Abstract

Trichomonas gallinae, a protozoan parasite causing avian trichomonosis, exhibits a widespread global prevalence. It primarily affects the upper digestive tract of birds and has resulted in significant ecological problems worldwide. This study aimed to investigate the prevalence and genotypes of T. gallinae in Anhui Province, China. A total of 1612 oropharyngeal swab samples were collected from pigeon farms in Anhui Province to determine the prevalence of T. gallinae infection. The results revealed 565 (35.1%) positive samples of T. gallinae. Significant differences in infection rates were observed among different regions and age groups. Furthermore, the ITS1/5.8 S/ITS2 region was amplified, sequenced, and subjected to phylogenetic analysis. Genotypes A and B of T. gallinae were identified, and genotype B was the dominant genotype in Anhui Province. This is the first report on the prevalence and molecular characterization of T. gallinae in Anhui Province, China. Additionally, we integrated reports on the prevalence and genotype of T. gallinae in relevant provinces in China.

中国安徽鸽子中胆毛滴虫的流行和分子鉴定

五倍子毛滴虫是一种导致禽类毛滴虫病的原生动物寄生虫，在全球广泛流行。它主要影响鸟类的上消化道，在全球范围内造成了严重的生态问题。本研究旨在调查五倍子滴虫在中国安徽省的流行情况和基因型。研究人员从安徽省的养鸽场采集了1612份口咽拭子样本，以确定五倍子嗜血杆菌的感染率。结果显示，565 份样本（35.1%）呈五倍子嗜血杆菌阳性。不同地区和年龄组之间的感染率存在显著差异。此外，还对 ITS1/5.8 S/ITS2 区域进行了扩增、测序和系统发育分析。确定了五倍子属的基因型 A 和 B，基因型 B 是安徽省的优势基因型。这是首次报道五倍子疟原虫在中国安徽省的流行情况和分子特征。此外，我们还整合了中国相关省份五倍子的流行情况和基因型。

期刊介绍： Comparative Immunology, Microbiology & Infectious Diseases aims to respond to the concept of "One Medicine" and to provide a venue for scientific exchange. Based on the concept of "Comparative Medicine" interdisciplinary cooperation between specialists in human and animal medicine is of mutual interest and benefit. Therefore, there is need to combine the respective interest of physicians, veterinarians and other health professionals for comparative studies relevant to either human or animal medicine . The journal is open to subjects of common interest related to the immunology, immunopathology, microbiology, parasitology and epidemiology of human and animal infectious diseases, especially zoonotic infections, and animal models of human infectious diseases. The role of environmental factors in disease emergence is emphasized. CIMID is mainly focusing on applied veterinary and human medicine rather than on fundamental experimental research.
