by Marshall University This scanning electron microscope (SEM) image shows a mouse skin infection caused by Streptococcus pyogenes (pseudocolored purple). The bacterium, known as flesh-eating bacteria, has aggressively invaded the tissue (blue), causing extensive damage and destruction. The image highlights the severity of necrotizing skin infections and the devastating impact of bacterial invasion on host tissues....

Bacteria in Polymers Form Cables that Grow into Living Gels
January 17, 2025 Scientists at Caltech and Princeton University have discovered that bacterial cells growing in a solution of polymers, such as mucus, form long cables that buckle and twist on each other, building a kind of “living Jell-O.” The finding could be particularly important to the study and treatment of diseases such as cystic...
