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.

Study highlights the role of intestinal T cells in modifying psychological stress responses

In experiments with mice and humans, a team led by Johns Hopkins Medicine researchers says it has identified a particular intestinal immune cell that impacts the gut microbiome, which in turn may affect brain functions linked to stress-induced disorders such as depression.

Investigating how gut microbiota affect neuroplasticity and neurodevelopment

In a recent study published in the journal Neuropharmacology, researchers in Pisa, Italy, explored how gut microbiota can influence neuroplasticity.

Review explores trehalose's effects on metabolism and gut microflora

researchers review the bioactive properties of trehalose and its potential pharmaceutical, medical, cosmetic, and food-related applications.

Novel mechanism by which “good” bacteria colonize the gut discovered

The microbes that inhabit the gut are critical for human health, and understanding the factors that encourage the growth of beneficial bacterial species — known as "good" bacteria — in the gut may enable medical interventions that promote gut and overall human health.

What role does dysbiosis play in Parkinson's disease?

The current study, published in the journal Revue Neurologique, is based on the hypothesis that dysbiosis, or unhealthy variations in the gut and oral microbiota, is a key component of PD pathogenesis.

Bacteria require phase separation to thrive in the mammalian gut

The common commensal gut bacterium Bacteroides thetaiotaomicron uses phase separation of the transcription termination factor Rho to colonize and thrive in the mammalian gut, according to a new study in mice.

Study suggests a novel strategy to combat multidrug-resistant S. pneumoniae infections

Pneumococcal disease leads to over three million hospitalizations and hundreds of thousands of deaths annually.

Trial shows encouraging results for neoadjuvant dual immunotherapy and chemotherapy in patients with resectable NSCLC

In a Phase II trial led by researchers from The University of Texas MD Anderson Cancer Center, adding ipilimumab to a neoadjuvant, or pre-surgical, combination of nivolumab plus platinum-based chemotherapy, resulted in a major pathologic response (MPR) in half of all treated patients with early-stage, resectable non-small cell lung cancer (NSCLC).

A high-throughput CAMP assay for the evaluation of the vitamin D-dependent antimicrobial response

A recent developed a novel and high-throughput assay to evaluate cathelicidin antimicrobial peptide.

Purine metabolite xanthine may play a role in Th17 cell differentiation in the gut

The gut is home to a cast of microbes that influence health and disease. Some types of microorganisms are thought to contribute to the development of inflammatory conditions, such as inflammatory bowel disease (IBD), but the exact cascade of events that leads from microbes to immune cells to disease remains mysterious.

The relationship between intestinal microbiome dysbiosis and atherosclerosis

Researchers investigate the impact of intestinal microbiota dysbiosis on atherosclerotic cardiovascular disease incidence.

Using probiotics to treat depression

Researchers discuss whether probiotics could be used as supplementary or primary therapy to manage major depressive disorder.

New biomimetic model helps study wound healing in burn and laceration wounds

Burn wounds are notoriously prone to bacterial infection and typically lead to a larger amount of scar tissue than laceration wounds.

Researchers design a virus-resistant, more useful E. coli bacteria

In a step forward for genetic engineering and synthetic biology, researchers have modified a strain of Escherichia coli bacteria to be immune to natural viral infections while also minimizing the potential for the bacteria or their modified genes to escape into the wild.

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.

Age and sex determine the effects of microbiota on mice's metabolome

The gut handles all ingested foods for further digestion and assimilation. In addition, it harbors a wealth of microbes that produce metabolic byproducts with multiple effects on host physiology. Therefore, changes in the gut microbiome's composition can shift the gut's metabolome as well.
