National Reference Laboratory for SARS-CoV-2 infections in animals

Information of the FLI on the current SARS-CoV-2 Situation

Coronavirus

The coronavirus SARS-CoV-2, which was first detected in 2019, spread worldwide from 2020 onwards, causing mild to fatal illness in people in all countries of the world. The most likely starting point of the pandemic was transmission from animals (initially probably bats) to humans. In the course of the massive pandemic, it eventually spread to other animal species, some of which live in the direct vicinity of humans. Therefore, animal studies on the susceptibility of farm animals and pets were carried out at the Friedrich-Loeffler-Institut at the beginning of the pandemic. These showed that not all animal species are equally susceptible to the virus. An up-to-date overview of the occurrence and susceptibility of different species can be found on the website of the World Organisation for Animal Health (OIE) (Link to PDF).

Therefore, in July 2020, the obligation to report infections of animals with the novel coronavirus SARS-CoV-2 was introduced in Germany. The National Reference Laboratory for SARS-CoV-2 infections in animals has validated methods for molecular and serological diagnostics of samples collected in connection with SARS-CoV-2. In addition to sensitive and specific in-house methods, commercially available tests are also used for the respective applications. Furthermore, the NRL participates in national and international ring tests, organizes national ring trials, serves as a contact for the veterinary testing laboratories of the countries and conducts research on the occurrence, diagnostics, pathogenesis, therapy, control and immunoprophylaxis of SARS-CoV2 infections in animals.
