CDC: 75 Scientists Possibly Exposed to Anthrax

As many as 75 scientists working in government laboratories may have been exposed to live anthrax bacteria, the Centers for Disease Control and Prevention said on Thursday. The scientists are being offered treatment to prevent infection.

The potential exposure occurred after researchers worki... Read More

Poison-breathing bacteria

Buried deep in the mud along the banks of a remote salt lake near Yosemite National Park are colonies of bacteria with an unusual property: they breathe a toxic metal to survive. Researchers from the University of Georgia discovered the bacteria on a recent field expedition to Mono Lake in Calif... Read More

Caulobacter crescentus

The common waterborne bacterium Caulobacter crescentus reproduces asymmetrically. When a cell divides, one of its daughter cells is a free-swimming “swarmer,” powered by a hairlike flagellum. The other, “stalk” daughter cell is immobile, anchoring itself to a surface with one of nature’s stronge... Read More

Malnutrition: Starving Children Lack Crucial Gut Bacteria

When children are starving, the bacteria that live in their intestines may determine whether they can be saved, scientists working in Bangladesh are reporting. And they say it may become imperative to find a way to give children bacteria as well as food.

The study, done by researchers from Wa... Read More

This Psychedelic Art Is Actually Bacteria

This swirling mass may look like some kind of LSD trip, but it's actually fractal artwork created using bacteria.

Produced by Eshel Ben-Jacob—a scientist-cum-artist at Tel Aviv University—the piece came about thanks to two strains of bacteria which grew together in interesting and weird ways.... 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

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.

C... 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

Scientists Discuss The Reality Of A Zombie Apocalypse: Exclusive

Hollywood has amplified the idea of a zombie apocalypse for a long time, and the stories have grown increasingly popular in pop culture, particularly due to TV shows like ‘The Walking Dead‘ and movies like ‘World War Z.’

However, when you take science fiction out of the equation and add real-... 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

E.coli on MacConkey Agar (Mac)

Streak plate isolation of E. coli on MacConkey Agar grown for 24 hrs at 37 degrees. E. coli demonstrates strong lactose fermentation indicated by the bright pink halo, bile precipitant around the colonies, and pink colony growth. Read More

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

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

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
