New discovery: Microbes can create dripstones

According to new research humble, microscopic organisms can create dripstones in caves. This illustrates how biological life can influence the formation of Earth’s geology - and the same may be happening right now on other planets in space.

According to traditional textbooks dripstones are cr... Read More

A Tale of Two Strategies

Bacteria are for the most part gregarious organisms, living predominantly in dense communities consisting of multiple strains. In fact, the majority of infectious bacteria occur as multi-layered structures called biofilms, many of which are composed of multiple types of bacteria. As one can imag... Read More

Scientists Finally Catch On to Social Media

In 2011, Emmanuel Nnaemeka Nnadi needed help to sequence some drug-resistant fungal pathogens. A PhD student studying microbiology in Nigeria, he did not have the expertise and equipment he needed. So he turned to ResearchGate, a free social-networking site for academics, and fired off a few e-m... Read More

Sauerkraut: bacteria making food

Last week my husband needed some jars for cooking purposes. Tesco sell jars for somewhere around £3 each. However they also sell large jars full of sauerkraut for £1 each. Which means that last weekend we had an awful lot of sauerkraut to try and get through.

I’m not a great fan of sauerkraut... Read More

Wolbachia Genome Reduction, Phage WO, and Reproductive Parasitism

Abstract:

Wolbachia are maternally transmitted endosymbionts that often alter their arthropod hosts’ biology to favor the success of infected females, and they may also serve as a speciation microbe driving reproductive isolation. Two of these host manipulations include killing males outrigh... 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

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.

Farmers Fight Poisonous Wheat Fungus with Cleaning and Waiting

Dave Wiechert of Nashville, Illinois, does good business most years cleaning seed for farmers in preparation for planting season. But this year, Wiechert is doing big business after harvest: cleaning fungus off wheat so farmers can sell it.

The "head scab" fungus can produce vomitoxin, a chem... Read More

‘Wormy’ Pills Might Fend Off Autoimmune Diseases

Scientists have identified peptides from parasitic hookworms that can calm the body’s immune response and perhaps pave the way to treat autoimmune diseases.

Experts believe the peptide molecules could help explain why worm infections can effectively treat diseases such as multiple sclerosis, ... 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

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

Experimental Vaccine For Chikungunya Passes First Test

Scientists have taken the first steps to developing a vaccine for chikungunya — an emerging mosquito-borne virus that has infected more than a half million people in the Western Hemisphere this year. About 600 Americans have brought the virus to 43 states.

The study was small. Only 25 people ... Read More

Microbiology: Microbiome science needs a healthy dose of scepticism

Explorations of how the microscopic communities that inhabit the human body might contribute to health or disease have moved from obscure to ubiquitous. Over the past five years, studies have linked our microbial settlers to conditions as diverse as autism, cancer and diabetes.

This excitemen... Read More

Should experimental drugs be used in the Ebola outbreak?

Risks and benefits of unproven treatments, as World Health Organization approves use in crisis.

Two Liberian doctors are set to become the first Africans to receive an experimental drug against the Ebola virus. The news comes as the World Health Organization concludes that it is ethical to us... Read More

Ebola crisis: A doctor's view from Sierra Leone

West Africa's Ebola epidemic, the deadliest on record, presents particular challenges for medical staff. Here, Irish doctor Gabriel Fitzpatrick describes working for Medecins Sans Frontieres (MSF) at the centre of the outbreak in Sierra Leone:

MSF constructed a special Ebola treatment centre ... Read More

MERS virus detected in air samples from Saudi camel barn

Saudi scientists have found gene fragments of the deadly Middle East Respiratory Syndrome (MERS) virus in air from a barn housing an infected camel and say this suggests the disease may be transmitted through the air.

MERS, a serious respiratory illness caused by a virus known as a coronaviru... Read More
