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.

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.

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.

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.

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.

NewsAdd some spice: Curcumin helps treat Mycobacterium abscessus
Researchers have found that adding curcumin boosts the efficacy of bedaquiline, an antimycobacterial used to treat tuberculosis, in combating M. abscessus infections. Curcumin is the compound that gives turmeric its characteristic bright orange color.

NewsHelicobacter pylori treatment practices in the Asia-Pacific region
Researchers conducted an online survey of clinicians in the Asia-Pacific region to investigate treatment policies for H. pylori and confirmed that there is a growing consensus of the importance of primary and secondary prevention against H. pylori.
-
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.

NewsGenetic resistance factors and antimicrobial resistance phenotypes in methicillin-resistant Staphylococcus aureus isolates of animals and humans
A new study identified three functional protein families in MRSA, through sequencing, that confer extensive antibiotic resistance independent of the known antibiotic resistance determinants, mecA and mecC.

NewsA review of Clostridioides difficile infection and treatments
<i>Clostridioides difficile</i> is a serious nosocomial infection that could cause from mild diarrhea to fatal colitis. Here presents a general overview that describes the current and emerging treatment practices for the prevention of <i>Clostridioides difficile</i> infection and its recourrences.

NewsClove oil yields new Pickering emulsion formulation with enhanced antibacterial properties
Researchers developed a sustainable Pickering emulsion using carbon quantum dots (CQDs), promising solid particles for food applications, derived from clove essential oil residue. They found that CQDs with 40% ethanol demonstrated the highest emulsifying efficacy.

NewsPurified immunoglobulin F(ab′) 2 prevents lethal staphylococcal enterotoxin B intoxication in mice and rhesus monkeys
Purified F(ab′)2 fragments are an effective antidote to lethal SEB doses in mice and rhesus monkeys, and therefore might be a favorable candidate for treating patients with severe SEB intoxication, a new study suggests.
-
NewsAntimicrobial resistance in soil bacteria without the use of antibiotics
Overuse of antibiotics is currently the primary reason for the rise of antimicrobial resistance (AMR), but researchers have shown that AMR can be found in soil bacterial communities due to microbial interactions too, driven by a species of predatory bacteria.

NewssiRNA-AGO2 complex inhibits bacterial gene translation: a novel therapeutic strategy for superbug infection
Scientists have demonstrated that exosomes can serve as delivery vehicles to introduce AGO2-loaded siRNA into the cytoplasm of bacteria, and in turn down-regulated gene expression of the mRNA that shares sequence complementarity to the siRNA.

NewsNovel insights into Candida glabrata in pregnant women’s reproductive tracts in Hainan
A study of Candida glabrata in pregnant women with vaginal discomfort at Haikou Maternal and Child Health Hospital found that 64.5% of the 594 yeast isolates (383 isolates) showed resistance (R) or intermediate (I) phenotypes to at least one of four commonly used antifungals.
