NewsStudy reveals how bacteria assemble their envelope
Researchers have discovered a key process for how the outer membrane of gram-negative bacteria attaches to the cell wall, advancing the understanding of how these bacteria frequently manifest resistance to antibiotics.

NewsBiochar may help stop antibiotics from escaping through hidden soil highways
A new study reveals that biochar can do more than simply trap pollutants. It may actively redirect antibiotic movement in structured soils, helping reduce the risk of contamination in nearby water systems.

NewsNew antibiotic attacks bacteria in never-before-seen way
Scientists have discovered a new antibiotic that works in a never-before-seen way and may be the next frontliner in the fight against drug-resistant superbugs.

NewsThe evolution of individual species can shape entire species communities
A study demonstrated that the evolution of a single species can alter the composition of an entire species community. The study monitored a microbial community composed of 23 bacterial species for four years. Researchers analysed the community’s species composition and changes in bacterial genomes.

NewsAntibiotics drive resistance in waterways - even after they break down
Antibiotics continue to drive resistance to bacteria, even after they are broken down in wastewater treatment plants and discharged into rivers and seas, new research published on World Oceans Day has shown for the first time.

NewsShiga-producing E. coli infections are becoming more resistant to antibiotics
A new study indicates resistance to antimicrobial agents is rising among human infections with Shiga toxin–producing Escherichia coli bacteria.

NewsIron-modified biochar turns soil oxygen into a cleaner for antibiotic pollution
Antibiotic residues in agricultural soils are an emerging environmental concern, with potential impacts on soil health, crop safety, and the spread of antimicrobial resistance. A new study reports on an iron-modified biochar that helps soil use its own oxygen and iron chemistry to break down sulfamethoxazole.

NewsResearchers discover a new antibiotic — and a new way to kill drug-resistant bacteria
Researchers have discovered a new antibiotic that kills some of the world’s most dangerous and drug-resistant bacteria by targeting a previously unknown vulnerability. Manikomycin has shown early effectiveness against priority pathogens including Salmonella, E. coli, and Klebsiella.

NewsAntibiotics for common sore throats have very limited effect on Strep spread
Antibiotics for sore throats have hardly any preventive effect against serious streptococcal infections in the population, according to a study. Instead, healthcare needs to quickly recognize warning signs of a serious infection.

NewsResearchers evaluate NASA medication storage protocols
Researchers evaluated NASA’s medication handling practices, which currently call for removing medications from their original packaging and storing them in resealable plastic bags. The investigation found that active pharmaceutical ingredients degrade at a higher rate when stored in bags.

NewsPost-discharge antibiotics may offer limited benefit after pediatric appendicitis
Acute appendicitis is one of the most common surgical emergencies among children, and complicated acute appendicitis (CAA), including perforated or gangrenous disease, carries a higher risk of infection and longer hospitalization. While intravenous antibiotics during hospitalization are standard practice, the role of oral home antibiotics (OHA) after discharge remains controversial. ...

NewsNew antibiotic design could help treat drug-resistant infections
A new study has shown that antibiotics can be chemically redesigned so they are less easily removed by efflux pumps. This allows the antibiotic to remain inside the bacterial cell at higher concentrations, restoring its ability to kill bacteria even when resistance mechanisms are present.

NewsWhy antibiotics fail against a common dental implant disease
A study of peri-implantitis found that bacteria corrode implants, causing them to shed microscopic titanium particles into the surrounding tissue. Those particles hijack the immune cells sent to clear the infection and lock them into a state of inflammation that destroys the jawbone they are supposed to protect.

NewsScientists fight antimicrobial resistance by treating diseases with human antibodies
In a review, researchers highlight the promise of using human monoclonal antibodies (mAbs) to treat patients more effectively and tackle AMR. They say AMR needs to be addressed with multiple and differentiated strategies, and vaccines and mAbs are the most promising tools.

NewsStudy reveals “bet-hedging” strategy that helps gut bacteria survive and recover
Researchers have discovered that many gut bacteria use a flexible survival strategy to withstand disruptions such as antibiotics and diet changes. Microbes can switch between functional states, rather than relying solely on genetic mutations, to try to survive shifting conditions.

NewsAntibiotic proves ineffective in treating wheezing in young children in the emergency room
A study has shown that giving the antibiotic azithromycin did not help preschool children seen in the hospital emergency room with bouts of severe wheezing. It provides more definitive answers to longstanding questions and inconclusive studies about the role of some types of bacteria in wheezing and asthma.

NewsBacteria may hold a cancer treatment clue
A review argues that tumors with reproducibly poor prognosis outcomes may share an overlooked feature: bacterial infection within the tumor microenvironment. These bacteria may weaken treatment by altering local immunity, damaging tissue structure, and even inactivating chemotherapeutic drugs.

NewsWine’s leftovers could help wean chicken farms off antibiotics
Every year, millions of gallons of wine are pressed, leaving behind a mountain of pulpy residue that wineries struggle to dispose of. Now, researchers say this overlooked byproduct could serve as a replacement for the antibiotics routinely added to chicken feed.

NewsPenn researchers create AI tool to speed antibiotic discovery
Researchers have developed a novel, AI-powered method for turning promising but imperfect antibiotic candidates into more potent ones. ApexGO starts with a small number of imperfect candidates and improves them step by step, using a predictive algorithm to evaluate each modification and guide the next.

NewsNew study shows cranberry juice may boost UTI antibiotics
Researchers recently exposed lab-grown strains of pathogenic Escherichia coli to cranberry juice. Preliminary findings suggest that compounds in the juice re-sensitize resistant strains to antibiotic treatment.
