The enzootic nasal tumor virus of the betaretrovirus genus is a carcinogenic retrovirus that causes enzootic nasal adenocarcinoma in sheep and goats.[1] Strain ENTV-1 is found in sheep and strain ENTV-2 is found in goats.[2][3] The virus causes tumor growth in the upper nasal cavity and is closely related to JSRV which also causes respiratory tumors in ovine.[4] The disease, enzootic nasal adenocarcinoma is common in North America and is found in sheep and goats on every continent except New Zealand and Australia.[5] There are more than 27 betaretroviruses similar to ENVT and JSRV in the ovine genome.[6][7] In the future, research on ENTV may become important in studying viruses that cause human lung cancer.[8]
