贵州省牛血孢子虫病疫源地宿主动物的研究 2.关于野生动物宿主的自然感染调查和人工感染试验

一、在猎获的26只野禽和15只野生动物中均未查见有血孢子虫的存在,但存野兔体上发现有传播双芽焦虫的微小方头蜱的寄生。因此野兔在该种血孢子虫病的流行上起着保存传播者的作用,在防制血孢子虫病时应加以注意。二、人工感染33只试验动物,结果均是阴性。三、本文工作结果维持前文中的结论:所研究的疫源地是一种家畜专有疾病的疫源地。

STUDIES ON THE HOST ANIMA LS OF THE KWEICHOW NIDUS OF BOVINE HAEMOSPORIDIASIS 2. ON THE NATURAL INFECTION OF WILD HOST ANIMALS AND SOME ARTIFICIAL INFECTIONS

1.No haemospor idium was found on 26 wild birds and 15 wild animals captured but ticks identified as Boophilus microplus (Canestrini, 1887) and having been recognized as the vector of piroplasma bigeminum (Smith et kilborne, 1893)in Kweichow province, were found on wild rabbits. Hence,wild rabbits may be considered as the reservoir animals of the vector of piroplasmosis and are worthy to be on the alert as far as the control against that haemosporidiasis is coneer ned. 2.33 experimental animals were infected artificially with all he,at ire results. 3.Findings reported in this paper maintains our previous conclusion that the nidus concer,ned is one of the diseases specific to domestic animals.
