This document provides information about Plasmodium, the protozoan parasite that causes malaria. It discusses the key topics of the morphology, life cycle, transmission, pathogenesis and clinical features, diagnosis, treatment and prevention of malaria. Some important points covered are that Plasmodium has a life cycle that involves both humans and female Anopheles mosquitoes as hosts, being transmitted via the mosquito's bite. It causes disease by infecting and destroying red blood cells. The four main species that infect humans are P. vivax, P. falciparum, P. malariae, and P. ovale, with P. vivax and P. falciparum being most common in India.

3. ✧ In 1880,CHARLES LAVERAN discovered the
malarial parasite.
✧ The life cycle was described by A. BIGNAMI ,
B.GRASS , G. BASTIANELLI in 1898.
✧ RONALD ROSS in India demonstrated that
mosquitoes of Anopheles species are vectors of
malarial parasites . In 1902 , for this discovery
he was awarded Nobel prize.
✧ TRAGER and JENSEN were first to culture
malarial parasite in vitro in 1976 .

✧ Merozoites
✧ Gametocyte
✧ :Female gametocyte(Macro - gametocyte)
✧ :Male gametocyte ( Micro - gametocyte)

11. MODE OF INFECTION
✧Bite of infected mosquito (FEMALE
ANOPHELES MOSQUITO)

12. CHARACTERISTICS OF LIFE CYCLE :
✧ Definitive host Female Anopheles Mosquito
✧ Intermediate host Man
✧ Infective form Sporozoites
✧ Portal of entry Skin
✧ Mode of transmission Bite of an infected Mosquito
✧ Site of localization First in liver cells and then in RBC's

13. ANOPHELES VECTOR

14. LIFE CYCLE
✧ The malarial parasites pass their life cycle in
TWO HOSTS :
✧ 1. MAN [ INTERMEDIATE HOST)
✧ 2. FEMALE ANOPHELES MOSQUITO ( DEFINITIVE
HOST )
