Recombinant Japanese encephalitis (JE) vaccine candidates based on a highly attenuated vaccinia virus (NYVAC-JEV) and a canarypox virus (ALVAC-JEV) were evaluated for their ability to induce specific antibodies and cytotoxic T lymphocytes (CTLs) in mice. Six- to eight-week-old male Balb/c mice that received one or two intraperitoneal inoculations with these JE vaccine candidates at a dose of 1 × 10...
An ALVAC (canarypox)-based recombinant virus ALVAC-RHDV (vCP309) expressing a native rabbit hemorrhagic disease virus (RHDV) capsid protein was derived and assessed for its protective efficacy in rabbits. Protection against a lethal RHDV challenge was demonstrated in rabbits inoculated twice with either high (10 7 p.f.u.) or low (10 5 p.f.u.) doses of vCP309. However, animals in...
To identify the active-site residues of the 3C proteinase of foot-and-mouth disease virus (FMDV), we introduced mutations into the 3C coding region and examined the activity of mutant enzymes on various substrates. Based on alignment of FMDV 3C with other picornavirus 3C proteinases and with the trypsin family of serine proteinases, mutations were introduced at residues presumed to be part of the...
A series of double-subgenomic Sindbis virus (dsSIN) recombinants that express cassettes encoding the immunogenic proteins of Japanese encephalitis virus (JEV) [prM-E, prM-E-NS1, NS1-NS2A, 80%E (encodes the amino-terminal 80% part of E), and NS1] were constructed and analyzed for their ability to confer protective immunity in mice against lethal challenge with neurovirulent JEV. The cassettes were...
Double-subgenomic Sindbis virus (dsSIN) recombinants that express cassettes encoding prM-E or a C-terminally truncated form of E of Japanese encephalitis virus (JEV) were constructed. The products were efficiently expressed in both mammalian and mosquito cell lines infected with the dsSIN recombinants. However, suppression of prM-E secretion from mammalian cells infected with dsSIN-prM-E recombinants...
We have previously reported that foot-and-mouth disease virus (FMDV) can enter an Fc receptor (FcR)-expressing cell line by antibody-dependent enhancement. Since FMDV can establish a persistent infection in animals in the presence of high levels of neutralizing antibodies (carrier state), we examined macrophages for their ability to be infected by the virus in the presence of antibody. The murine...
