spp. infections in wildlife populations have been linked to anthropogenic sources of infection and public health risk in a diversity of wildlife species and ecological locations worldwide. Quenda () remain in many urbanised areas of Perth, Western Australia, and can be gregarious in their interactions with humans and domestic animals. In a previous study, a high prevalence of spp. infection was identified amongst quenda trapped in urbanised environments and bushland in Perth, Western Australia. This study aimed to expand on that finding, by: identifying and estimating the prevalence of particular species of infecting quenda, and thus clarifying their anthropozoonotic/public health significance; identifying risk factors for spp. infection; and investigating putative associations between infection and indicators of ill health. spp. infections in Perth quenda are overwhelmingly of the host-adapted, non-zoonotic (apparent prevalence 22.2%; 95% CI 17.7-27.4%), indicating that quenda are not a substantial veterinary public health risk regarding this parasite genus. However, one case each of and genotype D were identified in quenda trapped in urbanised environments (apparent prevalences 0.4%; 95% CI 0.1-1.9%). In quenda, spp. infection is associated with infection and flea infection intensity, which may reflect host population density, or regarding spp., similar transmission pathways or synergistic interactions between these taxa within the host. spp. infection is not associated with the measured indicators of ill health in Perth quenda, but this finding is representative of only, given the apparent rarity of other sp. infections in this study.
野生动物种群中的寄生虫感染与人为感染源以及全球各种野生动物物种和生态环境中的公共卫生风险相关。袋狸（）仍生活在西澳大利亚珀斯的许多城市化地区，在与人类和家畜的互动中可能群居。在先前的一项研究中，在西澳大利亚珀斯城市化环境和丛林中捕获的袋狸中，发现寄生虫感染率很高。本研究旨在扩展该发现，具体包括：识别和估计感染袋狸的特定寄生虫物种的流行率，从而阐明它们的人畜共患病/公共卫生意义；识别寄生虫感染的风险因素；以及调查感染与健康不良指标之间的假定关联。珀斯袋狸的寄生虫感染绝大多数是宿主适应性的、非人畜共患的（表观流行率22.2%；95%置信区间17.7 - 27.4%），这表明就该寄生虫属而言，袋狸对兽医公共卫生风险不大。然而，在城市化环境中捕获的袋狸中分别鉴定出1例和基因型D（表观流行率0.4%；95%置信区间0.1 - 1.9%）。在袋狸中，寄生虫感染与感染和跳蚤感染强度相关，这可能反映宿主种群密度，或者就寄生虫而言，反映这些类群在宿主体内的相似传播途径或协同相互作用。寄生虫感染与珀斯袋狸中测量的健康不良指标无关，但鉴于本研究中其他寄生虫感染明显罕见，这一发现仅代表寄生虫。
