Epidemiological comments On July 5th, 2019, the Central Veterinary Laboratory in Algete (National Reference Laboratory for TSEs, accredited under UNE-EN ISO/IEC 17025:2005 standard) received a nerve tissue sample suspected to be infected by bovine spongiform encephalopathy (BSE) from the accredited Regional Laboratory for Animal Health in Lugo, Galicia (official regional laboratory), after a positive result was obtained through a HerdChek BSE-Scrapie Antigen Test Kit (Idexx Laboratories) rapid test. The National Reference Laboratory carried out the confirmation tests authorized according to EU Regulation No. 1148/2014. The selected combined tests were ELISA, carried out by the regional laboratory (HerdChek), and Prionics Check Western Blot, and positive results were obtained for both tests. Afterwards, tests for BSE strain discrimination were carried out through hybrid immunoblotting with antibodies against PrP, confirming atypical BSE (H type strain). The sample was taken within the national TSE surveillance program (sampling of dead or non-slaughtered for human consumption animals over 48 months old). The animal was a crossbred cow born on January 30th, 2001.
