Tara Smith joins the TWiEBOVsters to discuss the Ebola virus outbreak in west Africa, spread of the disease to and within the US, transmission of the virus, and much more.
Strain: Pseudomonas aeruginosa PA14
Medium: M8 minimal medium agar plates
Incubation Conditions: 48 hours at 37°C
Pseudomonas aeruginosa is a gram-negative, rod-shaped and monoflagellated bacterium that has an incredible nutritional versatility. Swarming motility, a flagellum-dependent behavi... Read More
As many as 75 scientists working in government laboratories may have been exposed to live anthrax bacteria, the Centers for Disease Control and Prevention said on Thursday. The scientists are being offered treatment to prevent infection.
The potential exposure occurred after researchers worki... Read More
Vincent, Dickson, and Daniel present a new case study, and discuss the effect of chronic malaria infection on wild warbler life span and telomere degradation.
Tuberculosis (TB) represents a serious public health problem: 8.7 million cases in 2001 and over 1.4 million deaths per year. In 2006, extensively drug-resistant (XDR) tuberculosis has been confirmed in 84 countries, heralding the possibility of virtually untreatable tuberculosis. The emergence ... Read More
The Grand Masters of the TWiV discuss Ebola virus transmission, air travel from West Africa, Ebola virus infectivity on surfaces, the Dallas Ebola virus patient, and Ebola virus in dogs.

Because all animal viruses initiate infection by binding to a receptor on the cell surface, this step has long been considered a prime target for antiviral therapy. Unfortunately, drugs that block virus attachment to cells have never shown much promise. Another approach, which is to ablate the r... Read More
In this post from my Microbiology/Education blog, I wish everyone a lovely day of food, fellowship, and fireworks. My laboratory brings you our own "fireworks" through bioluminescence! Read More
Isolated colony of Mycobacterium smegmatis grown on TSA for 96 hrs at 37 degrees C. Margin is lobate with an irregular-rhizoid form. Image taken using transmitted light. Read More
The Global Virus Network (GVN) announced today the launch of a Task Force on HTLV, Human T-Lymphotropic Virus (HTLV), the world's first known human retrovirus and only known leukemia-causing virus. Experts from 11 countries*, led by Dr. Robert Gallo, GVN co-founder and scientific director and di... Read More
Two years ago, the virus didn't even have a name. A year ago it had infected roughly 50 people, half of whom died. Now, Middle East Respiratory Syndrome has been confirmed in more than 600 people, and killed nearly 30 percent of its victims.
Originating on the Arabian Peninsula, MERS has been... Read More
Scientists at The University of Texas at Austin have discovered that a protein produced by the influenza A virus helps it outwit one of our body's natural defense mechanisms. That makes the protein a potentially good target for antiviral drugs directed against the influenza A virus.
Better an... Read More
The TWiVers discuss the growing Ebola virus outbreak in West Africa, and an epidemic of respiratory disease in the US caused by enterovirus D68.
From ocean floors to office desks, bacteria coat nearly every inch of the Earth. Scientists have recently discovered bacteria are present high above the Earth, as well. Ten kilometers up, to be exact, in a region of our atmosphere known as the upper troposphere. In a place where freezing tempera... Read More
Researchers at Harvard and Yale have used some extreme gene-manipulation tools to engineer safety features into designer organisms.
This work goes far beyond traditional genetic engineering, which involves moving a gene from one organism to another. In this case, they're actually rewriting th... Read More
The emergence of community-acquired infections, such as urinary tract infections (UTI), due to strains resistant to common antibiotics are on the rise, according to Rhode Island Hospital researchers. The study is published online in the journal Antimicrobial Resistance and Infection Control.

Bacteria in a drop of water spontaneously form a bi-directional vortex, with bacteria near the center of the drop swimming in the opposite direction of bacteria swimming near the edge. New computer simulations, confirmed by a novel experiment, explain how that vortex comes to be.
