To determine whether hydatidosis occurs in cattle bred in the northern region of the Northern Territory.
A survey utilising two stage sampling was designed to provide 95% confidence of detecting hydatids in cattle with a herd prevalence of 10% and animal prevalence of 10%.
For a 1 year abattoir killing season, lesions from the liver and/or lung were collected from 4348 cattle being slaughtered at a Northern Territory abattoir and examined for hydatid cysts. The origin of cattle was established through identification of the brand.
Sample sizes of 41 or more Northern Territory bred cattle were achieved for each of 29 properties. No hydatid cysts were found in cattle bred in the northern region of the Northern Territory.
This study provides evidence that a cycle of hydatid transmission does not occur in the northern region of the Northern Territory.
确定在北领地北部地区饲养的牛是否会发生包虫病。
采用两阶段抽样的调查旨在以95%的置信度检测牛群患病率为10%且个体患病率为10%的牛中的包虫。
在北领地一家屠宰场为期1年的屠宰季中,从4348头被屠宰的牛身上收集肝脏和/或肺部的病变,并检查是否有包虫囊肿。通过识别烙印确定牛的来源。
29个养殖场中每个养殖场的北领地本地饲养牛的样本量均达到41头或更多。在北领地北部地区饲养的牛中未发现包虫囊肿。
本研究提供了证据,表明北领地北部地区不存在包虫传播循环。
