Airborne Environmental Isolate

Media is poured in bulk in our lab for classroom use. Although contamination is low we do see airborne contamination especially durning the rainy season. This is an unknown airborne environmental isolate on Mueller-Hinton agar exhibiting a single circular colony. White hyphal growth can be see... Read More

Deadly Human Pathogen Cryptococcus Fully Sequenced

DURHAM, NC - Within each strand of DNA lies the blueprint for building an organism, along with the keys to its evolution and survival. These genetic instructions can give valuable insight into why pathogens like Cryptococcus neoformans -- a fungus responsible for a million cases of pneumonia and... Read More

Second American infected with Ebola

A second American aid worker in Liberia has tested positive for Ebola, according to the Christian humanitarian group she works for.

Nancy Writebol is employed by Serving in Mission, or SIM, in Liberia and was helping the joint SIM/Samaritan's Purse team that is treating Ebola patients in Monr... Read More

Untapped Plant Microbiome Could Help Feed Billions

The Human Microbiome Project revealed tens of trillions of microbes residing in and on humans. Now scientists are taking a census of plant microbes—and not just the hundreds of billions found in soils. Distinct microbial communities live inside roots, on leaves and within flowers, and all in all... Read More

Progress in the fight against harmful fungi

A group of researchers at the Max F. Perutz Laboratories has created one of the three world's largest gene libraries for the Candida glabrata yeast, which is harmful to humans. Molecular analysis of the Candida glabrata fungus mutations led to the discovery of 28 new genes that are partly respon... Read More

UEA researchers discover Achilles’ heel in antibiotic-resistant bacteria

Scientists at the University of East Anglia have made a breakthrough in the race to solve antibiotic resistance.

New research published today in the journal Nature reveals an Achilles’ heel in the defensive barrier which surrounds drug-resistant bacterial cells.

The findings pave the way f... Read More

Why a bacterium got its curve — and why biologists should know

Drawing from his engineering background, Princeton University researcher Alexandre Persat had a notion as to why the bacteria Caulobacter crescentus are curved — a hunch that now could lead to a new way of studying the evolution of bacteria, according to research published in the journal Nature ...

Smallpox Virus Found In Unsecured NIH Lab

Scientists cleaning out an old laboratory on the National Institutes of Health campus in Bethesda, Md., last week came across a startling discovery: vials labeled "variola" — in other words, smallpox.

Under international convention, there are supposed to be only two stashes of this deadly vir... Read More

ASM GM 2014 - This Week in Virology #286: Boston TWiV Party

The American Society for Microbiology hosted a live podcast of This Week in Virology with Vincent Racaniello with co-host Alan Dove that includes guests Paul Duprex, Director of Cell and Tissue Imaging Core, Boston University, National Emerging Infectious Diseases Laboratories (NEIDL), and Ju...

Scientists Call for Investigation of Mysterious Cloud-like Collections in Cells

About 50 years ago, electron microscopy revealed the presence of tiny blob-like structures that form inside cells, move around and disappear. But scientists still don’t know what they do — even though these shifting cloud-like collections of proteins are believed to be crucial to the life of a c... Read More

Liquids


Liquids are capable of forming a gas-liquid interface: maintenance of the surface requires adequate pressure in the gas. Adequate in this instance means a gas pressure greater than the vaporisation pressure in the liquid. The gas pressure... Read More

D- Zone Test for phenotypic detection of Inducible clindamycin Resistance

A positive D test indicates that the presence of macrolide-inducible resistance to clindamycin produced by an inducible methylase enzyme that alters the common ribosomal binding site for macrolides, clindamycin and the group B streptogrammins (quinupristin). This cross-resistance, called the ML... Read More

Artificial Spleen Cleans Ebola from Blood

Researchers have developed a high-tech method to rid the body of infections — even those caused by unknown pathogens. A device inspired by the spleen can quickly clean blood of everything from Escherichia coli to Ebola, researchers report on September 14 in Nature Medicine.

Blood infections c... Read More

Scientists develop ‘electronic nose’ for rapid detection of C-diff infection

A fast-sensitive “electronic-nose” for sniffing the highly infectious bacteria C-diff, that causes diarrhoea, temperature and stomach cramps, has been developed by a team at the University of Leicester.

Using a mass spectrometer, the research team has demonstrated that it is possible to ident... Read More

Plant Pathogen Silences Host’s Immune Genes

As more and more information becomes available, one marvels (and also frets) at the sophisticated strategies that pathogens have evolved in order to evade their hosts’ defense mechanisms. Many pathogens of plants and animals deliver effectors into their hosts in order to suppress immune response... Read More

Esther Lederberg, Pioneer of Bacterial Genetics

“She did pioneering work in genetics, but it was her husband who won a Nobel price.” So said an obituary in the British newspaper The Guardian regarding Esther Lederberg, a North American microbiologist married to Joshua Lederberg from 1946 to 1966 [8]. Being married to and working along such a... Read More

Artificial magnetic bacteria "turn" food into natural drugs

Scientists from the University of Granada have successfully created magnetic bacteria that could be added to foodstuffs and could, after ingestion, help diagnose diseases of the digestive system like stomach cancer. These important findings constitute the first use of a food as a natural drug an... Read More

Incidence of childhood tuberculosis could be 25 percent higher than previous estimates

New estimates indicate that over 650,000 children develop tuberculosis (TB) every year in the 22 countries with a high burden of the disease -- almost 25 percent higher than the total number of new cases worldwide estimated by WHO in 2012. The research also suggests that about 15 million childre... Read More

The Jelly Roll of Life

We know that life on earth is incredibly diverse. It can survive deep in the trenches of the ocean and in the frozen permafrost of the arctic. Surely we have much to learn from the study of life, but we also have much to learn about the virus. Even though they are not considered living things, t... Read More
