Novel subset of memory B cells predicts long-lived antibody responses to influenza vaccination

Memory B cells play a critical role to provide long-term immunity after a vaccination or infection. In a study published in the journal Immunity, researchers describe a distinct and novel subset of memory B cells that predict long-lived antibody responses to influenza vaccination in humans.

Low-cost, universal oral COVID-19 vaccine prevents severe respiratory illness in hamsters

A UCLA-led team has developed an inexpensive, universal oral COVID-19 vaccine that prevented severe respiratory illness and weight loss when tested in hamsters, which are naturally susceptible to SARS-CoV-2.

Co-infection with MRSA ‘superbug’ could make COVID-19 outcomes even more deadly

Global data shows nearly 10 per cent of severe COVID-19 cases involve a secondary bacterial co-infection – with Staphylococcus aureus, also known as Staph A., being the most common organism responsible for co-existing infections with SARS-CoV-2.

Vaginal sex can shape the composition of urethral microbiome in healthy men

Contrary to common beliefs, your urine is not germ free. In fact, a new study shows that the urethra of healthy men is teeming with microbial life and that a specific activity - vaginal sex - can shape its composition.

Avanced genome editing technology could be used as a one-time treatment for CD3 delta SCID

A new UCLA-led study suggests that advanced genome editing technology could be used as a one-time treatment for the rare and deadly genetic disease CD3 delta severe combined immunodeficiency.

SARS-CoV-2 infection damages the CD8+ T cell response to vaccination

The magnitude and quality of a key immune cell's response to vaccination with two doses of the Pfizer-BioNTech COVID-19 vaccine were considerably lower in people with prior SARS-CoV-2 infection compared to people without prior infection, a study has found.

New SARS-CoV-2 Omicron XBB.1.5 variant has high transmissibility and infectivity, study finds

COVID-19 has caused significant global panic after its rapid emergence more than 3 years ago. Although we now have highly effective vaccines against the SARS-CoV-2 virus, which causes COVID-19, scientists continue to study emerging SARS-CoV-2 variants in order to safeguard public health and devise global preventive strategies against emerging variants.

Usefulness of dried blood spot samples for monitoring HCV infection in people who inject drugs

A study with people who inject drugs evaluated a minimally invasive test based on dried blood spots (DBS) for the monitoring of hepatitis C virus (HCV) infection.

Decreased viral infection severity in females may be due to extra copy of X chromosome-linked gene

It has long been known that viral infections can be more severe in males than females, but the question as to why has remained a mystery – until possibly now.

Real-world data on the effectiveness of Sotrovimab as a prophylactic against COVID-19

In a recent study posted in the medRxiv* preprint server, scientists assessed the efficacy of sotrovimab for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) treatment.

Research identifies western diet-induced microbial and metabolic contributors to liver disease

New research from the University of Missouri School of Medicine has established a link between western diets high in fat and sugar and the development of non-alcoholic fatty liver disease, the leading cause of chronic liver disease.

Host immune system forms small lesions in the intestines in response to bacterial infection

Yersinia bacteria cause a variety of human and animal diseases, the most notorious being the plague, caused by Yersinia pestis.

Wayne State team discovers a simple technology to detect active TB infection antibodies

A team of faculty from Wayne State University has discovered new technology that will quickly and easily detect active Mycobacterium tuberculosis (TB) infection antibodies.

The right combination of bile salt hydrolases may offer a new approach to treat C. diff

Not all probiotics are created equal. In a new study, researchers found that certain enzymes within a class known as bile salt hydrolases (BSHs) can restrict Clostridioides difficile (C. diff.) colonization by both altering existing bile acids and by creating a new class of bile acids within the gut's microbial environment.

New study focuses on genetic diversity of E. coli bacteria in hospitalized patients

The human intestine is an environment inhabited by many bacteria and other microorganisms collectively known as the gut microbiome, gut microbiota or intestinal flora. In most people, it contributes to wellness.
