Abstract

The relationship between hosts and viruses is influenced by various factors. One potential factor is sociality. In social organisms such as ants, the interaction between hosts and viruses might differ from those of solitary organisms due to their unique ecology. We previously isolated a double-stranded RNA toti-like virus, Camponotus yamaokai virus (CYV), from the arboreal ant Camponotus yamaokai. The ant exhibits a polygynous colony structure with multiple queens and within-nest mating behaviors. Such unique ecological traits may have driven the evolution of a distinctive relationship with the virus. However, the biological characteristics of CYV have not been sufficiently studied. In this study, we investigated the biological characteristics of CYV through rearing experiments and field surveys. No horizontal transmission between workers and broods was detected, and there were no significant differences in prevalence between castes. CYV was detected at all seven locations surveyed, with prevalence ranging from 60–95%. The high CYV prevalence across the host's distribution range indicates that the geographical distribution of CYV aligns with that of its host. These results suggest that CYV has spread throughout the host population, primarily through vertical transmission.

Camponotus yamaokai 病毒的流行、地理分布和传播途径

宿主与病毒之间的关系受多种因素的影响。一个潜在的因素是社会性。在蚂蚁等群居生物中，由于其独特的生态环境，宿主和病毒之间的相互作用可能与独居生物不同。我们以前从树栖蚂蚁山猫孔虫中分离到一种双链RNA toti样病毒，山猫孔虫病毒（CYV）。蚂蚁表现出一夫多妻的群体结构，有多个蚁后和巢内交配行为。这种独特的生态特征可能推动了与病毒的独特关系的演变。然而，CYV的生物学特性尚未得到充分的研究。本研究通过饲养试验和野外调查研究了CYV的生物学特性。未发现工蜂和雏鸟之间的水平传播，不同种姓之间的患病率无显著差异。在调查的所有7个地点均检测到CYV，流行率为60-95%。CYV在宿主分布范围内的高患病率表明，CYV的地理分布与其宿主的地理分布一致。这些结果表明，CYV主要通过垂直传播在宿主人群中传播。

期刊介绍： Archives of Virology publishes original contributions from all branches of research on viruses, virus-like agents, and virus infections of humans, animals, plants, insects, and bacteria. Coverage spans a broad spectrum of topics, from descriptions of newly discovered viruses, to studies of virus structure, composition, and genetics, to studies of virus interactions with host cells, organisms and populations. Studies employ molecular biologic, molecular genetics, and current immunologic and epidemiologic approaches. Contents include studies on the molecular pathogenesis, pathophysiology, and genetics of virus infections in individual hosts, and studies on the molecular epidemiology of virus infections in populations. Also included are studies involving applied research such as diagnostic technology development, monoclonal antibody panel development, vaccine development, and antiviral drug development.Archives of Virology wishes to publish obituaries of recently deceased well-known virologists and leading figures in virology.
