Regular dental visits may help prevent pneumonia, study shows

That twice-yearly trip to the dentist could do more than keep teeth and gums healthy: It may decrease the risk of pneumonia by reducing bacteria in the mouth, suggests research being presented at IDWeek 2016™.

Bacteria that commonly cause pneumonia include streptococcus, haemophilus, staphylo... Read More

New tools to detect new virus

In fall 2015, a new human hepegivirus (HHpgV-1) was identified by using a novel, high throughput sequencing technique. Concerns were raised that this virus was found in blood to be used for transfusions, potentially passing on the infection. But without tools to test for its presence, there was ... Read More

Vials of Zika virus

Like many other virologists we have also begun to work on Zika virus, to apply our expertise and knowledge to this emerging pathogen. Here is a photo of some of the vials of Zika virus that we have recently obtained. Shown are the MR766 and DAK AR 41542 strains and plasma from a Zika virus infec... Read More

Parasites help brine shrimp cope with arsenic habitat contamination

Artemia (the scientific name of the small crustacean that is also commonly known as 'sea monkey') is famous for being able to live in extreme environments and has become a model organism used to test the toxicity of chemicals in water. In addition, Artemia can produce dormant eggs, known as cyst... Read More

An Earth Day Shout-out to Microbes

So another Earth Day has come and gone. How did you spend yours? If you spent the entire day asleep, you used about half a kilogram of oxygen. Since I assume that you are alive and kicking, you probably consumed more oxygen than that. If you went about your normal business during the day, you pr... Read More

Small and extremely resilient—the secrets of black fungi

Highly resistant to stresses, black fungi are real champions among microorganisms. With the support of the Austrian Science Fund FWF, a research team in Vienna discovered that the fungi owe their qualities to hitherto unknown proteins and special processes at cellular level.

They are true sur... Read More

Should You Map Your Microbiome?

Biologists are beginning to understand how the trillions of microbes in and on our bodies shape our health. But differences between any two people’s microbial populations are enormous. Most people share around 99 percent of their DNA with the person next to them, but they have a significantly sm... Read More

Comammox Nitrospira is the dominant bacterium in a drinking water production system

For the last century, nitrification was assumed to be a two-step process executed by two different functional groups, ammonia oxidizing prokaryotes and nitrite oxidizing bacteria. Recently, it was discovered the capability of a single microorganism (belonging to the Nitrospira genus) to carry ou... Read More

Does the hologenome address the whole picture?

How do we define the genetic makeup of an individual? Is it the genetic material found in each cell of that individual (that’s not entirely accurate; mutations and recombinatorial differences can lead to multiple genomes in one individual). And what about the genes carried by our microbiome? The... Read More

Smart Microscope Adapts to Changes in Live Specimens

Recent advances in imaging technology have provided unprecedented views of biological events as they unfold in living organisms. Researchers routinely create movies of processes such as cells dividing and differentiating into the neurons, muscle, and skin in a Petri dish or in tiny embryos, such... Read More

We Know You Want To, but You Really Shouldn't Be Kissing Your Pet on the Mouth

If you live with pets, you know where their tongue has been, yet you let them kiss and lick you all they want without even thinking twice about it. I've heard people say that a dog's mouth is very clean, and that their saliva, delivered by licking, can help heal wounds, but is that really true?

Majority of the E.coli strains are harmless, however certain strains are known to cause serious medical complications.The rising number of supportive initiatives from government... Read More

How lack of oxygen makes bacteria cause acne and how to stop it

It’s like Jekyll and Hyde. One moment bacteria on the skin are harmless, the next they are causing a full-on spotty break out. Now researchers have discovered exactly why this happens – a breakthrough that could yield new acne treatments, possibly in two years.
