Genetic Characterization and Classification of Human and Animal Sapoviruses
Sapoviruses (SaVs) are enteric caliciviruses that have been detected in multiple mammalian species, including humans, pigs, mink, dogs, sea lions, chimpanzees, and rats. They show a high level of diversity. A SaV genome commonly encodes seven nonstructural proteins (NSs), including the RNA polymerase protein NS7, and two structural proteins (VP1 and VP2). We classified human and animal SaVs int...
متن کاملAntigenic Diversity of Human Sapoviruses
Sapovirus (SaV) is a causative agent of gastroenteritis. On the basis of capsid protein (VP1) nucleotide sequences, SaV can be divided into 5 genogroups (GI-GV), of which the GI, GII, GIV, and GV strains infect humans. SaV is uncultivable, but expression of recombinant VP1 in insect cells results in formation of viruslike particles (VLPs) that are antigenically similar to native SaV. In this st...
متن کاملIntergenogroup Recombination in Sapoviruses
Sapovirus, a member of the family Caliciviridae, is an etiologic agent of gastroenteritis in humans and pigs. Analyses of the complete genome sequences led us to identify the first sapovirus intergenogroup recombinant strain. Phylogenetic analysis of the nonstructural region (i.e., genome start to capsid start) grouped this strain into genogroup II, whereas the structural region (i.e., capsid s...
متن کاملThe Influence of Recombination on Human Genetic Diversity
In humans, the rate of recombination, as measured on the megabase scale, is positively associated with the level of genetic variation, as measured at the genic scale. Despite considerable debate, it is not clear whether these factors are causally linked or, if they are, whether this is driven by the repeated action of adaptive evolution or molecular processes such as double-strand break formati...
متن کاملphylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
