How Staphylococcus slips around between biological environments
It's an unpleasant fact that most of us are happy to ignore: Our mouths and noses are the natural homes to infectious and antibiotic resistant bacteria......»»
Protecting your pig from diamond skin disease
Everybody wants to find a diamond in the rough, but no one wants their pig to develop diamond skin disease—an infection that can cause pain and discomfort and may lead to death if left untreated......»»
Woman who went on the lam with untreated TB is now cured
The woman realized how serious her infection was once she was in custody. Scanning electron micrograph of Mycobacterium tuberculosis bacteria, which cause TB. (credit: National Institute of Allergy and Infectious Diseases).....»»
Blue light could kill at least 99% of bacteria linked to dog ear infections, new research shows
New research from the University of Nottingham and University of Birmingham has highlighted that blue light has the ability to kill antibiotic-resistant strains of bacteria isolated from ear infections in dogs......»»
Research team develops new antimalarial agent for combating drug-resistant parasites
Malaria remains a serious health issue globally, especially in Africa. The disease is caused by protozoan parasites in the Plasmodium genus. In 2021, there were 247 million cases of malaria and 619,000 deaths reported worldwide......»»
Stress granules found to play an unsuspected role in blood vessel formation
The behavior of the cells that make up our blood vessels is crucial to our well-being. Conditions such as inflammation, oxygen deprivation and viral infection can stress these cells and disrupt the formation of new, often pathological, blood vessels......»»
"Diagnose, treat and prevent:" Scientists develop test and vaccine for common veterinary infection
Eight years after the market release of VANGUARD crLyme, a first-of-its-kind vaccine designed to prevent Lyme disease in dogs, the Marconi laboratory in the Department of Microbiology and Immunology of the Virginia Commonwealth University School of M.....»»
"It"s unbearable": heat waves scorch southern and eastern Europe
Unrelenting heat is blanketing swathes of southern and eastern Europe, with dozens of cities on red alert as scorching temperatures fuel wildfires, strain power grids, and make daily life unbearable......»»
Study shows small animals use "stolen" genes from bacteria to protect against infection
Certain small, freshwater animals protect themselves from infections using antibiotic recipes "stolen" from bacteria, according to new research by a team from the University of Oxford, the University of Stirling and the Marine Biological Laboratory (.....»»
Advanced nanofibrous membranes can tackle diabetic wounds with precision
Diabetic wounds are notoriously challenging to treat, due to prolonged inflammation and a high risk of infection. Traditional treatments generally offer only passive protection and fail to dynamically interact with the wound environment......»»
E. coli variant may cause antimicrobial resistance in dogs, humans
Researchers studying antimicrobial-resistant E. coli—the leading cause of human death due to antimicrobial resistance worldwide—have identified a mechanism in dogs that may render multiple antibiotic classes ineffective......»»
Interdisciplinary approach provides new insights into molecular mechanisms of cholera infection
Cholera infections caused by Vibrio cholerae bacteria can be life-threatening and the trigger is the cholera toxin produced by the bacteria. It binds to the surface of intestinal cells—more precisely, to certain "sugar lipids" (GM1 gangliosides, GM.....»»
Third betas of iOS 18, iPadOS 18 & macOS Sequoia re-issued ahead of public betas
Apple unexpectedly re-released the third builds for some of its fall operating system releases, including iOS 18, iPadOS 18, and macOS Sequoia.Developers can start to try out Apple's new betas. While Apple regularly releases updates to its betas as n.....»»
A comprehensive derivative synthesis method for development of new antimicrobial drugs
Efforts to combat the increasing threat of drug-resistant bacteria are being assisted by a new approach for streamlining the search for antimicrobial drug candidates, pioneered by researchers at Hokkaido University, led by Assistant Professor Kazuki.....»»
Advanced imaging reveals how a parasitic "kiss" alters cell metabolism
Toxoplasma gondii is a parasite responsible for toxoplasmosis, a lifelong chronic infection prevalent in about 30% of the human population. It poses little harm to healthy individuals, but can result in severe consequences for immunocompromised peopl.....»»
A genome-wide screen in live hosts reveals new secrets of parasite infection
Apicomplexan parasites are a common cause of disease, infecting hundreds of millions of people each year. They are responsible for spreading malaria; cryptosporidiosis—a severe childhood diarrheal disease; and toxoplasmosis—a disease that endange.....»»
Intracellular mechanisms shown to promote spread of deadly bacterial infection
Northwestern Medicine investigators have discovered novel protein mechanisms that promote the rapid spread of Vibrio vulnificus, a rare but lethal bacteria that can cause vibriosis and sepsis, according to findings published in the Proceedings of the.....»»
Features of H5N1 influenza viruses in dairy cows may facilitate infection, transmission in mammals
A series of experiments with highly pathogenic H5N1 avian influenza (HPAI H5N1) viruses circulating in infected U.S. dairy cattle found that viruses derived from lactating dairy cattle induced severe disease in mice and ferrets when administered via.....»»
Low-cost depth imaging sensors achieve 97% accuracy in rapid plant disease detection
A research team has investigated low-cost depth imaging sensors with the objective of automating plant pathology tests. The team achieved 97% accuracy in distinguishing between resistant and susceptible plants based on cotyledon loss. This method ope.....»»
AI able to identify drug-resistant typhoid-like infection from microscopy images in matter of hours
