The immune system fights viruses with peptides. Now, scientists have treated animal models of herpes with synthetic peptide mimics known as peptoids. These molecules could one day cure or prevent many kinds of infections, including COVID-19. They will present their results at ACS Fall 2021.
Group B Streptococcus (GBS) bacteria are a common cause of blood infections, meningitis and stillbirth in newborns. Now, researchers have discovered that sugar molecules in human milk can prevent GBS infection in human cells and pregnant mice. They will present their results at ACS Fall 2021.
A world-first study led by the University of South Australia has found that cancer patients receiving chemotherapy intravenously have more than double the risk of developing a blood clot or thrombosis if the vein is too small and the catheter occupies more than 45 per cent of the vein.

New Brunswick, N.J. (April 6, 2021) – Rutgers University–New Brunswick microbial oceanographer Kay D. Bidle is available for interviews on the persistent and profound impact of viral infections on algae in the oceans. These infections influence the Earth’s carbon cycle, which helps…
Many people reuse masks and other face coverings many times without sanitizing them. That is likely because current sanitization methods can be cumbersome. A new device using a hanging rack and UV-C light can sterilize up to six masks and other items simultaneously and quickly, killing bacteria, yeasts, mold spores, and viruses. This device has shown its efficacy against pathogens including the highly-contagious E-coli, which was eradicated in about one minute.
To fight antibiotic resistance more antimicrobials are needed to treat bacterial biofilms, which protect an infection from antibiotics
Using flow visualization of emulated coughs and sneezes, researchers assessed the efficacy of facemasks in obstructing droplets. Loosely folded facemasks and bandana-style coverings provide minimal stopping-capability for the smallest aerosolized respiratory droplets. Well-fitted homemade masks with multiple layers of quilting fabric, and off-the-shelf cone style masks, proved to be the most effective in reducing droplet dispersal. Importantly, uncovered coughs were able to travel noticeably farther than the currently recommended 6-foot distancing guideline. Without a mask, droplets traveled more than 8 feet.
In the future, robots could take blood samples, benefiting patients and healthcare workers alike. A Rutgers-led team has created a blood-sampling robot that performed as well or better than people, according to the first human clinical trial of an automated blood drawing and testing device.
A Rutgers-led team has developed a tool to monitor influenza A virus mutations in real time, which could help virologists learn how to stop viruses from replicating. The gold nanoparticle-based probe measures viral RNA in live influenza A cells, according to a study in The Journal of Physical Chemistry C. It is the first time in virology that experts have used imaging tools with gold nanoparticles to monitor mutations in influenza, with unparalleled sensitivity.
Bacteria are becoming increasingly resistant to antibiotics. A major cause is their overuse in both humans and animals. At the same time, a lack of financial incentives is setting back efforts to discover new classes of antibiotics. The problem is both global and local, and without new initiatives, many common medical conditions could become deadly once again.
Study shows measles wipes out 20 to 50 percent of antibodies against an array of viruses and bacteria, depleting a child’s previous immunity
Measles-ravaged immune system must “relearn” how to protect the body against infections
Study details mechanism and scope of this measles-induced “immune amnesia”
Findings underscore importance of measles vaccination, suggesting those infected with measles may benefit from booster shots of all previous childhood vaccines
– Old lungs are not as capable as young lungs of fighting off an infection of the bacteria that causes tuberculosis (TB), placing seniors at a greater risk of developing TB. The microbe that causes this infectious disease, Mycobacterium tuberculosis (Mtb), currently kills more people in the world than any other pathogen. Texas Biomed researchers published an article in the Journal of Infectious Diseases in July 2019. The study details an experiment that took place in vitro (in the lab) and in vivo (in animals) that showed fluid in the lining of the lungs plays a big role in the elderly’s susceptibility to infection with the bacterium Mtb.
