Abstract:
Three parapoxviruses which cause orf or related diseases in humans and animals and the orthopoxvirus, vaccinia virus, were tested for their in vitro sensitivity to cidofovir. The 50% inhibitory concentration for the three parapoxviruses was between 0.21 and 0.27 microg/ml and for vaccinia was 1.32 microg/ml. The selectivity index varied from 198 to 264 for the parapoxviruses and was 42 for vaccinia virus. Virus yield assays confirmed the ability of cidofovir to reduce ortho- and parapoxvirus replication. The efficacy of cidofovir against parapoxviruses justifies its evaluation as a candidate drug for the treatment of parapoxvirus infections in humans and animals.
