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.
Until this year, the world had recorded 1,640 deaths from Ebola since the virus was discovered in 1976.
Then Ebola appeared in West Africa.
So far this year, 887 people have died of Ebola in West Africa, the World Health Organization said Monday.
To put that into perspective, more than ... 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
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
Rapid expansion of this species, which is more aggressive than the species that is now spreading chikungunya into the Caribbean, is worrying scientists.
In the past few months, passengers at North American airports have been warned that travel to the Caribbean might result in an unwanted souv... 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
Bacteria inside your mouth drastically change how they act when you're diseased, according to research using supercomputers at the Texas Advanced Computing Center (TACC). Scientists say these surprising findings might lead to better ways to prevent or even reverse the gum disease periodontitis, ... Read More
A smoldering debate about whether or not researchers should ever deliberately create superflu strains and other risky germs in the interest of science has flared once again.
Proponents of the work say that in order to protect the public from the next naturally occurring pandemic, they have to... 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
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
Bacteriophages are viruses that infect bacteria, and in the great war between humans and pathogenic bacteria they can act as allies for both sides. Phages that destroy their host bacteria can be used as antimicrobial therapy, complementing or replacing antibiotics. On the other hand as phages ar... 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
One of the most common types of bacterial infection might soon give doctors and nurses fewer sleepless nights, thanks to a discovery made by scientists at Trinity College Dublin. The scientists used X-ray crystallography techniques to provide a blueprint of the cellular machinery used by Pseudom... Read More
World Health Organization announcement could shift focus to basic public health.
The escalating Ebola outbreak in West Africa poses an international threat and all countries must work together to contain it, the World Health Organization (WHO) said today (8 August). The announcement comes ami... Read More
The TWiV gang answers follow-up questions about the Ebola virus outbreak in West Africa, then discuss treatment of disseminated multiple myeloma with oncolytic measles virus.
Scientists are pursuing injections or intravenous infusions of broadly neutralizing HIV antibodies (bNAbs) as a strategy for preventing HIV infection. This technique, called passive immunization, has been shown to protect monkeys from a monkey form of HIV called simian human immunodeficiency vir... Read More
Scientists believe babies are born with digestive systems containing few or no bacteria. Their guts then quickly become colonized by microbes — good and bad — as they nurse or take bottles, receive medication and even as they are passed from one adoring relative to another.
However, in infant... Read More
Normal microorganisms in the intestines appear to play a pivotal role in how the HIV virus foils a successful attack from the body’s immune system, according to new research from Duke Medicine.
The study, published Aug. 13, 2014, in the journal Cell Host & Microbe, builds on previous work fro... Read More
Important ingredients: 6.5% salt, dextrose, bromcresol purple
Differential/Selective: used to test for salt tolerance and can be used to identify enterococcal group D streptococci. NaCl is a selective agent and those organisms that can grow in higher salt concentrations also ferment the dextro... Read More
This Week in Virology, the podcast about viruses, celebrates its 300th episode on Tuesday, August 26, 2014 with a live recording at the Washington, DC headquarters of the American Society for Microbiology. This special episode w... Read More
