Early diagnosis and treatment with antimalarial drugs (ACTs–artemisinin based combination treatments) has been linked to a reduction in malaria in the migrant population living on the Thai-Myanmar border, despite evidence of increasing resistance to ACTs in this location, according to a study by international researchers published in this week's PLOS Medicine. These findings are important as this study suggests that alternative treatments are urgently needed to replace the failing...

LA JOLLA, Calif., Feb. 27, 2013 /PRNewswire-USNewswire/ -- Scientists at The Scripps Research Institute (TSRI) have found a telltale molecular marker for Onchocerciasis or "river blindness," a parasitic infection that affects tens of millions of people in Africa, Latin America and other tropical regions. The newly discovered biomarker, detectable in patients' urine, is secreted by Onchocerca volvulus worms during an active infection. The biomarker could form the basis of a portable,...

The powerful venom of the saw-scaled viper Echis carinatus contains both anticoagulants and coagulants finds a study published in the launch edition of BioMed Central's open access journal Journal of Venomous Animals and Toxins including Tropical Diseases (JVATiTD). These may be a source of potent drugs to treat human disease. The saw-scaled viper family Echis, responsible for most snake attacks on humans, are recognizable by the 'sizzling' noise they make, produced by rubbing together...

Mosquitoes Become Less Repelled By DEET After First Exposure
2013-02-21 15:11:59

Brett Smith for redOrbit.com - Your Universe Online The insect repellant DEET has been widely used to keep mosquitoes away and has been invaluable in countries affected by outbreaks of disease such as malaria and dengue fever, both transmitted by the annoying pest. However, a new report in the open-access journal PLoS ONE finds that mosquitoes are less repelled by DEET after an initial exposure. According to the team of U.K. researchers who conducted the study, mosquitoes will ignore...

New research has revealed that immature malaria parasites are more resistant to treatment with key antimalarial drugs than older parasites, a finding that could lead to more effective treatments for a disease that kills one person every minute and is developing resistance to drugs at an alarming rate. University of Melbourne researchers have shown for the first time that malaria parasites (Plasmodium falciparum)in the early stages of development are more than 100 times less sensitive to...

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...

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...
