It is therefore of obvious concern that the authors at the National Collection of Pathogenic Viruses (NCPV), whilst characterising stocks of rhinovirus from the MRC Common Cold Research Unit, found that five of 22 cell cultures had abnormal cytopathic effects when infected with putative rhinovirus. PCR and sequencing confirmed that four of these putative rhinovirus
