NewsBacteria can deliver on promise of climate-neutral chemicals of the future
To explore the potential of synthetic methylotrophs for the biotechnological production of industrially relevant bulk chemicals, researchers have equipped the bacteria with additional genes for four different biosynthetic pathways.
-
NewsGut microbiota acts like an auxiliary liver
Microbes in the mammalian gut can significantly change their hosts’ amino acid and glucose metabolism, acting almost like an extra liver, according to a new preclinical study.

NewsUndernourished household members at increased risk for developing TB after exposure
Researchers have found that undernourished household contacts are three times more likely to progress to TB disease.

NewsOdor-causing bacteria in armpits targeted using bacteriophage-derived lysin
Researchers analyzed bacterial metabolism and the DNA of skin microflora in armpit fluid samples and found odor-causing precursors along with a proliferation of Staphylococcus hominis bacteria.

NewsPathogens deploy speargun nanomachine to spread unrecognized in the body
Researchers have uncovered a unique tactic certain bacteria use to spread in the body without being detected by the immune system. In their study, they reveal the crucial role of a bacterial nanomachine in this infection process.

NewsImpact of COVID-19-related nonpharmaceutical interventions on diarrheal diseases and zoonotic salmonella
The results showed that while the detection rate of most foodborne pathogens declined in China during the pandemic there was an abnormal increase in the detection rate of non-typhoidal Salmonella.

NewsBlack women hospitalised in USA with blood infection resistant to last-resort antibiotic at increased risk of death
New research finds that the odds of death in black women with a bloodstream infection (BSI) caused by carbapenem-resistant enterobacterales (CRE) was twice that of black men or white women.
-
NewsNew class of antimicrobials discovered in soil bacteria
Scientists have mined Streptomyces for antibiotics for nearly a century, but the newly identified umbrella toxin escaped notice.
-
NewsScientists reveal how soil microbes survive in harsh desert environments
A new study reveals how desert soil bacteria are highly adapted to survive the rapid environmental changes experienced with prolonged droughts followed by sudden bursts of rainfall.

CareersDIY beeswax food wraps could be a lifesaver in conflict regions like Ukraine
Home-made antimicrobial beeswax food wraps containing locally sourced herbs could provide low cost food storage in areas of Ukraine where the power supply has been disrupted by the Russian invasion.

NewsScientists deploy bacteria to detect sake fraud in Japan
Researchers from Japan have identified a novel method to authenticate the source of and differentiate between sake breweries, by measuring the oxygen and nitrogen stable isotopes in nitrates within sake using denitrifying bacteria first.
-
NewsResearchers uncover new reasons to target neutrophils for tuberculosis therapy
Using cell models of infection, scientists examined the cross-talk between two lung immune cells: the macrophage and the neutrophil.
-
NewsDiscovery of bacterial proteins that induce asexual reproduction in insects
From microbes in the human gut to symbiotic algae in coral reefs, research in recent decades has increasingly revealed the pivotal roles that microorganisms (or microbial species) play in shaping the biology of host organisms and of broader ecosystems. For example, some endosymbionts—microbes that live within the cells of a ...

NewsResearchers name worst offenders behind meningitis in babies
Researchers have identified the main types of E. coli bacteria that cause neonatal meningitis, and revealed why some infections recur despite being treated with antibiotics.

NewsImproved oral cholera vaccine achieves WHO PQ
EuBiologics and the International Vaccine Institute (IVI) announced that Euvichol-S, an improved oral cholera vaccine (OCV) developed jointly by EuBiologics and IVI, has achieved World Health Organization prequalification.
-
NewsDeadly bacteria show thirst for human blood
Some of the world’s deadliest bacteria seek out and feed on human blood, a newly-discovered phenomenon researchers are calling “bacterial vampirism”.
-
NewsNanoparticle enhances antibacterial sonodynamic therapy for eradication of Pseudomonas aeruginosa biofilm
A novel ultrasound-launched targeted nanoparticle was developed to universally destroy biofilm, target bacteria, deliver antibiotics, and efficiently kill bacteria via ultrasonic cavitation and antibacterial sonodynamic therapy.
-
NewsResearchers resolve old mystery of how phages disarm pathogenic bacteria
Scientists observed how a phage called PP7 infects Pseudomonas aeruginosa by attaching to the pilus, which then retracts and pulls the phage to the cell surface.
-
NewsAntibiotics aren’t effective for most lower tract respiratory infections
Use of antibiotics provided no measurable impact on the severity or duration of coughs even if a bacterial infection was present, finds a large, prospective study of people who sought treatment for lower-respiratory tract infections.

NewsStudy reveals new approach for combatting “resting” bacteria
Blocking long phosphate molecules could eventually help treat chronic infections in which slow-growing bacteria evade typical antibiotics.
