Anrtibiotics Breed Drug-Resistant Bacteria In Pigs

After giving pigs a low-dose of antibiotics for just two weeks, researchers detected a drastic rise in the number of E. coli bacteria in the guts of the animals. And those bacteria showed a large jump in resistance to antibiotics.

The particular strain of E. coli detected in the study was not... Read More

Intestinal artillery launches anti-bacterial attack

The epithelial cells that line the intestines fire bacteria-fighting “bullets” into the gut, Vanderbilt University researchers have discovered.

The findings, featured on the cover of the April 10 issue of Current Biology, represent a new mechanism for defending the body against gut microbes.

Meningitis Vaccine Being Developed From Common Cold Virus

A leading cause for meningitis and septicemia in the UK is meningococcus B (MenB) bacterium infection. Healthy children can become severely ill within just a few hours if they contract meningitis or septicemia, as both illnesses develop randomly and with alarming speed. It often occurs in babies...

Built-in dengue virus killer found in humans

Scientists may have hit gold in their fight against dengue. They have located a human antibody that can neutralise and kill its virus within two hours.

Significantly, they have also identified a way to reproduce this antibody in large quantities, potentially opening the door to a cure for den... Read More

Schmallenberg virus: What, where, how?

As Schmallenberg virus is confirmed on 74 farms in the UK, our environment correspondent Richard Black looks at what the virus is, what it does and how it can be tackled.

What is Schmallenberg virus?
Schmallenberg virus is a disease of farm animals that was first seen last year in northern E... Read More

How medicine created a bacteria problem

On a warm afternoon in summer we were sitting in the lecture theatre, learning about germs. A microbiologist was showing us slides of enormously magnified bacteria (“God, this is like bug Imax!” said the girl behind me). The lecturer had a cold; he was coughing dramatically. After a prolonged bo... Read More

Worse Fears Realized? Completely Drug Resistant TB has emerged in India

Extensively Drug Resistant (XDR) Mycobacterium tuberculosis (MTB) was first encountered in 2006. Now as we enter 2012 we learn that a strain of MTB totally resistant (TDR) to all current antimicrobials has entered the Indian sub-continent . This new strain to India, TDR-MTB first emerged in ...

Slow-Motion Microbes Still Living off Dino-era "Lunch Box"

Buried under the seafloor for 86 million years, a bacterial community lives so slowly it's still surviving on a "lunch box" from dinosaur days, a new study says. (See marine-microbe pictures.)

It's been known since the 1990s that microbes can live trapped in ocean sediments for millions of ye... Read More

Building the perfect bug

This past February I was interviewed by the Australian Broadcasting Company on the topic of the Fouchier and Kawaoka experiments on avian influenza virus H5N1. The video, Building the Perfect Bug, has been released by Journeyman Pictures and includes interviews with S.T. Lai, Laurie Garrett, Mic... Read More

London prepares for Olympian disease-monitoring task

As the world’s athletes limber up for the forthcoming Olympic games in London, infectious-disease experts are preparing for their own trials. Their competition is with the diseases that millions of athletes, officials, media and spectators bring with them as they converge from across the globe o... Read More

Study Shows First N.C. Case of Feral Pig Exposure to Nasty Bacteria

A North Carolina State University study shows that, for the first time since testing began several years ago, feral pigs in North Carolina have tested positive for Brucella suis, an important and harmful bacteria that can be transmitted to people.

The bacteria are transmitted to humans by uns... Read More

Microbial Movers - A Small Things Considered Post

Elio Schaechter of Small Things Considered has authored an interesting post today about the motility of bacteria, specifically Paenibacillus, although he does highlight several other strains that swarm, glide or twitch.

"Microbes get around. They can be carried by the wind, by insects, or by ... Read More

Mosquito Immune System Engineered to Block Malaria

Researchers at the Johns Hopkins Malaria Research Institute demonstrated for the first time that the Anopheles mosquito's innate immune system could be genetically engineered to block the transmission of the malaria-causing parasite to humans. In addition, they showed that the genetic modificati... Read More

Selection-driven Gene Loss in Bacteria

Bacterial genomes differ dramatically in size: from 140Kb to 13Mb (those numbers might be off now...please let me know if something has broken the record. Yes, I know the lower estimate can change based on semantics, but there are a bunch in that range). Although we have some clues as to how sel... Read More

It's Raining Viruses

It’s true! Each year it rains viruses, more than a trillion of them per acre over thousands of forested acres in the USA. This is the work of the airborne arm of the USDA Forest Service, part of their efforts to reduce the devastation to hardwood forests caused by the imported gypsy moth, Lymant... Read More

How Bacteria Sense Salt Stress

Scientists' finding is a major breakthrough in understanding a decades-old problem of how bacteria detect environmental changes.

A team of scientists led by Assistant Professor Ganesh S Anand and Professor Linda J. Kenney from the National University of Singapore (NUS) Department of Biologica... Read More
