In vitro and in vivo inhibition of myxoma virus by treatment with phosphonoacetic acid.

Abstract
Both myxoma and fibroma viruses were found to be sensitive in vitro to the effects of phosphonoacetic acid. Detectable myxoma virus replication was inhibited at a drug concentration of 100 micrograms/ml. Fibroma virus replication was inhibited at a concentration of 500 micrograms/ml. Because of this difference in sensitivity, myxoma virus was used to infect rabbits to test that efficacy of phosphonoacetic acid in the treatment of a systemic viral disease. Rabbits were given 400 mg kg-1 day-1 of phosphonoacetic acid subcutaneously in two injections. Phosphonoacetic acid-treated animals showed a reduction in the severity of disease. Neither serum viral antigen nor infectious virus could be detected. In phosphate buffered saline-treated animals both serum viral antigen and infectious virus were found. All animals treated with phosphate buffered saline died of myxomatosis.
