New therapeutic strategy can prevent dental decay in children

The combination of a carb-heavy diet and poor oral hygiene can leave children with early childhood caries (ECC), a severe form of dental decay that can have a lasting impact on their oral and overall health.

Study describes IgG antibodies in Crohn's disease specific for human bacterial flagellins

Last year, Charles O. Elson, M.D., demonstrated a potential preventive treatment for Crohn's disease, a form of inflammatory bowel disease. He used a mouse model that included immune-reactive T cells from patients with Crohn's disease in a flagellin peptide-specific immunotherapy.

Cholestenone could be a new antibacterial drug against H. pylori

Helicobacter pylori (H. pylori), a gram-negative pathogen that has infected half of the world's population is a Group I carcinogen according to the WHO. H. pylori resides in the gastric mucosa causing gastritis, ulcers, gastric cancers and malignant lymphoma of the stomach.

Researchers unravel the molecular basis of how Mtb uses and transports an essential sugar

Tuberculosis is a devastating disease that claims over 1.5 million lives each year. The increase in TB cases that are resistant to the current antibiotics means that novel drugs to kill Mycobacterium tuberculosis (Mtb) are urgently needed.

Leaky gut and microbial dysbiosis could contribute to cytokine storm in severely ill COVID-19 cases

The gut is a well-established route of infection and target for viral damage by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent for COVID-19. This is supported by the clinical observation that about half of COVID-19 patients exhibit gastrointestinal (GI) symptoms.

Microbiota-derived molecules do not change the entry or replication of SARS-CoV-2 in intestinal cells

A study conducted at the University of Campinas in the state of São Paulo, Brazil, shows that compounds produced by gut microbiota (bacteria and other microorganisms) during fermentation of insoluble fiber from dietary plant matter do not affect the ability of the novel coronavirus SARS-CoV-2 to enter and replicate in cells lining the intestines.

Study demonstrates the impact of 'reverse antibiotic' on gram-negative bacteria

Scientists from Skoltech and MSU have investigated antibiotic nybomycin that could prove effective against bacteria resistant to other antibiotics. Their research was published in the journal Antimicrobial Agents and Chemotherapy.

Human monoclonal antibodies can act as a substitute for traditional antibiotics

In the course of a new and groundbreaking study, led by Dr, Natalia Freund and the doctoral candidate Avia Waston at the Sackler Medical Faculty, the research group succeeded in isolating monoclonal antibodies, which hindered the growth of tuberculosis germs in laboratory mice. The

Novel method instructs immune cells to help repair damaged tissues in the intestine

A method that instructs immune system cells to help repair damaged tissues in the intestine has been developed by researchers at KU Leuven and Seoul National University.

Study shows how bacteriophage lysis genes could be key to developing new antibiotics

A study from the Center for Phage Technology, part of Texas A&M's College of Agriculture and Life Sciences and Texas A&M AgriLife Research, shows how the "hidden" genes in bacteriophages -- types of viruses that infect and destroy bacteria -- may be key to the development of a new class of antibiotics for human health.

New type of flour improved the glycemic response of people eating white bread

Researchers from the Quadram Institute and King's College London have shown that replacing wheat flour with a new ingredient derived from chickpeas improved the glycemic response of people eating white bread.

Xylitol and grapefruit seed extract shows promise in preventing SARS-CoV-2 infection, study finds

A team of researchers at the Feinberg School of Medicine demonstrated that xylitol and grapefruit seed extract (GSE) could prevent SARS-CoV-2 infection. These can be used as a nasal spray to contain the spread of the coronavirus.

Vibrational motions of spike proteins correlate with infectivity and lethality of coronaviruses

When someone struggles to open a lock with a key that doesn't quite seem to work, sometimes jiggling the key a bit will help.

Promising new antivirals target arboviruses and SARS-CoV-2: Nodosome inhibitors

A new study describes two promising small molecules that inhibit a host cell factor, called nucleotide binding oligomerization domain-containing protein 2 (NOD2), that inhibits the replication and spread of many arboviruses. This could lead to the development of broad-spectrum antivirals. The study's findings have been published on the preprint server bioRxiv*.

Research uncovers key to piercing dangerous bacteria's armor

Bacteria are single-celled organisms that are essential to human health, both in our environment and inside our own bodies. However, certain bacterial species can make us sick.

Engineers use electric fields to manipulate viruses in microfluidic device

The technique uses microfluidics -- the submillimeter control of fluids within a precise, geometric structure. On what is basically a tricked-out microscope slide, chemical engineers from Michigan Technological University have been able to manipulate viruses in a microfluidic device using electric fields.

COVID-19 patients at risk of fatal co-infection during ICU stays

Researchers in the UK have conducted a study showing that a high proportion of patients admitted to intensive care units (ICU) with coronavirus disease 2019 (COVID-19) acquire a secondary bacterial co-infection during their hospital stay.

Scientists discern molecular mechanisms underlying plant parasitism, cross-species grafting

Using the model Orobanchaceae parasitic plant Phtheirospermum japonicum, scientists from Nagoya University and other research institutes from Japan have discerned the molecular mechanisms underlying plant parasitism and cross-species grafting, pinpointing enzyme β-1,4-glucanase (GH9B3) as an important contributor to both phenomena.
