Molecular identification of an enterovirus 99 strain in Spain

Enterovirus 99 is a recently described genotype of virus belonging to the species Human enterovirus C. So far, only a few sequences of this enterovirus type have been available. In 2010, during Spanish enterovirus surveillance, an enterovirus 99 strain was found in an acute flaccid paralysis patient. The virus was detected and typed in the clinical samples using molecular methods. Phylogenetic analysis in the 3Dpol region revealed recombination events with other species-C enteroviruses. This is the first finding of this unusual type in Spain.
