NewsResearch team awarded NIH grant to study early immune determinants of human tuberculosis infection
A research team was awarded a 5-year, $3.8 million grant to study early immune responses in the lung and how they influence tuberculosis infection outcomes. The program focuses on how lung immune cells called macrophages influence the earliest stages of tuberculosis infection.

NewsHow are chloroplasts communicating with the nucleus? Bacterial enzymes show the way
By utilizing bacterial enzymes that cleave heme molecules at different sites, researchers have developed a method to dissect phytochrome-dependent light and heme retrograde signaling pathways in plants, which have previously been difficult to discuss separately.

NewsDrug-resistant bacteria found in homes from sewage overflow
A new study shows that sewage overflows in homes can expose people to bacteria that can make them sick, including antibiotic-resistant and multidrug resistant bacteria which can make infections difficult to treat.

NewsDentistry researchers testing oral bacteria transplants to cure bad breath
To rebalance the oral microbiome and cure chronic halitosis, researchers are embarking on a first-of-its-kind experiment. These clinical trials transplant bacteria and other microbes from healthy donors into patients with halitosis. If successful, the healthy microbiota will crowd out the bad and patients’ bad breath will improve.

NewsFever and chills can make respiratory diseases more contagious
A new study reveals that when the difference between body temperature and the ambient temperature is greater, the clouds of particles generated by coughing or sneezing disperse more and maintain a higher concentration.

NewsResearchers combine bacteria and viruses to demonstrate a new way to fight cancer
Researchers have designed non-toxic Salmonella bacteria to deliver viruses that are safe to humans but potent against liver and pancreatic cancer tumors. Animal models treated with this combination of bacteria and viruses saw almost all their tumors eliminated and lived significantly longer.

NewsThe road to better health requires a map of the microbes in your mouth
Different parts of your mouth have entirely different bacterial communities, reveals a new microbial map. Researchers believe mapping these microbial niches will provide a census of the good bacteria present in the mouth and help to develop targeted therapies, such as probiotics, to maintain oral health and prevent disease.

NewsResearcher investigates how a bioengineered peptide can break through harmful bacterial ‘fortresses’ and curb severe infections
A researcher is refining a powerful therapy for drug-resistant bacteria that pierces the gooey coating that anchors and protects such germs from the drugs we take to kill them. She has found that an antimicrobial peptide naturally found in cows weakens the biofilm defenses of Klebsiella pneumoniae bacteria and destroys it.

NewsScientists map the microbes behind a climate-regulating gas in India’s busiest estuary — a first
When bacteria in the water and sediment break dimethylsulfoniopropionate down, they release dimethylsulfide (DMS), a gas that drifts into the atmosphere and helps form clouds by seeding cloud condensation nuclei. A new paper reports the first-ever study of DMSP concentrations and the bacteria that degrade it along the entire length of the Cochin Estuary.

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.

NewsResearcher studying probiotics to fight acid reflux and esophageal cancer
Patients with acid reflux, which occurs when stomach acid pushes up into the esophagus, know the symptoms all too well: heartburn, belching, chest pain and trouble swallowing. Acid reflux also increases the risk of esophageal cancer, but researchers are investigating how a simple probiotic could treat and prevent both conditions.

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 discover how to turn one germ’s drug resistance into an Achilles’ heel
As Mycobacterium tuberculosis mutates to protect itself from rifampicin, it also creates new weak points that other therapies could exploit. A new study shows that the most common rifampicin-resistance mutation slows bacterial RNA polymerase, creating vulnerabilities that future combination therapies may be able to target.

NewsMagnetic biochar gel helps keep arsenic and antimony out of rice
A new study reports a promising strategy for mining-impacted regions: a magnetic silicon-enriched biochar gel that can immobilize both arsenic and antimony in contaminated paddy soil and reduce their accumulation in rice grains.

NewsEU project aims to make climate-neutral plastics and cosmetics using bacteria
A European research team is aiming to revolutionize the chemical industry: as part of the CarboNcare project, scientists are developing bacteria that can produce important chemical base materials from sustainable methanol – thereby replacing fossil resources.

NewsEngineered gut bacteria therapy emerges as scalable potential alternative to fecal microbiota transplants following clinical trial
Researchers have developed a new manufacturing platform for producing targeted mixtures of beneficial gut bacteria, an approach that could help expand access to microbiome-based therapies for patients with recurrent Clostridioides difficile (C. difficile) infection.

NewsRedesigning an elusive bacterial enzyme into an efficient green catalyst
Scientists engineer the CYP107J1 enzyme from Bacillus subtilis into a more practical tool for selective oxidation chemistry.

NewsStarvation triggers reversible epigenetic changes in fish pathogen
What happens to a bacterial pathogen when food runs out—for several months? A new study reveals that Flavobacterium columnare, a deadly aquatic pathogen responsible for columnaris disease in fish, does not change its DNA sequence during prolonged starvation. Instead, it remodels its epigenetic landscape.

NewsProtection for newborns: New treatment aims to prevent meningitis without antibiotics
One of the leading pathogens responsible for meningitis cases in newborn babies is the K1 form of the E. coli bacterium. Now, researchers have developed a triple-pronged approach that seeks to prevent transmission to newborns.

NewsNew study suggests fish gut microbe helps regulate ocean health
New research reveals a potential link between the gut microbes of a fish and global ocean processes, offering new insight into how marine ecosystems help regulate ocean chemistry and the marine carbon cycle.
