NewsDeadly bacteria developed the ability to produce antimicrobials and wiped-out competitors
A drug-resistant type of bacteria that has adapted to health care settings evolved in the past several years to weaponize an antimicrobial genetic tool, eliminating its cousins and replacing them as the dominant strain.

NewsHidden threat: The evolving fungus that spreads through cats and humans
Researchers have developed a better understanding about the molecular basis of the Sporothrix species in virulence and evolution, amid the largest sporotrichosis epidemic in Brazil. The identification of the genetic markers helps to enhance fungal surveillance and strengthen disease control.

NewsLong COVID could be causing huge economic burden annually
Behind the healthcare burden from long COVID, a study has also uncovered the economic burden of those who are more likely to suffer from long COVID through a computer simulation model of long COVID probabilities and the accompanied productivity loss.

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.

NewsUnknown microorganisms used marble and limestone as a habitat
Research work has revealed unusual structures that are probably due to the activity of an unknown microbiological life form. Unusually small burrows, i.e., tiny tubes that run through the rock in a parallel arrangement from top to bottom, were discovered in marble and limestone of the desert areas of Namibia, Oman, and Saudi Arabia.

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.

NewsStudy yields new data on Mpox vaccine effectiveness in people with HIV
A new study has found that a single dose of the Imvanex vaccine provides protection against Mpox with 84% effectiveness. For people with HIV, however, a single dose of the vaccine fails to offer sufficient protection. All at-risk groups, especially people with HIV, should receive the second dose of the vaccine as recommended.

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.
