A protein produced by mast cells in the immune system may predict which people infected with dengue virus will develop life-threatening complications, according to researchers at Duke Medicine and Duke-National University of Singapore (Duke-NUS). Their study also found that in experiments in mice, a class of drugs commonly used to treat asthma by targeting the mast cells could help treat vascular symptoms associated with dengue infections. The findings were published in the online journal...

With the help of a warning system which measures the risk of dengue incidence using precipitation and air temperature, it is possible to forecast the outbreak of dengue fever up to 16 weeks in advance. This is what Yien Ling Hii concludes in the dissertation she is defending at Umeå University on 3 May. Dengue fever is an infectious disease caused by virus and transmitted to persons by mosquitoes. A person contracted dengue fever usually shows symptoms including sudden spike of...

A new article in The Journal of Parasitology features a study on schistosomiasis vaccine research. The researchers hypothesized that attacking ESP-induced immune responses would lead to almost total elimination of the parasite. Lawrence, KS (PRWEB) April 25, 2013 Nearly 800 million people, mostly children, are at risk for schistosomiasis, a widespread parasitic disease found in more than 75 developing countries. Although drug treatment is effective, it does not prevent reinfection. Research...

Researchers have discovered that rising temperature induces key changes in the dengue virus when it enters its human host, and the findings represent a new approach for designing vaccines against the aggressive mosquito-borne pathogen. The researchers found that the dengue virus particles swell slightly and take on a bumpy appearance when heated to human body temperature, exposing "epitopes," or regions where antibodies could attach to neutralize the virus. The discovery is significant...

Potential weakness identified in make-up of these deadly agents can immediately yield a sensitive test By screening a library of a billion llama antibodies on live Ebola viruses in the Texas Biomedical Research Institute's highest biocontainment laboratory, scientists in San Antonio have identified a potential weakness in the make-up of these deadly agents that can immediately yield a sensitive test. "Detecting single viral protein components can be challenging, especially at very low...

redOrbit Staff & Wire Reports - Your Universe Online Nearly 400 million people are infected with dengue fever each year, meaning that the world´s fastest-spreading tropical illness is affecting three times more people than the World Health Organization (WHO) had previously estimated. Following several years of research, experts from the University of Oxford and the Wellcome Trust revealed those statistics, as well as a detailed map of regions affected by the mosquito-borne...

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...

West Nile virus (WNV) is a virus of the family Flaviviridae. It is part of the Japanese encephalitis antigenic complex of viruses and is found in both tropical and temperate regions. It primarily infects birds but can infect humans, horses, dogs, cats, bats, and other mammals. Humans are generally infected through the bites of mosquitoes and about 90% of West Nile Virus infections are without symptoms. The virion is 45-60 nm and covered with a relatively smooth protein surface. It is...

Marburg virus, or Marburg, is the standard name for the genus of viruses Marburgvirus which contains the species, Lake Victoria Marburgvirus. It causes Marburg Hemorrhagic Fever (MHF) which originated with primates. It originated in Africa and can infect humans and primates. It is in the same taxonomic family as Ebola and both are identical structurally although they elicit different antibodies. It was named after the location of the first outbreak in Marburg, Germany in 1967. The...

Lassa fever, first described in 1969 in Lassa, is an acute viral hemorrhagic fever. Clinical cases were known a decade before this but were not associated with this viral pathogen. It is endemic in West African countries and causes approximately 5,000 deaths. The Natal Multimammate Mouse is the primary animal host. The rodent is a source of protein but the virus is usually transmitted by the contact with the feces and urine of animals accessing grain stores in residences. The lassa virus...

Dengue fever and dengue hemorrhagic fever (DHF), caused by the dengue virus, is among the spectrum of acute febrile tropical disease and is transmitted by mosquitoes. Occurring mainly in the tropics it can be life threatening and is caused by four closely related virus stereotypes of the genus Flavivirus. It was identified and named in 1779. It has a nickname of "breakbone fever" due to it causing sever generalized bodyache. It tends to be more prevalent in the urban districts of its range...
