Although previous research has indicated that the autonomic nervous system (ANS) becomes affected by bovine spongiform encephalopathy (BSE) only after the central nervous system (CNS) has been infected, researchers are now reporting that the ANS may show signs of infection earlier.
The results of a new study published online in the August issue of The American Journal of Pathology indicate that the infection may use another pathway to the brain:
The infection was detected in one animal just 16 months after infection, according to Science Daily.
Typically it takes about 60 months from infection to the first signs of illness.
The researchers studied 56 calves to learn more about the pathogenesis of BSE in the early incubation period.
