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.

NewsStudy identifies viruses in red tide blooms for the first time
A new study identifies viruses associated with Karenia brevis, the single-celled organism that causes red tide. By testing water samples collected from red tide blooms, the researchers found several viruses in blooms — including one new viral species.

NewsNew study reveals high levels of fusarium mycotoxins in seized cannabis from Arizona and California
A recent study has uncovered alarming levels of Fusarium mycotoxins in illicit cannabis samples seized in Arizona and California. 16% of the 118 samples tested positive for harmful mycotoxins, posing potential health risks to consumers and highlighting the unregulated and dangerous nature of black-market cannabis.

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.

NewsCOVID-19 pandemic worsened mother and infant birth outcomes
Mothers who became pregnant after the start of the pandemic, those who experienced moderate-to-severe infections during pregnancy, and those who had infections during the third trimester were more likely to have adverse outcomes.
