Ash和Riley,曾于1970年以彭亨丝虫皮下感染长爪砂鼠(Meriones unguiculatus)获得成功,以后的实验研究亦证实了这一发现。然而这种感染方式不能检获大量发育期幼虫和成虫。Ash还发现雄鼠较雌鼠易感,雄鼠的成虫发现率较低(10～20%),其中约70%的丝虫位于淋巴管,剩余30%多位于心、肺。大多数雄鼠于接种后60～100天内末梢血液中可查见微丝蚴。最近作者用腹腔感染一定数量刚成熟的雌、雄砂鼠,发现接种50～400条感染期幼虫,发育期幼虫和成虫的检获率较高(30～ Ash and Riley, who succeeded in subcutaneously infecting Meriones unguiculatus with penicillium worms in 1970, have also confirmed this finding in later experiments. However, this way of infection can not seize a large number of developmental larvae and adults. Ash also found that male rats were more susceptible than female mice, with a lower prevalence of adult adults (10-20%), with about 70% of them located in the lymphatic vessels and the remaining 30% in the heart and lungs. Most males in the 60 to 100 days after inoculation of peripheral blood can be found in microfilariae. Recently, the authors inoculated a certain number of mature female and male gerbils with abdominal cavity and found that the seizure rate of larvae and adults larvae and adults inoculated with 50 to 400 larvae was higher (30 ~
