【摘要】 依据Ag具有强烈杀毒抗菌的特性,开展对禽流感病毒的杀灭实验。通过TEM、XRD对载银硅藻土测定,反映了Ag以纳米状态负载于硅藻土的表面,没有产生化学反应。1g载银硅藻土能强烈吸附杀灭6mL溶液中的病毒液,血凝效价为零。洗脱上清液接种鸡胚的半致死数统计说明,0.35靏/mL的剂量对病毒有明显的杀灭作用,可进一步作饲料添加剂用于禽流感防治。对人体流感病毒交叉感染的防护隔离也是一个新的途径。更多还原

【Abstract】 Based on the high antibacterial performance of silver, the disinfection effect of AIV virus by Ag and Ag/diatomite was studied. The diatomite carrying silver was examined by TEM and XRD. The results showed that the diatomite carried nanometer silver particles and there was no chemical reaction between them. One gram of the composite can adsorb and disinfect virus in 6mL solution effectively and the figure of congealing blood was zero. The above clear liquid was inoculated to chicken embryos. The statistical figure of half death number of chicken embryo indicated that the dose of 0.35μg /mL Ag/diatomite could obviously disinfect the AIV virus. This composite is worth further studying as an additive to forage for prevention and control of chicken flu virus. It might be a new way to use the composite for protection of people from cross infection of flu viruses.更多还原
