Scientists have taken an important step towards new malaria treatments by identifying a way to stop malaria parasites from multiplying. In a study published in Nature Chemistry, they show that blocking the activity of an enzyme called NMT in the most common malaria parasite prevents mice from showing symptoms and extends their lifespan. The team are working to design molecules that target NMT more potently, and hope to start clinical trials of potential treatments within four years. A...

Study Explores Evolution Of Bacteria That Can Be Used To Fight Dengue
2013-12-16 12:43:03

Instituto Gulbenkian de Ciencia Wolbachia, a symbiont that resides naturally up to 70% of all insect species, are probably the most prevalent infectious bacteria on Earth. In 2008 Luis Teixeira, now a principal investigator at the Instituto Gulbenkian de Ciência (IGC, Portugal), and other scientists have discovered that Wolbachia can protect their hosts against viral infections. Since then, several studies have been made to further investigate the interactions between Wolbachia and...

Breakdengue.org is crowdsourcing dengue prevention with a $10,000 prize. (PRWEB) December 13, 2013 Breakdengue.org announced a prize of $10,000.00 USD to anyone with a dengue-combatting initiative. We’re crowdsourcing existing initiatives that may come from anywhere in the world to serve as models for other dengue-affected communities around India. Philip Weiss made the announcement public on behalf of Breakdengue.org during his speech at TEDxGateway in Mumbai. Breakdengue.org is...

Expected Effects Of Climate Change May Lead To Decline Of Snail Fever In Africa
2013-12-13 13:19:49

University of Copenhagen The dangerous parasite Schistosoma mansoni that causes snail fever in humans could become significantly less common in the future a new international study led by researchers from the University of Copenhagen predicts. The results are surprising because they contradict the general assumption that climate change leads to greater geographical spread of diseases. The explanation is that the parasite’s host snails stand to lose suitable habitat due to climate change....

Despite gains, recent financial shortfalls and delays in the delivery of commodities have slowed progress, demonstrating the fragility of past success, according to findings of the World Health Organization’s World Malaria Report 2013. New York, NY (PRWEB) December 11, 2013 The World Health Organization’s World Malaria Report 2013, released today, notes continued progress to significantly reduce malaria cases and deaths. But the report also documents that financial shortfalls in 2011...

Mini-microscope For Low-cost Diagnostics Created From Stripped Mobile Phone Camera
2013-12-06 12:34:40

University of Helsinki Microscopy, being relatively easy to perform at low cost, is the universal diagnostic method for detection of most globally important parasitic infections. Methods developed in well-equipped laboratories are, however, difficult to maintain at the basic levels of the health care system due to lack of adequately trained personnel and resources. Researchers at the Institute for Molecular Medicine Finland, FIMM, University of Helsinki and Karolinska Institutet,...

How Mosquitoes Smell Us
2013-12-05 14:31:24

Brett Smith for redOrbit.com - Your Universe Online Many a pleasant summer’s evening has been ruined by the onset of swarms of mosquitoes, and studies have shown that the flying pests are drawn to both the carbon dioxide we exhale and the scent of our skin. A new study, published in the journal Cell, has found that mosquitoes actually use the same olfactory mechanism to detect both carbon dioxide and skin odors. "It was a real surprise when we found that the mosquito's CO2 receptor...

An analysis of patients from across the malaria endemic world suggests that a key antimalarial treatment could be improved by better dosing in young children Antimalarial drug resistance has hampered malaria control programs for almost 60 years. A key factor in combatting this threat is to ensure that all antimalarial drugs are deployed in a way that ensures that the maximum number of patients are completely cured. A study published this week in PLOS Medicine explores this issue 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...
