传染病威胁着野生动物种群的健康和生存。因此，宿主多样性、宿主丰度和寄生虫感染之间的关系是疾病生态学和保护研究的重要方面。在这里，我们报告的流行模式的鸟类疟原虫和变形血杆菌感染和主机相对丰度的影响，抽样728野生捕获的鸟类代表124种在7个地理分布广泛的网站在中国南方。两种血原虫寄生虫，疟原虫和变形血原虫，总患病率为29.5%，其中变形血原虫占22.0%，疟原虫占7.8%。血变形杆菌的流行率在不同的鸟类宿主家庭之间差异显着，与最高的流行率在油桃科，Pycnonotidae和Muscicapidae，而疟原虫的流行率在宿主物种之间差异显着。共鉴定出79个线粒体谱系，其中疟原虫25个，血变形杆菌54个，其中80%为首次报道。这些寄生虫之间的系统发育关系表明血变形杆菌比疟原虫更强的宿主种特异性。在疟原虫和血变形杆菌中发现了支持宿主家族（Timaliidae）的特异性分支。血变形菌属树显示了区域性的分支，而疟原虫属的分支“分散”在不同的地理区域。有趣的是，各地理区域之间疟原虫和变形血杆菌的流行率存在统计学显著差异。此外，疟原虫和血变形杆菌的流行与宿主相对丰度没有显着相关性。进一步的努力将集中在探索寄生虫流行与性别，年龄和宿主免疫防御之间的关系。
Infectious diseases threaten the health and survival of wildlife populations. Consequently, relationships between host diversity, host abundance, and parasite infection are important aspects of disease ecology and conservation research. Here, we report on the prevalence patterns of avian Plasmodium and Haemoproteus infections and host relative abundance influence based on sampling 728 wild-caught birds representing 124 species at seven geographically widespread sites in southern China. The overall prevalence of two haemoprotozoan parasites, Plasmodium and Haemoproteus, was 29.5%, with 22.0% attributable to Haemoproteus and 7.8% to Plasmodium. Haemoproteus prevalence differed significantly among different avian host families, with the highest prevalence in Nectariniidae, Pycnonotidae and Muscicapidae, whereas Plasmodium prevalence varied significantly among host species. Seventy-nine mitochondrial lineages including 25 from Plasmodium and 54 from Haemoproteus were identified, 80% of which were described here for the first time. The phylogenetic relationships among these parasites indicated stronger host-species specificity for Haemoproteus than Plasmodium. Well-supported host-family (Timaliidae) specific clades were found in both Plasmodium and Haemoproteus. The Haemoproteus tree shows regional subclades, whereas the Plasmodium clades are “scattered” among different geographical regions. Interestingly, there were statistically significant variations in the prevalence of Plasmodium and Haemoproteus among the geographical regions. Furthermore, the prevalence of Plasmodium and Haemoproteus were not significantly correlated with host relative abundance. Further efforts will focus on exploring the relationships between parasite prevalence and sex, age, and immune defense of the host.
