Gene-cutting system may play second role as a genetic dimmer switch

In a series of experiments with laboratory-cultured bacteria, Johns Hopkins scientists have found evidence that there is a second role for the widely used gene-cutting system CRISPR-Cas9 -- as a genetic dimmer switch for CRISPR-Cas9 genes.

Are antibiotic regimens for critical COVID-19 patients with bacterial superinfection unnecessarily high?

A new study by researchers at Northwestern University Feinberg School of Medicine, USA, shows that antibiotic regimens for critically ill COVID-19 patients with bacterial superinfections may be promoting an unnecessarily high.

Viral genome sequencing of wastewater can be useful for tracking new SARS-CoV-2 variants

Viral genome sequencing of wastewater can detect new SARS-CoV-2 variants before they are detected by local clinical sequencing, according to a new study reported in mBio, an open-access journal of the American Society for Microbiology.

Inflammation may contribute to the persistence of C. diff infection, shows study

A new study from North Carolina State University shows that the inflammation caused by Clostridioides difficile (C. diff) infection gives the pathogen a two-fold advantage: by both creating an inhospitable environment for competing bacteria and providing nutrients that enable C. diff to thrive.

Novel organoid models illuminate path to cervical cancers

How do tumors develop in the cervix? Many new details are now known about this question. This is also thanks to Dr. Cindrilla Chumduri from the Biocentre at the University of Würzburg.

Research uncovers strategy to revert antibiotic-resistance in dangerous superbugs

A major risk of being hospitalized is catching a bacterial infection. Hospitals, especially areas including intensive care units and surgical wards, are teeming with bacteria, some of which are resistant to antibiotics - they are infamously known as ‘superbugs’.

Newly-identified nutrient helps the gut recall prior infections and kill invading bacteria

Scientists studying the body's natural defenses against bacterial infection have identified a nutrient--taurine--that helps the gut recall prior infections and kill invading bacteria, such as Klebsiella pneumoniae (Kpn).

Can cloth masks protect healthcare professionals from SARS-CoV-2?

Given the global scarcity of surgical masks, a recent review study examines this issue - dealing with the potential use of cloth masks in healthcare scenarios.

New DNA test quickly identifies secondary infections in COVID-19 patients

Researchers have developed a DNA test to quickly identify secondary infections in COVID-19 patients, who have double the risk of developing pneumonia while on ventilation than non-COVID-19 patients.

Study may lead to novel synthetic drugs to combat bacterial infections

Researchers at the Technion – Israel Institute of Technology and EMBL Hamburg have discovered remarkable molecular properties of an antimicrobial peptide from the skin of the Australian toadlet. The discovery could inspire the development of novel synthetic drugs to combat bacterial infections.

Scientists make new discovery in the quest for novel antibiotics

Scientists who highlighted the bug-busting properties of bacteria in Northern Irish soil have made another exciting discovery in the quest to discover new antibiotics.

New method uses artificial intelligence to map intestinal bacteria using feces

The intestines and their bacteria are sometimes called our ’second brain’, but studying these bacteria in their natural environment is difficult. Now researchers from the University of Copenhagen have developed a method that uses artificial intelligence to map intestinal bacteria using feces.

Certain oral pathogens are more prevalent in esophageal cancer patients

Researchers led by Tokyo Medical and Dental University (TMDU) find that certain oral pathogens are more prevalent in esophageal cancer patients, and could be used as a novel diagnostic tool.

Researchers develop a tiny, yet effective method for preventing premature birth

In a study in mice and human cells, Johns Hopkins Medicine researchers say that they have developed a tiny, yet effective method for preventing premature birth.

Study summarizes effectiveness of cloth masks in protecting clinicians from COVID-19

A rapid, evidence-based review summarizes the effectiveness of cloth masks in protecting health care clinicians from respiratory viral infections, such as COVID-19. Nine studies were included in the review, and all but one were conducted prior to the COVID-19 pandemic.

Scientists identify bacteria-based approach against cancer

The body's immune system is the first line of defense against infections like bacteria, viruses or cancers. Some cancers, however, have developed the art of molecular deception to avoid destruction by the body's immune system.

Researchers develop novel antibody fragments against SARS coronavirus-2

An international research team led by the University of Bonn (Germany) has identified and further developed novel antibody fragments against the SARS coronavirus-2. These "nanobodies" are much smaller than the classic antibodies used to treat US President Donald Trump, for example.

Biologists reveal unusual structure of coronavirus protein linked to immune evasion

A team of HIV researchers, cellular biologists, and biophysicists who banded together to support COVID-19 science determined the atomic structure of a coronavirus protein thought to help the pathogen evade and dampen response from human immune cells.
