A paramyxovirus was discovered by chance during the primary culture of grey squirrel (Sciurus carolinensis) kidney cells from the UK. Amplification, sequencing and phylogenetic analysis of part of the genome encoding a region of the RNA polymerase (L gene) confirmed that the virus was a member of the Paramyxovirinae subfamily, but that it did not partition with any of the currently recognised paramyxovirus genera and instead segregated with the unclassified rodent viruses, J-virus, Beilong virus and Tailam virus as well as paramyxoviruses recently detected in rodents in Africa. A subsequent examination of kidney samples from red squirrels (Sciurus vulgaris) revealed that they too harboured a paramyxovirus, but sequence analysis of the corresponding region of the L gene revealed that it was approximately 67% identical to the grey squirrel virus, suggesting the presence of a second species of virus. In addition, one of the red squirrels examined harboured a second virus with approximately 69% identity to the grey squirrel virus, but only approximately 63% identity to the other red squirrel viruses, signifying the presence of a third species of paramyxovirus. In a sample of 22 red and grey squirrels 68% of those examined were found to harbour virus suggesting that paramyxovirus infection in squirrels may be common within the UK.
