Mapping of antigenic sites of foot-and-mouth disease virus serotype Asia 1 and relationships with sites described in other serotypes.

Knowledge of the antigenic structure of foot-and-mouth disease virus (FMDV) has relevance in the development of diagnostic assays, in the evaluation of the antigenic variability and in the selection of appropriate vaccine strains. Antigenic sites have been investigated only in FMDVs of serotypes O, A and C, while it would be valuable to extend studies also to other serotypes. This paper reports the identification of antigenic sites involved in virus neutralization in the FMDV serotype Asia 1 by using a new panel of mAbs and their relation with sites described in other serotypes is discussed.

Genetic and antigenic characterization of infectious bursal disease viruses isolated in Italy during the period 2002-2005.

During the period 2002-2005, 109 infectious bursal disease virus (IBDV) field strains were isolated from bird flocks located in various parts of Italy. Out of these strains, 91 were isolated from broilers, 12 from pullets, and six from backyard flocks. Forty-two IBDV strains were further investigated and characterized on the basis of the geographical origin, source, and clinical signs.

Assessment of human enteric viruses in shellfish from the northern Adriatic sea.

Incidence and circulation of different strains of hepatitis A and Norovirus in shellfish were studied on 235 samples (Tapes philippinarum, Mytilus galloprovincialis, Ostrea spp. and Chlamys spp.) obtained from different sites, representing the shellfish production areas of the northern Adriatic sea.
