Researchers discover how phage resistance helps emerge dominant strains of Salmonella

Researchers from the Quadram Institute and the University of East Anglia have discovered how resistance has contributed to the emergence of dominant strains of Salmonella. In addition to antimicrobial resistance, resistance to bacteriophages can give these insects a boost, at least in the short term. With the emergence of antimicrobial resistance, new ways to combat … Read more

Study examines distribution of Klebsiella superbug between humans and the environment

An international team of scientists investigating the transmission of a deadly drug-resistant bacteria that mimics MRSA has found that while the bugs are found in livestock, pets and the wider environment, they are rarely transmitted to humans by this route. The researchers, led by Professor Ed Feil of the Milner Center for Evolution at the … Read more

How gut microbes influence the immune response to SARS-CoV-2

An article published in Critical Assessments in Food Science and Nutrition journal reviews the role of the gut microbiota in shaping the host immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Study: Gut microbiome and antiviral immunity in COVID-19. Image credit: Design_Cells / Shutterstock Background SARS-CoV-2, the causative agent of the 2019 coronavirus … Read more

Well-equipped gut-friendly bacteria hold promise for improving IBD treatments

Like elite firefighters venturing into the wilderness to fight an uncontrolled blaze, probiotic bacteria do a better job of suppressing intestinal inflammation when equipped with the best equipment. A new study by researchers at the University of Wisconsin-Madison shows just how much promise some well-equipped gut-friendly bacteria hold for improving treatments for inflammatory bowel disease … Read more

Private interests in endorsing fluoride-supplemented high-carbohydrate dietary guidelines

Prominent organizations, including the World Health Organization and the United States Department of Agriculture (USDA) have rejected low-carb diets that prevent tooth decay in favor of recommending high-carbohydrate diets that rely on fluoride and food fortification to reduce tooth damage and nutritional deficiencies, a University of Washington said. researcher says. In a recent article published … Read more

Gut colonization by proteobacteria modulates the neurobehavioral response of mice to cocaine

A recent study published in Cell host and microbe revealed that gut colonization by proteobacteria modulates the neurobehavioral response of cocaine in mice. Study: Gut colonization by Proteobacteria alters host metabolism and modulates cocaine neurobehavioral responses. Image Credit: Rost9/Shutterstock Background The human microbiota is composed of bacteria from numerous phyla, such as Firmicutes, Proteobacteria, and … Read more

New delivery system selectively delivers antibiotics to specific targets

Physicists at McMaster University have identified a natural delivery system that can safely transport potent antibiotics throughout the body to selectively attack and kill bacteria by using red blood cells as a vehicle. The platform, described in a new article in the magazine ACS Infectious Diseases, could help address the ongoing antibiotic resistance crisis, the … Read more

These gut bacteria may hold the key to treatment

What Causes Rheumatoid Arthritis? Rheumatoid arthritis is an autoimmune disease, meaning it develops when the body’s immune system begins to attack itself. Proteins called antibodies, which usually help fight viruses and bacteria, start attacking the joints instead. The origin of the antibodies that cause rheumatoid arthritis has been an area of ​​research for many years. … Read more

Groundbreaking gene-editing technique can repair defective T cells in patients with CTLA-4 insufficiency

A flaw in cells that make up an important part of the immune system can be repaired with a breakthrough gene-editing technique, according to new research shown in human cells and mice, led by UCL scientists. Researchers say the study, published in Science Translational Medicinecould lead to new treatments for a rare disease of the … Read more

FebriDX point-of-care immunoassay can quickly determine whether an infection is bacterial or viral

In a recent JAMA network opened research, researchers investigate whether a point-of-care immunoassay called FebriDx can discriminate between bacteria- and virus-induced immune responses during acute respiratory infections based on myxovirus resistance protein A (MxA) and C-reactive protein (CRP) levels of finger sting blood samples. Study: Diagnostic Accuracy of a Bacterial and Viral Biomarker Point-of-Care Test … Read more
