Chal­lenging the the­ory of the nar­row host range of phages

Viruses that infect bacteria could one day replace antibiotics because they precisely attack only specific pathogens. Researchers at ETH Zurich are now showing that this is not always the case. This new finding is important ...

Viruses can hitch a ride on bacteria

The interaction of fungi and bacteria in the transport of viruses in the soil ecosystem has been examined by a UFZ research team in a study recently published in The ISME Journal. The scientists showed a novel mechanism of ...

Bacterial viruses: Faithful allies against antibiotic resistance

It is a fact that bacteria are increasingly developing antibiotic resistance. Information campaigns have raised awareness among the general public that the main cause of antibiotic resistance is the high 'selection pressure' ...

Important role of prokaryotic viruses in sewage treatment

Prokaryotic viruses (phages) existing in activated sludge (AS), a biological treatment process widely used in wastewater treatment plants (WWTPs), act to regulate the composition of microbial community in the activated sludge. ...

Fighting viruses with interchangeable defense genes

Bacterial viruses, so-called phages, destroy bacteria. Bacteria are constantly exposed to viral attacks. A research team led by Martin Polz, a microbiologist at the University of Vienna, has now studied how bacteria defend ...

Viruses are both the villains and heroes of life as we know it

Viruses have a bad reputation. They are responsible for the COVID-19 pandemic and a long list of maladies that have plagued humanity since time immemorial. Is there anything to celebrate about them?
