How the parasite gets its food


, : How the parasite gets its food. Science Washington 276(5315): 1031

In this issue of Science, Kasturi Haldar of Stanford University and colleagues report findings that are helping to explain how Plasmodium, the parasite that causes malaria, imports nutrients from outside the red blood cells it infects. Researchers have suspected for several years that Plasmodium obtains at least some of its nutrients via a complex series of membranous tubules and vesicles that it builds throughout the red blood cell shortly after infecting it. Now, Haldar and colleagues have discovered that a chemical that disrupts the membrane network prevents the parasite from importing essential nutrients such as protein-building amino acids.

Host density can increase infection rates and reduce host fitness as increasing population density enhances the risk of becoming infected either through increased encounter rate or because host condition may decline. Conceivably, potential hosts c...

Food-prey-predator interactions may involve both 'bottom-up' and 'top-down' processes. Conventionally, food-host-parasite interactions have been seen as governed solely from the 'bottom-up', i.e. well-fed hosts can...
