Intratypic variations in neutralizable epitopes among herpes simplex virus type 2 isolates.
Intratypic variation among 94 isolates of herpes simplex virus type 2 (HSV-2) was investigated using 4 different monoclonal antibodies (MAbs). By neutralization test, these MAbs appeared to be directed to at least 2 distinct epitopes on the viral glycoprotein D (gD), i.e., 6G6.G9 and 6E8.F11 which did not require complement (C-MAb) and gD-105 and gD-110 whose neutralizing activities could be enhanced by complement (C+MAb). The C-MAb pairs each separately could detect significant intratypic variations among the isolates. Whether these variations also existed in the gD epitope(s) recognized by C+MAbs remains to be elucidated. The results suggested that intratypic variation occurred on at least one of the neutralizable (thus related to protective immunity) epitopes on gD of HSV-2.
