UCLA researchers awarded $9M contract for study identifiying antibiotic treatment for MRSA
...rgence of the new, potentially more infectious and virulent
strain of S. aureus in the community, referred to as community-associated or CAMRSA, has caused serious outbreaks of disease over the past few years, said Talan, a professor of medicine at the Geffen School of Medicine and chief of emergency medicine...
In case of pandemic flu majority of Americans willing to make major changes in their lives
....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
...c factors that made the 1918 pandemic flu virus so virulent
are described by Adolfo Garca-Sastre, PhD, and Richard J. Whitley, MD, FIDSA. Ten more articles, discussing subjects from disease surveillance to special human populations to animal disease issues, complete the collection. The supplement concludes ...
Foodborne pathogens hard to remove from produce, research is ongoing
...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. It's certainly an unpleasant and potentially fatal illnes...
Live H5N1 avian flu virus vaccines show protection in animal studies
...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. It is particularly dangerous in that it also infects the placenta of pregnant women, with fatal consequences for both her and the foetus. This, combined with the often feeble medical resources of malaria...

Leptospira would be higher in urban than in rural environmental surface waters; and that the concent...

HIV subtype predicts likelihood of early death from AIDS
...anda. Researchers believe that subtype D is more virulent
than subtype A because D has the ability to bind to key receptors on immune cells, allowing subtype D to kill more quickly. 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...

New study says two million Americans harbor drug-resistant superbug
...auses more difficult-to-treat and, sometimes, more virulent
illnesses. MRSA was once primarily a problem in hospitals, but is now a growing problem in communities around the country. Matthew J. Kuehnert, MD, and colleagues collected samples from nearly 10,000 participants in the 2001-2002 National Health and ...
In a crisis, creating DNA vaccine could help save lives, slow spread of 'bird flu'
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?
