Disease-Resistant Bull Is Cloned
From Times Wire Reports
Scientists at Texas A&M; University in College Station unveiled a disease-resistant black Angus bull, saying it could lead to safer beef and more efficient ranching worldwide. The month-old calf, called Bull 86 Squared, was cloned from genetic material frozen 15 years ago from Bull 86. That animal, which died of old age in 1997, was naturally resistant to brucellosis, tuberculosis and salmonellosis--all of which can be passed on to humans through uncooked beef, unpasteurized milk or contamination.
