摘要
为了解湖南省长沙市宠物犬弓形虫感染状况,20172018年对长沙市宠物监测点的犬只抽样,采用间接酶联免疫方法进行弓形虫抗体检测。2017年共抽检血清707份,发现抗体阳性率为9.34%;2018年抽检血清711份,发现抗体阳性率为8.02%,较2017年稍微下降。从不同地区比较,天心区弓形虫感染率较高,均在13%以上;芙蓉区、岳麓区阳性率出现下降趋势,其中芙蓉区下降最快,从9.88%下降到4.79%,岳麓区从10.20%下降到6.98%;其他两区阳性率维持在7%~9%之间,相对平衡。对不同犬种、性别、年龄及季节进行比较分析发现,不同品种犬的弓形虫感染情况有差异,萨摩、中华田园、雪纳瑞、博美、柯基等犬种的阳性率相对偏高,在10%以上;犬弓形虫感染与性别关联性不大,差异不显著(P=0.086,>0.05);1岁以上犬的阳性率明显高于1岁以下犬,差异显著(P=0.012,<0.05);不同季节犬只的弓形虫抗体阳性率差异显著(P=0,<0.05)。调查表明:长沙市城区存在一定的犬弓形虫流行,整体呈下降趋势;犬弓形虫感染与年龄、季节相关,年龄越大阳性率越高,冬季更易感染。建议加强犬类管理,向饲养者普及相关饲养及弓形虫病预防知识,尤其是弓形虫感染严重地区;定期做好弓形虫检查和驱虫工作,重点关注感染率较高的犬种和1岁以上犬,尤其是冬季。本研究初步摸清了长沙市城区宠物犬弓形虫的感染程度及分布特点,为今后弓形虫病防控提供了数据支撑。
In order to recognize the infection status of toxoplasmosis in pets in Changsha City,Hunan Province,the dogs at monitoring stations were sampled to detect antibody against toxoplasmosis by indirect enzyme-linked immunosorbent Assay(ELISA)from 2017 to 2018.In 2017 and 2018,a total of 707 and 711 serum samples were respectively collected,the positive rates of antibody were 9.34%and 8.02%respectively,which was slightly lower in 2018;for different districts,the infection rate was higher in Tianxin District,which was above 13%,it trended to decrease in Furong District and Yuelu District,declined fastest from 9.88%to 4.79%in Furong District,and reduced from 10.2%to 6.98%in Yuelu District;the positive rate remained in the range of 7%to 9%in the rest two districts,which was relatively stable.It was found that,by comparing and analyzing different canine breeds,gender and age of dogs and seasons,the infection status of toxoplasmosis in various breeds was also different,the positive rates of Samoyed,Chinese Rural Dog,Schnauzer,Pomeranian and Corgi were relatively higher,all above 10%;the infection was not very relevant to gender,with slight difference(P=0.086,>0.05),the positive rate of dogs over one year old was obviously higher than that of those less than one year old,with obvious difference(P=0.012,<0.05);and the positive rate varied greatly in different seasons(P=0,<0.05).It was investigated that toxoplasmosis was prevalent to some extent in urban areas of Changsha City,and trended to decline as a whole;the infection was related to age and season,the older the age was,the higher the positive rate was,and it was more susceptible in winter.Some suggestions were hereby put forward,such as,strengthening management for dogs,popularizing relevant knowledge about breeding and prevention measures for toxoplasmosis to dog keepers,especially in areas with serious infection;regularly testing toxoplasmosis and deworming,and paying attention to dogs with high infection rate and those over one year old,especially in winter.In this paper,the infection status and distributions of toxoplasmosis in pet dogs in urban areas of Changsha City were preliminarily identified,which provided data support for prevention and control of toxoplasmosis in future.
