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 ...
BACKGROUND Inactivated influenza vaccines are manufactured using either split-virion or subunit methods. These 2 methods produce similar hemagglutinin antibody responses, but different cellular immune responses. METHODS We compared the effectiveness of split-virion influenza vaccines to that of subunit influenza vaccines using prospectively collected data from adults aged ≥50 years who sought...
The identification of a large number of antigens with potential for development of new tuberculosis vaccine has been accomplished in recent years. This study was designed for cloning and expression of ESAT-6 as a potent antigen of Mycobacterium tuberculosis. Selected gene (Rv3875) was amplified by PCR and product was ligated into expressing plasmid vector pQE30 and recombinant pQE30-ES plasmi...
background: enterotoxigenic escherichia coli (etec) strains are the major causes of diarrheal disease in humans and animals. colonization factors and enterotoxins are the major virulence factors in etec pathogenesis. for the broad-spectrum protection against etec, one could focus on colonization factors and non-toxic heat labile as a vaccine candidate. methods: a fusion protein is composed of a...
Leptospirosis, a worldwide zoonosis, lacks an effective, safe, and cross-protective vaccine. LipL32, the most abundant, immunogenic, and conserved surface lipoprotein present in all pathogenic species of Leptospira, is a promising antigen candidate for a recombinant vaccine. However, several studies have reported a lack of protection when this protein is used as a subunit vaccine. In an attempt...
Bovine viral diarrhea virus (BVDV) is an important cause of economic losses worldwide. E2 is an immunodominant protein and a promising candidate to develop subunit vaccines. To improve its immunogenicity, a truncated E2 (tE2) was fused to a single chain antibody named APCH, which targets to antigen-presenting cells. APCH-tE2 and tE2 proteins were expressed in the baculovirus system and their im...
background and objectives: brucella melitensis infection is still a major health problem for human and cattle in developing countries and the middle east. materials and methods: in this study, in order to screen immunogenic candidate antigens for the development of a brucella subunit vaccine, a cytoplasmic protein (dnak) and an outer membrane protein (omp31) of b. melitensis were cloned, expres...
