Because the newly formed blood vessels are leaky and tortuous, pericytes are important to protect the fragile vessels [1]. Based on reports that the connective tissue vascular fraction of fat tissue contains stem cells that give rise to pericytes -- cells surrounding small blood vessels -- researchers led by Albert D.
Malaria parasites belong to the genus Plasmodium (phylum Apicomplexa). In humans, malaria is caused by P. falciparum, P. malariae, P. ovale, P. vivax and P. knowlesi. Among those infected, P. falciparum is the most common species identified (~75%) followed by P. vivax (~20%).n humans, malaria is caused by P. falciparum, P. malariae, P. ovale, P. vivax and P. knowlesi.

A single-celled parasite known as a sporozoan causes malaria. This sporozoan belongs to the genus Plasmodium, and the four species that threaten humans are P. falciparum, P. malariae, P. vivax and P. ovale. Of these four, P. falciparum and P. vivax are the most common, and P. falciparum is by far the most dangerous. Image: JIM GATHANY/ CDC. MOSQUITO. This blood-feeding Anopheles gambiae mosquito is one of the leading malaria vectors in the world.
