Electropherotypes, subgroups and serotypes of human rotavirus strains causing gastroenteritis in infants and young children in Palermo, Italy, from 1…

1990

During 1985-89, an epidemiological survey was conducted in Palermo, Sicily (Southern Italy) on group A human rotavirus (HRV) strains which cause gastroenteritis in infants and young children. Two hundred and thirty eight HRV strains were characterized for subgroup and serotype using monoclonal-antibody-based ELISA systems, and for electropherotype using polyacrylamide gel electrophoresis. Subgroup II strains were largely predominant, constituting 218/238 of the positive stool samples (91.6%). Among the serotypes, 192/238 strains (80.7%) were serotype 1 and 16 strains (6.7%) were serotype 4; serotype 2 circulated intermittently and serotype 3 was nearly absent (only one subgroup I strain was…
