the infective stage of malarial parasite plasmodium that enters human body is
Plasmodium The life cycle of Plasmodium involves several distinct stages in the insect and vertebrate hosts. In infected mosquitoes, parasites in the salivary gland are called sporozoites. When the mosquito bites a vertebrate host, sporozoites are injected into the host with the saliva. From there, the sporozoites enter the bloodstream and are transported to the liver, where they invade and replicate within hepatocytes. At this point, some species of Plasmodium can form a long-lived dormant stage called a hypnozoite which can remain in the liver for many years.[2] The parasites that emerge from infected hepatocytes are called merozoites, and these return to the blood to infect red blood cells.
Infection Infection is the invasion of an organism's body tissues by disease-causing agents, their multiplication, and the reaction of host tissues to the infectious agents and the toxins they produce.[1][2] Infectious disease, also known as transmissible disease or communicable disease, is illness resulting from an infection.
