英国国家蜜蜂单位的检查员被要求在2007-2008年针对英格兰和威尔士的问题养蜂场进行病原体筛查和菌落强度测量。健康的菌落被包括在采样中，以提供连续的健康状况。共筛选出406份成蜂样品，产生7种病毒，1种细菌，2种微孢子虫病原体和1种体外寄生虫（Acarapis woodi）。另外，对108份蜂苗样品进行了病毒分离，共分离到4种病毒。病毒流行程度从常见（畸形翅病毒、黑皇后细胞病毒）到完全不存在（以色列急性麻痹病毒）不等。当蜂群被迫分成两类，强或弱，弱的蜂群在成年蜜蜂中含有更多的病原体。在所观察到的病原体中，只有变形翅病毒能够预测菌落强度。这种影响是负面的，使得对变形翼病毒检测呈阳性的菌落可能具有更少的蜂冠或育雏。这项研究构成了英国微孢子虫的第一个记录。这些结果有助于越来越多的证据将病原体与蜜蜂健康状况不佳联系起来。
Inspectors with the UK National Bee Unit were asked for 2007-2008 to target problem apiaries in England and Wales for pathogen screening and colony strength measures. Healthy colonies were included in the sampling to provide a continuum of health conditions. A total of 406 adult bee samples was screened and yielded 7 viral, 1 bacterial, and 2 microsporidial pathogens and 1 ectoparasite (Acarapis woodi). In addition, 108 samples of brood were screened and yielded 4 honey bee viruses. Virus prevalence varied from common (deformed wing virus, black queen cell virus) to complete absence (Israeli acute paralysis virus). When colonies were forced into one of two classes, strong or weak, the weak colonies contained more pathogens in adult bees. Among observed pathogens, only deformed wing virus was able to predict colony strength. The effect was negative such that colonies testing positive for deformed wing virus were likely to have fewer combs of bees or brood. This study constitutes the first record for Nosema ceranae in Great Britain. These results contribute to the growing body of evidence linking pathogens to poor honey bee health.
