The disease was initially known as jaagsiekte [jɑːχˈsiktə], a word derived from Afrikaans, meaning "chasing sickness", so called because animals are in respiratory distress as if they are out of breath from being chased. [6] It has also been known as sheep pulmonary adenomatosis and ovine pulmonary carcinoma. [7]
JSRV is the virus that is the cause of the contagious lung tumors in sheep called ovine pulmonary adenocarcinoma (OPA). The disease has also been called "jaagsiekte", after the Afrikaans words for "chase" (jaag) and "sickness" (siekte), to describe the respiratory distress observed in an animal out of breath from being chased, indicating the breathing difficulty experienced by infected sheep.
The front teeth are then gradually lost as sheep age, making it harder for them to feed and hindering the health and productivity of the animal. For this reason, domestic sheep on normal pasture begin to slowly decline from four years on, and the life expectancy of a sheep is 10 to 12 years, though some sheep may live as long as 20 years.

The other is the fact that the first sign may be a life-threatening allergic reaction known as anaphylaxis (think: throat-swelling, difficulty breathing) in people who develop the condition, often ...
Tumors form in nose and are contagious. ENTV targets the respiratory system in ovine, specifically the upper-airway epithelial cells. [6] Oncogenesis occurs in the nasal turbinate cells [8] A typical oncogenic virus will cause a mutation in a host cell, causing the transformation of host cells from a protooncogene into an oncogene.

1949. Overall life expectancy: 68 Women: 70.7 Men: 65.2 1949 marked the first year women’s life expectancy eclipsed 70 — a milestone men would not reach for another three decades.
An aging-associated disease (commonly termed age-related disease, ARD) is a disease that is most often seen with increasing frequency with increasing senescence. They are essentially complications of senescence, distinguished from the aging process itself because all adult animals age ( with rare exceptions ) but not all adult animals ...
