摘　　要：为了解北京地区近年来犬胃肠道寄生虫流行情况,本试验收集了2018年1月—2021年12月在中国农业大学教学动物医院检验中心进行检查的9812例病例的犬粪便常规检查结果,对粪便中胃肠道寄生虫的种类、数量、感染率、混合感染情况和感染患犬的年龄分布进行统计分析,并将该统计结果与本院2002年3152例病例的调查结果进行比较。结果显示,2018—2021年的犬胃肠道寄生虫感染率依次为7.96%、6.15%、7.43%和3.55%,相较于2002年(22.24%)均极显著降低(P<0.01),优势寄生虫种类从蛔虫转变为贾第鞭毛虫;2018—2021年的犬胃肠道寄生虫混合感染病例数占感染病例总数的比率依次为11.88%、17.88%、23.58%和12.82%,均高于2002年的7.85%,且近4年主要为贾第鞭毛虫和毛滴虫混合感染;近4年,6月龄及以内的幼年犬感染率极显著高于其他年龄段犬的感染率(P<0.01)。结果表明,犬胃肠道各类寄生虫的感染率与定期驱虫密切相关,做好幼年犬的驱虫工作极为重要。To understand the recent prevalence of canine gastrointestinal parasites in Beijing,this study collected the results of routine fecal examinations from 9812 cases of dogs examined at the Examination Center of China Agricultural University Veterinary Teaching Hospital from January 2018 to December 2021.The types,quantities,infection rates,mixed infection status,and age distribution of infected dogs were statistically analyzed,and the results were compared with the survey results of 3152 cases in our hospital in 2002.The results showed that the infection rates of canine gastrointestinal parasites from 2018 to 2021 were 7.96%,6.15%,7.43%,and 3.55%,respectively,extremely significantly lower(P<0.01)than that in 2002(22.24%),with the dominant parasite types shifting from Ascarid to Giardia.The proportion of cases with mixed infections of canine gastrointestinal parasites from 2018 to 2021 accounted for 11.88%,17.88%,23.58%,and 12.82%of the total infected cases,respectively,all higher than the 7.85%in 2002,and in recent 4 years,the main combination of mixed infections was Giardia and Trichomonad.In the past four years,the infection rate of dogs under six months of age was extremely significantly higher than that of dogs in other age groups(P<0.01).The results indicate that the infection rates of various canine gastrointestinal parasites are closely related to regular deworming,and it is essential to do a good job of deworming in young dogs.
