Enterovirus 71 (EV71) has recently emerged as an important neurotropic virus in Asia because effective medications and prophylactic vaccine against EV71 infection are not available. Based on the success of inactivated poliovirus vaccine, the Vero cell-based chemically inactivated EV71 vaccine candidate could be developed. Identification of EV71 vaccine strain which can grow to high titer in Vero cell...
The efficacy of a novel vaccine composed of three short recombinant subunit Pasteurella multocida toxin (PMT) proteins in combination with a bi-valent P. multocida whole-cell bacterin (rsPMT–PM) was evaluated in field studies for prevention and control of progressive atrophic rhinitis (PAR) of swine at 15 conventional farrow-to-finish farms. Experimental piglets that were immunized twice with the...
We have developed a novel platform technology that can express high levels of recombinant lipoproteins with intrinsic adjuvant properties. In this study, Ag473 (a lipoprotein from Neisseria meningitidis) can be produced in high yields using Escherichia coli strain C43 (DE3). After testing a non-lipoimmunogen (E3, from dengue virus) fused with different lipid signal peptides from other lipoproteins...
Developing an effective vaccine against enterovirus 71 (EV71) infection provides the best means to control the disease. We have previously reported that large-scale preparation of a low immunogenic EV71 strain can be achieved using serum free microcarrier Vero cell culture in a 2-l bioreactor [Wu SC, Liu CC, Lian WC. Optimization of microcarrier cell culture process for the inactivated enterovirus...
The recombinant nucleocapsid (rN) protein of the coronavirus (CoV) responsible for severe acute respiratory syndrome (SARS) was cloned and expressed in Escherichia coli, extracted from cell lysates containing 6M urea, then purified by Ni 2+ -affinity chromatography. In animal immunogenicity studies, we found that most anti-rN protein antibodies were IgG2a in BALB/c mice vaccinated with rN...
Three short fragments of recombinant subunit Pasteurella multocida toxin (rsPMT) were constructed for evaluation as candidate vaccines against progressive atrophic rhinitis (PAR) of swine. PMT-specific antibody secreting cells and evidence of cellular immunity were detected in rsPMT-immunized pigs following authentic PMT challenge or homologous antigen booster. Piglets immunized with rsPMT fragments...
Enterovirus 71 (EV71) is an enterovirus that could lead to severe neurological disorders and fatalities. The inactivated vaccine is an appropriate EV71 vaccine format for meeting current needs. Large-scale preparation of the inactivated EV71vaccine depends on a scalable cell culture system for industrial mass production. In this paper, Vero cells were found to produce higher titers of EV71 than did...
