Background: Cutaneous leishmaniasis (CL) is a serious public health problem in many tropical countries. The infection is caused by a protozoan parasite of Leishmania genus transmitted by Phlebotominae sandflies. In the present study, we constructed a eukaryotic expression vector to produce a fusion protein containing LmSTI1 from Leishmania major (L. major) and PpSP42 from Phlebotomus papatasi (...

Objective(s): After decades of containment, pertussis disease, caused by Bordetella pertussis seems to be re-emerging and still remains a major cause of reported vaccine-preventable deaths worldwide. The current licensed whole-cell vaccines display reactogenicity while acellular vaccines are expensive and do not induce Th1-type immune responses that are required for optimum protection against t...

globally, brucella melitensis and b. abortus are the most common cause of human brucellosis. the outer membrane protein 31 (omp31) and l7/l12 are immunodominant and protective antigens conserved in human brucella pathogens which are considered as potential vaccine candidates. we aimed to design the fusion protein from brucella l7/l12 and truncated omp31proteins, in silico , clone the fusion in ...

Background: Dengue is a global arboviral threat to humans; causing 390 million infections per year. The availability of safe and effective tetravalent dengue vaccine is a global requirement to prevent epidemics, morbidity, and mortality associated with it. Methods: Five experimental groups (6 mice per group) each of 5-week-old BALB/c mice were immunized with vaccine and placebo (empty plasmid) ...

background and objectives: urinary tract infection (uti) is one of the most common infections in the world. the majority of utis are caused by uropathogenic escherichia coli (upec) strains. fimh and flic are the most important virulence factors of upec. to date, any ideal vaccine against uti has not been approved for human use and we need to test new targets to develop an ideal vaccine against ...

Objective(s): The porins A and B and also outer membrane vesicles (OMVs) of Neisseria meningitidis are used for vaccine purposes. In the present study, we aimed to design a new vaccine candidate based on a fusion of PorA of serogroups A and B of N. meningitidis admixed with OMV and evaluate it in an animal model.Materials and Methods: Af...

Objective(s):Human Cytomegalovirus (HCMV) remains a major morbidity and mortality cause in immuno suppressed patients. Therefore, significant effort has been made towards the development of a vaccine. In this study, the expression of the pp65 and gB fusion peptides and Fc domain of mouse IgG2a as a novel delivery system for selective uptake of antigens by antigen-presenting cells (APCs) in Pich...

Background: The purpose of this study was to clone, express, and purify a novel multidomain fusion protein of Micobacterium tuberculosis (Mtb) in a prokaryotic system. Methods: An hspX/esxS gene construct was synthesized and ligated into a pGH plasmid, E. coli TOP10 cells were transformed, and the vector was purified. The vector containing the construct and pET-21b (+) plasmid were digested ...

Designing and producing a proper fusion construction is the most important problem of producing large quantities of a properly folded functional protein. This construction should have all necessary components of a real gene. A good designed fusion gene construction could be cloned into a good and suitable host. Clostridium perfringens is an important pathogen of humans and livestock and produce...
