Recombinant hemagglutinin (HA) from a novel H1N1 influenza strain was produced using an alphavirus replicon expression system. The recombinant HA vaccine was produced more rapidly than traditional vaccines, and was evaluated as a swine vaccine candidate at different doses in a challenge model utilizing the homologous influenza A/California/04/2009 (H1N1) strain. Vaccinated animals showed signif...
background: various prokaryotic and eukaryotic expression systems have been developed for the production of recombinant proteins. in the present study, we used a new protein expression system based on the iranian lizard leishmania, a trypanosomatid protozoan as a host, for the expression of lpg3 gene from leishmania infantum (l.infantum). methods: the lpg3 gene was cloned in the expression cass...
The global outbreak of novel A/H1N1 spread in human population worldwide has revealed an emergency need for producing a vaccine against this virus. Current influenza vaccines encounter problems with safety issues and weak response in high-risk population. It has been established that haemagglutinin is the most important viral antigen ...
Conventional parenteral injection of vaccines is limited in its ability to induce locally-produced immune responses in the respiratory tract, and has logistical disadvantages in widespread vaccine administration. Recent studies suggest that intranasal delivery or vaccination in the respiratory tract with recombinant viral vectors can enhance immunogenicity and protection against respiratory dis...
Recently, canine distemper virus (CDV) has been linked to population declines in the endangered African wild dog (Lycaon pictus). As CDV appears able persist wildlife, threats free-ranging dogs cannot be eliminated by vaccinating domestic dogs. Conservation managers may therefore consider vaccination of highly threatened populations. For use field conservation, ideal vaccine would safe, immunog...
Background: Crimean-Congo hemorrhagic fever (CCHF) is an acute viral zoonotic disease, with a mortality rate of 30-50%. There is no approved vaccine or any specific antiviral treatment for CCHF; therefore, the rapid diagnosis seems to be crucial for both efficient supportive therapy and control of infection spread. In this study, the potency of recombinant nucleoprotein of virus expressed in pr...
conclusions results indicates that antigenic region of recombinant caga protein were recognized as an antigen , so it might be a candidate for the development of h. pylori vaccine, elisa kit designs and serological diagnosis of h. pylori infections. background helicobacter pylori is a human pathogen that causes chronic gastritis, which playsrole in gastric and duodenal ulcers, is also involved ...
Specific humoral immune responses in a clinical trial on cattle for vaccines against contagious bovine pleuropneumonia (CBPP) were investigated. The trial included a subunit vaccine consisting of five recombinant putative variable surface proteins of the infectious agent Mycoplasma mycoides subsp. mycoides small colony type (M. mycoides SC) compared to the currently approved attenuated vaccine ...
