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...

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...

Researchers probing genetics of chikungunya virus identify tiny changes separating epidemic African strain and tamer Asian variety What causes a virus to suddenly begin infecting large numbers of people? Scientists have long known that the process they call "viral emergence" involves a wide variety of factors. Some are changes in the environment, either generated by natural causes or human activity. Others are internal, arising from accidental changes "” mutations "”in the virus'...

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. It can be especially problematic for sufferers of another mosquito-borne viral infection called chikungunya--its high fever, joint pain that can last for years, and intense headache symptoms mimic the clinical profile of dengue. Recovery from the acute phase of the infection can take from...

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...

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...
