A study of sewage from four Indian cities found many antibiotic resistance genes and similar resistance patterns. The 2025 National Action Plan and experts promote wider wastewater surveillance, but critics warn of weak implementation.

Two research papers report that adding wheat fiber to the diet protects mice from intestinal inflammation. Gut bacteria release polyphenols from the fiber that reduce inflammation, and authors suggest whole-grain foods may lower IBD risk.
Emory University researchers found that a short high-fat diet can let live gut bacteria travel to the brain in mice. The bacteria moved along the vagus nerve; returning to a normal diet reduced this effect and researchers call for more study.
Scientists paired rifampicin with a probe called AAP-SO2 that binds bacterial RNA polymerase at a different site and slows transcription. The pair killed resistant mutants in culture and was especially effective in a rabbit model.
Yale researchers imaged the molecular structure of Vibrio cholerae flagella in living bacteria. The study shows how flagella proteins sit inside a hydrophilic sheath and suggests the sheath helps the bacterium move and infect cells.
