LIES CYCLE OF TEB MALARIA PARASITE IP MAN AMD 1 QSQUTTO 
Frora the preceding instruction it should be clear in 
everyone*s mind that malaria is caused by a blood destroying para¬ 
site called a Plasmodium, and that this parasite is transmitted by 
a certain kind of mosquito — the Anopheles. The discovery of the 
cause and mode of transmission of malaria paved the way for the 
intricate task of working out the complicated life cycles of both 
the mosouito and the parasites and thus laid the foundation for our 
present day methods of prevention and control. 
The training film, demonstrated how the parasites were 
sucked up through the proboscis or "stinger" of the mosquito into 
the stomach and how the parasites multiplied, passed through the 
stomach wall and finally made their way into the salivary glands. 
This cycle you learned took about 10 days. 
In man another cycle of development takes place. After 
being i.nnoculated by the parasite laden saliva of the mosquito it 
takes about 10 - 14. days for the clinical signs of malaria (chills, 
fever, etc.) to make its appearance. The red blood corpuscles carry 
the parasites through the body and in their sojourn the parasites 
multiply in such great numbers that they finally rupture'the corpus¬ 
cles. This explosive phenomena produces the clinical signs of malaria 
end results in anemia. In the meantime the Plasmodia invade their . 
favorite organs, the liver and spleen, and become so entrenched that 
the drugs we have at present are unable to completely eradicate them. 
This particular resistant form that the parasite takes is why malaria 
is a chronic disease subject to recurrence. Until a new drug or 
substance is discovered capable of penetrating the deepest recesses 
of the body and capable of destroying the resistant form - one can¬ 
not sneak of malaria in terras of "cure". The individual with malaria
