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...

Guest edited by Brandeis professor Donald Shepard, it contains 7 original studies co-authored by Brandeis researchers The ten studies in this special issue document the substantial and growing burden of dengue in the Americas, Africa and Asia, and the burden of a chikungunya outbreak in India. Luiz Tadeu Moraes Figuedo's paper on dengue in Brazil confirms the country's worsening trend; from 1999-2009, where cases rose at 6.2% per year and dengue deaths at 12.0% per year. Carmen Perez and...

Dengue virus circulating between monkeys and mosquitoes could emerge to cause human outbreaks More than a thousand years ago, somewhere in Southeast Asia, a fateful meeting occurred between a mosquito-borne virus that infected mainly monkeys and a large, susceptible group of humans. The result: the world's first outbreak of dengue fever. Today, dengue virus "” which can produce high fever, excruciating joint pain and even death "” has spread throughout tropical Asia, Africa and...

Rinderpest is gone! A cattle disease that has caused millions of people to die of starvation for hundreds of centuries has been declared eradicated from the world, according to world animal health body OIE. "Today we witness a historical event as rinderpest is the first animal disease ever to be eradicated by humankind," OIE Director General Bernard Vallat said at the organization's annual gathering. The Office International des Epizooties (OIE), the World Organization for Animal Health,...

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...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
