Novel rotaviruses in animals and XXXX .

Novel (non- @entity7414 have many of the morphological, biochemical and biological properties described originally for @entity7414 but they do not share the same group antigens. By negative-stain electron microscopy, novel rotaviruses have the characteristic rotavirus morphology, although with some novel rotaviruses the characteristic single- and double-shelled particles may not be readily apparent. Comparison of novel rotaviruses in serological tests has revealed the existence of at least six rotavirus serogroups, A to F, with the original rotaviruses belonging to group A. As with @entity7414 , viruses from different animal species, including @entity1 , can belong to the same serogroup. A further point of difference between novel and @entity7414 is their genome profiles, which lack the triplet of segments in the 7-8-9 region of @entity7414 . This is a useful diagnostic aid. Novel rotaviruses have been found in farm animals and @entity1 . They can cause @entity1681 experimentally and infect villus enterocytes. In @entity1573 , @entity233 , @entity742 and @entity1707 the viruses and/or antibody to them are commonly found, in association with either @entity4092 . In @entity1 one type of novel virus has emerged as a cause of severe @entity66 in adults. The possible reasons for the relatively recent discovery of the novel rotaviruses are discussed.
