Feral goats, (Bovidae), currently occur across 28% of Australia, and are found in all states and territories as well as some offshore islands. Feral goats are harvested for live export or processed as game meat, with feral goats making up approximately 90% of goats sent to slaughter in Australia. Nymphs of the pentastomid parasite, , are common parasites of goats elsewhere in the world, where they cause Halzoun or Marrara disease in humans through the consumption of nymphs in raw or semi-cooked edible offal. Despite being commonly encountered in cattle at slaughter in Australia, nymphs have never been reported from feral goats in Australia. Goats at slaughter, however, commonly show infections of lymph nodes, the majority of which are diagnosed as caseous lymphadenitis caused by bacteria, although a small number have no known aetiology. Examination of 33 feral goats from locations in New South Wales and South Australia found a sp. nymph encased in the mesenteric lymph node of one goat from the Cooma region of New South Wales. The potential risk of transmission of sp. to humans and other domestic animals is discussed. This study has highlighted the importance of continued surveys of feral animals for infection with parasites, especially as their distribution changes.
野生山羊(牛科)目前分布在澳大利亚28%的地区,在所有州和领地以及一些近海岛屿都有发现。野生山羊被捕获用于活体出口或作为野味进行加工,在澳大利亚送往屠宰场的山羊中,野生山羊约占90%。五口吸虫寄生虫的若虫是世界其他地方山羊的常见寄生虫,通过食用生的或半熟的可食用内脏中的若虫,它们会在人类中引发哈尔宗病或马拉拉病。尽管在澳大利亚屠宰的牛中经常发现若虫,但澳大利亚的野生山羊从未有过相关报告。然而,屠宰的山羊通常会出现淋巴结感染,其中大多数被诊断为由细菌引起的干酪性淋巴结炎,尽管少数感染病因不明。对来自新南威尔士州和南澳大利亚州各地的33只野生山羊进行检查后,在新南威尔士州库马地区的一只山羊的肠系膜淋巴结中发现了一种五口吸虫若虫新种。文中讨论了该五口吸虫新种传播给人类和其他家畜的潜在风险。这项研究凸显了持续调查野生动物寄生虫感染情况的重要性,尤其是在其分布发生变化时。
