Role of bovine mammillitis virus towards preparation of an alternative vaccine against herpes simplex virus infections of human subjects.

Bovine mammillitis virus (BMV) cross-reacted in neutralization and radioimmune assay with herpes simplex virus (HSV) and pre-immunization with BMV protected against challenge by type 2 HSV. There was no evidence to suggest a pathogenic role for BMV as adjudged by a literature search or field enquiry and BMV specific antibody was not detected in 21 human sera or in four sera from personnel engaged in research with BMV; in addition there was no replication or antigen synthesis by BMV in explants of human tissue or cell lines of human origin. It is proposed that BMV might provide an alternative vaccine against HSV infections of human subjects.
