The standard serological methods present limitations for the measurement of immunity against H5N1 influenza strains. The hemagglutination inhibition (HI) assay lacks sensitivity and requires standardization, while the viral micro-neutralization (MN) assay needs handling of live virus. We produced pseudoparticles expressing hemagglutinin from clades 1 or 2 H5N1 in order to measure neutralizing antibodies...
Effective diagnostic and therapeutic strategies are needed to control and combat the highly pathogenic avian influenza virus (AIV) subtype H5N1. To this end, we developed human monoclonal antibodies (mAbs) in single chain fragment variable (scFv) format towards the H5N1 avian influenza virus to gain new insights for the development of immunotherapy against human cases of H5N1. Using a biopanning based...
We conducted a cross-sectional seroprevalence study of varicella-zoster virus (VZV) antibodies in childbearing age women aged 17–42 years. Sera were collected in Central Italy in years 2001–2002 and were tested by a commercial VZV IgG enzyme immunoassay. Overall VZV seroprevalence was 80.9% and it showed a significant increase by age, confirming a considerable circulation of VZV also in the older...
