Novel mechanism by which bacteria colonize the gut identified

A new mechanism by which “good” bacteria colonize the gut was unraveled by scientists at Yale University. The finding could aid spur the development of new probiotic therapies.

Common commensal gut bacterium uses phase separation of Rho factor 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.

Fomepizole may reduce disease severity in the lungs of mice with bacterial pneumonia

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

Emergence and spread of a deadly fungus among African amphibians

For the past few years, how a virus triggered a global pandemic has dominated conversations. Now, thanks to the TV show "The Last of Us" (about an apocalypse triggered by brain-eating 'shrooms), fungi have infected popular culture.

Influence of molecular component of caffeine on gut health

Certain microbes are considered to play a role in the development of inflammatory disorders such as inflammatory bowel disease (IBD).

Deciphering the mechanisms used by a fungus to increase iron acquisition

The University of Cordoba discovered how the entomopathogenic fungus Metarhiziumbrunneum increases iron acquisition in melon and cucumber.

Study evaluates the risk posed by the fungus Bd to amphibians across the continent of Africa

Mass fungus infections that drive populations worldwide to near-collapse don't just occur in science fiction. Chytridiomycosis, the worst vertebrate disease in recorded history, has already wiped out hundreds of species of amphibians around the world. Due to a large part to this fungal disease, 41% of amphibians are currently threatened with extinction. Only species living in Africa seemed to have been relatively spared from the scourge of chytridiomycosis – at least so far.

Transforming the natural mineral shells of algae into functional perovskites

Perovskites are materials that are increasingly popular for a wide range of applications because of their remarkable electrical, optical, and photonic properties.

Gut microbiome may modulate the efficacy of CAR-T cell cancer immunotherapy

Scientists from German Cancer Research Center (DKFZ), together with colleagues from Germany, Israel, and the USA, have found that the gut microbiome may modulate the efficacy of CAR-T cellular immunotherapy CAR-T cells in patients with B cell lymphomas.

Bile salt hydrolase cocktails may offer a new approach to inhibit C. diff colonization

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 framework to identify possible viral hazards to human health

The majority of what scientists know about viruses in animals comes from the list of nucleotides that constitute their genomic sequence, which, although useful, provides relatively few signals about a virus’ propensity to infect people.

Novel technology easily detects active Mycobacterium tuberculosis 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.

Analyzing the antimicrobial resistance profile of the main agent of urinary tract infections

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. A healthy gut indicates a stronger immune system, improved metabolism, and a healthy brain and heart, among other functions.

Developing new therapies that leverage the host immune system

Yersinia bacteria cause a variety of human and animal diseases, the most notorious being the plague, caused by Yersinia pestis. A relative, Yersinia pseudotuberculosis, causes gastrointestinal illness and is less deadly but naturally infects both mice and humans, making it a useful model for studying its interactions with the immune system.

Understanding the relationship between gut microbiome and CAR T-cell therapy response

Microorganisms live in or on almost every part of the human body and play an important role in the regulation of normal human processes. As a result, changes in the number or type of microorganisms, also known as the microbiome, can contribute to disease and altered responses to therapy, including cancer treatment.

Bacteriophages might hold the key to fighting antibiotic resistance

As conventional antibiotics continue to lose effectiveness against evolving pathogens, scientists are keen to employ the bacteria-killing techniques perfected by bacteriophages, the viruses that infect bacteria.

Antibiotic usage in livestock leaves an impact on soil carbon and climate

Soils are dependable carbon sinks, which is critical for minimizing the consequences of climate change. Grazing by large mammals promotes soil carbon storage in grasslands, but livestock is progressively replacing wild herbivores across the world.

Study shows mothers provide necessary microbes to babies born via cesarean

Can newborns delivered by cesarean surgery lack vital microbes? Recent data suggests that “no” could be the answer. Mothers are able to transmit bacteria to their babies through alternative, compensating channels, according to research published in the journal Cell Host & Microbe on March 8th, 2023.
