Fecal egg counts for Kinnaura livestock and Asiatic Ibex in Pin Valley India

Disease cross-transmission between wild and domestic ungulates can have negative impacts on agricultural economies and wildlife conservation. Assessing how to reduce these impacts is key to maintaining people’s livelihoods while also conserving wild ungulate populations. In the trans-Himalayan region of Pin valley, migratory flocks of sheep and goats share pastures seasonally with the resident wild ungulate, Asiatic ibex (Capra sibirica), leading to the possibility of disease cross-transmission. We focused our work on gastro-intestinal nematode (GINs) as they are common determinants of health and fitness in wild and domestic ungulates. Using a parasite life cycle model that incorporated host movements and the effects of weather on infective larval availability, we investigated the transmission dynamics and evaluated potential interventions to attenuate infection pressure for both, the livestock and ibex. We found that although ibex used the pastures year-round, parasite eggs which they ...野生与家养有蹄类动物间的疾病交叉传播，会对农业经济与野生动物保护造成负面影响。评估如何缓解此类影响，是在保障民众生计的同时保护野生有蹄类种群的关键所在。在跨喜马拉雅区域的宾河谷（Pin valley），迁徙的绵羊与山羊群会与定居的野生有蹄类动物——亚洲羱羊（Asiatic ibex, Capra sibirica）——季节性共享牧场，这为疾病交叉传播提供了可能。本研究聚焦于胃肠道线虫（gastro-intestinal nematode, GINs），因其是影响野生与家养有蹄类动物健康与体质的常见致病因素。我们通过整合宿主移动性与天气对感染性幼虫可获得性影响的寄生虫生活史模型，探究了疾病传播动态，并评估了可降低家畜与亚洲羱羊感染压力的潜在干预手段。研究发现，尽管亚洲羱羊全年都在该牧场活动，但它们携带的寄生虫虫卵……
