The vaccine used to protect against tuberculosis disease, bacillus calmette-guerin or BCG, also protects against tuberculosis infection, mycobacterium, as well as protecting against progression from infection to disease, finds new research. The BCG vaccine has been subject to numerous trials and... Read More
It came as a surprise to me recently to realize how much is known about the immune responses of plants and, moreover, how much there is to know. There is, I found, detailed molecular information about how our botanical cousins defend themselves against the onslaught of infectious agents. Perhaps... Read More
Growth of Serratia marcescens bacteria on bread: The Bacteria were suspended in tap water and placed on the bread. It was incubated foe 3 days in RT. Read More
A U.S. hospital caring for two Americans carrying the deadly Ebola virus has tapped biosafety experts to ensure doctors, nurses and other staff do everything needed to prevent the virus from escaping from an isolation ward in Atlanta.
The two patients, humanitarian aid workers who became infe... Read More
Bugs that can co-operate best with each other are most likely to be able to jump to new species, including humans, a new study shows.
Bacteria interact by releasing molecules to help them adapt to their environment – for example, when killing competing infections in their victim. They co-ord... Read More
The body’s assailants are cleverer than previously thought. New research from Lund University in Sweden shows for the first time how bacteria in the airways can help each other replenish vital iron. The bacteria thereby increase their chances of survival, which can happen at the expense of the p... Read More
On Friday afternoon, the federal Centers for Disease Control and Prevention posted a guide explaining how hospitals should manage Ebola patients. Hospital workers entering a patient's room should wear:
- Gown (fluid resistant or impermeable)
- Eye protection (goggles or face shield... Read More
The Ebola outbreak is out of control in Africa, but it is not a global threat, why? Read More

After recording TWiV 296 with Linfa Wang, we drove to a nearby golf course. There we watched a colony of grey-headed flying foxes awaken and fly into the night.
Vincent visits the Australian Animal Health Laboratory in Geelong, Australia and speaks with Linfa about his work on bats and bat viruses.
Hosts: Vincent Racaniello
Scientists for Science are confident that biomedical research on potentially dangerous pathogens can be performed safely and is essential for a comprehensive understanding of microbial disease pathogenesis, prevention and treatment. The results of such research are often unanticipated and accrue... Read More
Beautiful scanning electron microscopy images.
"For 2 decades we have been devoting our work to the visualization of the previously unknown and invisible. Detailed, aesthetic, and scientifically correct we present an access into the microscopic world of biology, medicine, chemistry, technolog... Read More
Here’s what we know about white-band disease: It has already killed up to 95 percent of the Caribbean’s reef-building elkhorn and staghorn corals, and it’s caused by an infectious bacteria that seems to be transmitted through the water and by coral-eating snails.
Here’s what we don... Read More
Wake Forest sophomore receives prestigious award to study dangerous bacteria.
The notion that trillions of bacteria are packed into the human body is enough to give anyone the heebie jeebies.
But not all bacteria are bad, said Hannah Martin, a rising sophomore. On the contrary, there are ... Read More
The Ebola outbreak continues to roil West Africa, with the World Health Organization announcing Thursday that the death toll has climbed to 729 in Guinea, Sierra Leone and Liberia. More than 1,300 people are infected.
To help limit the spread of the disease the U.S. Centers for Disease Contro... Read More
A flu virus acts like a Trojan horse as it attacks and infects host cells. Scientists at Rice University and Baylor College of Medicine have acquired a clearer view of the well-hidden mechanism involved.
Their computer simulations may lead to new strategies to stop influenza, perhaps even a o... Read More
An experimental vaccine protected 100 percent of animal models against the highly infectious and virulent bacterium, Clostridium difficile, which causes an intestinal disease that kills approximately 30,000 Americans annually. The research is published ahead of print in Infection and Immunity.

For scientists tracking the deadly Ebola virus in West Africa, it is not about complex virology and genotyping, but about how contagious microbes - like humans - use planes, bikes and taxis to spread.
So far, authorities have taken no action to limit international travel in the region. The ai... Read More
