Abstract：
Dogs are common in Tonga, where they exist in a close relationship with humans as pets and guard dogs and often are free-roaming due to limited property fencing and the need to scavenge for food. Little is known about the health status of these dogs and the type and level of pathogens carried by them. In this study, blood and fecal samples were analyzed to identify the presence of endoparasites and determine packed cell volume (PCV) values for dogs in Tonga. The current data deficit in this area made it necessary to develop a methodology and collect preliminary data to assist with future research in Tonga. Fecal analysis revealed hookworm in 73% of dogs, primarily those 4-12 mo old. Hematologic evaluation revealed low to borderline low PCV in 87% of dogs. The zoonotic nature of some of the pathogens identified poses a public health risk, with a particular risk for children.
摘要：
狗在汤加很常见,在那里，它们作为宠物和看门狗与人类有着密切的关系，并且由于有限的财产围栏和需要寻找食物而经常自由漫游。人们对这些狗的健康状况以及它们携带的病原体的类型和水平知之甚少。在这项研究中,对汤加犬的血液和粪便样本进行分析,以确定体内寄生虫的存在,并确定填充细胞体积(PCV)值.目前这一领域的数据不足，因此有必要制定一种方法并收集初步数据，以协助汤加今后的研究。粪便分析显示73%的狗有钩虫，主要是4-12个月大的。血液学评估显示，87％的狗的PCV低至临界。一些确定的病原体的人畜共患性质构成了公共卫生风险，对儿童有特殊的风险。
