Although the recent epidemics of bubonic plague in China, India, and other parts of the world have been always associated with outbreaks of the same disease among rats, the historical study of plague throughout the world reveals the singular fact that previous to 1800 very few references to a co...

The cholera epidemic that has raged across this country is claiming fewer victims, with a sharp drop in new cases everywhere from the shimmering rice fields of the Artibonite Valley to the crowded urban slums.
It is a welcome development, but tinged with doubt: It's not yet known whether the ... Read More
An Ebola-like hemorrhagic fever has killed three people in western India and dozens of doctors will screen a community of about 16,000 people in efforts to contain the disease, a state health minister said this past Wednesday.
India's National Institute of Virology later confirmed that the th... Read More

This episode: Flu vaccine made by bacteria!
Giving plasma from someone who has recovered from an infection to a person who is acutely ill with that same infection is an old medical trick. Researchers reported Wednesday that the therapy can work on people with severe H1N1 influenza.
Researchers in Hong Kong gave plasma donated from pati... Read More
The virus that causes Crimean-Congo haemorrhagic fever (CCHF) is slow moving and will not spread across the country as fast as the H1N1 swine flu virus, experts have said. However, the mortality rate among those affected by Congo virus will be far more than H1N1.
In an exclusive interview to ... Read More
Listen to this...it's incredible.
The pharma establishment is stomping on Dr. Andrew Wakefield in the same way they stomped on Peter Duesberg of UC Berkeley. In both cases Dues and Wakefield got it right, and the pharma establishment is shieldin... Read More
The American Society for Microbiology has released a document designed to assist clinical laboratories in dealing with the emerging pathogen, Cryptococcus gattii.
The document titled A Quick Guide to the Significance and Laboratory Identification of Cryptococcus gattii was prepared by the PSA... Read More
In a new paper published Jan. 21 in the journal Science, a team of researchers led by Microbiology and Immunology professor Blossom Damania, PhD, has shown for the first time that the Kaposi sarcoma virus has a decoy protein that impedes a key molecule involved in the human immune response.

A handful of bacterial genes crucial to survival were successfully replaced by artificial ones in a new synthetic-biology experiment.
It’s not clear how the synthetic genes rescued the doomed E. coli bacteria, which had several important sequences of DNA knocked out of its genome. But scienti... Read More
To defend microbial attacks, the human body naturally produces a group of antibiotics, called defensins. An interdisciplinary team of biochemists and medical scientists has now deciphered the mechanism of action of a defensin, hitherto looked upon as exhibiting only minor activity. Their results...

The fate of smallpox is once again on the agenda of the World Health Organization, which is considering whether to destroy the last known samples of the deadly virus, currently held in labs in the U. S. and Russia.
Some countries want to get rid of the smallpox strains so they can't be used a... Read More
Hearing loss in a child may have links to a virus that Mom got while she was pregnant, according to a new study.
In kids that had some degree of hearing loss, about 9 percent also had cytomegalovirus (CMV) at birth, says a new study in the Archives of Otolaryngology-Head and Neck Surgery.

Chemists at Bar-Ilan University in Israel say they have developed and successfully tested "killer paper" coated with silver nanoparticles--each roughly 1/50,000 the width of a human hair--that can fight bacteria such as E. coli and S. aureus.
Described in the American Chemical Society journal... Read More

Scientists at The Scripps Research Institute have found that a known enzyme in cells protects against measles virus, likely by altering the virus's genetic material, RNA. Cells lacking the enzyme become highly vulnerable to the virus's destructive effects. The enzyme also protects against severa... Read More
Chris Upton, a contributor to the virology toolbox, has raised an important point about multiplicity of infection:
Perhaps this is a place to bring up particle to pfu ratio? The above is great for when talking about phage, for example, when the ratio approaches 1. But with something like poli... Read More
Do video games change behavior? This question may be the subject of debate for years, but researchers have now shown the answer to be yes—for microorganism behavior, at least.
A research group led by Stanford bioengineering professor Ingmar Riedel-Kruse has developed several real video games,... Read More
