When the mosquito that carries the malaria parasite (Plasmodium falciparum) bites someone, the parasite must travel to the liver where it undergoes part of its lifecycle before infecting red blood cells and spreading to its next host. Until now, the first step of how the parasite gets to the liver hasn't been clear.
Deadly rat lungworm parasites have found their way into Florida. The parasitic worm relies on snails and rats to complete its life cycle, but don't let this nematode's name fool you. This worm can cause meningitis and death in humans who inadvertently consume snails, frogs, or crustaceans harboring the infective parasite.
Transmitted by a sandfly one-third the size of a mosquito, parasitic Leishmania protozoa are responsible for a flesh-destroying disease that kills an estimated 20,000 people per year.

And around the world, the disease is at the epicenter of a global crisis.
A robust appetite for imported foods is leading to increased disease outbreak in the US. Despite the locovore and slow food movements, America's demand for foreign foods is picking up.

Rising on the world stage, dengue fever is transmitted by mosquitoes — and apparently air travel too.
Citrus greening disease — caused by a bacteria spread by psyllid insects — is threatening to wipe out Florida's citrus crop. Researchers have identified a small protein found in a second bacteria living in the insects that helps bacteria causing citrus greening disease survive and spread. They believe the discovery could result in a spray that could potentially help save the trees from the bacterial invasion.
Mosquitoes are a big problem, and citronella candles are not the solution. There are a lot of mosquito species. The American Mosquito Control Association reports there are more than 3000 mosquito species in the world, and about 200 of those occur in the US.
