Antibiotics can temporarily upset your stomach, but now it turns out that repeatedly taking them can trigger long-lasting changes in all those good germs that live in your gut, raising questions about lingering ill effects.
Nobody yet knows if that leads to later health problems. But the find... Read More
Researchers who observed hand washing in restrooms in major cities say 85% of adults are washing their hands after using public facilities, a new observational study shows.
The American Society for Microbiology (ASM) and the American Cleaning Institute (ACI) sent observers into restrooms in s... Read More
Using vancomycin before surgery appears to help reduce the risk of methicillin-resistant Staphylococcus aureus (MRSA) infection in patients testing positive for colonization with nasal swabs -- but may not help patients without preoperative colonization, researchers said here.
A retrospective... Read More
Balamuthia mandrillaris is a free-living ameba (a single-celled organism) found in soil and dust. Exposure to Balamuthia is likely to be common because of how widespread it is in the environment. However, very few cases of disease in humans have been found worldwide since Balamuthia was discove... Read More
People who go to countries like India seeking faster, cheaper medical care risk dire consequences to their own health and they also potentially put the general public at risk if they return home with antibiotic-resistant, emerging infections.That was the ominous message from experts last month...

Fidaxomicin is superior to vancomycin in treating recurrences of gastrointestinal Clostridium difficile infection, according to a blinded randomized trial presented here at the 50th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC).
"Over 20 years, vancomycin has been ... Read More
At the first sign of a disease pandemic, public health officials should begin strongly communicating about the extent of the outbreak and the steps that can be taken by the public to avoid infection, according to two mathematical biologists who have modified the most widely used infectious disea...

Spoilage bacteria that can cause red coloration of pickles' skin during fermentation may actually help clean up dyes in textile industry wastewater, according to a U.S. Department of Agriculture (USDA) study.
Some species of Lactobacilli-food-related microorganisms-can cause red coloring when... Read More
Scientists have successfully cloned a human virus offering new hope for the treatment of potentially life-threatening diseases.
Human cytomegalovirus (HCMV) is a major infectious cause of congenital malformations worldwide. The virus is also known to cause life-threatening disease in transpla... Read More
Bacteria and other microorganisms are known for their remarkable ability to become immune to nearly everything thrown at them, and now a new study provides us with some hints of how that's possible.
Short of being cast into the Sun, in Earth's inner core, or in the deepest corners of space, b... Read More
Whirling electron vortices could help materials scientists to map the properties of nanomaterials in new detail. A technique, detailed in the September 16 issue of Nature, could be used in electron microscopes as part of the continuing quest to scale down the size of electronic chips.
Optical... Read More
In a discovery that sheds new light on the history of AIDS, scientists have found evidence that the ancestor to the virus that causes the disease has been in monkeys and apes for at least 32,000 years — not just a few hundred years, as had been previously thought.
That means humans have pres... Read More
Bacteria that are able to survive every modern antibiotic are cropping up in many U.S. hospitals and are spreading outside the USA, public health officials say.
The bugs, reported by hospitals in more than 20 states, typically strike the critically ill and are fatal in 30% to 60% of cases. Is... Read More
Menachem Shoham, PhD, associate professor and researcher in the department of biochemistry at the Case Western Reserve University School of Medicine, has identified new anti-pathogenic drugs that, without killing the bacteria, render Methicillin Resistant Staphylococcus Aureus (MRSA) harmless by...

We now know MicroRNAs (miRNAs) have big positive and negative impact on replication in DNA viruses, but what about RNA viruses like influenza? The authors of a new study just released by mBio went looking for miRNAs made by the flu virus, but they made an unexpected discovery that may provide i... Read More
However, I do believe their incredible numerical advantage grants them something - a certain Soviet despot supposedly said "Quantity has a quality all it's own" - that demands we stay on good terms w/ them. Read More
Bacteria dining on the oily feast in the Gulf of Mexico enjoyed a first course made mainly of gases in the months after the Deepwater Horizon oil spill, according to a study published in Science1 today. This may have primed the microorganisms to digest some of the more complex hydrocarbons in o... Read More
An extended-release formulation of nevirapine (Viramune) -- intended for once-daily dosing -- had similar efficacy in treatment-naïve HIV patients to the twice-a-day version commonly used, a researcher said here.
At the end of 48 weeks of therapy, 81% of patients treated with the extended-rel... Read More
The expansion of bacterial colonies is one of the classic research areas in biology. In a recent study, Ignasi Pagonabarraga, from the UB Department of Fundamental Physics, and researchers from the University of Edinburgh consider a new model that uses two parameters to reproduce the growth patt...

If there's life on Mars, we might smell it before we see it. A chemical involved in bad breath and flatulence in humans could lead us to alien microbes on the Red Planet.
The sulphur-containing molecule methyl mercaptan is naturally produced in significant quantities on Earth only by microbes... Read More
