How Crohn’s disease-associated bacteria tolerate antibiotics

Bacteria associated with Crohn’s disease rely on multiple stress responses to survive, multiply, and tolerate antibiotics within white blood cells called macrophages, according to a study published November 14 in the open-access journal PLOS Pathogens by Olivier Espéli of the College de France and PSL Research University in Paris, France, and colleagues. Crohn’s disease is […]

Salmonella causing bloodstream infections in central Africa resistant to nearly all drugs

The first extensively drug-resistant (XDR) strains of Salmonella typhimurium, a pathogen which is responsible for millions of bloodstream infections per year in sub-Saharan Africa, have been identified in the Democratic Republic of Congo (DRC). Drug-resistance has increased in successive groups of S. typhimurium over time. These new strains are resistant to all but one of […]

Bacteria in pneumonia attack using bleaching agent

Research shows that bacteria use hydrogen peroxide to weaken the immune system and cause pneumonia. This according to a study at Umeå University and Stockholm University, Sweden. Hydrogen peroxide is also known as a bleaching agent that is used to whiten teeth or hair, as a stain remover, as well as for cleaning surfaces and […]

Study finds way to disarm dangerous bacteria

In Australia, more than 10,000 patients a year acquire a serious bacterial infection called Clostridioides difficile, often while in hospital, resulting in the death of up to 300 people per year. The Centers for Disease Control in the United States (US) call C. difficile a major health threat causing half a million infections and 15,000 […]

Precision editing of gut bacteria reduces cancer in mice

UT Southwestern researchers have shown that precision editing of the bacterial populations in the gut reduces inflammation-associated colorectal cancer in mice. The study published this week by the Journal of Experimental Medicine could lay the groundwork for novel cancer prevention strategies for individuals with chronic intestinal inflammation. Inflammatory bowel disease (IBD) affects more than 1.6 […]
