Abstract

A synthetic peptide corresponding to a part of the virus protein 1-virus protein 2 overlapping region of human parvovirus B19 was used in an indirect enzyme-linked immunosorbent assay. Antibodies of the immunoglobulin (Ig) M class were measured in serum samples from patients with erythema infectiosum and controls. In comparison with an IgM assay using native B19 viral antigen, the peptide antigen assay was 92% sensitive and 87% specific. B19 IgM reactivities were seen in a limited number of children with other viral diseases. Specific IgM reactivities to short synthetic viral peptides have previously been reported only with Epstein-Barr virus. Since other sources of viral antigen are limited, the peptide antigen assay may be a useful alternative for the diagnosis of B19-associated disease in human beings.

摘要

一种对应于人类细小病毒B19病毒蛋白1-病毒蛋白2重叠区域一部分的合成肽被用于间接酶联免疫吸附测定。在传染性红斑患者和对照的血清样本中检测免疫球蛋白(Ig)M类抗体。与使用天然B19病毒抗原的IgM测定相比,肽抗原测定的敏感性为92%,特异性为87%。在少数患有其他病毒疾病的儿童中也观察到了B19 IgM反应性。以前仅报道过针对爱泼斯坦-巴尔病毒的短合成病毒肽的特异性IgM反应性。由于其他病毒抗原来源有限,肽抗原测定可能是诊断人类B19相关疾病的一种有用替代方法。
