title: Sensitivity of equine herpesviruses 1 and 3 in vitro to a new nucleoside analogue, 9-[[2-hydroxy-1-(hydroxymethyl) ethoxy] methyl] guanine.
abstract: The following members of the Herpetoviridae family were tested to determine their sensitivities to the new antiviral drug, BIOLF-62: equine herpesvirus types 1 and 3, human herpesvirus types 1 and 2, swine herpesvirus, bovine herpesvirus type 4, feline herpesvirus, canine herpesvirus, and herpes simiae virus. Equine herpesviruses 1 and 3, human herpesviruses 1 and 2, and herpes simiae virus were all sensitive to BIOLF-62 at concentrations of less than 0.55 micrograms/ml. Equine herpesvirus types 1 and 3 were particularly sensitive, viral median effective dose (ED50) concentrations of the drug being only 0.033 and 0.16 micrograms/ml, respectively. Such high antiviral potency and low cell toxicity indicate that BIOLF-62 might be useful in the treatment of infected animals.
