NewsStudy validates DenovAI’s platform for programmable de novo-designed protein therapeutics
Researchers introduce a new class of experimentally validated AI-driven protein design tools that have the potential to accelerate drug development.

NewsImmune tolerance to gut microbes is initiated by a key bacterial sensor
A study has found that the body’s immune “tolerance” to gut microbes depends on an ancient bacterial-sensing protein called STING—normally considered a trigger for inflammation.
-
NewsExcessive use of disinfectants in intensive care patients may increase the risk of antibiotic-resistant infections
An international study has, for the first time, revealed a strong and direct link between the rise of antibiotic-resistant bacteria and universal disinfection procedures applied to patients in intensive care units.
-
NewsGut microbes may help in recognizing and treating pancreatic cancer
A new international cooperation study indicates that in the future pancreatic cancer may be detected at an early stage with the help of gut microbes. Gut microbes may also offer solutions for therapy development.

NewsEvolutionary model for antibiotic resistance reveals dose timing critical to care
The study that uses a “fitness seascape” to incorporate a patient’s dosage schedule into models that predict whether an infection will develop antibiotic resistance has found that inconsistent timing and missing early doses can lead to treatment failure.

NewsMicrobiome stability shapes how corals withstand extreme heat
A new study reveals why some corals resist bleaching while others don’t: the answer lies in a complex partnership between corals and their microbial allies, shaped by the history of the waters they inhabit.

NewsGlobal action urgently needed to tackle antimicrobial resistance, experts warn
Scientists have called for urgent changes to the way new antibiotics are developed to address the growing problem of antimicrobial resistance (AMR). They outline the scientific, economic, and regulatory barriers that are slowing progress.
-
NewsScientists develop a treatment platform to disable the ‘biofilm’ shield of superbugs
Researchers have developed a platform that utilizes microbubbles to deliver gene-targeted nanoparticles capable of breaking down MRSA biofilms, offering an innovative solution for treating infections resistant to conventional antibiotics.

NewsFusobacterium nucleatum in colorectal cancer: Ally mechanism and targeted therapy strategies
A recent review systematically outlines the pathogenic mechanisms of Fusobacterium nucleatum in colorectal cancer and summarizes both current and emerging strategies for its therapeutic targeting.
-
NewsGeneXpert MTB/RIF technology can distinguish non-tuberculous mycobacterial infection
Xpert Mycobacterium tuberculosis/rifampicin (Xpert MTB/RIF) in alveolar lavage fluid can not only detect rifampicin resistance but also distinguish pulmonary tuberculosis (TB) from non-tuberculosis mycobacterial (NTM) pulmonary disease.

NewsEpidemiological trends and serological profiles of respiratory pathogens in Guangzhou
A new study analyzing the epidemiological trends of multiple respiratory pathogens in Guangzhou, China, from 2013 to 2023, indicates the need for age- and gender-specific approaches to infection prevention and management.

NewsProbiotic breakthrough: Bifidobacterium animalis subsp. Lactis A6 shows promise in alleviating comorbid constipation and depression
A new study clarifies how gut microbes influence mental health and offers a safe, targeted probiotic therapy, Bifidobacterium animalis subsp. Lactis A6 (BBA6), for comorbid constipation and depression.
-
NewsWhen bacteria get hungry, they kill – and eat – their neighbors
Scientists have discovered a gruesome microbial survival strategy: when food is scarce, some bacteria kill and consume their neighbors. The researchers show that under nutrient-limited conditions, bacteria use a specialized weapon — the Type VI Secretion System (T6SS) — to attack, kill, and slowly absorb nutrients from other bacterial cells.

NewsAn oral cholera vaccination campaign aims to reach more than 2.6 million people in Sudan’s Khartoum State
A 10-day reactive oral cholera vaccination campaign, launched on 10 June in 5 localities in Sudan’s Khartoum State, aims to protect more than 2.6 million people aged 1 year and above from cholera infection, interrupt transmission and help contain the cholera outbreak.

NewsA combination of exercise and omega-3 reduces the severity of tooth root infections
Rats that exercised and took fatty acid supplements responded better to bacteria and the inflammatory process of apical periodontitis, which can occur when caries reach the root canal and cause an infection.
-
NewsNew research reveals how bacteria export the building blocks of biofilms
Chemists examined how the polysaccharide “Pel” – a central component of many biofilms – is exported out of the cell by the pathogen P. aeruginosa and describe the structure of the so-called PelBC export complex, which represents the last station in the cell before “Pel” is released.

NewsCultured mini-organs reveal the weapons of aggressive Shigella bacteria
Thanks to lab-grown miniature intestines, researchers have successfully mapped how aggressive Shigella bacteria infect the human gut. The study opens the door to using cultured human mini-organs to investigate a wide range of other serious infections.
-
NewsGreen light activates this antibiotic only where it’s needed
To make a more efficient antibiotic treatment, researchers have modified penicillin so that it’s activated only by green light. In early tests, the approach precisely controlled bacterial growth and improved survival outcomes for infected insects.
-
NewsGifts from the sea: Molecules derived from coral may help fight harmful bacteria
Pus, strep throat, and even tuberculosis—most infectious diseases are characterized by a cluster of pathogenic bacteria that can be stubborn and resistant to antibiotics. Researchers have found another method to combat these bacteria using naturally sourced molecules found in corals.

NewsA repurposed FDA-approved drug shows promise in killing antibiotic resistant bacteria
A study of Acinetobacter baumannii employed an entirely new strategy to identify weaknesses specific to resistant bacteria and then target these weaknesses with an alternate drug. They found that fendiline kills the bacterium by targeting the essential lipoprotein trafficking pathway, which is weakened in antibiotic resistant bacteria.
