background and objectives: urinary tract infection (uti) is one of the most common infections in human, and uropathogenic escherichia coli (upec) strains are the most common cause of uti. these strains colonize in bladder and cause cystitis, which could cause pyelonephritis by movement to the kidneys. since fimh protein has a very important role in colonization of upec strains and causing infec...

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...

One way to confront chemical warfare in order to reduce their harmful effects, is to use the body's defense mechanisms. In order to do so firstly mustard gas (HD) was injected in an animal model in the form of an immunogen and the induced humoral immune response was investigated by two different immunological methods such as the Ouchterlony test and a new liquid phase fluoroimmunoassay. 7l...

we developed an immunogen to stimulate multivalent immunity against hepatitis b surface antigen (hbsag) and hepatitis b core antigens (hbcag). immune responses specific for both hbsag and hbcag play an important role in controlling the infection. hbsag-specific antibodies mediate elimination of virions at an early stage of infection and prevent the spread of virus. the immunogen was constructed...
