Avian malaria parasites provide an important model for studying host-pathogen interactions, yet understanding their dynamics in vectors under natural conditions is limited. We investigated the effect of vector abundance, species richness and diversity, and habitat characteristics on avian prevalence and lineage richness in across 45 urban, natural, and rural localities in southern Spain Analyzing 16,574 mosquitoes grouped in 768 mosquito pools, 32.7% exhibited parasite presence. 13 different lineages were identified, with the lineage SYAT05 being the most commonly found. Parasite prevalence positively correlated with the distance to saltmarshes and rivers, but negatively with the distance to total water source. Parasite lineage diversity was higher in natural than in rural areas and positively correlated with mosquito species richness. These results emphasize the complex dynamics of avian in the wild, with habitat characteristics and vector community driving the parasite transmission by mosquito vectors.
鸟类疟原虫为研究宿主与病原体的相互作用提供了重要模型,但在自然条件下了解其在媒介中的动态变化仍很有限。我们调查了西班牙南部45个城市、自然和农村地区的媒介丰度、物种丰富度和多样性以及栖息地特征对鸟类疟疾流行率和谱系丰富度的影响。分析了768个蚊池中的16574只蚊子,32.7%的蚊子体内有疟原虫。鉴定出13个不同的谱系,其中SYAT05谱系最为常见。疟原虫流行率与到盐沼和河流的距离呈正相关,但与到总水源的距离呈负相关。自然地区的寄生虫谱系多样性高于农村地区,且与蚊种丰富度呈正相关。这些结果强调了野生鸟类疟疾的复杂动态,栖息地特征和媒介群落驱动着蚊媒传播寄生虫。
