摘要

已发现蝙蝠的吸血外寄生虫含有对农业和医学具有重要意义的昆虫特异性病毒和脊椎动物感染病毒。虽然其中一些病毒可能来自蝙蝠,但这些病毒可能来自蝙蝠的体外或它们的血食。蝙蝠除了日常饮食外,还会在梳理毛发时吃掉许多体外寄生虫。外寄生虫上和寄生虫中的所有微生物都会在蝙蝠摄入外寄生虫后进入蝙蝠肠道。为了研究蝙蝠体外寄生虫病毒组对蝙蝠肠道病毒微生物组的潜在影响,我们比较了从中国云南省采集的蝙蝠及其吸血体外寄生虫的病毒序列。尽管所有共同出现的病毒都是噬菌体,但我们观察到蝙蝠体内的病毒比其体外寄生虫体内的病毒要多,而且蝙蝠体内的预测病毒组比蝙蝠体外寄生虫体内的病毒组更加多样化。我们的分析表明,尽管大量的体外寄生虫通过进食进入了蝙蝠的消化道,但在蝙蝠和它们的体外寄生虫之间只有很少的共存/共享病毒,这些体外寄生虫可能不是蝙蝠病毒组多样性的主要驱动因素。我们的研究结果为评估蝙蝠外寄生虫作为蝙蝠感染病毒的潜在来源提供了必要的初步数据。

Viromes of arthropod parasites and their hosts: The case of bats and bat ectoparasites

Blood feeding ectoparasites of bats have been found to contain insect-specific and vertebrate-infecting viruses of agricultural and medical importance. While it is plausible that some of these are of bat origin, those would be sourced either from the bat exterior or their blood meal. Bats, in addition to their regular diets, consume numerous ectoparasites during grooming. All microbes on and in the ectoparasites would then be introduced into the bat gut upon ingestion of the ectoparasites. To investigate the potential impact of bat ectoparasite viromes on the gut viral microbiome of bats, we compared virus sequences from bats and their blood feeding ectoparasites collected from Yunnan Province, China. Although all the co-occurring viruses were bacteriophages, we observed that bats contained a larger set of viruses than their ectoparasites, and that the set of predicted viruses present in the bats were more diverse than those present in bat ectoparasites. Our analysis suggests that despite a heavy influx of ectoparasites into the digestive tract of bats through consumption, there are only few co-occurring/shared viruses between bats and their ectoparasites, and that these ectoparasites may not be a major driver of bat virome diversity. Our findings provide necessary preliminary data for the evaluation of bat ectoparasites as a potential source of bat infecting viruses.
