Study reveals classic symbiotic relationship between ants, bacteria
Ants that tend and harvest gardens of fungus have a secret weapon against the parasites that invade their crops: antibiotic-producing bacteria that the insects harbor on their bodies. view more (2006-01-06)
Parasitic plants sniff out hosts
Parasitic plants do not haphazardly flail about looking for a host but sense volatile chemicals produced by other plants and identify potential hosts by their emissions. view more (2006-09-29)
THE BIODIVERSITY OF FALLOW LAND:A FACTOR USEFUL FOR CONTROLLINGPLANT PARASITIC NEMATODES
Fallowing is a common practice for restoring soil fertility and structure in the tropics : it favours improvement in its physicochemical properties and the build-up of stores of organic matter, which are essential for the development of the telluric microfauna and microflora that inhabit soils. Researchers from the Laboratory of Biopedology of IRD... view more... (1999-09-13)
Genetic map offers new tool for malaria research
An international research team announced today the completion of a genome-wide map that charts the genetic variability of the human malaria parasite Plasmodium falciparum. view more (2006-12-11)
Anisakiasis hazard varies depending on the origin of the fish, according to a study
A research team of the University of Granada (Spain) has confirmed a higher presence of the parasite Anisakis spp in anchovies of the Atlantic South East coast and the Mediterranean North West coast, and they insist on freezing or cooking fish before consuming it. view more (2009-11-11)
A Jekyll and Hyde of cytokines: IL-25 both promotes and limits inflammatory diseases
The same signal responsible for promoting the type of immune responses that cause asthma and allergy can also limit the type of inflammation associated with debilitating diseases like inflammatory bowel disease, arthritis and multiple sclerosis. view more (2006-04-10)
Enzyme necessary for DNA synthesis can also erase DNA
In this week's edition of Proceedings of the National Academy of Sciences, PNAS, Uppsala University scientists describe a new mechanism behind an important process that causes a rapid reduction of DNA in the chromosomes of bacteria. view more (2009-06-09)
Logging changed ecological balance for monkeys, damaged health
Twenty-eight years after intense selective logging stopped in the region now known as Uganda's Kibale National Park, the red-tailed guenon (Cercophithecus ascanius) is a primate still in decline. view more (2005-06-15)
Parasite genome sequences offer hope for new drugs and vaccines, Science studies say
Scientists have sequenced and compared the genomes of three of the parasites responsible for sleeping sickness, Chagas disease and leishmaniasis, three devastating diseases of the developing world. view more (2005-07-15)
Bacterial Protein Shows Promise in Treating Intestinal Parasites
Scientists at the University of California, San Diego and Yale University have discovered that a natural protein produced by Bacillus thuringiensis, a bacterium sprayed on crops by organic farmers to reduce insect damage, is highly effective at treating hookworm infections in laboratory animals. view more (2006-09-26)
Hopkins scientists link immune response to 'ghost' parasites and severely congested sinuses
Although it's unclear why it's so, scientists at Johns Hopkins have linked a gene that allows for the chemical breakdown of the tough, protective casing that houses insects and worms to the severe congestion and polyp formation typical of chronic sinusitis. view more (2006-09-07)
Unique immunization method provides insights about protective anti-malaria immune response
In this week's New England Journal of Medicine, scientists in Singapore, The Netherlands and France report that they have developed a novel immunization method that will induce fast and effective protection in humans against the life-threatening malaria parasite, Plasmodium falciparum, which infects 350 to 500 million people world-wide and kills... view more...

Research exposes new target for malaria drugs
The malaria parasite has waged a successful guerrilla war against the human immune system for eons, but a study in this week's Journal of Biological Chemistry has exposed one of the tricks malaria uses to hide from the immune proteins, which may aid in future drug development. view more (2008-08-05)
Genomics and world peace
Developing countries stand to profit most from advances in genome science, write Samuel Broder, Stephen Hoffman and Peter Hotez in this month`s issue of EMBO reports (EMBO reports September, 2002 pp 806-812). They claim that biotechnology coupled with genomics might emerge as the key technology in the 21st century for improving global health and... view more... (2002-08-29)
Potential reinforcing role of earthworm species in plant resistance to parasitic nematodes
Parasitic nematodes of plants are microscopic soil-inhabiting organisms. Although they are present in all crop-growing areas, whether in the tropics or under temperate climes, it is predominantly in the tropical regions that these parasites perpetrate extensive damage and crop-yield losses. Market-garden produce, banana, sugar cane and rice are... view more... (2005-04-15)
HIV and malaria combine to adversely affect pregnant women and their infants
University of Toronto researchers have uncovered the basis by which pregnant women protect themselves against malaria and have also discovered how the HIV virus works to counteract this defence. The research could lead to improved vaccines for pregnant women in malaria-ravished regions. view more (2007-05-30)
Certain combination therapy found more effective for treating malaria in African children
Ugandan children who received the combination therapy of artemether-lumefantrine experienced a lower rate of treatment failure compared to other combination therapies, according to a study in the May 23/30 issue of JAMA, a theme issue on malaria. view more (2007-05-23)
Vaccine new treatment for allergies?
A vaccine against allergies. This may be the eventual result of research at Uppsala university in Sweden. New findings are presented by Anna Ledin in her doctoral dissertation. She vaccinated dogs and rats against their own IgE antibodies, and shows that their allergic symptoms diminished. The type of antibody called IgE is part of the body's... view more... (2004-05-27)
Neglected tropical diseases burden those overseas, but travelers also at risk
Though little known to most Americans, lymphatic filariasis, trachoma, leishmaniasis, onchocerciasis, schistosomiasis and other so-called neglected tropical diseases are responsible for severe health burdens, especially among the world's poorest people. view more (2007-12-26)
Could malaria return to the UK?
Millions of tourists now travel between the UK and countries where malaria is endemic. Given this, entomologists from the University of Durham are to undertake a thorough risk assessment of malaria returning to the UK. Speaking at the Royal Entomological Society’s meeting Entomology 2001: “Insects and disease”, to be held at the... view more... (2001-08-30)
