Recently, several trichomonads species including Trichomonas tenax, Trichomonas brixi and Tetratrichomonas sp. have been found in the oral cavities in dogs and cats. Although the number of dogs and cats is rapidly increasing in China, the prevalence and zoonotic potential of oral trichomonads in dogs and cats remains unclear.
This study investigated the molecular prevalence of oral trichomonads in pet dogs and cats in East China using molecular methods.
A total of 386 dogs and 497 cats from five pet clinics in Anhui Province and Shanghai city were determined in terms of the occurrence and species distribution of oral trichomonads using the PCR amplification and sequence of ITS1-5.8S rRNA-ITS2 region.
The overall prevalence of oral trichomonads in dogs and cats in this study was 2.8% (25/883), with infection rates of 2.6% (10/386) in dogs and 3.0% (15/497) in cats. Initial evaluation of potential risk factors found no significant difference in prevalence of oral trichomonads between age and gender form tested dogs or cats. Sequence alignment and phylogenetic analyses revealed the presence of T. tenax and T. brixi in pet dogs and cats in East China.
The present work represents the first report about the prevalence and zoonotic potential of oral trichomonads in dogs and cats in China. Considering the zoonotic potential of T. tenax, the huge population of companion animals in China, and the close relationship between owners and companion animals, transmission between humans and domestic animals should be taken into consideration.
最近，在犬猫口腔中发现了几种毛滴虫，包括口腔毛滴虫、布氏毛滴虫和四毛滴虫属。尽管中国犬猫数量迅速增加，但犬猫口腔毛滴虫的流行情况和人畜共患病潜力仍不清楚。
本研究采用分子方法调查中国东部地区宠物犬猫口腔毛滴虫的分子流行情况。
使用PCR扩增和ITS1-5.8S rRNA-ITS2区域测序，对来自安徽省和上海市五家宠物诊所的386只犬和497只猫进行口腔毛滴虫的发生情况和种类分布测定。
本研究中犬猫口腔毛滴虫的总体患病率为2.8%（25/883），犬的感染率为2.6%（10/386），猫的感染率为3.0%（15/497）。对潜在风险因素的初步评估发现，受试犬猫的年龄和性别在口腔毛滴虫患病率上没有显著差异。序列比对和系统发育分析显示，中国东部宠物犬猫中存在口腔毛滴虫和布氏毛滴虫。
本研究是中国关于犬猫口腔毛滴虫患病率和人畜共患病潜力的首次报告。考虑到口腔毛滴虫的人畜共患病潜力、中国庞大的伴侣动物数量以及主人与伴侣动物之间的密切关系，应考虑人畜之间的传播。
