Multiple governments and non-governmental organizations have called on health-care personnel the world over to help control West Africa's Ebola outbreak; these include Médecins Sans Frontières (MSF), the World Health Organization (WHO) and United Nations children's charity UNICEF. But the demand... Read More
New research shows how disruption of human biological clock can have negative impact on human intestinal micobiome and in turn lead to metabolic dysfunctions such as weight gain and diabetes. Read More
When Dr. Ian Crozier arrived in West Africa this past summer, he was stepping into the epicenter of the Ebola hot zone. The American doctor was working in the Ebola ward of a large, public hospital in Sierra Leone's dusty city of Kenema.
The trip nearly cost him his life. First came a fever, ... Read More
As part of the Wellcome Trust Strategic Award for Medical Mycology and Fungal Immunology (WTSA MMFI), ten international students are awarded scholarships to complete a Masters of Research (MRes) at the University of Aberdeen, followed by a three-year PhD at any UK institution with expertise in t...

Seth Mnookin, an assistant professor of science writing and associate director of MIT's Graduate Program in Science Writing, is the author of "The Panic Virus: The True Story Behind the Vaccine-Autism Controversy", an acclaimed book that examines how inaccurate scientific reports linking vaccine...

Microbes: They're everywhere, including inside our bodies. But are they really necessary? Not to life, scientists argue in a new paper — but certainly to life as we know it.
For starters, microbiologists Jack Gilbert and Josh Neufeld had to put aside the internal cell structures that were pro... Read More
Nasal drops of harmless bacteria can inhibit a related bug that sometimes causes meningococcal disease, according to new findings published online in Clinical Infectious Diseases. The study--conducted among college students, a group at higher risk for this often serious illness--suggests a new a... Read More
Salt and acid-tolerant bacteria with the potential to be used in mining processing have been uncovered in the Wheatbelt.
The bugs were found during a "bio-prospecting" survey near Merredin and are likely to become more important in WA in coming decades as high-grade ore runs out.
CSIRO envir... Read More
Look what the cat dragged in! The parasite Toxoplasma gondii, a common protozoan transmitted by cats, can effect mammalian brain cells in strange ways. In rodents, the parasite has been shown to inhibit fear and actually attract them to the smell of cat urine. Humans can be infected through c... Read More
While an Ebola epidemic has been raging in West Africa since March 2014, an outbreak of this haemorrhagic fever occurred in the Democratic Republic of the Congo (DRC) in August, leaving fears over the virus' spread to Central Africa. A study by the IRD, the Institut Pasteur, the CNRS, the CIRMF... Read More
Bacteria that can swim propel themselves with corkscrew tails anchored in rotary motors. That may seem surprisingly mechanical for a microbe, but it is a system that has been wildly popular and conserved across billions of years of evolution.
To see what I mean, I encourage you to visit this ... Read More
How frequently do microbes exchange genes when living on a host? This question has been on my mind lately. Broadly speaking, the discovery of horizontal gene transfer (HGT) revolutionized the way we think about prokaryotic evolution. No more could we think only of inheritance via vertical descen...

Researchers at Princeton have discovered that cytomegalovirus manipulates a process called fatty acid elongation, which makes the very-long-chain fatty acids necessary for virus replication. Published in the journal Cell Reports on March 3, the research team identified a specific human enzyme--e... Read More
A new study by a team of researchers that includes University of Notre Dame scientists Joshua Shrout and Mark Alber provides new insights into the behavior of an important bacterial pathogen.
Alber, Vincent J. Duncan Family Professor of Applied Mathematics, and Schrout, an associate professor... Read More
Two experimental DNA vaccines to prevent Ebola virus and the closely related Marburg virus are safe, and generated a similar immune response in healthy Ugandan adults as reported in healthy US adults earlier this year. The findings are from the first trial of filovirus vaccines in Africa. Read More
Colonies of candida species:
Media: HiCrome Candida Differential Agar
principle: Perry and Miller (1) reported that Candida albicans produces an enzyme b -N-acetyl- galactosaminidase and according to
Rousselle et al (2) incorporation of chromogenic or fluorogenic hexosaminidase substrates ... Read More
Dear water-based life forms:
It is 24 degrees in Overland Park, Kansas and I am looking at a slide labeled "Giardia lamblia", part of a museum exhibit on water and human (over) use of water.
I see a greenish lump. I don't kno... Read More
These are two harmless lab strains of E. coli. One can ferment the sugar lactose into acidic byproducts and the other cannot. MacConkey media contains an indicator dye that turns from red to yellow when the pH is raised. The four pink streaks were drawn with a culture of the lactose fermenter (t... Read More
The enzymes that make copies of the DNA or RNA genomes of viruses – nucleic acid polymerases – can be placed into two broad categories depending on whether or not they require a primer, a short piece of DNA or RNA, to get going. The structure of the primer-independent RNA polymerase of hepatitis... Read More
