Peste des petits ruminants is a highly contagious viral disease of small ruminants making its diagnosis difficult from the similar symptoms of Rinderpest. Computer based prediction algorithms was applied to identify antigenic determinants on the nucleocapsid (N) protein of PPRV. Specificity and antigenicity of each peptide was evaluated by solid phase(More)
UNLABELLED Recently, transgenic plants expressing immunogenic proteins of foot-and-mouth disease virus (FMDV) have been used as oral or parenteral vaccines against foot-and-mouth disease (FMD). They exhibit advantages like cost effectiveness, absence of processing, thermostability, and easy oral application. FMDV VP1 protein of single serotype has been(More)
BACKGROUND Foot and mouth disease (FMD) can be controlled by regular vaccination and restriction of the movement of infected animals in the endemic countries. Although presently used, tissue culture inactivated vaccine gives protection, it has several limitations, including a short duration of immunity. DNA vaccine delivered through microparticles could(More)
Expressions of several genes in bacteria were carried out by independent promoter. However, in case of eukaryotes ribosome skipping and introduction of IRES are employed as alternative to multiple translation initiation. Foot and mouth disease virus (FMDV) 2A peptide has been widely used for co-expression of multiple genes in eukaryotic, plant and mammalian(More)
Foot and mouth disease (FMD) outbreaks usually have devastating effects on the economy of countries were disease is endemic due to direct and indirect cost; most of them related to international trade embargoes of animals and animal products. Although currently used inactivated vaccine provides protection, it has several drawbacks like short duration of(More)
DNA vaccines are considered as alternatives to live attenuated ones for those diseases like foot-and-mouth disease (FMD) where the production and application of live vaccines have been found unsuccessful. However, stability of DNA and the quantity of antigen expressed are the major limitation with naked DNA vaccines. To address these issues self replicating(More)
AIM Interleukin 7 (IL-7) is a ϒc family cytokine involved in the homeostatic proliferation and maintenance of immune cells. In the present study, we report the expression of bovine IL-7 (bIL-7) in Escherichia coli and evaluated for its biological activity. MATERIALS AND METHODS The sequence coding for bIL-7 (mature protein) was amplified from primary(More)
The limited efficacy of DNA vaccines against foot-and-mouth disease (FMD) in cattle and other natural hosts has prompted a search for a more effective vaccination regimen. In this study we tested a DNA prime-protein boost vaccination strategy against FMD in bovine calves. We used purified recombinant FMDV specific multi-epitope protein (rMEG990) and an(More)
Information on the structure and character of immunoglobulin of fishes is essential in health management. A study was carried out to characterize the serum immunoglobulin (IgM) of the Indian major carp, rohu Labeo rohita (Ham.). Rohu (500g) were immunised with bovine serum albumin (BSA) and the anti-BSA antibody was purified employing BSA-CL agarose(More)
Dendritic cells (DC) which are located at the interface of innate and adaptive immunity are targets of infection by many RNA and DNA viruses. Advances in the ex vivo generation of monocyte derived non proliferating dendritic cells have been used for clinical application like immunotherapy. IL-4 cytokine plays essential role in the maturation and generation(More)
