SEATTLE, Dec. 18 /PRNewswire/ -- IDRI (Infectious Disease Research Institute) today announced it has received a 3-year, $7 million grant from the Bill & Melinda Gates Foundation to develop new methods of diagnosis and care management for patients in Africa who are infected with Leishmania donovani -- the parasite that causes visceral leishmaniasis (VL) in the region. Visceral leishmaniasis is a serious, potentially lethal, systemic parasitic illness that has caused epidemics in...

Australian scientists say they have filmed an immune cell as it becomes infected by a parasite and followed the infection as it spread throughout the body. Researchers led by Professor Wolfgang Weninger at the Centenary Institute said they used high powered, multi-photon microscopy that allowed real cells to be viewed in real time. Using multi-photon microscopy, we studied dendritic cells in the skin, Weninger said. Under normal conditions we found the cells in the epidermis (top layer) were...

British and Scottish scientists say they've come up with a better way to separate parasites from their host cells, allowing detailed studies of their proteins. The researchers, led by Toni Aebischer of the Institute of Immunology and Infection Research at the University of Edinburgh, said their new method will allow a thorough analysis of proteins involved in parasitic organisms. That, in turn, might be tremendously useful for drug or vaccine development, Aebischer said. Until now, the...

Researchers said on Tuesday it was possible that the mysterious decline in North American bee populations could be due to disease spread to wild bees from commercially bred bees used for pollination in agriculture greenhouses. Scientists have been expressing alarm over the falling numbers of bee populations in recent years in North America. Experts warn the bee disappearance eventually could harm agriculture and the food supply. The recent decline in various bee populations in North America...

Children infected by Chagas disease, endemic in 21 countries in Central and South America, will soon have access to a treatment tailored to their needs. As a result of the new partnership between Lafepe and DNDi, the first pediatric formulation of benznidazole will be made available to patients by the end of 2009. The drug will be sold at cost, with no profit to the institutions involved in its development, and will be available for distribution worldwide. Although benznidazole has been...

MBL, WOODS HOLE, MA -- For years biomedical researchers have known that high density lipoproteins, commonly called HDLs or "good cholesterol," are responsible for protecting humans from certain parasites, but couldn't explain how. Now MBL scientists have discovered that human HDLs work this bug-repelling magic by serving as a platform for the assembly and delivery of two naturally occurring proteins that combine to create a super-toxic antimicrobial. The research, published in the September...

Visceral leishmaniasis, which is the most severe form of that group of diseases, affects 500 000 people in the world each year. It is caused by a protozoan, Leishmania infantum, transmitted by sand fly bites. There is no vaccine for this disease, which can rapidly lead to death if no treatment is given. In the most heavily affected areas, the dog population is hit heavily by infection. It acts as parasite reservoir for humans. Development of a vaccine for dogs could help brake transmission of...

An international group of researchers working in more than 20 laboratories around the globe have determined genetic blueprints for the parasites that cause three deadly insect-borne diseases: African sleeping sickness, leishmaniasis and Chagas disease. The research, funded in part by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, is published in this week's issue of Science. Knowing the full genetic make-up of the three...

A team of international scientists has sequenced the genomes of three species of parasites responsible for causing diseases that kill or cripple millions, primarily in tropical and sub-tropical countries. Howard Hughes Medical Institute (HHMI) scientists who participated in the project say the sequencing of the genomes of the parasitic protozoa that cause Chagas disease, African sleeping sickness, and leishmaniasis, could significantly impact world health. Some of the genes discovered may...

Nearly 20 million people worldwide are infected with a parasitic ailment called Chagas Disease, and nearly a third of those will develop severe heart trouble. Although options for treatment are poor and there are no vaccines, a new study by scientists at the University of Georgia of proteins in the parasite that causes the disease may offer hope. The first-ever global survey of protein expression in the four lifecycle stages of Trypanosoma cruzi, the parasite that causes the disease, could...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
