Bacteria Research: Tracing the evolution of a drug-resistant pathogen ♦ Sweet revenge against superbugs ♦ Dairy products boost effectiveness of probiotics

New variant of streptococcal bacteria causing severe infections Scientists have discovered a new variant of streptococcal bacteria that has contributed to a rise in disease cases in the UK over the last 17 years.
Dairy products boost effectiveness of probiotics The success of probiotics for boosting human health may depend partly upon the food, beverage, or other material carrying the probiotics, according to research.
New insights into biofilm formation could lead to better therapies, but mysteries remain Biofilms are tough, opportunistic, highly antibiotic resistant bacterial coatings that form on catheters and on medical devices implanted within the body. Investigators have now shown that a 'messenger molecule' produced by the opportunistic human pathogen, Pseudomonas aeruginosa, encourages bacteria to colonize catheters in the bladders of laboratory mice, where they form biofilms.
Tracing the evolution of a drug-resistant pathogen Researchers are studying a antibiotic-resistant pathogen to learn how to better fight it. They have identified several mechanisms bacteria use to share genes and expand their antibiotic resistance.

Sweet revenge against superbugs A special type of synthetic sugar could be the latest weapon in the fight against superbugs. A team of scientists has discovered a potential new class of antibiotics inspired by sugar molecules produced by bacteria. New antibiotics to which bacteria are unlikely to develop resistance are urgently needed to combat the rise of superbugs -- drug resistant bacteria
