Patas monkeys (Eryphrocebus patas) were immunized intradermally with two vaccinia virus recombinants that individually express the hemagglutinin-neuraminidase glycoprotein or the fusion glycoprotein of human parainfluenza virus type 3 (PIV3). These immunizations induced a high titer of PIV3 serum-neutralizing antibodies. At 1 month after immunization, monkeys were challenged intratracheally with PIV3. Subsequent virus replication was reduced in these monkeys by 3.2 log10 and 1.9 log10 (mean peak virus titers) in the upper and lower respiratory tracts, respectively, compared with control animals. The average duration of virus shedding was also reduced from 9.0 to 3.4 days in the upper respiratory tract and from 5.3 to 1.2 days in the lower respiratory tract. These findings demonstrate that a single intradermal dose of live recombinant vaccinia viruses can significantly restrict the replication of a virus which primarily infects the epithelial cells of the respiratory tract.

UI MeSH Term Description Entries
D010224 Parainfluenza Virus 3, Human A species of RESPIROVIRUS frequently isolated from small children with pharyngitis, bronchitis, and pneumonia. Hemadsorption Virus 1,Human parainfluenza virus 3,Para-Influenza Virus Type 3,Parainfluenza Virus Type 3,Para Influenza Virus Type 3
D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
