Bacteria can communicate through a system known as quorum sensing, where, for example the production of toxin in some species is not initiated until a minimum threshold of bacterial cells are present. This allows them to coordinate and therefore strengthen their actions to overcome selective pre... Read More
With drug-resistant bacteria on the rise, scientists believe the nose is engaging in "microbial warfare". Scientists in Germany have identified that Staphylococcus lugdunensis, found in the nose, excretes a compound they named lugdunin. This compound prevents S. aureus from growing. S. aureus ca...

Two studies, in the journal Cell, found a mutation increased the virus' ability to infect human cells fourfold.
Scientists have argued the mutation may have been "pivotal" in the outbreak becoming the largest in recorded history.
There were 28,616 Ebola cases in Guinea, Liberia and Sierra ... Read More
Misdiagnosis can lead to severe consequences for patients, and is a serious clinical issue. The newly emerging Candida auris requires higher doses of antifungal medications to treat an infection than does C. albicans, highlighting the importance of proper diagnosis. Thus far, the most accurate d... Read More
Fine pore diffusers are devices that pump air into wastewater in order to stimulate biodegradation of organic matter. Aeration of wastewater incur a large maintenance cost due to the buildup of biofilm, which is one of the biggest costs to the operation of sewage treatment plants. The biofilms ... Read More
Just like you and me, bacteria have ‘favorite’ foods – though in the case of bacteria, 'favorite' translates to those which are energetically favorable or most accessible. Different bacteria have different preferences, based on their environments and the neighboring microbes that compete for or ... Read More
Many years ago, Homo sapiens mated with Neanderthals. Today a small percentage of our genome remains Neanderthal, and in a study discussed on this episode of the science show This Week in Evolution, we show that some important genes of our innate immune response - the early response against path...

The anaerobic, Gram-positive Clostridium difficile is a big problem. It causes rampant diarrhea and tissue necrosis, with more than 150,000 annual cases in the United States alone. Many of the disease manifestations of C. difficile are mediated by two exotoxins that C. difficile produces: TcdA a... Read More
Cold viruses cause us irritation by penetrating into our cells and transporting their RNA into the cytoplasma of the infected cells. This is the only way they can multiply. The details of how the transfer of the RNA from within the virus occurs are difficult to study. However, a new method has b... Read More
Chemosynthetic symbionts are bacteria living inside or on the surface of animals, supplying their host with food that would otherwise be unavailable. It has long been known that these bacteria fix carbon and convert it into organic forms. Microbiologist Jillian Petersen and colleagues from the U... Read More
Polysorbate, a safe additive found in everything from ice cream to cosmetics, has been proven to slow the toxic effects of E. coli poisoning.
Had this discovery been known before the deadly 2011 E. coli outbreak in Germany, doctors may have had one more tool to save some of victims.
The fi... Read More
Washington, DC – July 12, 2016 – Ebola and Marburg filovirus disease outbreaks have typically occurred as isolated events, confined to central Africa. However, the recent Ebola epidemic spread to several African countries, and caused 11,000 deaths. That epidemic underscored the need to develop v... Read More
At the Rocky Mountain Laboratory in Hamilton, Montana, Vincent speaks with Vincent Munster about the work of his laboratory on MERS-coronavirus and Ebolaviruses.

Klebsiella pneumoniae bacteria exposed to chlorhexidine-containing disinfectants can become resistant to colistin, a last resort antibiotic often used against multidrug resistant pathogens. This is the first study to link exposure to chlorhexidine with resistance to colistin in this clinically i... Read More
A new tool by Japan-based researchers predicts the risk of Zika virus importation and local transmission for 189 countries. Read More
Viruses may be stealthy invaders, but a study at the Weizmann Institute of Science reveals a new, chatty side of some: For the first time, viruses have been found communicating with one another. This communication – short “posts” left for kin and descendants – helps the viruses reading them to d... Read More
Hospital rooms, not just the patients in them, can spread germs through contact with health care personnel, a Duke Health study reports.
“This study is a good wake-up call that health care personnel need to concentrate on the idea that the health care environment can be contaminated,” said De... Read More
A team from the Vetmeduni Vienna and the University of Natural Resources and Life Sciences, Vienna succeeded for the first time in extracting the rare compound cPM from a filamentous fungus, applying a special method. Using this substance leads to increased susceptibility of a resistant pathogen... Read More
In one of the most recent studies involving the microbiiome, researchers from the Mayo Clinic have identified significant differences in the breast bacteria of women with and without breast cancer.
The paper, published in the journal Scientific Reports, reveals that inside the breast is a com... Read More
