摘要:

从传染病网络直报系统、医院等收集香格里拉市有既往病例,以本地感染病例为线索,选择患病率高的建塘、小中甸和格咱镇为调查点。根据2019—2021年香格里拉市三个乡镇传染源犬监测数据,行政村的犬粪抗阳性率分为高、中、低3层,每层随机抽取1~3个自然村作为研究点。2022年6月采用整群随机抽样法,每户采集1条犬粪样,随机采集路边无主犬/流浪犬粪样,每个乡(镇)调查犬200只以上,采用ELISA法犬粪抗原检测,家犬进行感染因素分析。共调查犬1 587只,阳性64只,阳性率为4.03%(64/1 587),其中家犬和无主犬或流浪犬棘球绦虫抗原阳性率分别为3.16%(35/1 107)和6.04%(29/480)(χ2 = 6.265,P < 0.05)。建塘、小中甸和格咱镇阳性率分别为4.60%(41/891)、3.18%(14/440)和3.52%(9/256),各乡镇棘球绦虫粪抗原阳性率差异有统计学意义(χ2 = 12.030,P < 0.05)。家犬感染以及其因素分析中,家犬公母阳性率分别是3.48%和2.68%,犬年龄组10周岁以上阳性率为4.11%,家犬性别和年龄组差异无统计学意义(χ2 = 1.184、2.384,均P > 0.05)。狼狗阳性率为5.56%,放养犬阳性率为36.36%,近3个月内没有驱虫犬阳性率为3.79%,投喂过病变脏器犬阳性率为17.20%。家犬品种、犬饲养方式和近3个月内是否驱过虫的犬和是否投喂过病变脏器的犬阳性率差异有统计学意义(χ2 = 15.431、49.121、5.291、65.391,均P < 0.05),Logistic回归分析显示4个因素均与犬棘球绦虫感染有显著关系。香格里拉市犬棘球绦虫感染率处于较高水平,应当着重强化对传染源犬的防控工作。

Abstract:

Data pertaining to previous echinococcosis cases and local cases were collected from the National Notifiable Disease Reporting System and hospitals in Shangri-La City, and Jiantang, Xiaozhongdian and Geza townships with high prevalence of echinococcosis were sampled as study areas. Based on the Results of surveillance on echinococcosis prevalence in dogs in three townships in Shangri-La City from 2019 to 2021, the positive rate of Echinococcus coproantigens was classified into three strata (high, moderate and low) in each administrative village, and one to three natural villages were randomly sampled from each stratum as study sites. In June 2022, a cluster random sampling method was employed, with one dog feces sample collected from each household, and fecal samples randomly collected from wayside ownerless or stray dogs, and more than 200 dogs were investigated in each township. Echinococcus coproantigen was detected in dogs using ELISA, and factors affecting the prevalence of Echinococcus infections were identified in domestic dogs. A total of 1 587 dogs were detected for Echinococcus coproantigens, with a positive rate of 4.03% (64/1 587), and the positive rates of Echinococcus coproantigens were 3.16% (35/1 107) in domestic dogs and 6.04% (29/480) in ownerless or stray dogs, respectively (χ2 = 6.265, P < 0.05). The positive rates of Echinococcus coproantigens were 4.60% (41/891), 3.18% (14/440), and 3.52% (9/256) in dogs in Jiantang, Xiaozhongdian, and Geza townships, respectively (χ2 = 12.030, P < 0.05). The positive rates of Echinococcus coproantigens were 3.48% in male domestic dogs and 2.68% female domestic dogs (χ2 = 1.184, P > 0.05), and the positive rate of Echinococcus coproantigens was 4.11% in dogs at ages of over 10 weeks, with no age-specific positive rate detected (χ2 = 2.384, P > 0.05). The positive rates of Echinococcus coproantigens were 5.56% in wolfhound dogs, 36.36% in free-range dogs, 3.39% without deworming during the latest three months, and 17.20% in dogs that had been fed diseased organs, respectively, and there were significant differences in the positive rates of Echinococcus coproantigens in domestic dogs in terms of dog breeds, ranging styles, deworming during the past three months, and feeding with diseased organs (χ2 = 15.431, 49.121, 5.291, 65.391, all P < 0.05). Logistic regression analysis showed that dog breeds, ranging styles, deworming during the past three months, and feeding with diseased organs were significantly associated with Echinococcus infections in dogs. The prevalence of Echinococcus infection is relatively high in dogs in Shangri-La City, and an emphasis on intensified management of dogs is recommended for echinococcosis prevention and control.
