This work was designed to provide high protective, long-lasting immunity against FMD by enhancing the immunogenicity of trivalent vaccine using carbomer as adjuvant G. pigs an alternative cheapest animal model for quality control testing prepared vaccines formulae. Guinea were chosen experimental models develop concepts and techniques study PD50 because similarities clinical symptoms in these a...

We studied the safety of a trivalent inactivated surface antigen (split virion, inactivated) influenza vaccine, Begrivac® (Novartis Company), widely used in health care workers in Kurdistan. A longitudinal follow-up study was performed in Sanandaj city, west of Iran, recruiting 936 people. A questionnaire was completed for each participant, and all symptoms or abnormal physical findings were re...

Severe climate change and global warming may impact significantly on vector-borne disease including Japanese encephalitis (JE) infection in human and animals. Thus, veterinary authority requires large quantity of diagnostic tools to survey vector-borne diseases. New producing method having a relation with JE antigen is needed to substitute conventional sucrose-acetone extraction method using su...

In these last years, we are witnessing the emergence of a new class biopharmaceuticals based on messenger RNA (mRNA). One most promising applications mRNA is its use as vaccines. Many reports, including ours, have demonstrated preclinical efficacy vaccines several advantages over traditional or even DNA Unlike attenuated inactivated vaccines, encodes for specific antigen that will be expressed ...

Helicobacter pylori (H. pylori) is a gram-negative, microaerophilic bacterium that cause the stomach infection in more than 50% of human population worldwide. The aim of this study was to examine the possibility of anti-H. pylori immunoglobulins Y (IgYs) production in quails and evaluate the effect of the different methods of immunization on titers of IgY in egg yolks. Whole cell bacterial anti...

Japanese encephalitis virus (JEV) is an enveloped icosahedral capsid with a prime neutralizing epitope present in E protein domain III (EDIII). dimers are rearranged into five-fold symmetry of icosahedrons. Cholera toxin B (CTB) and heat-labile enterotoxin (LTB) AB5-type was used as the structural scaffold for emulating pentameric axis EDIII. We produced homo-pentameric EDIII through genetic fu...

The severe consequences and high mortality of COVID-19 prompted the development a wide range preventive vaccines. first vaccines to be tested were developed in China formulated as inactivated SARS-CoV-2 adsorbed on aluminium hydroxide. One quality indicators for is degree adsorption, which can used control content not only non-adsorbed antigen, but also specific antigen one dose vaccine. aim st...

A microtitration agglutination test for the detection of Treponema hyodysenteriae antibody in swine and rabbit sera is described. The following methods provided the best test results: antigen produced from the spirochete after a culturing period of 36 to 44 h at 38 degrees C, washed antigen inactivated with 0.01% Merthiolate at 4 degrees C for 24 to 36 h, sera heated at 56 degrees C for 30 min,...
