 Malaria   (Site not responding. Last check: 2007-10-10)
The Plasmodium genus of protozoal parasites (mainly P.falciparum, P.vivax, P.ovale, and P.malariae) have a life cycle which is split between a vertebrate host and an insect vector.
The Plasmodium species, with the exception of P.malariae (which may affect the higher primates) are exclusively parasites of man. The mosquito is always the vector, and is always an Anopheline mosquito, although, out of the 380 species of Anopheline mosquito, only 60 can transmit malaria.
The reason that not all mosquitos are vectors for Plasmodium parasites is that refractory mosquitos posses substances toxic to Plasmodium within their cells (7).

 Nikon MicroscopyU: Human Pathology Digital Image Gallery - Plasmodium vivax Infection
In the 1880s, a surgeon with the French military, Alphonse Laveran, identified parasitic protozoa as the cause of malaria, and over the ensuing decades a number of scientists contributed to the identification of the bite of the female Anopheles mosquito as the mode of transmission.
Identification of which Plasmodium species is the cause of specific malarial cases usually is based upon the morphology of the red blood cell stages of the parasite.
Red blood cells infected with Plasmodium vivax are frequently significantly larger than normal cells, swelling to typically one and a half times their size.

 Plasmodium Liver Infection and Immune Response
Model for Plasmodium sporozoite migration in the liver: Migration of Plasmodium sporozoites through hepatocytes in the liver induces exocytosis that results in the exposure of transmembrane proteins, such as TRAP, in the surface of the sporozoite.
Plasmodium infection induces immune suppression that is associated with the inability of infected individuals to prevent malaria re-infections throughout life, increased susceptibility to other infections and reduced response to vaccinations.
We found that Plasmodium infected erythrocytes inhibit the activation of dendritic cells by inhibiting the up-regulation of co-stimulatory molecules, altering their cytokine secretion pattern and inhibiting their ability to activate T cells (Ocaña-Morgner et al., 2003.

Plasmodium falciparum is a protozoan parasite, one of the species of Plasmodium that cause malaria in humans.
Malaria is caused by infection with protozoa of the genus Plasmodium.
The apicomplexan plastid, or apicoplast, is an essential organelle, thought to be involved in the synthesis of lipids and several other compounds, and provides an attractive target for antimalarial drug development, particularly in light of the emergence of parasites resistant to chloroquine and other existing antimalarial agents.

 Malaria: Parasitic Infections: Merck Manual Home Edition
Plasmodium vivax and Plasmodium ovale can remain in the liver in a dormant form that periodically releases mature parasites into the bloodstream, causing recurring attacks of symptoms.
A decrease in the level of sugar (glucose) in the blood can occur in people infected with Plasmodium falciparum and may be severe in people who have a large number of parasites in their blood—particularly if they are treated with the drug quinine.
Malaria caused by Plasmodium vivax, Plasmodium ovale, and Plasmodium malariae tends to be less severe, although these parasites can remain in the blood for long periods, producing fever, chills, headache, poor appetite, fatigue, and a general feeling of illness (malaise).

 Lifecycle of the plasmodium parasite.
Plasmodium falciparum occurs in almost all areas affected by malaria and it is classed in most cases resistant to chloroquine.
Plasmodium vivax infection is predominantly located in South America as well as the Middle East, but is uncommon in sub-Saharan Africa.
If the infection reaches an advanced state the plasmodium start to clog the capillaries that carry blood to the brain, (this is called cerebral anemia (anaemia)) and various other organs of the body.

Plasmodium is Bob Miller (trumpets, flugelhorn, keyboards, sound manipulations) and Jim Thomson (drums, percussion, sound manipulations, and voice).
Initially conceived in Richmond, Virginia in the year 2000 as an improvisational and experimental drum and trumpet duo, Plasmodium has since expanded its music into the realm of clairaudience -- the perception of messages in thought forms from entities who exist in another realm -- after experiencing supranormal hearing during their rehearsals.
Using a dizzying array of drum loops, keyboards, trumpets, diodes, crystals, mirrors, and audio-visual surveillance monitors finetuned to paranormal frequencies, Plasmodium gives the psychic phenomenon known as clairaudience a sound, so to speak, and they paint a "sound-surveillance" portrait of sonic apparitions that they channel in their laboratories.
