Phage display techniques have been widely employed to map the epitope structures which served as the basis for developing molecular vaccines. In the present study, we applied this technique to map the epitopes of Mycoplasma hyopneumoniae, the etiologic agent causing swine enzootic pneumonia, and evaluated directly the immune responses in mice of the selected phage-displayed epitopes (phagotopes...

Trichinellosis is one of the most important food-borne parasitic zoonoses throughout the world. Because infected pigs are the major source of human infections, and China is becoming the largest international producer of pork, the development of a transmission-blocking vaccine to prevent swine from being infected is urgently needed for trichinellosis control in China. Our previous studies have d...

Pneumonic plague is a highly virulent infectious disease with 100% mortality rate, and its causative organism Yersinia pestis poses a serious threat for deliberate use as a bioterror agent. Currently, there is no FDA approved vaccine against plague. The polymeric bacterial capsular protein F1, a key component of the currently tested bivalent subunit vaccine consisting, in addition, of low calci...

Objective(s): Phage therapy is a potential alternative treatment for infections caused by Acinetobacter baumannii, a significant nosocomial pathogen, which has evolved resistance to almost all conventional antimicrobial drugs in poor hygiene and conflicts areas such as Iraq. Materials and Methods: Bacteriophages were isolated to highly resistant isolates of A. baumannii to form therapeutic phag...

We have designed, developed and produced a lambdaphage based anti-cancer vaccine (nano-particle) targeting human aspartyl (asparaginyl) b-hydroxylase (HAAH). This follows accumulated evidence that HAAH meets requirements of a good target for anti-cancer immunotherapy. The protein is over-expressed on the surface of cancer cells and plays a central role in cancer etiology that effects cancer cel...

Microbial surface and secreted proteins (the secretome) contain a large number of proteins that interact with other microbes, host and/or environment. These proteins are exported by the coordinated activities of the protein secretion machinery present in the cell. A group of bacteriophage, called filamentous phage, have the ability to hijack bacterial protein secretion machinery in order to amp...

For the past 25 years, phage display technology has been an invaluable tool for studies of protein-protein interactions. However, the inherent biological, biochemical, and biophysical properties of filamentous bacteriophage, as well as the ease of its genetic manipulation, also make it an attractive platform outside the traditional phage display canon. This review will focus on the unique prope...

Random heptapeptide library displayed by bacteriophage T7 was used to characterize epitopes of five monoclonal antibodies that were specific to L. australis, L. bangkok, and L. bratislava. Phages selected by biopanning were cloned by plaque isolation, and the binding specificity of individual clones was confirmed by enzyme-linked immunosorbent assay, before being further amplified and checked f...
