Among the known human rotavirus serotypes, types G1–G4 are ubiquitous and account for >80% of global human rotavirus strains. Since 1994 an increase in reports of G9 serotype isolates has been observed in both developed and developing countries. In the winter season of 1999–2000 we detected the appearance of G9 rotavirus in Palermo, Italy, accounting for 19% of all rotaviruses circulating in our geographical area. Some of these Italian G9 isolates have been submitted to partial sequencing of their VP7 gene. All of them showed complete nucleotide identity suggesting a clonal origin. The Italian VP7 sequences were found to be very closely related to that of other G9 strains recently isolated in Europe, America, Africa and Asia. Our results confirm that G9 strains circulating worldwide since 1994 are closely related genetically in their VP7 genes.

Porcine circovirus type 2 (PCV2) is recognized as a primary cause in post-weaning multisystemic wasting syndrome (PMWS). In this study, both PCV1 and PCV2 types were studied in pigs originating from PMWS-affected (+) and non-affected (−) herds from Brittany. PCV2 was identified by PCR in 100 % of animals from PMWS(+) herds and in 76 % from PMWS(−) herds, while PCV1 was not detected. The complete sequences of 38 PCV2 isolates were determined and 23 new variants were identified, displaying between 94·6 and 99·9 % nucleotide identity with one another. Although highly related to all the PCV2 sequences available in databases, the isolates from France gathered in a distinct subcluster. Compared with the 13 PCV2 from PMWS(+) farms, the 10 PMWS(−) sequences exhibited a slightly higher variability. No viral molecular marker specific to a pathogenic state could be identified, even by including other PCV2 variants isolated from PMWS-suffering animals from other countries. We concluded that the PMWS outbreaks in Brittany are most likely not due to the emergence of a new genotype of circovirus.
