Researchers engineered Escherichia coli Nissle 1917 bacteria to produce anticancer agent Romidepsin, which was released from the bacteria and effectively targeted cancer cells in mouse models. The study establishes a solid foundation for bacteria-assisted tumor-targeted therapy, paving the way for future advancements in cancer treatment.
A large E. coli outbreak in Calgary daycare centers resulted in 285 children becoming infected, with daily laboratory monitoring and treating dehydration preventing complications and potentially saving lives. The study found that this approach reduced the number of children who developed life-threatening hemolytic uremic syndrome.
Research shows that bacteria harbor resistance genes may respond differently to antibiotics under non-standard conditions. This affects treatment efficacy and contributes to understanding antimicrobial resistance development and spread. Understanding these variations is crucial to combat global public health threats.
Kobe University scientists have engineered bacteria to produce a group of compounds with promising pharmacological activities. The breakthrough uses a rational design strategy to create a platform for industrial production of drug candidates.
Scientists at HZI have developed a new technique to visualize the complex process of bacterial capsule production. They used cryo-electron microscopy to study the Wza-Wzc transport channel, which is responsible for knitting the sugar cloak that protects bacteria from the environment and immune cells.

A new study has found that certain strains of E. coli, commonly found in the human gut, can spread at an alarming rate, comparable to viral outbreaks like swine flu. This breakthrough could inform public health measures and prevent treatment-resistant infection outbreaks.
Researchers at DTU have discovered a way to combat antibiotic-resistant bacteria by nourishing special bifidobacteria that is naturally occurring in the gut. Special lactic acids produced by bifidobacteria play a key role in keeping antibiotic-resistant bacteria at bay.
A Kobe University team has engineered E. coli bacteria to produce the compound pyridinedicarboxylic acid (PDCA) from glucose at unprecedented levels, surpassing previously reported concentrations. The breakthrough enables the clean and efficient synthesis of a biodegradable PET alternative with superior physical properties.
Researchers at Rice University have engineered E. coli to act as living multiplexed sensors, detecting multiple environmental toxins simultaneously by converting biological responses into readable electrical signals. The system can detect combined hazards more efficiently and accurately, with potential applications in biocomputing.
A new study by Cornell University researchers suggests that a combination of efforts, including postharvest techniques and proper cold storage temperatures, can minimize the risk of human health from E. coli outbreaks in romaine lettuce. The study found that contaminated irrigation water is a significant contributor to contamination.
A study by HZI researchers showed that specific strains of E. coli can displace multi-resistant bacteria from the gut, potentially preventing infections and containing their spread. The strains, which were tested in a mouse model, also proved effective against other resistant strains when combined with Klebsiella oxytoca.
Researchers discovered how certain bacteria breathe by generating electricity, using a natural process that pushes electrons into their surroundings. This finding could enable new developments in clean energy and industrial biotechnology.
Researchers at La Trobe University have discovered how enteropathogenic E. coli (EPEC) bacteria use a molecular toxin called EspC to destroy gut cells. This breakthrough could lead to the development of targeted drugs to combat EPEC infections and their devastating consequences, including severe dehydration and death.
Researchers created a bacterial evolutionary map that tracks plasmid gene exchange and identifies barriers to treatment. The study reveals new insights into the co-evolution of plasmids and E. coli strains, paving the way for targeted therapies against antibiotic-resistant infections.
Research finds over 25% of Egyptian milk and dairy products contain E. coli, with one strain causing a Japanese school outbreak; experts hope for effective treatment and prevention methods.
Researchers found that squat toilets release higher concentrations of bacteria than bidet toilets, but ventilation fans significantly lower these levels. Installing efficient exhaust fans can effectively reduce bioaerosol concentrations and exposure risks for the public.
Research led by the University of Michigan reveals that extreme rainfall disproportionately increases E. coli concentrations in recreational waters of communities of color in Texas, particularly those with higher percentages of Black residents in the north and east, and predominantly Latino communities in the south and west.
Researchers at Delft University of Technology discovered that E. coli bacteria can synchronise their movements by trapping individual cells in micro-engineered cavities and coupling them through narrow channels. The team observed coordinated bacterial motion and found that the synchronized movement adhered to universal mathematical rules.
