Salmonella Could Be Combated

Due to the critical role played by autophagy in pathogen clearance, pathogens have developed diverse strategies to subvert it. Despite previous key findings of bacteria-autophagy interplay, asystems-level insight into selective targeting by the host and autophagy modulation by the pathogens is lacking. Researchers predicted potential interactions between human autophagy proteins and effector proteins from 56…

Bacteria May Travel Thousands Of Miles

Bacteria may travel thousands of miles through the air worldwide instead of hitching rides with people and animals, according to Rutgers and other scientists. Their “air bridge” hypothesis could shed light on how harmful bacteria share antibiotic resistance genes. “Our research suggests that there must be a planet-wide mechanism that ensures the exchange of bacteria…

Bacteria-mimicking Particles: Treat Infectious Diseases

Unique particles modified to mimic bacteria may provide a better means of treating infectious diseases, such as tuberculosis. Assistant Professor Joshua Reineke of the South Dakota State University Department of Pharmaceutical Sciences and his team modified microparticles, known as metal organic frameworks (MOFs), developed by a research group in France. Other researchers have explored MOFs as…

Could The Bacteria In Our Gut Help Treat Cancer?

“The microbiome is a huge part of who we are,” says Dr. Marios Giannakis.”We have more microbes in our bodies than human cells and yet we still don’t fully understand the role they play in health and disease.” The microbiome is a collection of trillions of microorganisms, spanning bacteria, fungi and viruses, that call the…

Bacteria In Urine: Doesn't Always Indicate Infection

Asymptomatic bacteriuria (ASB) is a common finding in many populations, including healthy women and persons with underlying urologic abnormalities. The 2005 guideline from the Infectious Diseases Society of America recommended that ASB should be screened for and treated only in pregnant women or in an individual prior to undergoing invasive urologic procedures. Treatment was not…

New Plant-based Vaccine: Affordable HPV Prevention

Do you change the channel when you see an ad for the Gardasil vaccine? Maybe you are a man and don’t think you are at risk of acquiring cancer from HPV, maybe you aren’t sexually active, or maybe you don’t have the resources to get the vaccine. But research shows that in addition to causing cervical…

Microbes Can Grow On Nitric Oxide

Nitric oxide is a fascinating and versatile molecule; important for all living things as well as our environment. It is highly reactive and toxic; used as a signaling molecule, it depletes the ozone layer in our planet’s atmosphere and it is the precursor of the greenhouse gas nitrous oxide. Nitrogen oxides are also pollutants discharged…

Cholera detection

Sensitivity Of Microbiological Cultures: For Detecting Cholera

Cholera is an infectious disease that causes severe watery diarrhea, which can lead to dehydration and even death if untreated. It is caused by eating food or drinking water contaminated with a bacterium called Vibrio cholerae. Cholera was prevalent in the U.S. in the 1800s, before modern water and sewage treatment systems eliminated its spread by contaminated water. Only about 10…

Slowing Down Antibiotic Resistance: Bacteria 'Trap' Help

Scientists have developed a new and faster test for identifying how single bacteria react to antibiotics, which could help in the fight against antimicrobial resistance. Knowing how drugs impact single bacteria can help clinicians target the right antibiotics more quickly, reducing the need for prolonged treatment that in the long-term contributes to antibiotic resistance. Effective…

Purple Bacteria Can Visualize Tumor Heterogeneity

Cancer presents an ongoing challenge for physicians, particularly in the diagnosis and treatment of the disease. This is, amongst other things, due to tumor heterogeneity. A team of scientists from the Helmholtz Zentrum Muenchen, the Juelich Research Center, the Technical University of Munich and the Heinrich Heine University Duesseldorf has now shown that harmless purple…

Sophistication Of Microbial Warfare

It could be the plot of an espionage-filled, war-time thriller, or the blow-by-blow of sparring judo masters. But instead it’s a true story of molecular warfare between microbes, beginning when a virus latches into a bacterium and injects its DNA, the first step toward infection. Scientists have known for a century that viruses attack and…

The Complexity Of Microbial Communities

“Microbial communities run the world,” says Jo Handelsman, director of the Wisconsin Institute for Discovery at the University of Wisconsin-Madison.”People always laugh when I say that,” she adds. “But it’s true.” Our rich new understanding of microbial communities and their influence on human health or crop productivity has led to the dream of changing these…
