CHOP researchers establish novel approach for developing new antibiotics
(Children's Hospital of Philadelphia) Researchers at Children's Hospital of Philadelphia (CHOP) have developed a novel method for producing new antibiotics to combat resistant bacteria. Through an approach that would target bacteria with an antibiotic that is masked by a prodrug, which the bacteria would themselves remove, the researchers identified a method that would allow for development of new, effective antibiotics that could overcome issues of resistance. The findings were published today in eLife. (Source: EurekAlert! - Infectious and Emerging Diseases)

In vitro Zoo helps in understanding SARS-CoV-2
(University of Bern) A team of researchers from the University of Bern and the Institute of Virology and Immunology (IVI) have used a unique collection of advanced cell culture models of cells lining the airways from various domesticated and wildlife animals to determine which animals are susceptibly to SARS-CoV-2 infection. The team found that SARS-CoV-2 efficiently infected respiratory cells from monkey and cats, and proposes that SARS-CoV-2 surveillance in these animals and its close relatives is necessary.
