Trichomonas gallinae is a globally distributed protozoan parasite, mainly affect the upper avian digestive tract and can bring huge economic losses to pigeon industry. The objective of the present study was to determine the prevalence and genotypes of T. gallinae in Beijing, China. A total of 569 samples of throat swabs of pigeon were collected from pigeon farms in Shunyi District, Fangshan District, Daxing District and Miyun District of Beijing. The overall prevalence was 28.30%. The significant difference in infection rates was not observed between regions, but was found between age groups. The highest prevalence was nestling pigeons (33.16%), followed by adolescent pigeons (30.05%) and breeding pigeons (20.59%). Moreover, genotype A and B of T. gallinae were identified by sequencing the ITS1/5.8S/ITS2 regions and phylogenetic analysis. To our knowledge, this is the first report to display the prevalence and genotype of T. gallinae from Beijing, China.
鸡滴虫是一种分布广泛的原生动物寄生虫，主要感染禽类的上消化道，可给鸽业带来巨大的经济损失。本研究旨在确定中国北京地区鸡滴虫的流行情况和基因型。采集了来自北京市顺义区、房山区、大兴区和密云区的鸽场 569 份咽喉拭子样本。总体感染率为 28.30%。不同地区的感染率无显著差异，但在不同年龄组之间存在差异。感染率最高的是雏鸽（33.16%），其次是幼鸽（30.05%）和种鸽（20.59%）。此外，通过对 ITS1/5.8S/ITS2 区进行测序和系统发育分析，鉴定出了鸡滴虫的基因型 A 和 B。据我们所知，这是首次报道中国北京地区鸡滴虫的流行情况和基因型。
