While genetically modified plants have already been introduced into the wild on a large scale in some parts of the world, the release of genetically modified animals is still at a relatively early stage…
The U.S. Food and Drug Administration approved the first test for use as an additional, more specific test on human serum or plasma specimens found to be positive for antibodies to Trypanosoma cruzi (T. cruzi). T. cruzi causes Chagas disease, a serious and potentially fatal parasitic infection. The test, called the ABBOTT ESA Chagas [Trypanosoma cruzi (E…
A team of New York University biologists has uncovered a previously unknown role for a set of cells within the female reproductive tract of fruit flies that affects the functioning of sperm and hence fertility…
One mystery resolved on cholera by examination of four major river basins - including the Ganges, Brahmaputra, Meghna, Congo, Amazon and Orinoco in South America - finds when water flow rose, nutrients in the water were associated with increase in cholera cases Published on August 3rd in the American Journal of Tropical Medicine and Hygiene - A new study revealed, an inves…
An examination of the world’s largest river basins found nutrient-rich and powerful river discharges led to spikes in the blooms of plankton associated with cholera outbreaks…
With recent deadly cholera outbreaks in Haiti and Cameroon providing the latest indication of a menacingly resurgent disease, scientists have discovered rain and temperature fluctuations in at-risk areas could predict epidemics months in advance, according to a new study published today in the June 2011 issue of the American Journal of Tropical Medicine and Hygiene…
Mummies from along the Nile are revealing how age-old irrigation techniques may have boosted the plague of schistosomiasis, a water-borne parasitic disease that infects an estimated 200 million people today…
The malaria parasite has gradually developed resistance to the most commonly used medicines. To make matters worse, several mosquito species that host and transmit the parasite have become resistant to insecticides, making it difficult to eliminate them from populated areas…
A group of chemical compounds used by a species of tropical seaweed to ward off fungus attacks may have promising antimalarial properties for humans. The compounds are part of a unique chemical signaling system that seaweeds use to battle enemies and that may provide a wealth of potential new pharmaceutical compounds…
