White spot syndrome virus (WSSV) is a highly pathogenic and prevalent virus affecting shrimp culture worldwide including Iran. In the present study, a pair of primers was designed according to the sequence of VP 28 gene of WSSV in the GenBank. VP28 gene from an Iranian WSSV isolate (IrVP28) was cloned, sequenced and expressed in Escherichia coli BL21(DE3) strain in order to produce VP28 protein...

The heterologous DNA prime‑protein boost vaccination approach has been widely applied as an immune treatment for carcinoma. However, inefficient delivery of DNA remains a major issue. In the present study, polyethyleneimine (PEI) was used as a DNA vector carrier to improve the transfection efficiency of the DNA vaccine and stimulate the humoral and cellular immunity against the renal carcinoma‑...

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 U...

PURPOSE Helicobacter pylori is a widely distributed gram-negative bacterium that infects the human stomach and duodenum. HpaA is a H. pylori-specific lipoprotein that has been shown to be an effective protective antigen against H. pylori infection. HpaA of H. pylori as a vaccine antigen is fully competent for stimulation of immune responses. The aim of this project is cloning, expression, and p...

Background Cystic echinococcosis (CE), as a zoonotic disease cause to health threat and economic losses. Despite implemented control programs, few countries have been able to decrease or eliminate this infection. Vaccination of the intermediate host offers an additional strategy to control the parasite transmission and EG95 antigen is considered more than the others in the vaccine issue. Accord...

In the study of the regulation of incubation, broodiness and laying performance in pigeons (Columba liva), a cDNA library, which was enriched with full-length brooding-related genes, was constructed by SMART LD-PCR techniques using the pituitary glands of incubating White King pigeons. The titers of optimal primary libraries were 1.54x10(6) pfu/mL and 1.80x10(6) pfu/mL and the titers of amplifi...

Plague is one of the most dangerous infections in humans caused by Yersinia pestis, a Gram-negative bacterium. Despite of an overwhelming research success, no ideal vaccine against plague is available yet. It is well established that F1/LcrV based vaccine requires a strong cellular immune response for complete protection against plague. In our earlier study, we demonstrated that HSP70(II) of My...

BACKGROUND Mycobacterium tuberculosis is a vicious microbe co-existing with the infected host. This pathogen exploited opportunities to spread during periods of urbanization and social upheaval, and got retreated with improved hygiene. OBJECTIVES This investigation was designed to clone and characterize M. tuberculosis mutT gene, a homologue of a DNA repair protein in Escherichia coli. The ai...
