Seabirds often live in large colonies in very confined spaces. Parasites, such as fleas and ticks, take advantage of this ideal habitat with its rich supply of nutrition. As a result, they can transmit blood parasites like avian malaria to the birds.
Malaria is not only native to the New World, but it has been present long before humans existed and has evolved through birds and monkeys.
For millions of people who live under the constant threat of Leishmania infection, a new discovery by Brazilian scientists may lead to new breakthroughs, preventing these parasites from taking hold in the body or reducing the severity of infections once they occur.
In dengue-endemic areas such as South-East Asia, in contrast to conventional thinking, rural areas rather than cities may bear the highest burden of dengue fever—a viral infection that causes sudden high fever, severe headache, and muscle and joint pains, and can lead to a life-threatening condition, dengue hemorrhagic fever.
ABBOTT PARK, Ill., Aug. 10, 2011 /PRNewswire/ -- Abbott's Ibis Biosciences today introduced a new molecular assay to detect a wide variety of vector-borne microorganisms, including those known to cause Lyme Disease, Rocky Mountain Spotted Fever, Babesiosis, Ehrlichiosis and Anaplasmosis.
Scientists have created spermless mosquitoes in an effort to curb the spread of malaria.
An experimental research carried out in Sant Cugat del VallÃ¨s and RubÃ, coordinated by researchers from UAB, assessed the efficacy of a combination of strategies to reduce the population of tiger mosquitos (Aedes albopictus).
Inhibiting a molecular process cells use to direct proteins to their proper destinations causes more than 90 percent of affected mosquitoes to die within 48 hours of blood feeding, a team of biochemists at the University of Arizona found.
A cheap, common heartworm medication that is already being used to fight other parasites in Africa could also dramatically interrupt transmission of malaria, potentially providing an inexpensive tool to fight a disease that kills almost 800,000 people each year.
Incidence of tick attachments reduced by 93 percent among workers wearing Insect Shield® Repellent Apparel Chapel Hill, NC and Greensboro, NC (PRWEB) July 01, 2011 A pilot study conducted by researchers at The University of North Carolina Gillings School of Global Public Health reported that the incidence of tick attachments was reduced by 93 percent among workers wearing Insect Shield Repellent Apparel.
The Deer Fly (Chrysops spp.), also known as the "yellow fly", is a fly of the family Tabanidae that can be a pest to cattle, horses, and humans. It is often found in damp environments, such as wetlands or forests. It lays clusters of shiny black eggs on the leaves of small plants by water. The aquatic larvae feed on small insects and pupate in the mud at the edge of the water. The Deer Fly is often considered a horse-fly. A distinguishing characteristic is its patterned gold or green eyes....
