Many respiratory infections, such as influenza or COVID-19 add significant stress to cells and organs, which can lead to acute respiratory distress syndrome (ARDS), which itself can eventually cause death in aged or sensitive individuals.
The supply of a plant-derived anti-cancer drug can finally meet global demand after a team of scientists from Denmark and the U.S. engineered yeast to produce the precursor molecules. Previously, obtaining one gram of the chemotherapy drug required growing and harvesting 500 kilograms of the native plant's leaves.
Beetles of the genus Lagria need a little help from their bacterial friends throughout their immature life stages. But keeping them in the same spot throughout life isn't feasible.
New study reveals that the bacterial communities that live in subarctic caves, which can give rise to products of particular interest to medicine and industry, are more diverse and complex than those that live on the surface soils in same area.
Amoebae receive surprising support in defense against viruses: The bacteria they are infected with prevent them from being destroyed by giant viruses. A research team led by microbiologist Matthias Horn from the Centre for Microbiology and Environmental Systems Science at the University of Vienna have investigated how a virus infection proceeds when the amoebae are simultaneously infected with chlamydia. The research team shows for the first time that intracellular bacteria known as symbionts protect their host against viruses. Amoebae are protists, i.e. single-celled microorganisms with a cell nucleus. Protists play a key role in food webs and ecosystem processes. Consequently, the results of the study suggest that the interaction between symbionts and viruses influence the flow of nutrients in ecosystems. The study is now published in the journal PNAS.
In the normal small intestine, the levels of SFB and Th17 cells are both maintained constant as they counterbalance each other.
Adding to a growing body of research on mental health and the human microbiome, a new study compared the bacteria in the saliva of students with and without recent thoughts of suicide, called suicidal ideation
Your gut microbiome, the community of bacteria living in your digestive system, is not just affected by your diet and environment, but can be influenced by your genes too, say scientists.
A substance produced by gut microorganisms can lead to scarring and blood vessel damage in patients with scleroderma, a new study suggests. Researchers say they will examine whether drugs or food products, like virgin olive oil, can block the formation of the compound in the gut to treat fibrosis.

Scientists at the Department of Energy’s Oak Ridge National Laboratory have created a miniaturized environment to study the ecosystem around poplar tree roots for insights into plant health and soil carbon sequestration.
The latest research and expert commentary on the monkeypox outbreak.
Likely to survive in the oral cavity, bacteria evolved to divide along their longitudinal axis without parting from one another. A research team co-led by environmental cell biologist Silvia Bulgheresi from the University of Vienna and microbial geneticist Frédéric Veyrier from the Institut national de la recherche scientifique (INRS) just published their new insights in Nature Communications. In their work, they de-scribed the division mode of these caterpillar-like bacteria and their evolution from a rod-shaped ancestor. They propose to establish Neisseriaceae oral bacteria as new model organisms that could help pinpoint new antimicrobial targets.
Treating allergic mice with a form of butyrate — which is produced by good gut bacteria — protects against peanut allergy, scientists report today. The treatment might also counteract other food allergies and inflammatory diseases. They will present their results at ACS Fall 2022.
A new analysis of remains from medieval Cambridge shows that local Augustinian friars were almost twice as likely as the city’s general population to be infected by intestinal parasites.
Cedars-Sinai investigators have developed a method to help identify which human gut microbes are most likely to contribute to a slew of inflammatory diseases like obesity, liver disease, inflammatory bowel disease, cancer and some neurological diseases.
RUDN biologists have studied microorganisms that can survive in metalworking fluids. The results will allow “picking up” bacteria and fungi that can process toxic waste fluids into a harmless product.
Could the design of a hospital or a school affect the germs that can spread within it? UNC Charlotte bioinformatics professor Anthony Fodor is part of a team seeking to find out. He is among the group of researchers undertaking an effort to better understand and improve the microbial communities of where people live, work and play.

In the pursuit of accurate diagnoses for illnesses, doctors have traditionally used multiple methods to try to identify the bacterium, virus, fungus or other pathogen responsible for an infection.
The increase in the discovery of Arcobacter in food samples of all types raises public health concerns, as very little is known as yet about the pathogenic potential of Arcobacter species, and the few studies that have been carried out show a large number of host species and transmission routes.
UC San Diego researchers report using native bacteria in mice as the chassis for delivering transgenes capable of inducing persistent and potentially even curative therapeutic changes in the gut and reversing disease pathologies.

The McMaster-Queen’s research team pinpointed the bacterium Klebsiella aerogenes as the key histamine producer by studying germ-free mice colonized with gut microbiota from patients with IBS. They also colonized some mice with gut microbiota from healthy volunteers as a control group. The study found that the bacterium Klebsiella aerogenes converts dietary histidine, an essential amino acid present in animal and plant protein, into histamine, a known mediator of pain.
