The efficacy of an inactivated foot-and-mouth disease (FMD) vaccine is mainly dependent on the integrity of the foot-and-mouth disease virus (FMDV) particles. At present, the standard method to quantify the active component, the 146S antigen, of FMD vaccines is sucrose density gradient (SDG) analysis. However, this method is highly operator dependent and difficult to automate. In contrast, the ...

there are little information about growth properties of low pathogenic (lp) avian influenza virus (aiv) in embryonated chicken eggs (eces) at different incubation temperatures. knowledge of this information increases the quantity and quality of antigen in vaccine production process. for this purpose, 10-5 dilution of aiv (a/chicken/iran/99/h9n2) was inoculated (intra-allantoic) into 400, 11-day...

During the formation of incomplete fowl plague virus, normal amounts of viral compounds are synthesized. The S-antigen, however, cannot be demonstrated within the cytoplasm in appreciable amounts by fluorescent antibody. The oligonucleotide pattern and the specific radioactivity of the ribonucleic acid (RNA) of incomplete forms are almost identical with those of standard virus. In contrast to c...

Equitable global access to vaccines requires overcoming challenges associated with complex immunization schedules and their economic burdens that hinder delivery in under-resourced environments. The rabies vaccine, for example, multiple immunizations effective protection each dose is cost prohibitive, therefore inaccessibility disproportionately impacts low- middle-income countries. In this wor...

Many studies are currently investigating the development of safe and effective vaccines to prevent various infectious diseases. Multiple antigen-presenting peptide vaccine systems have been developed to avoid the adverse effects associated with conventional vaccines (i.e., live-attenuated, killed or inactivated pathogens), carrier proteins and cytotoxic adjuvants. Recently, two main approaches ...

foot-and-mouth disease is an important viral disease of cloven-hoofed animals. inactivated whole particle virus vaccines are still widely used in prophylactic vaccination campaigns. the choice of adjuvant is a very important factor in enhancing immune responses and the efficacy of inactivated vaccines. montanide isa 61 vg is a new ready-to-use mineral oil-based adjuvant developed by seppic inc....
