当严重感染的国内宿主与密切相关的野生动物种群相互作用时，可能发生病原体传播或“溢出”。用于温室授粉的商业生产的熊蜂通常比野生熊蜂具有更高水平的各种病原体。当商业蜜蜂逃离温室并与附近花朵上的野生蜜蜂相互作用时，这些病原体可能会传播给野生蜜蜂。我们研究了四种病原体在野生熊蜂种群的流行，在附近和远离商业温室在加拿大南部安大略。商业温室附近收集的大黄蜂更频繁地感染这些病原体能够在花（Crithidia bombi和微孢子虫bombi）比蜜蜂收集在远离温室的网站。我们认为，从商业野生蜜蜂的病原体的溢出是最有可能的原因，这种模式，我们讨论了这种溢出熊蜂保护的影响。(c)2005爱思唯尔有限公司保留所有权利。
Pathogen spread or 'spillover' can occur when heavily infected, domestic hosts interact with closely-related wildlife populations. Commercially-produced bumble bees used in greenhouse pollination often have higher levels of various pathogens than wild bumble bees. These pathogens may spread to wild bees when commercial bees escape from greenhouses and interact with their wild counterparts at nearby flowers. We examined the prevalence of four pathogens in wild bumble bee populations at locations near and distant to commercial greenhouses in southern Ontario, Canada. Bumble bees collected near commercial greenhouses were more frequently infected by those pathogens capable of being transmitted at flowers (Crithidia bombi and Nosema bombi) than bees collected at sites away from greenhouses. We argue that the spillover of pathogens from commercial to wild bees is the most likely cause of this pattern and we discuss the implications of such spillover for bumble bee conservation.
