项目摘要

"Animal movement is a major defence against infectious diseases, by avoiding contaminated areas, but has been applied haphazardly within farmed environments. Constraining grazing ruminants within fields with movements between them geared towards grass utilization often provides ideal conditions for parasite transmission, leading to excessive use of chemical anthelmintics that are now failing due to drug resistance. This project will re-imagine ruminant movements within farm environments, inspired by the migration patterns of free-living and extensively farmed ungulates, in order to identify strategies that both decrease disease transmission on future farms and allow for efficient resource use.The project will focus initially on gastrointestinal nematodes using existing computer models backed up by field sampling of selected systems, before adding in prediction and measurement of coinfections with bacterial pathogens. This will address the potential for increased microparasite transmission risk should a change towards highly mobile grazing systems on limited land area entail increased herd density. The project will address this issue at a range of scales to achieve strategic insights as well as co-production of practical disease control strategies with farmers. Training will be provided in mathematical modelling and computational biology, laboratory diagnostic parasitology, microbiology and stakeholder engagement."

“动物运动是预防传染病的主要手段，可以避免污染地区，但在养殖环境中却被随意应用。将放牧反刍动物限制在田间，使它们之间的运动适合于草的利用，这通常为寄生虫传播提供了理想的条件，导致过度使用化学驱虫剂，而化学驱虫剂现在由于耐药性而失效。该项目将重新设想反刍动物在农场环境中的运动，灵感来自自由生活和广泛养殖的有蹄类动物的迁移模式，以确定既减少未来农场的疾病传播又允许有效利用资源的策略。该项目将首先利用现有的计算机模型，通过选定系统的实地采样，然后再加入对细菌病原体合并感染的预测和测量。这将解决微寄生虫传播风险增加的可能性，如果在有限的土地面积上向高度移动的放牧系统转变，会导致畜群密度增加。该项目将在一系列规模上解决这一问题，以实现战略见解，并与农民共同制定实用的疾病控制战略。将提供数学建模和计算生物学、实验室诊断寄生虫学、微生物学和利益攸关方参与方面的培训。"
