1966年新疆巴楚县出血热病研究报告 Ⅱ.新疆巴楚出血热病原学的初步研究

Report of Investigation on Hemorrhagic Fever in Bachu County, Xinjiang in 1966 Ⅱ. A Preliminary Study on Etiology of Hemorrhagic Fever in Bachu

1966年4~5月从新疆巴楚县阿克沙克马拉勒地区的出血热病人急性期血液和死亡病例的肝、脾、肾及淋巴结等脏器组织标本和牧场中采集的亚洲璃眼蜱成虫标本接种4日龄以内的新生小鼠(乳鼠),结果共分离出14株病毒。标本经脑内和腹腔联合接种乳鼠后6~10天之间出现典型症状,包括:惊跳、弓背、痉挛、继之出现迟纯、软弱、平衡失调、侧卧、拒乳、皮肤苍白而死亡。在乳鼠中连续传代3次后,潜伏期缩短为5天,发病规律,可稳定传代。乳鼠脑组织中的病毒滴度可达6.78logLD50/0.01mL。新生金地鼠在接种急性期病人血液标本后可出现症状和死亡。新生大白鼠用从病人分离的病毒进行脑内和腹腔接种后出现典型症状并死亡。豚鼠在腹腔接种病人急性期血液标本后出现轻度症状。取其心血接种乳鼠后可使乳鼠发病。在有症状和无症状的豚鼠血清中均可测出较高滴度的补体结合抗体。1岁龄绵羊在皮下接种10%感染乳鼠脑悬液后仅出现轻度不适,但用此绵羊的血液接种乳鼠可使乳鼠发病死亡。绵羊的病毒血症至少可持续6天。通过绵羊的病毒在乳鼠中的潜伏期缩短为4天,滴度升高,10-6稀释度可使乳鼠全部死亡。病毒可通过蔡氏滤器EK滤板。可被低浓度甲醛灭活。1/10氯仿、20%乙醚在室...

Fourteen strains of the virus were isolated by inoculation combined with intracerbral and intrapertoneal route in suckling mice less than 4 days after borne, from the blood samples of patients with acute phase of hemorrhagic fever and the samples of brain, liver, spleen and lymphatic nodes of fatal cases and the samples of adult ticks of Hyalomma asiaticum from pastureland in Aksakmaral area of Bachu County in the period of April-May, 1966. The typical symptoms in suckling mice occurred within 6-10 days aft...
