Detection and molecular characterization of human rotaviruses isolated in Italy and Albania.

Rotaviruses are one of the most important causes of gastroenteritis in children under 5 years old. Analysis of G and P rotavirus genotypes in circulation is crucial in evaluating the appropriacy of mass vaccination of children worldwide. Overall, 592 stool samples were collected in Tirana (Albania), the Salento peninsula (South Italy), and three different hospitals in Rome (Central Italy).

Identification and sequence analysis of hepatitis A virus detected in market and environmental bivalve molluscs.

In Italy in 1998, hepatitis A virus (HAV) was responsible for an infectious disease transmitted by contaminated bivalve molluscs. To determine the presence of HAV in the bivalves collected during a 1-year follow-up study, hepatitis A RNA was extracted and amplified by a nested reverse transcriptase-PCR method overlapping the VP1/2A region. The HAV genome was detected in 24 (14.
