摘要
为了解新疆昭苏县马匹体表蜱虫和周围游离蜱虫携带马梨形虫情况及其之间流行关系,于2016年4―7月份,分别采集马匹血液、相应马体表携带蜱虫和周围牧场的蜱虫,经PCR检测总携带梨形虫率分别为93.9%(31/33),15.8%(6/38),3.4%(6/175);对所采集的蜱虫进行形态学鉴定,结果分别为草原革蜱、森林革蜱和边缘革蜱;3种革蜱占马体表蜱虫总数的比率和带虫率分别为52.6%(7.9%),44.8%(7.9%),2.6%(0.0%),占牧场游离蜱虫总数的比率和带虫率分别为56.0%(2.3%),43.4%(1.1%),0.6%(0.0%);根据统计学分析,马匹年龄与携带梨形虫及其媒介蜱之间差异显著(P<0.05),马携带蜱虫数量与马源性、蜱源性泰勒虫的感染三者之间均存在显著性差异(P<0.01)。因此,新疆昭苏地区马梨形虫的流行与马匹年龄、带虫媒介蜱虫的数量、种类等因素有关联性。
This study investigated the epidemic of equine piroplasmoses(EP)and its influences factor in Zhaosu,Xinjiang.The horse blood and tick samples were collected while tick samples were collected from horse skin surface and grasslands from April to July,2016.The EP infection rates detected by PCR were 93.9%(31/33),15.8%(6/38)and 3.4%(6/175)and three species of ticks(D.nuttalli,D.silvarum,and D.marginatus)were identified by morphological methods.The rate of ticks and infestation in skin surface were 52.6%(7.9%),44.8%(7.9%),and 2.6%(0.0%),respectively.And the rate of ticks and infestation were 56.0%(2.3%),43.4%(1.1%),and 0.6%(0.0%)in grasslands.According to the statistical analysis,there was a significant difference between the age of horses,tick species,and infections of piroplasmosis(P<0.05).Furthermore,a significant difference was identified between the number of ticks from horses,horses and ticks infected with T.equi(P<0.01).Therefore,the epidemic of the EP is directly related to the age of horses,the number of EP-carrying vector ticks and its species in Zhaosu,Xinjiang.
