Here’s a riddle: What’s the difference between a tick and a lion? The answer used to be that a tick is a parasite and the lion is a predator. But now those definitions don’t seem as secure as they once did.
They are tiny, ugly, disease-carrying little blood-suckers that most people have never seen or heard of, but a new discovery in a one-of-a-kind fossil shows that “bat flies” have been doing their noxious business with bats for at least 20 million years.
As mosquito-borne viral diseases like West Nile fever, dengue fever, and chikungunya fever spread rapidly around the globe, scientists at Virginia Tech are working to understand the mosquito's immune system and how the viral pathogens that cause these diseases are able to overcome it to be transmitted to human and animal hosts.
Lyme disease is the most commonly reported vector-borne disease in the United States, with the majority of cases occurring in the Northeast.
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.
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....
