This parasite interacts with many host proteins and modifies the expression of many more genes creating an interactome with almost 3000 links. In addition it exchanges substrates and metabolites with the host, modifying many biochemical parameters. T.Gondii disrupts multiple signalling network... Read More
An interesting presentation given by Yuri Gorby, an electromicrobiologist at the J. Craig Venter Institute in San Diego, at CalIT2 at UCSD on electronmicrobiology. Here's part of the description from SciVee.tv:
Respiratory microorganisms capture energy for growth and maintenance as they trans... Read More
A new drug acts as a roadblock for malaria, curing mice of established infection, according to a study in The Journal of Experimental Medicine. Treatment was not associated with obvious side effects, suggesting that the drug may also be safe and effective in humans. Read More
In this blog entry, I explore how students can use their creativity to learn microbiology in innovative and often artistic ways. It makes learning more personal! Read More
Abstract - Bacterial communities in the airways of cystic fibrosis (CF) patients are, as in other ecological niches, influenced by autogenic and allogenic factors. However, our understanding of microbial colonization in younger versus older CF airways and the association with pulmonary function ... Read More
The TWiV team consults an epidemiologist to forecast the future scope of the Ebola virus epidemic in West Africa.
When you purchase chicken eggs at the market, they usually have white or brown shells. But some breeds of chicken produce blue or green eggs. The blue color is caused by insertion of a retrovirus into the chicken genome, which activates a gene involved in the production of blue eggs. Read More

Although Avery, MacLeod, and McCarty showed in 1944 that nucleic acid was both necessary and sufficient for the transfer of bacterial genetic traits, protein was still suspected to be a critical component of viral heredity. Alfred Hershey and Martha Chase showed that this hypothesis was incorrec... Read More
The New York Times has published a nice FAQ ,if you will, about H1N1 and what the general public should keep in mind in terms of worry, protection and symptoms. The article also talks about what public health response is feasible and should be expected. Read More

I did a study of hand washing and hand sanitizer. Is anyone on the list willing to help me identify what grew from my unwashed and even washed hands? I attach three photos representing the yellow, white and orange growths found after several days on agar plates. Thank you so much in advance. Read More
In observation of World Malaria Day this April 25, 2009 Scientific American has published a great online resource for people interested in malaria. "The international community has just two years to meet the United Nations's 2010 goal of providing protection and treatment to every person threate... Read More
Dear Vincent and Dickson,
Listening to TWiP on cyclosporiasis. Because I am all too aware of the possible contamination of many crops as a former public health nurse who worked in epidemiology for my state (Florida), I always wash my fruits and v... Read More
The Sabin infectious, attenuated poliovirus vaccines are known to cause vaccine-associated paralysis in a small number of recipients. In contrast, the Salk inactivated vaccine does not cause poliomyelitis. Why are the Sabin vaccines still used globally? The answer to this question requires a bri... Read More
Chimpanzees from African sanctuaries carry drug-resistant, human-associated strains of the bacteria Staphlyococcus aureus, a pathogen that the infected chimpanzees could spread to endangered wild ape populations if they were reintroduced to their natural habitat, a new study shows.
The study ... Read More
