变形翅病毒是一种新出现的蜜蜂病原体，在过去的40年里在全球范围内出现。当由寄生的瓦螨传播时，它与整个北半球数百万个殖民地的崩溃有关。然而，尽管在南半球存在这种螨虫，但被感染的蜂群仍然存活下来。这项研究调查了南非登革热病毒A、B和C型及其病毒载量的流行情况，并将研究结果与巴西、英国和美国的最新数据进行了比较。我们发现DWV-B是南非最流行的基因型，尽管DWV总病毒载量(2.8E+07)显著低于北半球的发现(2.8E+07 vs.2.7E+10，p>；0.00001)，与巴西的发现(5e+06，p=0.13)没有显著差异。病毒载量的差异可以解释为巴西和南非对尘虫的抵抗力，因为含有高病毒载量的蠕虫感染细胞被蜜蜂清除，从而降低了蜂群的病毒负担。在北半球的绝大多数蜜蜂中，这种行为的发育程度要低得多。
Deformed wing virus (DWV) is an emerging honeybee pathogen that has appeared across the globe in the past 40 years. When transmitted by the parasitic varroa mite, it has been associated with the collapse of millions of colonies throughout the Northern Hemisphere. However, despite the presence of the mite in the Southern Hemisphere, infested colonies survive. This study investigated the prevalence of DWV genotypes A, B and C along with their viral loads in South Africa and compared the findings with recent data from Brazil, the UK and the USA. We found that DWV-B was the most prevalent genotype throughout South Africa, although the total DWV viral load was significantly lower (2.8E+07) than found in the Northern Hemisphere (2.8E+07 vs. 2.7E+10, p > 0.00001) and not significantly different to that found in Brazil (5E+06, p = 0.13). The differences in viral load can be explained by the mite resistance in Brazil and South Africa, since mite-infested cells containing high viral loads are removed by the bees, thus lowering the colony's viral burden. This behaviour is much less developed in the vast majority of honeybees in the Northern Hemisphere.
