A one-two punch by a gut parasite and viruses may help explain the mysterious decline in U.S. honeybees seen over the last four years.
Bees infected with both the fungal parasite Nosema ceranae and with any one of a handful of RNA viruses were much more likely to have come from hives on the d... Read More

Are you looking for help and more explanations about the proper controls for PCR and how to prepare standard curves? If you are, then you may want to attend this online seminar by expert, Ian Kavanagh, from Thermo Scientific R&D. He is going to give a 30 minute presentation on the subject Tuesda... Read More
A serious shortcoming of current influenza virus vaccines is the need to reformulate them every year or two as the virus undergoes antigenic drift. Many virologists have been captivated by the idea of a more universal vaccine that would endure longer, perhaps a decade or more. The identification... Read More
"Tests in four rhesus monkeys showed that seven daily injections cured 100 percent of them. And Geisbert said the researchers gave the monkeys an extremely high dose of Ebola."
The antivirus injections were given within an hour or so after infection. They are testing to see if they can extend... Read More
A team of scientists from government, academia and private industry has developed a novel treatment that protects mice from infection with the bacterium that causes tularemia, a highly infectious disease of rodents, sometimes transmitted to people, and also known as rabbit fever. In additional e... Read More
So much for the old warning flag on a stick.
Confronting an almost unwinnable battle against E. coli and other bacteria on public beaches, Chicago and some of its suburbs have taken the fight into the digital age.
From computer models that can predict conditions where bacteria will thrive,... Read More
The H1N1 virus outbreak appears to be contained and conquered in Alabama, according to a report by WAFF.

In a new study, a modified measles virus has shown potential for treating childhood brain tumour known as medulloblastoma.
Medulloblastoma is the most common malignant central nervous system tumour of childhood, accounting for about 20 percent of paediatric brain tumours.
These tumours ar... Read More
Some bacteria can influence the weather. Up high in the sky where clouds form, water droplets condense and ice crystal grow around tiny particles. Typically these particles are dust, pollen, or even soot from a wildfire.
But recently scientists have begun to realize that some of these little ... Read More
For nearly two decades, Public Enemy No. 1 for the food industry and its government regulators has been a virulent strain of E. coli bacteria that has killed hundreds of people, sickened thousands and prompted the recall of millions of pounds of hamburger, spinach and other foods.
But as eve... Read More

Could playing in the dirt make you smarter? Studies in mice suggest that it could.
Mice given peanut butter laced with a common, harmless soil bacterium ran through mazes twice as fast and enjoy... Read More
Jeffrey Fox of Microbe interviews Jian Ku Shang,materials scientist from the University of Illinois for the May 2010 issue.
The search for factors contributing to obesity has turned inward — all the way to the middle of the gut, where as many as 100 trillion bacteria hang out. The mix of microbes in a given person’s innards may — emphasize “may” — play some role in determining his tendency to put on pounds by governi... Read More
It is widely recognized that certain foodborne pathogens may persist in at least some sources of the food chain, while others may persist in different sources along the entire food chain. Watch Angel... Read More
This past week saw the report of the construction of the first chemically synthesized genome that was inserted into a pre-existing cell that then expressed the genome's phenotypic properties and was capable of continuous self-replication. The implications for microbiology can be profound. For... Read More
People with chronic obstructive pulmonary disease occasionally have flare-ups of their symptoms that require hospitalization. A study published Tuesday shows patients who received antibiotics within the first two days of hospitalization had better outcomes.
This is the second study in two da... Read More
New research from the United States Department of Agriculture (USDA) identifies a new potential cause for "Colony Collapse Disorder" in honeybees. A group of pathogens including a fungus and family of viruses may be working together to cause the decline. Scientists report their results May 25 at... Read More
