How does an intestinal microbe become a pathogen?
The bacterium Escherichia coli is found in the human intestine, and elsewhere. There it is harmless, but in certain conditions it can become a pathogen. It can cause bladder infections or even sepsis. A team of researchers led by RESIST professor Mar.....»»
A Killer Parasite Is Wiping Out Hordes of Ants—in a Good Way
A microsporidian pathogen is annihilating tawny crazy ants, an invasive menace of the highest order......»»
From rare soil microbe, a new antibiotic candidate
Demand for new kinds of antibiotics is surging, as drug-resistant and emerging infections are becoming an increasingly serious global health threat. Researchers are racing to reexamine certain microbes that serve as one of our most successful sources.....»»
Two DNA defense systems behind resilience of 7th cholera pandemic
Cholera is caused by the bacterium Vibrio cholerae, a waterborne pathogen that infects the gut of humans through contaminated water and food. When ingested, V. cholerae colonizes the gut's inner surface, causing a watery diarrhea, that if left untr.....»»
Researchers identify new targets for immunotherapy in colon cancer
Scientists identify a pathway of immune cell inhibition that may provide the basis for novel approaches to immunotherapy of colon cancer. Their results also highlight important roles of the intestinal microbiota in the development of the disease......»»

How the Chagas pathogen changes the intestinal microbiota of predatory bugs
In Central and South America, predatory blood-sucking bugs transmit the causative agent of the widely prevalent Chagas disease. As the disease can induce severe symptoms and to date there is no vaccine against the Trypanosoma parasites, the main appr.....»»
A new model of pathogen transmission in developing urban landscapes
Scientists from the International Livestock Research Institute (ILRI), the University of Liverpool, the University of Edinburgh and elsewhere have traced how diverse strains of a common pathogenic bacteria spread in Nairobi, Kenya, shedding light on.....»»
Microscopic ocean predator with a taste for carbon capture
A single-celled marine microbe capable of photosynthesis and hunting and eating prey may be a secret weapon in the battle against climate change......»»
Exploring ancient tuberculosis transmission chains
Tuberculosis (TB) is the second most common cause of death worldwide by an infectious pathogen (after Covid-19), but many aspects of its long history with humans remain controversial. Researchers at the Max Planck Institute for Evolutionary Anthropol.....»»
Paper made from banana plants stymies potato pest
Wrapping potato seeds in biodegradable paper made from unusable parts of banana plants reduces the infestation and harmful effects of a nasty plant pathogen—a worm called the potato cyst nematode—and sharply increases potato size and yields......»»
Pathogen-repellent wrap shown to shed viruses as well as bacteria
New research by the inventors of a promising pathogen-repellent wrap has confirmed that it sheds not only bacteria, as previously proven, but also viruses, boosting its potential usefulness for interrupting the transmission of infections......»»
Researchers find hybrid metabolism in fermented food microbe
Lactic acid bacteria are essential in creating fermented foods like yogurt, cheese and sauerkraut. Certain strains are also used as probiotics to improve human gut health......»»
Grouping of immune cell receptors could help decode patients" personal history of infection
Novel software for grouping immunological T-cell receptors may enable the identification of shared patterns that could be used to determine if a person has previously been infected or vaccinated against a given pathogen......»»
Sediments a likely culprit in spread of deadly disease on Florida coral reefs, study finds
A new study found that seafloor sediments have the potential to transmit a deadly pathogen to local corals and hypothesizes that sediments have played a role in the persistence of a devastating coral disease outbreak throughout Florida and the Caribb.....»»
Bird Flu Is Back in the US. No One Knows What Comes Next
The fast-moving pathogen, which has already invaded Europe, was found in East Coast ducks. The last outbreak that tore through the US killed 50 million birds......»»
Scientists map geographic patterns of soil microbe communities in Hexi Corridor deserts
A research group led by Li Yuqiang from the Northwest Institute of Eco-Environment and Resources (NIEER) of the Chinese Academy of Sciences recently mapped biogeographic patterns of soil microbe communities in the Hexi Corridor deserts of northern Ch.....»»
New structure prediction model has mapped 500 previously unsolved proteins
Scientists at the University of California, Berkeley, have recently published work that lays the foundation for new ways of thinking about pathogen evolution. "Our research highlights that template-free modeling that uses machine learning is indeed s.....»»
Scientists prove that deadly gene has jumped from a harmless organism to a nasty pathogen
University of South Australia scientists have made a surprising discovery in the origins of an antibiotic-resistant gene previously thought to have been confined to Adelaide......»»
