NewsInfectious H5N1 influenza virus in raw milk rapidly declines with heat treatment
The amount of infectious H5N1 influenza viruses in raw milk rapidly declines with heat treatment, but small amounts of infectious virus remain in raw milk samples with high virus levels when treated at 72 degrees Celsius for 15 seconds.

NewsAI enables faster, more effective antibiotic treatment of sepsis
Sepsis is a life-threatening infection complication and accounts for 1.7 million hospitalizations and 350,000 deaths annually in the U.S. Fast and accurate diagnosis is critical, as mortality risk increases up to 8% every hour without effective treatment. Source: Ilanaer42 However, the current diagnostic standard is reliant on ...

NewsUpper surface of coastal waters can accumulate bacteria and antibiotics
Antibiotics in the uppermost water surface, known as the sea surface microlayer, can significantly affect the number of bacteria present and contribute to the adaptation of marine bacteria against widely used antibiotics. In new research presented at ASM Microbe, scientists directly assessed the potential effects of antibiotics ...

NewsPlant bacteria deploy phage elements to wipe out the competition
A new study has found that plant bacterial pathogens are able to repurpose elements of their own phages to wipe out competing microbes, suggesting such elements could someday be harnessed as an alternative to antibiotics.
