NewsResearchers discover Achilles heel of Lyme disease pathogen
Researchers discovered and investigated an unique enzyme used in the pathway specific to Borrelia burgdorferi, the parasite that causes Lyme disease. The enzyme serves as the ideal genus-specific target for therapeutic intervention.

NewsTeam finds regional, age-related trends in exposure to drug-resistant pathogen
A study from 10 US states found drug-resistant Campylobacter jejuni infections were highest in the 20-39 age group and that quinolone-resistant C. jejuni infections increased from 22.6% of those tested in 2013 to 33.54% in 2019. It identified regional differences in C. jejuni resistance to quinolones and six other classes of antibiotics.

NewsHost’s sex plays key role in how gut microbiome evolves with age
Researchers studied how aging affects gut bacteria in a special group of rats generated to have genetic diversity similar to humans. Their research found that both biological sex and mitochondrial DNA—the small set of genes inherited only from mothers—play a key role in how gut bacteria change over time.

NewsLead science organizations affirm vaccine safety amid rising misinformation and declining trust
A unified statement, issued by a coalition of leading scientific and medical organizations, addresses the rise in vaccine misinformation and a decline in trust of science, amidst the outbreaks of preventible infectious diseases. It reassures the current concerns on vaccine safety and emphasizes the importance of vaccinations in public health.

NewsFDA-approved dialysis drug may help fight against antimicrobial resistance
In account of the imminent threat of antimicrobial resistance (AMR), a study revealed that the FDA-approved sevelamer, which is used to treat chronic kidney disease undergoing dialysis, is successful in the removal of other off-target antibiotics (vancomycin and daptomycin) from the gut.

NewsBacteria invade brain after implanting medical devices
Researchers have discovered that bacteria can invade the brain after a medical device is implanted, contributing to inflammation and reducing the device’s long-term effectiveness.
-
NewsScientists discover protein key to bacteria’s survival in extreme environments
A new discovery sheds light on how certain bacteria – including strains that cause food poisoning and anthrax – form spores for survival.

NewsRice research team creates universal RNA barcoding system for tracking gene transfer in bacteria
An interdisciplinary group of researchers at Rice University has developed an innovative RNA “barcoding” method to track gene transfer in microbial communities, providing new insights into how genes move across species.
-
NewsResearchers demonstrate new technique for boosting plant growth with bacteria
A single combined delivery system incorporating multiple active ingredients, including plant growth-promoting bacteria and agrochemicals, is developed to ensure beneficial bacterial survival and improve plant growths.

NewsResearch uncovers new strategy to reduce tissue damage from flesh-eating bacteria
A new study reveals a novel approach to mitigating tissue damage caused by Streptococcus pyogenes, the flesh-eating bacterium responsible for severe infections such as necrotizing fasciitis.
-
NewsCurrent antivirals likely less effective against severe infection caused by bird flu virus in cows’ milk
Scientists found that in a preclinical model, two FDA–approved flu antivirals generally did not successfully treat severe H5N1 infections. Meanwhile, the route of infection, whether through the eye, the nose or the mouth, significantly impacts effectiveness.
