What causes a virus to suddenly begin infecting large numbers of people?
MENLO PARK, Calif., May 5, 2011 /PRNewswire/ -- In parts of the world where dengue fever is common, other viral infections are often misdiagnosed. Such misdiagnosis is a waste not only of time and money.
Researchers have identified 93 seminal fluid proteins and 52 sperm male-derived proteins that include candidates likely to affect the behavior and physiology of female mosquitoes of the species, Aedes aegypti.
A review released Tuesday by a panel of scientific experts casts doubt on FBI evidence that Bruce Ivins, a US Army researcher, committed the deadly anthrax mailings of 2001.
The risk of deadly hantavirus outbreaks in people can be predicted months ahead of time by using satellite images to monitor surges in vegetation that boost mouse populations, a University of Utah study says.
There is a new player in the fight against dengue fever in Malaysia, 6,000 of them actually.
An official said on Tuesday that Malaysia has delayed a landmark field trial to release genetically modified mosquitoes designed to combat dengue fever.
Alexander Raikhel's lab identifies a microRNA molecule that controls blood feeding and egg development in Aedes aegypti females.
CHICAGO, Dec. 2, 2010 /PRNewswire/ -- Advanced Life Sciences Holdings, Inc.
British scientists have created genetically modified sterile mosquitoes in an experiment to kill off others in their species, and researchers are hopeful that early field trials could help to stave off the rapid spread of dengue fever.
Francisella tularensis is a pathogenic species of gram-negative bacteria and the causative agent of tularemia or rabbit fever. It is a facultative intracellular bacterium. It is classified as a Class A agent by the U.S. government due to its ease of spread by aerosol and its high virulence. In 1911 the species was found in ground squirrels in California. There are four subspecies that have been classified. Biovar tularensis is found mostly in North America. Biovar palearctica is found...
Burkholderia pseudomallei is a Gram-negative, bipolar, aerobic, motile rod-shaped bacterium. It causes the disease melioidosis in humans and animals and is also capable of infecting plants. The bacteria can from in a number of artificial environments. Optimal temperature is around 40Â°C in pH-neutral or slightly acidic environments. Most strains can ferment sugars without gas formation. The bacteria produces both exo and endo toxins although the role of these toxins has not been fully...
Yellow fever is an acute viral hemorrhagic disease with a 40 to 50 nm enveloped RNA virus with positive sense of the Flaviviridae family. It is transmitted by the bite of female mosquitoes and is found in tropical and subtropical areas in South America and Africa, but not in Asia. Primates and a few kinds of mosquitoes are the only known hosts. The origin of the disease is most likely Africa. From there it was introduced to South America through the slave trade in the 16th century. There...
Venezuelan equine encephalitis virus is a mosquito-borne viral pathogen that causes Venezuelan equine encephalitis or encephalomyelitis (VEE). It can affect all equine species, such as horses, donkeys, and zebras. Equines may suddenly die or show progressive central nervous system disorders after infection. It is contractible by humans and will usually experience flu-like symptoms when infected. People with a weak immune system can become seriously ill or die. It is transmitted primarily...
Rinderpest (also cattle plague) is an infectious viral disease of cattle, domestic buffalo, and some species of wildlife. It is characterized by fever, oral erosions, diarrhea, lymphoid necrosis, and high mortality. The last confirmed case was in 2001. In 2011 it should be announced that a global eradication of rinderpest was complete. The term comes from the German language meaning cattle-plague. The rinderpest virus is closely related to measles and canine distemper viruses. It is a...
