A DNA vaccine for foot and mouth disease (FMD) based on mannosylated chitosan nanoparticles was evaluated in guinea pigs. The DNA construct was comprised of FMD virus full length-VP1 gene and outer membrane protein A (Omp A) gene of Salmonella typhimurium as a Toll-like receptor (TLR)-ligand in pVAC vector. Groups of guinea pigs immunized either(More)
Bacterial ghosts (BGs) are empty cell envelopes derived from Gram-negative bacteria. They not only represent a potential platform for development of novel vaccines but also provide a tool for efficient adjuvant and antigen delivery system. In the present study, we investigated the interaction between BGs of Escherichia coli (E. coli) and bovine(More)
Despite their potential role in the spread of foot-and-mouth disease (FMD), the immune response and viral persistence in FMD virus (FMDV)-infected Indian buffaloes (Bubalus bubalis) have been unexplored. We found similar kinetics of neutralizing antibody responses in the sera and secretory fluids of buffaloes following experimental FMDV Asia 1 infection,(More)
Despite significant advancements in modern vaccinology, inactivated whole virus vaccines for foot-and-mouth disease (FMD) remain the mainstay for prophylactic and emergency uses. Many efforts are currently devoted to improve the immune responses and protective efficacy of these vaccines. Adjuvants, which are often used to potentiate immune responses,(More)
Foot-and-mouth disease virus (FMDV) is one of the most contagious animal virus known that affects livestock health and production. This study aimed to investigate the effect of flagellin, a toll-like receptor 5 agonist, on the immune responses to inactivated FMDV antigen in guinea pig model. Our results showed that the co-administration of flagellin with(More)
The interest in analysing antigen-specific cytokine responses has substantially increased in recent years, in part due to their use in assessing vaccine efficacy. In the present study, the kinetics of IL-2, IL-4 and IFN-γ expression was determined in bovine PBMCs by real-time PCR and in whole blood by cytokine-release assay after in vitro stimulation with(More)
The mucosal immune response to foot-and-mouth disease virus (FMDV) type Asia 1 was examined in experimentally infected cattle by assaying antibodies by the virus-neutralizing test (VNT) and IgA ELISA in two secretory fluids, oesophageal pharyngeal fluid (OPF) and oro-nasal fluid (ONF). Out of 17 animals infected by the intradermo-lingual route, 12 became(More)
We are reporting you an effective DNA vaccine for FMD virus, and it was prepared using mannosylated chitosan (MC) nanoparticles to form the FMDV-pVAC-VP1-OmpA complex particles. These particles were characterized for their physical properties like morphology, size and charge prior evaluating the actual vaccine delivery effect of MC-nanoparticles. The(More)
Flagellin, a Toll-like receptor 5 (TLR5)-ligand, is known for its activities like adjuvant, induction of pro-inflammatory cytokines and innate immunity. In this context, fliC gene of Salmonella Typhimurium was cloned into pET32a expression plasmid using in-house designed gene specific primers. The frame and orientation of the inserted fliC gene was(More)
Foot-and-mouth disease (FMD), the most contagious animal disease, is associated with persistent viral infection in ruminants, despite the induction of systemic immune response. The present study was performed to decipher the relation between the persistent FMD virus (FMDV) infection and cellular immune response in Indian cattle (Bosindicus) following(More)
