Abstract

Sera (n = 781) from four African countries were used to determine the prevalence of herpes simplex virus type 2 (HSV-2) antibodies by using the HerpeSelect HSV-2 enzyme-linked immunosorbent assay (ELISA; Focus Technologies) and Western blotting (WB). Also, an HSV inhibition assay was developed to evaluate the discordant sample results between HerpesSelect and WB. The seroprevalence of HSV-2 ranged from 17% in the South African panel to nearly 70% in panels from Kenya, Uganda, and Zimbabwe. Overall, HerpeSelect was 100% sensitive and 88% specific compared to WB and 100% sensitive and 96% specific compared to the inhibition assay. There was 100% concordance among all three assays for samples from South Africa and Zimbabwe. The discordant results occurred in samples from Kenya and Uganda.

摘要

来自四个非洲国家的781份血清样本被用于通过使用HerpeSelect HSV - 2酶联免疫吸附测定法(ELISA;Focus Technologies公司)和蛋白质印迹法(WB)来确定2型单纯疱疹病毒(HSV - 2)抗体的流行率。此外,还开发了一种HSV抑制试验来评估HerpesSelect和WB之间结果不一致的样本。HSV - 2的血清流行率在南非样本组中为17%,而在肯尼亚、乌干达和津巴布韦的样本组中接近70%。总体而言,与WB相比,HerpeSelect的敏感性为100%,特异性为88%;与抑制试验相比,敏感性为100%,特异性为96%。来自南非和津巴布韦的样本在所有三种检测方法之间的一致性为100%。不一致的结果出现在来自肯尼亚和乌干达的样本中。
