Bern: Bats in Switzerland harbor viruses from 39 different viral families, some of which have the potential to transmit and cause disease to other animals, including humans. Researchers have claimed this in a new research. Monitoring the viruses that bats harbor in their bodies around the world could improve the understanding and identification of viruses that pose a risk to humans and the world better prepared for another such pandemic. can prepare.

In some past research or studies, bats in many different countries have been investigated for different types of viruses, but so far no study has focused on Switzerland. However, now researchers from the University of Zurich have tested the virus on more than 7,000 bats living in Switzerland. These bats belong to 18 species of stable and migratory bats. Specifically, they analyzed the DNA and RNA sequences of viruses found in samples from bats collected from organs, faeces, or the places they excrete.

Genomic analysis revealed the presence of 39 different families of viruses, with 16 families previously found to be able to infect other arteries (vertebrae) and therefore potentially transmit to other animals or humans. Further analysis of this at-risk virus revealed that one of the bat colonies studied harbored the near-complete genome of a virus known as a coronavirus (CoV) related to Middle East respiratory syndrome (MERS). .

While the virus related to MERS-CoV is not known to cause disease in humans, MERS-CoV has been responsible for an epidemic in 2012. These findings have been published in the open-access journal PLOS ONE. Isabel Hardmeier from the Institute of Virology, said metagenomic analysis of bats endemic to Switzerland reveals widespread virus genome diversity. Virus genomes of 39 different virus families have been detected, 16 of which are known to infect arteries, including coronaviruses, adenoviruses, henipaviruses, rotaviruses A and H, and parvoviruses.

The researchers concluded that genomic analysis of bat stool samples could be a useful tool for continuous monitoring of viruses transmitted from bats, including the MERS-CoV-related virus. This type of tracking can potentially detect the accumulation of viral genetic mutations that may increase the risk of transmission to other animals, allowing earlier detection of viruses that pose a threat to humans.

We already have some known examples of disease-causing viruses being transmitted directly from bats to humans. Some viruses found in bats can be easily transmitted to other animals and can even spread to humans. The virus behind the ongoing Covid-19 pandemic is SARS-CoV-2, which is believed to be the virus that caused the coronavirus pandemic and has the potential to spread from bat to animal before infecting humans. Chances are also being raised.
