蜜蜂丝状病毒（AmFV）是蜜蜂的一种大型双链DNA病毒，但其与其他寄生虫的关系及其流行情况尚不清楚。为了监测自然条件下AmFV肠道定植的动态，我们分析了三个蜂群在羽化后不同时间的个体蜜蜂。还记录了小孢子虫和锥虫以及五种常见的蜜蜂RNA病毒的流行率和载量。结果表明，高比例的蜜蜂在出蛹后的第一周感染AmFV(75%)，并且AmFV DNA水平保持不变。在小孢子虫中也观察到类似的模式，而锥虫似乎需要更多的时间来定植肠道。这三种感染之间没有发现显著的关联，但AmFV和RNA病毒之间观察到显著的正相关。同时，对法国和瑞典的蜜蜂工蜂进行了AmFV患病率评估。数据表明，AmFV几乎无处不在，而且似乎不遵循季节性模式，尽管在春季检测到较高的病毒载量。AmFV在冬蜂中也有较高的流行率，但对蜂群越冬无明显影响。
Apis mellifera filamentous virus (AmFV) is a large double stranded DNA virus of honey bees, but its relationship with other parasites and prevalence are poorly known. We analyzed individual honey bees from three colonies at different times post emergence in order to monitor the dynamics of the AmFV gut colonization under natural conditions. Prevalence and loads of microsporidia and trypanosomes were also recorded, as well as five common honey bee RNA viruses. The results show that a high proportion of bees get infected with AmFV during the first week post-emergence (75%) and that AmFV DNA levels remained constant. A similar pattern was observed for microsporidia while trypanosomes seem to require more time to colonize the gut. No significant associations between these three infections were found, but significant positive correlations were observed between AmFV and RNA viruses. In parallel, the prevalence of AmFV in France and Sweden was assessed from pooled honey bee workers. The data indicate that AmFV is almost ubiquitous, and does not seem to follow seasonal patterns, although higher viral loads were significantly detected in spring. A high prevalence of AmFV was also found in winter bees, without obvious impact on overwintering of the colonies.
