Chitosan-DNA nanoparticles enhanced the immunogenicity of multivalent DNA vaccination on mice against Trueperella pyogenes infection

BACKGROUND Trueperella pyogenes is a commensal and opportunistic pathogen that normally causes mastitis, liver abscesses and pneumonia of economically important livestock. To develop efficacious and potent vaccine against T. pyogenes, chimeric gene DNA vaccines were constructed and encapsulated in chitosan nanoparticles (pPCFN-CpG-CS-NPs). RESULTS The pPCFN-CpG-CS-NPs consists of the plo, cbp...

Oral Vaccination Based on DNA-Chitosan Nanoparticles against Schistosoma mansoni Infection

The development of a vaccine would be essential for the control of schistosomiasis, which is recognized as the most important human helminth infection in terms of morbidity and mortality. A new approach of oral vaccination with DNA-chitosan nanoparticles appears interesting because of their great stability and the ease of target accessibility, besides chitosan immunostimulatory properties. Here...

Multivalent HA DNA Vaccination Protects against Highly Pathogenic H5N1 Avian Influenza Infection in Chickens and Mice

BACKGROUND Sustained outbreaks of highly pathogenic avian influenza (HPAI) H5N1 in avian species increase the risk of reassortment and adaptation to humans. The ability to contain its spread in chickens would reduce this threat and help maintain the capacity for egg-based vaccine production. While vaccines offer the potential to control avian disease, a major concern of current vaccines is thei...

Combined DNA vaccination against three animal viruses elicits decreased immunogenicity of a single plasmid in mice.

In order to investigate whether combined DNA vaccines are an ideal way to combine antigens in a single vaccine formulation, we immunized mice with three plasmids (pVSG, pVgD and pVE2), respectively, encoding the antigen of foot-and-mouth disease virus (FMDV), pseudorabies virus (PRV) and classic swine fever virus (CSFV), either alone or in a combined vaccine regimen. We also investigated the im...

Immunization against Egyptian Schistosoma mansoni infection by multivalent DNA vaccine.

The development of multivalent vaccines consisting of several antigens is a novel approach to creating broad-range protection against different parasite strains and parasite life cycle stages. We have previously confirmed that the schistosome Sm21.7 and SmFimbrin (SmFim) proteins could induce protection in mice. Therefore, this study aimed to construct the multivalent DNA vaccine Sm21.7-SmFim/p...
