Fear Not the Fecal Transplant

Officially called a fecal microbiota transplantation, or FMT, the procedure involves the insertion of a small, diluted sample of stool from a donor into the colon of a recipient. (Clearly disgusting.) The swap imports a healthy community of bacteria, the intestinal microbiota, into the system of... Read More

World changing technology enables crops to take nitrogen from the air

A major new technology has been developed by The University of Nottingham, which enables all of the world’s crops to take nitrogen from the air rather than expensive and environmentally damaging fertilisers.

Nitrogen fixation, the process by which nitrogen is converted to ammonia, is vital fo... Read More

'Bacterial raincoat' found to protect bacteria from the environment

Research led by scientists at the University of Dundee has uncovered the workings of a 'bacterial raincoat' that helps to protect bacteria from the changing environment in which they live.

Many bacteria grow in large communities called biofilms, where the cells work together and produce a sti... Read More

Virus to Control Potato Moth

New biological insecticides have emerged in recent years which make use of so-called "entomopathogenic" viruses that are harmful to insects, in particular the baculovirus. To identify the virus in this family that will most effectively control the Guatemalan potato moth, the French-Ecuadorian re... Read More

Fine Reading: The Second Skin – Ecological Role Of Epibiotic Biofilms On Marine Organisms

In contrast to air, the ocean represents a benign environment for most living organisms: With the exception of some harsh marine environments, the means of physicochemical properties are generally not far off the optimum of most species and their fluctuations are moderate, rarely exceeding biolo...

The Planctomycetes, Tricky Gram-negatives Awaiting Genetic Manipulation

Members of the bacterial phylum Planctomycetes (click here and here) inhabit a wide variety of environments throughout the world. What makes them special is that in the mind of some investigators they possess a mix of eukaryotic and prokaryotic structural attributes. Now that is something pretty... Read More

Horizontal transfer of antibiotic resistance genes among gram negative bacteria in sewage and lake water and influence of some physico-chemical parameters of water on conjugation process

Transfer of antibiotic resistance genes among gram negative bacteria in sewage and lake water and easy access of these
bacteria to the community are major environmental and public health concern. The aim of this study was to determine transfer of the
antimicrobial resistance genes from resista... Read More

Purple bacteria on Earth could survive alien light

Purple bacteria contain pigments that allow them to use sunlight as their source of energy, hence their color. Small as they are, these microbes can teach us a lot about life on Earth, because they have been around longer than most other organisms on the planet. University of Miami (UM) physicis... Read More

Seeking solutions to viral migration

Although seldom fatal, persistent infection by chikungunya virus (CHIKV) afflicts patients with joint pain lasting months or even years. This insect-borne virus has received relatively little scientific attention in the 50 years since its initial description in African patients, but researchers ... Read More

Hope for Hep C cure no excuse for risk-taking, expert warns

Professor Geoff McCaughan, head of the Liver Immunobiology Program at Sydney's Centenary Research Institute, says preliminary results of a newly developed oral treatment regime for liver transplant patients with Hepatitis C were showing promising results.

"We are starting to see some dramatic... Read More

Copper nanoparticles protect food from bacteria

Scientists have proposed adding copper nano-particles into food packaging materials on this basis that this could help prevent a variety of foodborne diseases.

It has been known for centuries that copper has antimicrobial properties. For example, it was observed in Roman times that water cont... Read More

Lab-work without a lab: culturing bacteria in rural areas with limited resources

In order to isolate, study and efficiently treat a bacterial outbreak, it is vital to be able to grow, store and identify the particular strains of bacteria that cause the disease. While this can be a fairly simple task in a well stocked laboratory, it’s a lot harder to achieve out in the field,... Read More

Condoms May Boost Beneficial Vaginal Bacteria

In addition to preventing unwanted pregnancies and the spread of sexually transmitted diseases, condoms may help good bacteria in the vagina flourish, a new study from China shows.

Sexually active women in the study who used condoms had larger colonies of beneficial microbes in their vaginas ... Read More

Pan-drug resistance and microbial genome

In recent century, because of excessive use and abuse of antibiotics both in community and hospitals gram negative and positive bacteria are adapted on to this hostile environment and many strains (Clones) are exhbiting resistance to multiple antibiotics (MDR). These strains are widely distribut... Read More

Bacteria May Play Role In Pancreatic Cancer

Bacterial infections may play a role in triggering pancreatic cancer, according to recent research.

A growing number of studies suggest a role for infections --primarily of the stomach and gums -- in pancreatic cancer. The disease is a particularly deadly cancer, which the American Cancer Soc... Read More

Burrowing bacteria may end need to fertilise plants

You may never need to put fertiliser on your plants again.

Scientists have invented a technology that allows plants to fertilise themselves by obtaining nitrogen from the air.

Almost all plants rely on nitrogen from the soil to grow, but few are able to use it directly from the air and so ... Read More

How to Survive as a Biofuel Maker: Sell Algae to Bakers [Slide Show]

The ice cream and caramels are delicious, but it's the brioche that really convinces you eating algae could be a winning idea. The oily, yellow, flour-like residue of wrung out algae—dubbed "algalin" by its marketers—can easily replace the butter and eggs in prototypical French pastry bread.

Mers: New virus 'not following Sars' path'

The new Mers virus, which has killed half of those infected, is "unlikely" to reach the same scale as Sars, ministers in Saudi Arabia say.

Most of the 90 Mers cases reported so far have been in Saudi Arabia.

Mers is from the same group of viruses as the common cold and Sars, which killed 7... Read More
