....doc Pandemic flu is a term used to describe a virulent human flu that causes a global outbreak, or pandemic, of serious illness. Because there is little natural immunity, the disease can spread easily from person to person. Currently, there is no pandemic flu, but health officials are concerned that the ...Latest influenza science and recommendations presented in new release

...li are pathogenic, and E. coli 0157:H7 is a really virulent strain. In most cases, it causes bloody diarrhea and abdominal pain, and in a small percentage of victims, it colonizes the intestinal tract and produces a toxin that can cause kidney failure.

...ccines by combining modified proteins derived from virulent H5N1 flu viruses with proteins from an artificially weakened (attenuated) flu strain. The virulent H5N1 viruses were isolated from human cases in Hong Kong in 1997 and 2003, and Vietnam in 2004. The ...New findings could lead to vaccine for severe malaria
...smodium falciparium is the name of by far the most virulent of the four malaria parasites that infect man.

Additional blood analysis showed that with subtype A, the virus bound only to one kind of receptor, CCR5, to infect the cell....Scientists develop potential pandemic influenza vaccine in mice
...would be problematic since H5N1 viruses are highly virulent in poultry. An egg-based vaccine would also not be useful for stockpiling, as it would not be able to protect against different strains of the virus. Therefore, alternative vaccine-manufacturing strategies are needed. Suryaprakash Sambhara (The Cent...Mice studies illustrate potential of chimp/human antibodies to protect against smallpox

Researchers scrambling to combat a virulent form of bird flu that could mutate into a form easily spread among humans should consider developing vaccines based on DNA, according to British biochemical engineers. DNA vaccines, they say, can be produced more rapidly than conventional vaccines an...Have researchers found a biomarker to signal a more agressive form of prostate cancer?
