Malaria parasite lifecycle, germ theory, and related notes

Flashcards covering malaria parasite lifecycle, germ theory, Koch's anthrax experiment, and historical beliefs about sneezing.

Which eukaryotic parasite infects the liver first and then red blood cells, growing intracellularly while feeding on the contents of red blood cells?

Plasmodium (malaria parasite); life cycle includes hepatic (liver) stage followed by erythrocytic (red blood cell) stage.

What theory states that disease is caused by microorganisms rather than supernatural possession?

Germ theory of disease.

In Koch's experiments illustrating germ theory, which organism was used to demonstrate that a microbe could cause disease?

Bacillus anthracis (the bacterium that causes anthrax).

According to the notes, what belief about sneezing is contrasted with germ theory, as reflected in the origin of saying 'bless you'?

A belief that sneezing could be associated with possession by spirits or demons; the phrase 'bless you' arose in that context.
