چکیده انگلیسی
In sheep infected experimentally with the bovine spongiform encephalopathy (BSE) agent, amplification of infectivity in peripheral organs during early preclinical stages is thought to contribute to high titres of the agent being detected in blood, with subsequent haematogenous neuroinvasion through the circumventricular organs (CVOs). In contrast, little disease-associated prion protein (PrPd) or infectivity is detected in the peripheral tissues of cattle during the preclinical and clinical stages of BSE. The aim of this study was to investigate immunohistochemically the role of haematogenous neuroinvasion in cattle with spontaneously arising and experimentally induced BSE. There was almost complete absence of PrPd in the peripheral organs of BSE infected cattle. Additionally, there was minimal involvement of the CVOs during preclinical disease and there was progressive caudorostral accumulation of PrPd in the brain. These findings do not support haematogenous neuroinvasion in the bovine disease.
