Challenge was made after one month of immunization by vein. Re sults:The parasitemia of recombinant virus immunized monkey was 0.0 1%in first tw o days of post-challenge. No parasites were determined from third to 12th day. W hereas the parasitemia of control virus immunized-monkey and blank control monk ey rose progressively,went to 2.5%～6.0% at 6th～8th days of post-challenge, an d the t ime of parasitemia was 12～13 days.

结果： 在免疫后1个月攻虫，重组痘苗病毒免疫猴从第3天一直到第12 d的采血检查中均未发现疟原虫；非重组痘苗病毒免疫猴第3天后原虫感染率上升，第6天原虫感染率最高达到6.0%，而后原虫感染率逐渐下降，原虫持续时间为13天；空白对照猴第3天后原虫感染率也上升，第8天原虫感染率最高达到2.5%，而后原虫感染率逐渐下降，原虫持续出现时间为12 d。

Recombinant plasmid pSVH 7 DNA of avian influenza virus H7 subtype heamagglutinin gene was encapsulated with DC-chol/DOPE liposomes and PC/chol/SA liposomes separately. Two-week old SPF chickens were intramuscularly inoculated with 50 μ g/0.2ml of the liposome entrapped PSVH 7 DNA. Four-weeks later, each chicken was challenged with 0.1ml 〓 AIV . One week after the challenge, the secretion of the cloacas was collected and transfected to chicken embryos to isolate the virus. The virus was isolated from 6/6 of the control group, 1/6 of the naked DNA group, 1/6 of the PC/chol/SA entrapped DNA group and 0/6 of the DC-chol/DOPE liposome entrapped group. The HI antibody titers (log2) of the four groups were 6. 83±0.98, 7. 0±1. 26, 7. 83±1. 17 and 8. 00±0.89 respectively 1-week after challenge, and 8. 5±0.55, 8. 17±0.82, 8. 68±0.45 and 9. 33±0.54 respectively 2-week after challenge. The results showed that inoculation of liposome entrapped DNA significantly enhanced resistance to virosis in animals.

将含禽流感病毒H7亚型血凝素基因的重组质粒pSVH7用DC-chol阳离子脂质体和胆固醇／卵磷脂／十八胺脂质体包裹，免疫2周龄SPF鸡，4周后用同型禽流感病毒进行人工感染，1周后采集泄殖腔分泌物分离病毒，结果未免疫组6／6分离到病毒，裸质粒DNA免疫组1／6分离到病毒胆固醇／卵磷脂／十八胺脂质体包裹DNA免疫组1／6分离到病毒，DC-chol脂质体DNA免疫组没有分离到病毒（0／6）：人工感染后1周各组的HI抗体（Log2）分别为6.38±0.98，7.00±1.26，7.83±1.17，8.00±0.89，2周后为8.50±0.55，8.67±0.82，8.68±0.45，9.33±0.52，脂质体包裹组在同期均高于未免疫组和裸DNA免疫组，表明脂质体包裹质粒DNA免疫动物后，能增加动物对病毒感染的抵抗力和反应能力。
