Healthy Lung Microbes Keep Mice Breathing Easy

Like humans, mice start life with sterile lungs that soon get colonized by microbes, which appear to protect the lung tissue from an asthma-like reaction in the presence of dust mites.

Human cells are outnumbered ten-to-one by the microbes that thrive in and on us. Now a study finds that the ... Read More

1 in 25 patients gets infection in hospital

When antibiotics first started being used in the 1940's they were considered a "miracle drug". It seemed that bacterial infections would no longer be a problem for the world. However, recently, one gene is making it seem as though the end of antibiotics is at hand. This gene is New Delhi metallo... Read More

Pseudomonas paints a picture!

A student and I painted with bacteria and this is what happened! We used a method similar to that used by artist Sarah Roberts (UK) and microbiologist Simon Park.

Motility agar plates were prepared and painted with watercolor paint before inoculation with P. aeruginosa. After 7 days at room t... Read More

Pertussis on Rise in U.S. Elderly - ICAAC 2013

Pertussis, a respiratory illness commonly known as whooping cough, is a very contagious disease caused by a type of bacteria called Bordetella pertussis. Since the early 1980s, there has been an overall trend of an increase in reported pertussis cases. In this video participants discuss the resu... Read More

Lab-on-a-Chip Tracks Down 'Most Wanted' Microbe

A diagnostic tool that’s about the size of a credit card has identified a highly prized gut microbe.

The microbe contains interesting genetic sequences, but it has proven challenging to culture in the lab.

Researchers used the device, called SlipChip, to isolate microbes from a patient’s g... Read More

Breastfeeding increases prevalence of Lactobacilli and Bifidobacteria in infants

Breastfeeding until at least nine months of age increases prevalence in the gastrointestinal tract of Lactobacilli and Bifidobacteria, species which are known to contribute to development of a healthy immune system, according to a paper describing the establishment of the intestinal microbiota d...

Extensively drug-resistant tuberculosis hovers threateningly at Australia’s door

Hello dear TWIM'ers!

Firstly I would like to apologize in advance for my poor English skills since my native language is Portuguese. This past few years much has been the attention towards drug resistant bacteria. I am aware that a couple of your podcast touched this subject, but a few weeks ... Read More

Fla. dolphins harbor potentially deadly bacteria

One in every three bottlenose dolphin tested in the Indian River Lagoon on Florida's Atlantic coast has antibodies to a bacteria that can make them more vulnerable to other deadly infections, according to a new study.

The finding comes as researchers struggle to figure out what has caused a r... Read More

New Research on Antibiotic-Resistant Bacteria, Pressure Ulcers, Severe Alcoholic Hepatitis, and More

Two million people suffer antibiotic-resistant infections yearly, and 23,000 die each year as a result. Most of these infections occur in the community, but deaths usually occur in healthcare settings. Cost estimates vary but may be as high as $20 billion in excess direct healthcare costs.

The Strange Connection Between Germs and Sherlock Holmes

Sherlock Holmes was as much a scientist as a detective. Maybe that’s because his creator, Arthur Conan Doyle, was influenced by a detective of science: Robert Koch, a German doctor who helped prove the existence of germs. In his new book, The Remedy, Thomas Goetz traces connections between the t... Read More

Researchers Discover Possible New Target To Attack Flu Virus

Scientists at The University of Texas at Austin have discovered that a protein produced by the influenza A virus helps it outwit one of our body's natural defense mechanisms. That makes the protein a potentially good target for antiviral drugs directed against the influenza A virus.

Rising star uses paper to tackle food-borne diseases

A University of Alberta researcher’s star is rising thanks to her idea to detect deadly pathogens such as E. coli using a paper device only slightly larger than a postage stamp.

Frédérique Deiss, a post-doctoral fellow in the Faculty of Science, is working on ways to help detect food- and wat... Read More

Human Sweat's Filthy Attributes Stop Bacteria-Fighting Brass

Human sweat is actually much dirtier and bacteria-filled than we initially thought. Scientists have found that sweaty hands can reduce the effect that brass objects have of fighting bacteria. Brass objects can be found in hospitals and schools and sweat can fight off its abilities just an hour a... Read More

What’s eating you? The first food web inside humans suggests potential new treatments for infection

Imagine going to the doctor with an infection and being sent home with a course of drugs. Unknown to your doctor you actually have two infections. If you take the drugs will the other infection go away by itself? What if you take the drugs and the other infection gets worse? This quandary faces ... Read More

Swirling and whirling: the movement of spherical bacteria

Research on bacterial movement tends to focus on the rod-shaped bacteria. With the aid of small waving flagella, each bacterial cell can push itself in the direction it wishes to go. They can also move in groups, forming large swarms that ripple and slide their way across Petri dishes. Spherical... Read More

ASM GM 2014 - Where Pathogens Can Linger on Airplanes

Many air travelers are concerned about the risks of catching a disease from other passengers given the long time spent in crowded air cabins. New research shows disease-causing bacteria can linger on surfaces commonly found in airplane cabins for days, even up to a week. Participants discuss ... Read More
