Did dolly the sheep die from streptococcus pneumonia?
Dolly the sheep did not die from a sickness. She was staying at a farm and had been bred to a normal ram to test her fertility. She had one lamb that she raised on her own, but in the fall when the farm was sending sheep to slaughter, she and her lamb somehow ended up on the trailer What?? Do not believe anyone on these websites. None of the above is true. Dolly the sheep was euthanised on Feb 14th,2003 from a progressive lung disease, aged 6. The disease is common is sheep and wasnt a result from cloning.
Why did Dolly die?
Referring to Dolly the Sheep: On February 14 , 2003, Dolly was euthanised because of a progressive lung disease. A Finn Dorset such as Dolly has a life expectancy of around 11 to 12 years, but Dolly lived to be only six years of age. A post-mortem examination showed she had a form of lung cancer called Jaagsiekte that is a fairly common disease of sheep and is caused by the retrovirus JSRV. Roslin scientists stated that they did not think there was a connection with Dolly's being a clone, and that other sheep in the same flock had died of the same disease. Such lung diseases are a particular danger for sheep kept indoors, and Dolly had to sleep inside for security reasons. However, some have speculated that a contributing factor to Dolly's death was that she could have been born with a genetic age of six years, the same age as the sheep from which she was cloned. One basis for this idea was the finding that Dolly's telomeres were short, which typically is a result of the aging process. However, the Roslin Institute have stated that intensive health screening did not reveal any abnormalities in Dolly that could have come from advanced aging.
