How A Person Can Recover From Ebola

At least eight Ebola patients in Guinea have beaten the odds. They have recovered and been sent home. In past outbreaks, the death rate has been as high as 90 percent. In Guinea so far, about 60 percent of the 157 suspected cases have ended in death.

The first seven to 10 days after infection... Read More

Scientists re-define what’s healthy in newest analysis for Human Microbiome Project

University of Michigan microbiologist Pat Schloss, Ph.D., describes latest findings from Human Microbiome Project. Based on their findings in today’s Nature, there is no single healthy microbiome. Rather each person harbors a unique and varied collection of bacteria that’s the result of life his... Read More

Raw Oysters Spike U.S. Rise in Bacterial Infections

Raw oysters, so good with hot sauce, increasingly can carry something even more unsettling to the stomach: A bacteria linked to vomiting, diarrhea and pain.

Infections with vibrio, a saltwater-based bacteria that can pool in shellfish, jumped 75 percent last year from 2006-2008, the U.S. Cent... Read More

Fighting bacteria with weapons from fungi

In order to survive, organisms produce small molecules known as ‘primary metabolites’ which help it to grow, develop and reproduce. Examples include nucleic acid used to make DNA, amino acids to make proteins, and simple sugars. Once the organism is established it will often start to produce ‘se... Read More

Book Review: 'The Amoeba in the Room' by Nicholas P. Money & 'Missing Microbes' by Martin J. Blaser

From the WSJ:

In 2004, the rebel geneticist Craig Venter took a sailing trip to Bermuda and, unable to resist doing a little research on the side, hauled up 50 gallons of the Sargasso Sea and began trawling it for DNA. It looked for all the world like cold, sterile saltwater, but Mr. Venter h... Read More

The day they discovered the AIDS virus

A historical look back at the discovery of the AIDS virus. Margaret Heckler, president Reagan's Health and Human Services Secretary made the announcement to the world. “First, the probable cause of AIDS has been found: a variant of a known human cancer virus. Second, not only has the agent been ... Read More

Former Research Students and Their Success Stories, Part I!

As an educator and researcher at a small liberal arts institution, my success is measured (to me) in watching former students from my classroom and laboratory go on to do great things after graduation. Here, I share some great information about (and by) a former student of mine, Franny Gilman, ... Read More

Some immune cells defend only one organ

Scientists have uncovered a new way the immune system may fight cancers and viral infections. The finding could aid efforts to use immune cells to treat illness. The research, in mice, suggests that some organs have the immunological equivalent of “neighborhood police” – specialized squads of de... Read More

Hide and Seek: Revealing camouflaged bacteria

Bacteria have developed countless strategies to hide themselves in order to evade attack by the immune system. In the body, Salmonella bacteria use macrophages as host cells to ensure their survival and to be able to spread within the body. Their survival strategy is to nestle into a vacuole wit... Read More

Molecule discovered that smuggles toxins from intestinal pathogens into human cells

Prof. Dr. Dr. Klaus Aktories and Dr. Panagiotis Papatheodorou from the Institute of Experimental and Clinical Pharmacology and Toxicology of the University of Freiburg have discovered the receptor responsible for smuggling the toxin of the bacterium Clostridium perfringens into the cell. The Tpe... Read More

Teaching Freshmen about Transformation, Drug Resistance, and Gene Regulation!

In this blog post, I describe how I use the commonly available pGLO plasmid to teach freshman students basic concepts about transformation, receptor recognition, drug resistance mechanisms, and gene regulation. Oh, and fluorescence via GFP! Read More

Virology question of the week: why a segmented viral genome?

This week’s virology question comes from Eric, who writes:

I’m working on an MPH and in one of my classes we are currently studying the influenza virus. I’d forgotten that the genome is in 8 separate parts. Curious, I’ve been searching but can’t find any information as to why that is?

The malaria pathogen’s cellular skeleton under a super-microscope

The tropical disease malaria is caused by the Plasmodium parasite. For its survival and propagation, Plasmodium requires a protein called actin. Scientists of the Helmholtz Centre for Infection Research (HZI) in Germany used high-resolution structural biology methods to investigate the different... Read More

Study demonstrates that antibacterial soaps can reduce risk of foodborne illness

Newly published research shows that the use of antibacterial soaps can reduce the spread of harmful bacteria - that often leads to foodborne illness - more effectively than using non-antibacterial soaps. The research, published in the peer-reviewed Journal of Food Protection, used new laboratory... Read More

Who cheats and who eats? An evolutionary conundrum.

Say what you will about our other vices, human beings did not invent cheating. Microbes have been doing it for billions of years. You see, for microbes, cheating can sometimes be an evolutionary advantage. And this can cause it to get out of hand really quickly.
