New understanding of parasite cell structures may provide treatments for serious tropical diseases
Don't even think about trying to pronounce it. Although it is found in many organisms including humans, glycosylphosphatidylinositol has remained a mouthful for laymen and a puzzle for scientists. view more (2006-05-10)
Antibody-based therapies effective at controlling malaria
Passive immunization through the development of fully human antibodies specific to Plasmodium falciparum may be effective at controlling the disease, report researchers led by Dr. Richard S. McIntosh from the University of Nottingham in a paper published this week in the open-access journal PLoS Pathogens. view more (2007-05-18)
Researchers discover how malaria parasite disperses from red blood cells
Researchers at the National Institute of Child Health and Human Development have determined the sequence in which the malaria parasite disperses from the red blood cells it infects. view more (2005-09-20)
A new understanding of how cells defend themselves against bacterial pore-forming toxins
Biologists at the EPFL (Ecole Polytechnique Federale de Lausanne) have unveiled a new twist in a metabolic pathway that cells use to defend themselves against toxins made by disease-causing bacteria. view more (2006-09-22)
Research identifies first method for testing, assessing drug treatments for Chagas' disease
Chagas' disease is a tropical parasitic sickness that currently affects more than 16 million people, with a staggering 100 million at risk, largely in the tropical areas of South and Central America. And yet the main drug used to treat the disease is highly toxic and causes serious side effects. view more (2008-04-21)
Scientists lift malaria's cloak of invisibility
The world's deadliest malaria parasite, Plasmodium falciparum, sneaks past the human immune system with the help of a wardrobe of invisibility cloaks. view more (2005-12-29)
Can acne protect against cancer?
Acne is the scourge of teenagers everywhere, but according to an article published in the November issue of the magazine Microbiology Today the bacteria which cause this disease may protect sufferers from other infections and cancer in later life. Dr Anne Eady of the Skin Research Centre at the University of Leeds says, "There may be... view more... (2001-11-01)
New highly active agents against leishmaniasis
Parasitic diseases, especially leishmaniases and trypanosomiases, kill hundreds of thousands of people every year in the world, mainly in the countries of the South. The most severe form of leishmaniosis (kala-azar, the visceral form), induced by Leishmania donovani and L. infantum, affects about 500 000 people per year and proves fatal if no... view more...

Carbohydrate Chemistry Comes of Age
A new national network of chemists and biologists is planning to open up a vital area of chemistry that could have major implications for the drug, food and agrochemical industries. The UK Carbohydrate Chemistry Network, being set up at the University of East Anglia (UEA), will involve scientists from across the country who are trying to... view more... (2001-10-23)
Sleeping sickness finding could lead to earlier diagnosis
Sleeping sickness creates a metabolic 'fingerprint' in the blood and urine, which could enable a new test to be developed to diagnose the disease, according to new research published today in the journal Proceedings of the National Academy of Sciences. view more (2008-04-15)
Disease-impact models may rely on incorrect assumptions
Even when we know how a disease affects individual animals, it is challenging to predict what impact it will have on the whole population, and yet predicting how disease affects a population is a primary concern for wildlife conservation and even public health. view more (2006-04-13)
Strange properties of the tequila plant studied by Mexican student
Tequila is the national drink of Mexico and is also hugely popular worldwide. Now a Mexican student has come to England to study the unusual properties of tequila plants. Postgraduate student Ivan Saldana Oyarzabal, from Guadalajara, which is 50km from the town of Tequila, is studying Agave tequilana and its unusual behaviour at the University of... view more...

New insight in the fight against the Leishmania parasite
Professor Albert Descoteaux's team at Centre INRS - Institut Armand-Frappier has gained a better understanding of how the Leishmania donovani parasite manages to outsmart the human immune system and proliferate with impunity, causing visceral leishmaniasis, a chronic infection that is potentially fatal if left untreated. view more (2009-10-26)
MIT-led team ID's cell mechanics of hallmark malaria protein
During the first 24 hours of invasion by the malaria-inducing parasite Plasmodium falciparum, red blood cells start to lose their ability to deform and squeeze through tiny blood vessels--one of the hallmarks of the deadly disease that infects nearly 400 million people each year. view more (2007-05-29)
Live-in domestics: Mites as maids in tropical rainforest sweat bee nests
Mites not only inhabit the dust bunnies under the bed, they also occupy the nests of tropical sweat bees where they keep fungi in check. view more (2009-04-21)
Extinctions linked to climate change
A new report that links global warming to the recent extinction of dozens of amphibian species in tropical America is more evidence of a large phenomena that may affect broad regions, many animal species and ultimately humans. view more (2006-01-12)
Human pubic lice acquired from gorillas gives evolutionary clues
Humans acquired pubic lice from gorillas several million years ago, but this seemingly seedy connection does not mean that monkey business went on with the great apes, a new University of Florida study finds. view more (2007-03-08)
Arsenic in chicken feed may pose health risks to humans, C&EN reports
Pets may not be the only organisms endangered by some food additives. An arsenic-based additive used in chicken feed may pose health risks to humans who eat meat from chickens that are raised on the feed. view more (2007-04-10)

Blood transfusion-transmitted infections: A global perspective
Thanks to the many blood-safety interventions introduced since 1984, the overall risk for most transfusion-transmitted infections has become exceedingly small. view more (2006-09-28)
