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.....»»
Backyard chickens risk pathogen spread
Keeping backyard chickens was already on the rise, and the hobby has become even more popular during the COVID-19 pandemic. Now, a University of Georgia researcher cautions that the practice has risks not just for chickens, but for wildlife and peopl.....»»
Visualizing the process of digestion in the oldest known animal-microbe symbiosis
Marine biologists have been able to visualize for the first time how tropical sponges and their symbiotic bacteria work together to consume and recycle organic food. The research led by Meggie Hudspith and Jasper de Goeij from the University of Amste.....»»
The Mantis Shrimp Inspires a New Material—Made by Bacteria
By 3D-printing scaffolds and dipping them in microbe juice, scientists make robust structures that could one day lead to self-growing roads......»»
Gulls: Sentinels of bacteria in the environment
Gulls are one of the main wild birds that act as reservoirs of Campylobacter and Salmonella, two most relevant intestinal antibiotic-resistant bacteria causing gastroenteritis in humans. Therefore, according to an article published in the journal Sci.....»»
Study identifies "Achilles heel" of bacteria linked to Crohn"s disease
The discovery of an 'Achilles heel' in a type of gut bacteria that causes intestinal inflammation in patients with Crohn's disease may lead to more targeted therapies for the difficult to treat disease, according to investigators......»»
Chimp deaths at Sierra Leone sanctuary linked to a bacterium
An international team of researchers has found what they believe to be the pathogen that has been killing chimpanzees at a Sierra Leone sanctuary for approximately 15 years. In their paper published in the journal Nature Communications, the group des.....»»
Pathogen Discovered That Kills Endangered Chimps: Is It a Threat to Humans?
An Ebola outbreak and a few false leads slowed a 15-year search for bacteria that attack the nerves and gut -- Read more on ScientificAmerican.com.....»»
A novel approach to determine how carcinogenic bacteria find their targets
The gram-negative bacteria Helicobacter pylori (H. pylori) colonize the stomachs of the majority of the world's population. Although most people may never experience major complications due to the pathogen, H. pylori infections increase the risk of c.....»»

Bats living in Cambodia in 2010 carried "nearly identical" pathogen to COVID-19 virus, scientists discover
Bats that lived in a Cambodian cave in 2010 carried a pathogen that is "nearly identical" to the virus that causes COVID-19, scientists have discovered......»»
Researchers find inhibitors effective against a coronavirus enzyme
While the first vaccines have been developed against the pathogen SARS-CoV-2, studies are still underway to identify effective drugs for treating coronavirus infections. Scientists in Gießen, Mainz, and Würzburg in Germany involved in a fundamental.....»»
Modern tomatoes can"t get same soil microbe boost as ancient ancestors
Tomato plants are especially vulnerable to foliar diseases that can kill them or impact yield. These problems require a number of pesticides in conventional crops and make organic production especially difficult......»»
Feces and algorithms: Artificial Intelligence to map our intestinal bacteria
Both past and present-day scientists have suspected the intestines of playing a role in various diseases. Present-day studies focus on the intestinal flora's role in physical diseases such as diabetes and overweight, while others seek to establish a.....»»
How one pathogen evades the immune system
An LMU research team led by Nicolai Siegel has uncovered a mechanism that enables the parasite that causes sleeping sickness in humans to escape the attention of the immune system. The finding may also be relevant to other infectious diseases......»»
The odd structure of ORF8: Mapping the coronavirus protein linked to disease severity
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......»»
The puzzle of nonhost resistance: why do pathogens harm some plants but not others?
People have puzzled for years why pathogen Phytophthora infestens causes the devastating late blight disease, source of the Irish Potato famine, on potatoes, but has no effect at all on plants like apple or cucumber. How are apple trees and cucumber.....»»
Study: Bumble bees lacking high-quality habitat have higher pathogen loads
Bumble bees found in low-quality landscapes—characterized by a relative lack of spring flowers and quality nesting habitat—had higher levels of disease pathogens, as did bumble bees in areas with higher numbers of managed honey bee hives, accordi.....»»
Chemical composition of wild potato relative contributes to its resistance to pathogen
Potato is the most consumed vegetable crop worldwide. However, despite its importance, potato production is severely affected by high susceptibility to a wide range of microbial pathogens, such as bacteria from the genus Pectobacterium, which cause v.....»»
Reston ebolavirus spreads efficiently in pigs
Reston ebolavirus (RESTV) should be considered a livestock pathogen with potential to affect other mammals, including people, according to National Institutes of Health scientists. The caution comes from a study published in Proceedings of the Nation.....»»
