NewsMothers' exposure to microbes protect their newborn babies against infection
A study dives into new depths to explore why only some babies develop severe infection to common bacteria. The research revealed that the babies that became most severely ill from E. coli infections also had markedly lower levels of germ-fighting antibodies transferred from their mothers.

NewsScientists develop shape-shifting scaffold that fights infection and rebuilds bone
Scientists have developed a body-temperature–responsive, 3D-printed shape-memory scaffold coated with a metal–polyphenol network to treat infectious bone defects. It is designed to adapt to irregular bone defects while providing antibacterial activity, immune regulation, and osteogenic support.

NewsDiisobutyl phthalate at environmental concentration promotes conjugative transfer of antibiotic resistance genes
Researchers investigating the ecological safety risks posed by dibutyl phthalate (DBP), in aquatic environments found it significantly increased conjugative transfer frequency in both intragenus (E. coli DH5α to E. coli HB101) and intergenus (E. coli DH5α to B. subtilis WB100N) systems.

NewsElevated E. coli, staph still detected in Potomac river 4 weeks after sewage spill
Nearly a month after a wastewater pipe broke and spewed hundreds of millions of gallons of raw sewage into the Potomac River just north of Washington, D.C., the latest water testing results continue to show high levels of E. coli and S. aureus, including antibiotic-resistant MRSA.

NewsNew insights into how bacteria control DNA synthesis open the door to next generation antimicrobials
A new study combines structural biology, biophysical characterisation and functional assays to delineate how the bacterial transcriptional regulator NrdR’s quaternary structure responds to different nucleotide states and how these changes affect its regulatory activity.

NewsHow bacteria may promote breast cancer
Researchers have discovered how certain pathogenic bacteria in gut and breast tissue can promote breast cancer development and progression by hijacking a key metabolic enzyme known as spermine oxidase (SMOX).

NewsRhododendron-derived drugs now made by bacteria
Bioengineered E. coli bacteria can now produce a group of compounds with anticancer, anti-HIV, antidiabetic and anti-inflammatory activities. The compounds, orsellinic acid-derived meroterpenoids, are produced by Rhododendron species.

NewsBacterial hitchhikers can give their hosts super strength
Molecular hitchhikers living within bacteria can make their hosts extra resistant to medical treatment by corralling them into tightly packed groups. The study introduces a previously unknown avenue through which bacterial infections can become more difficult to treat.

NewsNew AI model improves accuracy of food contamination detection
Researchers have significantly enhanced an artificial intelligence tool used to rapidly detect bacterial contamination in food by eliminating misclassifications of food debris that looks like bacteria. Current methods often require specialized expertise and are time consuming — taking several days to a week.

NewsAntibiotic-resistant bacteria found in many healthy birthing mothers and their newborns
A recent study found gut bacteria resistant to common antibiotics in a sizable percentage of healthy birthing mothers and their newborns. In this study, 38% of bacterial strains resistant to ceftriaxone transmitted from mother to infant were E. coli.
