If you know anything about snakes you might be familiar with snake inclusion body disease, or IBD. This transmissible and fatal disease affects snakes of a variety of species but has been best studied in boas. The name comes from the presence of large masses (inclusions) in the cytoplasm of cell... Read More
A bacteria that is known to be associated with more than 80% of gastric and doudenal ulcers, may be associated with infant colic. The bacteria, Helicobacter Pylori (H.pylori), is found in the lining of the of the stomach wall.
Dr. Abdelrazak Mansour Ali from Al-Azhar University in Cairo, Egyp... Read More
A new, nanometer-sized biosensor can detect a single deadly bacterium in tainted ground beef. How? Researchers attached nanoparticles, each packed with thousands of dye molecules, to an antibody that recognizes the microbe E. coli O157:H7. When the nanoball-antibody combo comes into contact with... Read More
A year has passed since the last reported case of poliomyelitis in India, which occurred on 13 January 2011 in a two year old girl in Howrah, West Bengal. Read More
A while ago, Dick made a comment along the lines that Sir... Read More

If you have a mac with Apps, please go to the app store and download cell images.... I think you'll have a great time going through them.
One other thing - I listened to your show on science reform with interest but I ... Read More
The discovery of microbes in any icy lava tube in Oregon raises hope that similar microorganisms could survive in the very similar conditions to be found on Mars.
The microbes are coping with near-freezing temperatures and low levels of oxygen, and can even grow in the absence of organic food... Read More
If you make your own yogurt, there's a chance your yogurt could outlive you.
That's because some bacteria that grow and feed on the sugar in milk – the process that ferments milk into yogurt — can procreate indefinitely in new generations of yogurt.
But not all yogurts have these immortal po... Read More
As a pediatrician, I spend a lot of time looking for bacteria that might be making my patients sick. Some well-known illnesses that are caused by bacteria include strep throat, ear infections, Lyme disease and conjunctivitis (pinkeye). Bacteria are also responsible for acne, cavities and body od...

The problem with antibiotics? We’re running out of them.
Over the last half-decade, our arsenal of powerful bacteria-killing medicines has slowly (though in biological time, rapidly) been depleted as nature, through evolution, outwits our efforts to develop chemical tools that can save us fro... Read More
The Obama administration has announced a new policy to handle the risks posed by legitimate biological research that could, in the wrong hands, threaten the public.
The move comes in response to a huge debate over recent experiments on bird flu virus that got funding from the National Institu... Read More
Shiga toxin is an extremely potent toxin that is produced when the bacterium contains a bacteriophage carrying the toxin gene. It is closely linked with Haemolytic Uraemic Syndrome and acute renal failure in children. After ingestion via contaminated food or water the E. coli bacteria colonize t... Read More
One of two papers on avian influenza H5N1 virus that caused such a furor in the past six months was published today in the journal Nature. I have read it, and I can assure you that the results do not enable the construction of a deadly biological weapon. Instead, they illuminate important requir... Read More
Reporting in the Proceedings of the National Academy of Sciences, a team of Jefferson immunologists found that a specialized "human immune system" mouse model closely mimics a person's specific response and resolution of a tick-borne infection known as relapsing fever, caused by the bacteria Bor...

"Take a listen to four very savvy and plain-talking biologists chatting on their business at an inside-the-academy site called This Week in Microbiology, and more specifically at episode TWiM 32. There host and Columbia U. faculty member Vincent Racaniello and two colleagues talk of arsenic and ... Read More
Harvard Medical School researchers have engineered a photosynthetic cyanobacterium to boost sugar production, as a first step towards potential commercial production of biofuels and other biotechnologically and industrially useful carbon compounds. As feedstock producers, cyanobacteria have adva... Read More
Just a quick note to say how much I enjoy TWiM, and in particular, how much I enjoyed episode 32 featuring Rosie Redfield. I don't know how you find time to do this, but I'm gl... Read More
The Centers for Disease Control and Prevention has confirmed three mildly ill children with viruses similar to the swine-origin influenza A (H3N2) viruses identified in three other states. These viruses contain the "matrix (M) gene segment" from the 2009 "Swine Flu" pandemic known as H1N1 virus.... Read More
Researchers use stealthy nanoscale particles to infiltrate vaginal mucus and keep herpes at bay in mice.
Tears and a runny nose can be unpleasant on a windy day, but these mucosal secretions play a vital role in protecting the body from viruses and other malicious microbes. Unfortunately, muc... Read More
You’ve probably heard of "chickenpox parties," where parents get unvaccinated kids together (in the home of an infected child) in the hopes they'll catch the disease. They think making their kids suffer through the disease will help them develop stronger immunity than immunization would provide.... Read More
