The use of phosphonoacetic (
PAA
) and phosphonoformic acid (PFA) as inhibitors of
African swine fever
virus (ASFV) replication in porcine monocytes/macrophages (MO) was investigated. At concentrations sufficient to inhibit replication, hemadsorption, and cytopathogenic damage by high inocula of ASFV, both antiviral agents were cytostatic and suppressed the DNA-synthetic growth response of porcine MO to the MO-specific colony-stimulating factor-1 (CSF-1).
PAA
and PFA inhibited ASFV-associated DNA-synthesis in the cytoplasm of infected swine MO. Using ASFV-specific monoclonal antibodies in immunebinding assays and in immunoprecipitation analysis of radiolabeled proteins of infected MO,
PAA
and PFA inhibited the synthesis of ASFV proteins of 13, 73, and 150/220 kDa, and caused a variable inhibition in the synthesis of a 12 kDa ASFV protein. These antiviral drugs, however, did not prevent the appearance of an early 32 kDa ASFV protein. The cytostatic and virus-suppressive effects of
PAA
and PFA could be reversed. ASFV resumed growth in infected MO cultures, if the cells maintained in medium with CSF-1 were removed from the antivirals before 1 week of drug exposure. With prolonged exposure to
PAA
or PFA (beyond 1 week), ASFV could not be recovered from infected MO cultures.
