Innovative Approach Could Ultimately End Sleeping Sickness Disease
2013-10-03 12:29:37

Oregon State University A tag team of two bacteria, one of them genetically modified, has a good chance to reduce or even eliminate the deadly disease African trypanosomiasis, or sleeping sickness, researchers at Oregon State University conclude in a recent mathematical modeling study. African trypanosomiasis, caused by a parasite carried by the tsetse fly, infects 30,000 people in sub-Saharan Africa each year and is almost always fatal without treatment. In a 2008 epidemic, 48,000...

[ Watch the Video: UC Riverside Research Team Identifies DEET Receptors ] redOrbit Staff & Wire Reports - Your Universe Online In research that could lead to the development of a safer alternative to the DEET, scientists from the University of California, Riverside have discovered the olfactory receptors used by insects to sense the repellant. While experts have long known that bugs are repelled by DEET (also known as N,N-diethyl-m-toluamide), UC-Riverside associate professor of...

Pretravel consultations and preventive medications save money for payers and most travelers Not only do U.S. travelers to West Africa who consult health providers before they leave and take prescribed preventive medications substantially reduce their risk of contracting malaria, they also reduce costs to their health insurance providers and, in most cases, to themselves. In a report that has been published online in Clinical Infectious Disease, researchers from the U.S. Centers for Disease...

Recurrent episodes of malaria cause chronic inflammation in blood vessels that might predispose to future infections and may increase susceptibility to cardiovascular disease, a Wellcome Trust study in Malawian children finds. The findings could explain the indirect burden of malaria on childhood deaths in areas where the disease is highly prevalent and children experience multiple clinical episodes of malaria in a year. Malaria is caused by infection with a parasite that starts by...

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...
