Biological differences between the sexes could be a significant predictor of responses to vaccines, according to researchers at the Johns Hopkins Bloomberg School of Public Health. They examined published data from numerous adult and child vaccine trials and found that sex is a fundamental, but ... Read More
The University of Wisconsin-Madison has revoked a scientist's laboratory privileges for five years and paid a $40,000 sanction over unauthorized experiments involving Brucella, a bacterium that can infect cattle and humans and is highly regulated by the federal government. Read More
On 11 May 2010 Bernhard-Nocht-Institute for Tropical Medicine in Germany reported that additional laboratory analyses conducted both in Germany and South Africa on the German tourist who was preliminarily diagnosed with Rift Valley Fever (RVF) following her return from South Africa, was in-fact ...

Trillions of bacteria might help clean up the Gulf oil spill, a specialized company reports.
Osprey Biotechnics, Inc., a pioneer in breeding beneficial bacteria, says it estimates that 55 gallons of the product it calls Munox would treat 36.5 square miles of Gulf waters. Slightly more than 10... Read More
Microbiologists at UT Southwestern Medical Center, working with the Department of Agriculture, have identified a potential target in cattle that could be exploited to help prevent outbreaks of food-borne illnesses caused by a nasty strain of Escherichia coli.
In the study, available online an... Read More
As the recall of tainted romaine lettuce expands, many plates could be devoid of the crisp veggie in an effort to stay healthy. That might be a good idea, according to experts who say that washing produce, even very carefully, may not remove all the bacteria present. Read More
Scientists are reporting success in a first attempt to silence the biochemical conversations that disease-causing bacteria use to marshal their forces and cause infections. In a study in ACS' monthly journal, Biomacromolecules, they describe use of specially designed plastic-like materials to so... Read More
Assistant architecture professor Ginger Krieg Dosier recently unveiled a new breed of biologically “grown” bricks that are durable, sustainably manufactured, and easily produced from readily available materials. Called “Better Bricks,” the building material can be “grown” from sand, common bact... Read More
Atrazine, watch out: There's a killer from the future tracking you down.
Scientists working in Georgia have engineered a common bacteria that will, in the lab, detect and seek out atrazine, a controversial herbicide sprayed over cornfields and sugar plantations across the United States.
An... Read More
With an oil spill onslaught headed for Gulf shores, you might wonder — whatever happened to those laboratory miracle oil-eating microbes for an instant clean-up?
"They don't exist," says microbiologist Ronald Atlas of the University of Louisville. "They only work in a lab flask. They have nev... Read More
An international team led by a University of Cincinnati (UC) researcher has shown how a bacterial community evolves to survive hostile host defenses in the body.
The team, led by Malak Kotb, PhD, chair of UC's of molecular genetics, biochemistry and microbiology department, analyzed the evolu... Read More
Here's a great mother's day song from a biologist's perspective. Musically it is similar to a They Might Be Giants song. Enjoy. Read More
Shoppers who go to the drug store to fill their Plavix prescriptions or pick up a bottle of prenatal vitamins may soon find themselves reconsidering these mundane purchases.
The reason? A new genetic testing kit that will hit the shelves of select Walgreens stores later this month. The test ... Read More
Lamentablemente esta semana El Mundo de los Microbios no estara accesible debido a problemas estudiantiles en nuestra institucion, la Universidad de Puerto Rico. Una huelga estudiantil que ha tenido la universidad bloqueada por los ultimos 19 dias no nos ha permitido el libre acceso a nuestr... Read More
The Patriot Act and the Bioterrorism Preparedness Act were passed in 2001 and 2002. These laws in part cover research on pathogens and toxins thought to have potential as bioweapons.
The Bush administration increased funding for research on such toxins and pathogens—but the laws added a great... Read More
Thirty years ago, the biologist Bruce S. Baker discovered that the gender of a fruit fly is determined not by a hormone, but by the expression of a gene called doublesex in individual cells. Female fruit flies express one form of the gene in their cells, while males express another.
Now, wit... Read More
Until the late 19th century, diphtheria was a gruesome killer with no known cause and many ineffective treatments. In 1874, The New-York Times printed an advertisement for a medicine that would cure not only diphtheria, but also corns, bunions and “pains in the loins and back.” The same year, a ... Read More
