Ten viruses isolated from swabs and vesicular fluid collected from the teats of dairy cattle on 4 properties in Northern Victoria were identified as bovine herpes mammillitis (BHM) viruses by their physico-chemical and morphological properties and serological relationship to each other and a Scottish Strain of BHM virus. The viruses, isolated in bovine kidney and testicular cell cultures, produced cytopathic effects characterised by very large syncytia and eosinophilic intranuclear inculsion bodies. The intradermal inoculation of BHM virus into two cattle produced necrosis and ulceration of the skin of the teats about the area of inoculation and the development of serum neutralising antibody. After healing of the ulcers on day 37 after inoculation, the cattle were intravenously inoculated with corticosteroid for 6 days but BHM virus was not re-isolated from the teat skin or vaginal or nasal swabs.
