野生鸟类。分子分析确定了两种主要基因型,A和B,基因型A在野鸽中发现,基因型B在家鸽中发现。本研究为北京地区鸡巴的流行和遗传多样性提供了有价值的见解。这对于了解其病原体分布和宿主范围是有用的,以及制定预防和控制禽类毛滴虫病的策略。
