Scientists across the United States say they cannot obtain samples of Ebola, complicating efforts to understand how the virus is mutating and develop new drugs, vaccines and diagnostics.
The problems reflect growing caution by regulators and transport companies about handling Ebola as well as... Read More
It is possible to distinguish between different hemorrhagic fevers, including Marburg (Ebola cousin) and Lassa before the person becomes symptomatic, new research has found. This study will allow for the development of better diagnostics, especially during the early stages of disease, when treat... Read More
By changing the direction of a magnetic field, so-called magneto-tactic bacteria are able to make a full U-turn. They can be taught line dancing in this way, inside the tiny micro channels of a lab on a chip. Magnetically steered objects will be capable of delivering medication, for example. Sci... Read More
I came across this paper and thought it sounded interesting for a discussion on TWiP:
Colonisation resistance in the sand fly gut: Leishmania protects Lutzomyia longipalpis from bacterial infection
Non-sterile lab reagents and DNA extraction kits add their own assortment of DNA to microbiome samples.
In this age of cheap DNA technology, scientists are sequencing every sample they can get their hands on. They've ID'd the microbes in mosquito guts, coral mucus and frog skin; in polar ice;... Read More

Recent breakthroughs may pave the way for vaccines and new drugs for those infected by parasitic helminths. These flatworms, including tapeworms that cause hydatid diseases and neurocysticercosis, liver flukes, and blood flukes (schistosomes), infect more than 300 million people and cause approx...

For decades, honeybees have been battling a deadly disease that kills off their babies (larvae) and leads to hive collapse. It’s called American Foulbrood and its effects are so devastating and infectious, it often requires infected hives to be burned to the ground.
Treating Foulbrood is comp... Read More
Dengue virus infects hundreds of millions of people living in tropical countries every year. Transmitted via mosquito bites, the virus typically causes fever, but may also lead to potentially fatal organ failure. The development of mouse models of dengue virus infection could hasten an effective... Read More
Ebola GP protein covers the virus' surface and is shed from infected cells during infection. Shed GP can trigger massive dysregulation of the immune response and affect the permeability of blood vessels.

Behind the hellish Ebola epidemic ravaging West Africa lies an agent that fittingly embodies the mad contradictions of a nightmare. It is alive yet dead, simple yet complex, mindless yet prophetic, seemingly able to anticipate our every move.
For scientists who study the evolution and behavio... Read More
Scientists hope to unlock the secrets of millions of marine microbes from waters as far apart as Sydney’s Botany Bay and the Amazon River in Brazil, with the help of an international team of volunteers sharing their spare computer capacity to create a research “supercomputer”.
The project, co... Read More
The human immunodeficiency virus (HIV) can insert itself at different locations in the DNA of its human host – and this specific integration site determines how quickly the disease progresses, report researchers at KU Leuven’s Laboratory for Molecular Virology and Gene Therapy. Their study was p... Read More
Vincent Racaniello, who studies viruses at Columbia University, says Ebola has recently become his obsession.
"I find myself reading incessantly about Ebola when I should be doing other things," says Racaniello, host of the online show This Week in Virology, which has devoted several recent p... Read More
The digital health revolution is still stuck.
Tech giants are jumping into the fray with fitness offerings like Apple Health and Google Fit, but there’s still not much in the way of, well, actual medicine. The Fitbits and Jawbones of the world measure users’ steps and heart rate, but they don... Read More
On the left is test isolate and on right side is positive control. Imipenem MIC by etest method was 0.75 ug/ml. How to interpret this modified hodge test; positive or negative? Read More
The virus spreading in Guinea, Liberia and Sierra Leone has led to food shortages and neglect of other devastating tropical illnesses.
When Ebola came to Dorcas's home on the outskirts of Freetown in Sierra Leone, the virus spared no one. Her mother brought it home from the clinic where she w... Read More
A genomic analysis has been carried out of Legionella pneumophila strains of 13 legionellosis outbreaks produced in Alcoy during the period from 1999 to 2010. Legionella pneumophila is a strictly environmental pathogen, an opportunistic bacterium that inhabits aquatic and soil environments, spre... Read More
