Cutaneous hypersensitivity test to evaluate phage display anti-tick borne vaccine antigen candidates

Novel phage display-based subtractive screening to identify vaccine candidates of Brugia malayi.

This study describes a novel phage display method based on an iterative subtraction strategy to identify candidate vaccine antigens of Brugia malayi. A cDNA library of the infective larval stage of B. malayi expressed on the surface of T7 phage was sequentially screened with sera samples from human subjects showing different manifestations of the disease. Antigens that selectively and specifica...

Single-dose vaccine against tick-borne encephalitis.

Tick-borne encephalitis (TBE) virus is the most important human pathogen transmitted by ticks in Eurasia. Inactivated vaccines are available but require multiple doses and frequent boosters to induce and maintain immunity. Thus far, the goal of developing a safe, live attenuated vaccine effective after a single dose has remained elusive. Here we used a replication-defective (single-cycle) flavi...

Direct Immunogenic Antigen to Dendritic Peptides Identified through Phage Display

Puzzling Peptides from a Phage Display Library

The commercial availability of random peptide libraries displayed on the M13 phage is increasing their use forstudies on epitope identification, enzyme inhibitors, receptor ligands, etc. In this study two experimentswhere planned for selection of peptides. First with sheep antibodies, the positive selector was IgG, preparedon Protein G column from a pool of 11 sheeps immunized...

Fatal Outcome of European Tick-borne Encephalitis after Vaccine Failure

Tick-borne encephalitis is a viral disease affecting the central nervous system. It is endemic in Switzerland with 200-250 notified cases annually. Active immunization is effective for persons in all age groups. Vaccine failure is rare, in particular after a completed vaccination course. Here, we describe the case of 67-year-old man with a fatal outcome despite vaccination. The diagnosis was co...
