ovine lentivirus There are two diseases associated with lentiviruses in sheep, now considered to be the same or very closely related viruses with species name Visna/maedi virus in the genus Lentivirus. In 1933, 20 Karakul sheep were imported into Iceland from Germany, and within 2 years the two diseases visna (meaning wasting) and maedi (meaning dyspnea) emerged and became a major problem to the sheep industry in Iceland. Following a massive slaughter of some 600 000 sheep, the disease was declared eradicated from Iceland in 1965, though it continues in some other European countries and in the USA where it is called progressive pneumonia of sheep. See Visna/maedi virus.

Ovine papillomavirus (OPV) A species in the genus Papillomavirus. There are two genotypes. Papillomas occur in some flocks but are not common. They may become malignant. Virus inoculated into the skin of sheep produces papillomas. Cattle and goats are resistant, but slowly growing fibromas are produced in neonatal hamsters. Causes a cutaneous fibropapilloma of sheep, found on the eyelid, muzzle, vulva and legs. Synonym: sheep papillomavirus.
