Short incubation periods of atypical H-type BSE in cattle with EK211 and KK211 prion protein genotypes after intracranial inoculation

open access: yesFrontiers in Veterinary Science, 2023
In 2006, a case of atypical H-type BSE (H-BSE) was found to be associated with a germline mutation in the PRNP gene that resulted in a lysine substitution for glutamic acid at codon 211 (E211K). The E211K amino acid substitution in cattle is analogous to E200K in humans, which is associated with the development of genetic Creutzfeldt-Jakob disease (CJD)

Absence of classical and atypical (H- and L-) BSE infectivity in the blood of bovines in the clinical end stage of disease as confirmed by intraspecies blood transfusion

open access: yesJournal of General Virology, 2021
While the presence of bovine spongiform encephalopathy (BSE) infectivity in the blood of clinically affected sheep has been proven by intraspecies blood-transfusion experiments, this question has remained open in the case of BSE-affected cattle. Although the absence of infectivity can be anticipated from the restriction of the agent to neuronal tissues

Emergence of a novel bovine spongiform encephalopathy (BSE) prion from an atypical H-type BSE [PDF]

open access: yesScientific Reports, 2016
AbstractThe H-type of atypical bovine spongiform encephalopathy (H-BSE) was serially passaged in bovinized transgenic (TgBoPrP) mice. At the fourth passage, most challenged mice showed a typical H-BSE phenotype with incubation periods of 223 ± 7.8 days.

Experimental Challenge of Cattle with German Atypical Bovine Spongiform Encephalopathy (BSE) Isolates

Journal of Toxicology and Environmental Health - Part A: Current Issues, 2011
For almost two decades after the discovery of the first bovine spongiform encephalopathy (BSE) case, it was generally accepted that only one BSE strain existed globally. However, in 2004, two novel BSE forms (L-type and H-type) were separately identified in two different European Member States, forms that differed from the classical (C-type) form by ...

Atypical L-Type Bovine Spongiform Encephalopathy (L-BSE) Transmission to Cynomolgus Macaques, a Non-Human Primate

open access: yesJapanese Journal of Infectious Diseases, 2011
A low molecular weight type of atypical bovine spongiform encephalopathy (L-BSE) was transmitted to two cynomolgus macaques by intracerebral inoculation of a brain homogenate of cattle with atypical BSE detected in Japan. They developed neurological signs and symptoms at 19 or 20 months post-inoculation and were euthanized 6 months after the onset of ...

Third atypical BSE case in Great Britain with an H‐type molecular profile

Veterinary Record, 2009
First identified in Great Britain in 1986 ([Wells and others 1987][1]), bovine spongiform encephalopathy (BSE) was subsequently detected in many other countries worldwide. An abnormal protease-resistant protein, termed prion or PrPres, derived from a post-translational change of a normal ...

Atypical scrapie cases in Germany and France are identified by discrepant reaction patterns in BSE rapid tests

Journal of Virological Methods, 2004
The intensified surveillance of scrapie in small ruminants in the European Union (EU) has resulted in a substantial increase of the number of diagnosed cases. Four rapid tests which have passed the EU evaluation for BSE testing of cattle are also recommended currently and used for the testing of small ruminants by the EU authorities.

Comparison of mRNA expression levels of selected genes in the brain stem of cattle naturally infected with classical and atypical BSE

Brain Research, 2010
Since 2004 cases of atypical bovine spongiform encephalopathy (BSE) in older cattle are recorded on the basis of aberrant glycoprofiles of prion protein resistant to proteolysis (PrP(res)). The nature of those types of PrP(res) is still not fully understood but the epidemiological data indicate that their occurrence is rare.

Lack of Evidence for Transmission of Atypical H-Type Bovine Spongiform Encephalopathy Prions (H-BSE Prions) by Intracranial and Oral Challenges to Nonhuman Primates

Microbiology and Immunology
ABSTRACTBovine spongiform encephalopathy (BSE) is a prion disease in cattle caused by classical‐type (C‐), L‐type (L‐), or H‐type (H‐) BSE prions. While C‐BSE prions are zoonotic agents responsible for variant Creutzfeldt–Jakob disease, L‐ and H‐BSE prions are believed not to be connected to human prion diseases.
