As mosquito-borne viral diseases like West Nile fever, dengue fever, and chikungunya fever spread rapidly around the globe, scientists at Virginia Tech are working to understand the mosquito's immune system and how the viral pathogens that cause these diseases are able to overcome it to be transmitted to human and animal hosts. In nearly every part of the world, humans and animals experience high levels of morbidity and mortality after being bitten by mosquitoes infected with viruses. More...

Two teams of Michigan State University researchers — one working at a medieval burial site in Albania, the other at a DNA lab in East Lansing — have shown how modern science can unlock the mysteries of the past. The scientists are the first to confirm the existence of brucellosis, an infectious disease still prevalent today, in ancient skeletal remains. The findings, which appear in the American Journal of Physical Anthropology, suggest brucellosis has been endemic to...

A key mechanism by which a bacterial pathogen causes the deadly tropical disease melioidosis has been discovered by an international team of scientists. The findings are published today in the journal Science and show how a toxin produced by the bacterium Burkholderia pseudomallei kills cells by preventing protein synthesis. The study, led by the University of Sheffield, paves the way for the development of novel therapies to combat the bacterium which infects millions of people across...

Researchers Study Flight Patterns Of Mosquitoes

Experiments by University of California Riverside entomologists demonstrate mosquitoes are attracted first to carbon dioxide, then to skin odors; findings could lead to more effective mosquito traps The carbon dioxide we exhale and the odors our skins emanate serve as crucial cues to female mosquitoes on the hunt for human hosts to bite and spread diseases such as malaria, dengue and yellow fever. Two entomologists at the University of California, Riverside have now performed...

Strains of a bacterium commonly found in fruit flies can prevent the Aedes aegypti mosquito from transmitting the virus that causes dengue fever, researchers have found. Their discovery could lead to a more effective way to control dengue worldwide. North Carolina State University mathematical biologist Dr. Alun Lloyd is part of the Eliminate Dengue program, a research consortium that includes scientists from Australia and the United States. The program aims to stop the Aedes aegypti...

An experimental research carried out in Sant Cugat del Valls and Rubí, coordinated by researchers from UAB, assessed the efficacy of a combination of strategies to reduce the population of tiger mosquitos (Aedes albopictus). The research began in February 2008. The research focused on monitoring eggs found in small experimental traps. Researchers observed that for the first time, the number of eggs diminished after applying the measures. The strategies began with a visit to...

Inhibiting a molecular process cells use to direct proteins to their proper destinations causes more than 90 percent of affected mosquitoes to die within 48 hours of blood feeding, a team of biochemists at the University of Arizona found Mosquitoes die soon after a blood meal if certain protein components are experimentally disrupted, a team of biochemists at the University of Arizona has discovered. The approach could be used as an additional strategy in the worldwide effort to curb...

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 40°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...
