inhibition by rifampin of african swine fever virus replication in tissue culture.vaccinia virus and african swine fever virus are deoxyribonucleic acid viruses of cytoplasmic origin. the fact that rifampin inhibits the replication of the former virus led to an investigation of its effect on african swine fever virus. the virus used was cytopathogenic to a pk-15 cell line, hemadsorbing in pig leukocyte cultures and lethal to pigs. rifampin clearly inhibited the multiplication and cytopathogenicity of the virus in pk-15 cells. there was a 1- to 5-log reduction in virus titer d ...19715154875

mechanism of synthesis of vaccinia virus double-stranded ribonucleic acid in vivo and in vitro.the synthesis of vaccinia virus double-stranded ribonucleic acid (rna) in infected hela cells was sensitive to actinomycin d, suggesting that a deoxyribonucleic acid dependent reaction is involved. some double-stranded rna was made in the presence of cytosine arabinoside in infected cells. double-stranded and complementary rna were synthesized in vitro by using vaccinia cores. these two observations indicate that some of the double-stranded rna is read from "early" genes. the double-stranded rna ...19715543434

effect of rifamycins and related antibiotics on the deoxyribonucleic acid-dependent ribonucleic acid polymerase of vaccinia virus particles.a number of compounds related to rifampin which act as expected in the escherichia coli system have been tested for their ability to inhibit the vaccinia particle deoxyribonucleic acid-dependent ribonucleic acid (rna) polymerase in vitro. some compounds are inactive even at concentrations of 500 mug/ml, others are able to produce partial inhibition, and others strongly inhibit the enzyme activity at 150 mug/ml or less. the inhibition, where present, operates immediately but appears to be at leas ...19714940241

antiviral activity of polyribocytidylic acid in cells primed with polyriboinosinic acid.separate administration of polyribocytidylic acid [poly(rc)] and polyriboinosinic acid [poly(ri)] to cell cultures in vitro resulted in an antiviral activity identical to or greater than that resulting from addition of the poly(ri) * poly(rc) complex. priming of cells with poly(ri), followed by treatment with poly(rc), gave a consistently greater antiviral activity than poly(ri) * poly(rc) itself. this priming effect was obtained in several cell cultures challenged with different viruses. in viv ...19714325867

use of disposable micro tissue culture plates for antiviral and interferon induction studies.a reproducible test system requiring small amounts of test compound was developed for evaluating antiviral and interferon-inducing activity. in the antiviral experiments, kb cells were grown in disposable polystyrene microplates covered with a standard domestic plastic wrap. viruses used in the system were types 1 and 2 herpes simplex virus, vaccinia virus, type 3 adenovirus, myxoma virus, pseudorabies virus, type 3 parainfluenza virus, types 1a and 13 rhinovirus, vesicular stomatitis virus, cox ...19714332040

system of double infection between vaccinia virus and mengovirus.when l cells are simultaneously infected with vaccinia virus and mengovirus, double interference in the replication of both viruses is observed. superinfection of vaccinia virus-infected cells by mengovirus during the first 5 hr of infection reduces vaccinia virus yields to between 1 and 3% of controls. the yields of mengovirus are reduced to between 1 and 16% of controls, depending upon the time of superinfection. the replication of vaccinia deoxyribonucleic acid is not inhibited by mengovirus; ...19714330362

inactivation of influenza and other viruses by a mixture of virucidal compounds.a mixture of benzalkonium chloride, triton x100, and citric acid (resiguard f) had a marked virucidal effect on lipid-containing deoxyribonucleic and ribonucleic acid viruses, such as vaccinia virus, herpesvirus, and influenza virus. adenoviruses and picornaviruses were more resistant to inactivation. electron microscopy showed that influenza particles became aggregated in the presence of resiguard f and that the outer fringe of hemagglutinin and neuraminidase spikes seen in control virus prepar ...19714102573

inhibition of poxvirus maturation by rifamycin derivatives and related compounds.the effect of a number of rifamycin derivatives and related compounds on the reversibility of the rifampin-induced virus maturation block was studied by using bhk-21 cells infected with vaccinia virus. all of the derivatives of 3-formyl rifamycin sv maintained this block, the required concentration varying from 100 to 1,000 mug/ml. these compounds vary only in the nature of the side-chain attached to the 3c atom on the naphthohydroquinone moiety; no obvious correlation between the nature of this ...19714105118

similar effect of rifampin and other rifamycin derivatives on vaccinia virus morphogenesis.membrane-limited structures, resembling virus envelope precursors previously shown to form during the interruption of poxvirus assembly by rifampin, were now observed by electron microscopy in vaccinia-infected hela cells treated with a series of rifamycin derivatives. the active compounds n-demethyl rifampin, af/dmi, and 3-formyl rifamycin sv lacked, respectively, a methyl group, the piperazine ring, and the hydrazone portion of rifampin. a vaccinia mutant selected only for resistance to rifamp ...19714107245
