摘要:The National Rotavirus Reference Centre together with collaborating laboratories Australia-wide hasconducted rotavirus surveillance since June 1999. The serotypes of rotavirus strains that areresponsible for the hospitalisation of children with acute gastroenteritis were determined for theperiod 1 June 2001 to 31 June 2002. We examined 754 rotavirus samples using a combination ofmonoclonal antibody immunoassay, reverse transcription-polymerase chain reaction, and Northernhybridisation. For the first time, serotype G9 strains were the most prevalent type nationally (40.4%)and found in 8 of the 9 centres. Serotype G1 strains were the second most prevalent type (38.9%),identified in 5 of the centres. These findings have important implications for vaccine developmentstrategies which target serotypes G1-G4
