Visiting biosafety level-4 laboratories

Experiments with the most dangerous human viruses, such as Ebola virus and Lassa virus, are carried out in biosafety level 4 (BSL-4) laboratories. Since visiting the Northeast Infectious Diseases Laboratory BSL-4 and releasing the documentary video Threading the NEIDL, I was given the opportunit... Read More

Cell Discovery Could Lead to Strep Throat Vaccine

A new study clarifies how Group A Streptococcus (strep) bacteria resist the human immune system.

The research could eventually lead to the development of a safe vaccine against strep throat, necrotising fasciitis (flesh-eating disease), and rheumatic heart disease.

Previous efforts to deve... Read More

Foodborne bacteria can cause disease in some breeds of chickens after all

Contrary to popular belief, the foodborne pathogen Campylobacter jejuni is not a harmless commensal in chickens but can cause disease in some breeds of poultry according to research. Campylobacter jejuni is the most frequent cause of foodborne bacterial gastroenteritis in the world and the Cente... Read More

Sugar Protects Cells from Bacterial Invasion

No admission for bacteria: Scientists from the University of Freiburg have succeeded in preventing Pseudomonas bacteria from entering host cells with the help of a sugar complex. Dr. Thorsten Eierhoff and junior professor Dr. Winfried Römer from the Institute of Biologie II, both members of the ... Read More

Meet the electric life forms that live on pure energy

Unlike any other life on Earth, these extraordinary bacteria use energy in its purest form – they eat and breathe electrons – and they are everywhere

STICK an electrode in the ground, pump electrons down it, and they will come: living cells that eat electricity. We have known bacteria to surv... Read More

We Are Our Bacteria

We may think of ourselves as just human, but we’re really a mass of microorganisms housed in a human shell. Every person alive is host to about 100 trillion bacterial cells. They outnumber human cells 10 to one and account for 99.9 percent of the unique genes in the body.

Bacterial Respiratory Tract Colonization Prior to Catching the Flu May Protect Against Severe Illness

Many studies have shown that more severe illness and even death are likely to result if you develop a secondary respiratory infection after developing influenza. Now, however, a team of researchers based at The Wistar Institute has determined that if you reverse the order of infection, the bacte... Read More

Ötzi's non-human DNA: Opportunistic pathogen discovered in Iceman tissue biopsy


EURAC and University of Vienna discover an opportunistic pathogen in an Iceman tissue biopsy

Ötzi’s human genome was decoded from a hip bone sample taken from the 5,300 year old mummy. However the tiny sample weighing no more than 0.1 g provides so much more information. A team of scientist... Read More

Implications of finding poliovirus in sewers of Brazil and Israel

Wild poliovirus has been detected in the sewers of Brazil and Israel. Fortunately, no cases of poliomyelitis have been reported in either country. Why is poliovirus present in these countries and what are the implications for the eradication effort?

Wild type poliovirus (e.g. not vaccine-deri... Read More

Evolutionary origins of plant/bacteria symbiosis

The symbiosis between some plant species and nitrogen-fixing nodule bacteria is one of the most relevant cooperative relationships in the world. It shapes our global vegetation and, not least, the global nitrogen and carbon cycle. The foundations for this process were probably laid in just one e... Read More

Ebola outbreak: 25 more deaths confirmed in West Africa

A Possible Solution to Toilet Stink in China

Using public toilets in China can often be a challenging undertaking, particularly for those not practiced in the art of squatting. But researchers in China have come up with a new technology that they say can help eliminate one of the most noxious of problems to plague China’s public lavatories... Read More

Pediatrician Jennifer Halverson will never forget her 36th birthday.

The St. Paul native was volunteering at a maternity clinic in Port-au-Prince, Haiti. She felt great — she went to her job that day and then out to dinner with friends.

But when she got home and went to sleep that night in... Read More

New Gut Bacteria Finding Could Be Key To Diabetes, Antibiotic Crisis

A team of Chinese and Danish researchers has identified 500 new species of gut-residing microorganisms and 800 new bacterial viruses which could attack them. The findings could lead to promising new treatments and possibly circumvent the current crisis of antimicrobial resistance.

Using a tec... Read More

Bacterial switches in the human gut pave way for therapeutic manipulation

The microbial ecosystem in the human gut can switch from one stable state into another, without staying for a long time in between. Key groups of bacteria tend to be either nearly absent, or relatively abundant in any given individual. This discovery highlights fundamental organizing principles ... Read More

The Forgotten Woman Who Made Microbiology Possible

Read about Angelina Fanny Hesse, an unsung heroine of microbiology who helped make the isolation of bacteria possible in this Popular Science blog post by Christina Agapakis:

"In the earliest days of microbiology, scientists were stumped about how to isolate bacteria. That is, until the fami... Read More

Choosing cheese: Research identifies microbial communities in cheese

After studying 137 varieties of cheese collected in 10 different countries, researchers have been able to identify three general types of microbial communities that live on cheese, opening the door to using each as a 'model' community for the study of whether and how various microbes and fungi c...
