A new recombinant West Nile virus (WNV) vaccine has been licensed for use in horses. Prior to the availability of the recombinant vaccine in 2004, the only equine WNV vaccine available on the market had been an inactivated vaccine. Since the recombinant vaccine only expresses selected viral genes, the question could be posed as to whether a single dose of the recombinant vaccine would be effect...
While recombinant Listeria monocytogenes strains can be explored as vaccine candidates, it is important to develop attenuated but highly immunogenic L. monocytogenes vaccine vectors. Here, prfA* mutations selected on the basis of upregulated expression of L. monocytogenes PrfA-dependent genes and proteins were assessed to determine their abilities to augment expression of foreign immunogens in ...
newcastle is a significant avian disease continuing to cause considerable loss. developments in genetic engineering have led to plant-based platforms for human and animal vaccine production. recombinant vaccine production in hairy root systems have several advantages over stable expression in whole plants, including high growth rates, ready genetic manipulations, high levels of recombinant prot...
objective: to compare immunogenicity of a recombinant hepatitis b (hb) vaccine in two groups of neonates born in two cities of iran with different geographic and ethnic backgrounds. materials and methods: ten micrograms of a recombinant hb vaccine was administered under field condition to iranian healthy neonates at 0, 1.5 and 9 months intervals. the subjects consisted of two groups of 290 an...
Brucellosis is caused by the bacterium Brucella and affects various domestic and wild species. GroEL (Heat Shock Protein 60kDa) as one of the major antigens that stimulate the immune system, increases Brucella survival. The aim of the current study was to clone and express GroEL in Escherichia coli in order to design subunit vaccine. Amplifying was performed using specific primers. The full-len...
Background & Aims: Salmonella enterica is a zoonotic pathogen causing typhoid fever in humans and animals. It is an important cause of food borne infections in humans throughout the world. A recent study estimated approximately 22 million cases of typhoid each year with at least 200,000 deaths. FliC encoding flagellin plays a role in pathogenesis and is an important antigen in vaccination....
Objective(s): The results of studies on vaccine development for foot-and-mouth disease (FMD) virus show that the use of inactivated vaccines for FMD virus is not completely effective. Novel vaccinations based on immuno-dominant epitopes have been shown to induce immune responses. Furthermore, for safety of immunization, access to efficient adjuvants against FMD virus seems to be critical.Materi...
Background and Aims: Virus-like particles (VLPs) have been suggested to be a promising recombinant vaccine approach. Several studies have reported that the influenza VLPs produced in insect cells is an effective vaccine candidate. Due to crucial role of matrix M1 protein in assembly and budding of Influenza particles, in all VLPs structures, M1 protein have been considered as a main component. ...
Introduction: The cattle tick Rhipicephalus spp. causes significant economic losses due to diseases in animals and human. Bm86 is a midgut protein and vaccine candidate, which its sequences among the isolates of Ripsephalus spp are geographically separated, variable, and are the main reason for reducing effectiveness, and subsequently, the failure of the recombinant vaccines. Method: In this bi...
