Gene-Edited Calf Shows Resistance to Bovine Viral Diarrhea Virus: Promising Breakthrough in Cattle Health
Groundbreaking Study: Scientists successfully gene-edit a calf to develop resistance against bovine viral diarrhea virus, a major threat to cattle globally.
#01
Persistent Virus: Despite decades of vaccination efforts, controlling the virus remains challenging due to transmission difficulties and ineffective vaccines.
#02
Targeting the Receptor: Researchers modify the virus-binding site on the cellular receptor CD46 to prevent viral infection while maintaining normal bovine functions.
#03
Testing the Concept: Promising results in cell culture lead to editing cattle skin cells and transplanting embryos into surrogate cows to assess virus resistance in live animals.
#04
Healthy Birth: The first gene-edited calf, named Ginger, is born healthy and shows reduced susceptibility to the virus without any adverse health effects.
#05
Continued Monitoring: Scientists will closely observe Ginger's health and her ability to produce and raise her own calves in the future.
Potential Impact: Gene editing offers a new approach to reduce bovine viral diarrhea virus-associated diseases and decrease the need for antibiotics in agriculture.
#07
Secondary Benefits: By reducing viral infections, the risk of secondary bacterial diseases in calves is also expected to decrease.
#08
Promising Breakthrough: The study represents a proof-of-concept, highlighting the potential of gene editing in improving cattle health and welfare.
#09
Future Implications: Further research and development are needed to fully understand the implications and applications of this groundbreaking technique.
