最佳条件下的回收细胞培养衍生的水痘带状疱疹病毒(VZV)。在测试的细胞中,人胚肺成纤维细胞是最敏感的。检查储存和处理程序,以确定VZV在病毒转运培养基中的稳定性。当初始VZV滴度较高(2 × 10(4)PFU/ml)时,40%的VZV在室温下存活24小时,75%的VZV在4 ℃下存活这么长时间。在较低的初始VZV滴度(小于2 × 10(3)PFU/ml)下,回收率低5- 10倍。影响VZV回收的其他因素包括在-20摄氏度下冷冻、使用棉花或藻酸钙拭子以及过滤以去除细菌污染物。所描述的组织培养方法用于重建实验中,以证明VZV可以从实验室外套或人皮肤(输入VZV的0.1至0.3%)或从听诊器(输入VZV的19%)中回收,最迟在接种后30分钟。在使用最佳VZV恢复程序的临床试验中,76%的带状疱疹患者在首次培养时产生VZV,60%的患者在另外48小时内保持培养阳性。
Optimal conditions are described for the recovery of cell culture-derived varicella-zoster virus (VZV). Of the cells tested, human embryonic lung fibroblasts were the most sensitive. Storage and handling procedures were examined to determine the stability of VZV in viral transport medium. When the initial VZV titer was high (2 X 10(4) PFU/ml) 40% of the VZV survived room temperature for 24 h and 75% of the VZV remained viable for this long at 4 degrees C. Recovery was 5- to 10-fold less at lower initial VZV titers (less than 2 X 10(3) PFU/ml). Other factors which influenced VZV recovery included freezing at -20 degrees C, the use of cotton or calcium alginate swabs, and filtration to remove bacterial contaminants. The tissue culture methods described were used in a reconstruction experiment to demonstrate that VZV could be recovered from a laboratory coat or human skin (0.1 to 0.3% of input VZV) or from a stethoscope (19% of input VZV) as late as 30 min after inoculation. During a clinical trial using optimal VZV recovery procedures, 76% of the patients with herpes zoster yielded VZV when first cultured, and 60% remained culture positive for an additional 48 h.
