Improved COVID-19 vector vaccine candidate (August 2nd, 2022)

In response to the SARS-CoV-2 pandemic, numerous research projects have been launched to develop vaccines against this emerging pathogen. In a recent publication in the Nature portfolio journal “npj vaccines”, scientists at the Institute of Virology and Immunology (IVI) and the University of Bern report on a Vesicular Stomatitis Virus (VSV)-vectored COVID-19 vaccine candidate. Their work shows that intramuscular immunization of mice with VSV-vectored COVID-19 vaccines is inducing strong antibody responses against the SARS-CoV-2 spike protein only if the vector has been complemented with the VSV glycoprotein G.

World Rabies Day 2021 (Sept 28th, 2021)

Rabies is fatal for both humans and animals and causes an estimated 59,000 human deaths each year, mostly in children in developing countries. Around 99 percent of human cases are due to bites by infected dogs. Switzerland has made major efforts to combat this disease and with great success, as it has been officially rabies-free since 1999. Maintaining this status is a daily challenge. If a case of rabies is suspected, prompt action is vital to protect potentially exposed humans against this deadly zoonosis

Earliest report worlwide of atpyical porcine pestivirus (APPV) in Switzerland (July 17th, 2019)

Using a newly developed RT-PCR assay, we showed that APPV, first described in the US in 2015, is widely present in Switzerland at least since 1986, currently the earliest report worldwide. With approx. 10%, the virus prevalence is surprisingly high in young animals at slaughter. Sequencing of a number of virus samples obtained revealed that the virus strains circulating in Switzerland differ considerably from isolates described worlwide. Obviously, APPV has been circulating within the Swiss pig population for many decades without any entry of virus strains from abroad

Bat influenza viruses differ from conventional influenza viruses in the way they enter the host (February 22nd, 2019)

Bat influenza A viruses have only recently been isolated in South American fruit-eating bats. It became rapidly evident that these viruses differ from conventional influenza A viruses in many aspects. For example, they do not bind to sialic acid residues, the canonical influenza A virus receptor, and they do not encode a sialidase, the characteristic receptor-destroying enzyme of influenza A viruses. An international consortium of scientists from Switzerland (Zürich, Bern), Germany (Freiburg, Greifswald), and the United States of America (New York City) have now identified the MHC class II protein complex as essential entry factor for bat influenza A viruses in multiple species.
