由于殖民地的同质性，以及其成员之间的紧密接近和广泛的相互作用，社会有机体特别容易受到病原体的攻击。然而，这些群体的社会组织也提供了在殖民地内提供防止病原体传播的有效屏障的潜力。社会性昆虫及其复杂的群体组织为发展和检验这一假说提供了理想的模型系统。虽然菌落组织的不同元素通常被认为是人机工程学选择的产物，在本文中，我们解决了相同的元素如何影响病原体的传播。通过建立一个简单的模型，我们探讨了群体组织、劳动分工、相互作用网络和群体人口统计学三个参数如何影响病原体的传播。我们发现，个体之间的劳动分工的异质性对殖民地中感染的传播几乎没有影响，并且这种情况与所有个体都是同质的情况没有区别。然而，劳动分工，加上交互网络的异质性和人口统计学时间表，减少了感染的传播。(C)2002爱思唯尔科技有限公司。保留所有权利。
Social organisms are especially vulnerable to pathogens due to the homogeneity of the colony, and the close proximity and extensive interactions among its members. However, the social organization of these groups also offers the potential to provide an effective barrier against the transmission of pathogens within the colony. Social insects with their elaborate colony organizations provide an ideal model system to develop and test this hypothesis. While the different elements of colony organization are generally assumed to be products of ergonomic selection, in this paper we address how the same elements could influence the transmission of pathogens. By developing a simple model, we explore how three parameters of colony organization, division of labor, interaction network and colony demography could influence the transmission of pathogens. We find that heterogeneity among individuals in terms of division of labor alone has little effect on the spread of an infection in the colony and the scenario is indistinguishable from one in which all the individuals are homogeneous. However, division of labor, combined with heterogeneity in the interaction network and demographic schedules reduce the spread of an infection. (C) 2002 Elsevier Science Ltd. All rights reserved.
