Antibody to herpes simplex virus (HSV) plus complement destroyed HSV-infected cells but did not stop the spread of the infection. Studies on the relationship between the time of appearance of viral antigens on the cell surface, immunological destruction of the cells by antiviral antibody and complement, and transfer of the virus to adjacent cells showed that the virus spread from infected to uninfected cells before the infected cells were susceptible to immunological destruction. Incubation of infected monolayers with leukocytes, however, stopped the spread of the virus by nonspecifically damaging both infected and uninfected cells and by presumably breaking intercellular bridges. When leukocytes were removed from infected monolayers, viral plaques developed. If, however, antiviral antibody and complement were added to monolayers before the leukocytes were removed, the development of plaques was prevented. These findings suggest that both antibody and leukocytes are needed to cure HSV infections.
