A study was conducted to determine the prevalence of gastrointestinal parasites in a sample of urban dogs in Perth and the knowledge of their owners about the control and zoonotic transmission of these parasites. Faecal samples (421), collected from dogs originating from five sources, were examined by microscopy and questionnaires administered to dog owners and managers/owners of pet shops. The prevalence of gastrointestinal parasitism was higher in pet shop puppies (51%), than in dogs from refuges (37%), breeding kennels (32.7%), veterinary clinics (15.6%) and exercise areas (5.3%). Protozoa, in particular Giardia, were detected more frequently (22.1%) than helminth parasites. After adjusting for other factors with multiple logistic regression, puppies less than 6 months of age, dogs living in households with more than one dog, and dogs from refuges were significantly more likely to be parasitized. The prevalence of Giardia was found to be directly associated with the number of doses of anthelmintics given in a year, increasing 1.2 times for each dose administered. The majority of owners were aware of the potential risk to human health from canine helminths, however only one third were aware of the means of transmission to humans. It is concluded that veterinarians can play an important role in increasing the level of awareness of canine zoonotic parasites.
开展了一项研究，以确定珀斯城市犬样本中胃肠道寄生虫的流行情况，以及其主人对这些寄生虫的控制和人畜共患传播的了解程度。从五个来源的犬只采集了421份粪便样本，通过显微镜检查，并向犬主以及宠物店经理/店主发放问卷。宠物店幼犬的胃肠道寄生虫感染率（51%）高于来自收容所的犬（37%）、繁殖犬舍的犬（32.7%）、兽医诊所的犬（15.6%）和运动区域的犬（5.3%）。原生动物，尤其是贾第虫，比蠕虫寄生虫的检出频率更高（22.1%）。在通过多元逻辑回归对其他因素进行调整后，6个月龄以下的幼犬、生活在有多只犬的家庭中的犬以及来自收容所的犬被寄生的可能性显著更高。发现贾第虫的感染率与一年中给予驱虫药的剂量直接相关，每给药一剂增加1.2倍。大多数主人意识到犬类蠕虫对人类健康的潜在风险，然而只有三分之一的人了解传播给人类的途径。得出的结论是，兽医在提高对犬类人畜共患寄生虫的认识水平方面可以发挥重要作用。
