Colistin-resistant E. coli gains resistance to innate human immunity

Researchers from the University of Oxford, U.K., have investigated the evolution of antibiotic resistance properties of antimicrobial peptides (AMPs). In the paper “The evolution of colistin resistance increases bacterial resistance to host antimicrobial peptides and virulence,” published in eLife, researchers detail a disturbing discovery of how a specific type of antimicrobial agent, colistin, could be training E. coli and possibly other pathogens to evade the human immune system better.

Pilot program in California shows dogs able to accurately sniff out COVID-19

A team of medical researchers from the California Department of Public Health, Kaiser Permanente, and Early Alert Canines, has conducted a pilot program to look into the possibility of using dogs to sniff out COVID-19 infections in students. In their paper published in the journal JAMA Pediatrics, the group describes their testing setup using trained dogs in both public and private schools and what they learned from the experience.
