FeaturesThe growing threat of nontuberculous mycobacteria infections
Once overlooked, NTM are now drawing increased attention as their infections pose significant and complex diagnostic challenges. Advances in diagnostic technologies offer the potential to overcome these hurdles to enable precise species-level detection, guide targeted therapy.

NewsHow the plague bacillus became less virulent, prolonging the duration of two major pandemics
Scientists have discovered that the evolution of a gene in the bacterium that causes bubonic plague, Yersinia pestis, may have prolonged the duration of two major pandemics. Modifying the copy number of a specific virulence gene increases the length of infection.

NewsUncovered: A long-lasting history of leprosy in the Americas
A new study challenges the view that leprosy is a disease that was introduced into the Americas during European colonization. A strain of leprosy-causing mycobacterium, Mycobacterium lepromatosis, infected humans in the Americas before European contact.

NewsGut bacteria may hold key to unlocking better cancer treatment
Scientists have discovered a range of microbial ‘biomarkers’ that could help to improve detection and treatment of gastrointestinal diseases (GIDs) such as gastric cancer (GC), colorectal cancer (CRC), and inflammatory bowel disease (IBD).

NewsIntestinal bacteria influence aging of blood vessels
Researchers have shown for the first time that intestinal bacteria and their metabolites can accelerate the ageing of blood vessels and trigger cardiovascular disease.

NewsBiologist examines growth patterns in bacteria to help develop more targeted, effective antibiotics
Among the new investigative projects at the University of Texas at Arlington is one headed by Dr. Cara Boutte, who is studying how certain bacteria grow by examining how they build their cell walls, an effort that could lead to the development of more effective antibiotics.

NewsUsing bacteria to improve microbiota resistance to pathogens
A new study aimed to identify the bacteria involved in the barrier effect shown by microbiota and prove their effectiveness in preventing the proliferation of pathogenic bacteria, with a view to developing a therapeutic strategy.

NewsTwo-step method to prevent biofilm regrowth is a SLAM dunk
A new study reports a novel, two-step method to effectively dismantle bacterial biofilms and prevent regrowth.

NewsStudy discovers DNA switch that controls TB growth – and could help unlock its antibiotic resistance secrets
The bacteria that cause tuberculosis (TB) may have an ‘on-off switch’ that lets them pause and restart growth, according to a new study which helps explain why TB is so hard to treat with antibiotics and could pave the way for better drugs.

NewsDNA test detects three times more lung pathogens than traditional methods
A study on the application of Metagenomic next-generation sequencing (mNGS) found it can achieve early detection of pathogens and accelerate development of targeted anti-infection treatment plans, improving treatment outcomes and patient prognosis.

NewsNew Unilever research uncovers link between skin microbiome and mental wellbeing for the first time
A study shows concentrations of specific beneficial microbes that live on the skin, particularly Cutibacterium, are linked to psychological wellbeing. Higher levels on the face and underarm were associated with lower stress.

NewsBacterial species join forces to boost production in soybean - without disrupting soil microbiome
Combining a bacterial isolate with rhizobia can boost soybean production without disrupting the natural soil microbiome, a new study reveals.

NewsAncient remains reveal how a pathogen began to use lice – not ticks – to infect humans
Researchers have analysed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread through lice rather than ticks, and how it gained and lost genes in the process.

NewsTuberculous meningitis: study shows that metabolism drives mortality
A new study suggests that dysregulated β-oxidation may be an important and potentially modifiable contributor to mortality in tuberculous meningitis.

NewsWhen fungi take your breath: How a mold can unbalance the lungs
New study reveals that infection with Aspergillus fumigatus not only changes the lungs - the intestines and metabolism also play a surprising role.
-
NewsEngineered bacteria can deliver antiviral therapies and vaccines
New research demonstrates how specially engineered bacteria taken orally can operate as a delivery system for antiviral therapies and vaccines.
-
NewsScientists uncover how certain cholera strains are so successful at evading phage attacks
A new study shows that a virulent lineage of cholera acquired multiple distinct bacterial immune systems that have protected it from diverse types of phages. This defense may have contributed to the massive scale of the Latin American epidemic.

NewsResearchers reveal remarkable antimicrobial activity in hydrogen boride nanosheets
Hydrogen boride (HB) nanosheets represent an exciting new frontier in the search for technologies that can combat microbes in everyday settings. Researchers discovered that they exhibit excellent antibacterial, antiviral, and antifungal properties.

NewsSelenium exposure during pregnancy may reduce childhood streptococcal infections
Higher maternal selenium levels during pregnancy were associated with a lower risk of streptococcal infections in children, a new study shows, suggesting a potential protective effect.
