What are the characteristics of phylum Apicomplexa?
They posses a unique organelle called apicoplast and an apical complex structure involved in penetrating a host's cell. They are unicellular, spore-forming, and exclusively parasites of animals.
How could you distinguish an organelle that originated as a bungled feeding attempt from an organelle that originated as invading parasite?
One organelle will have endosymbionts. While on the other hand, the other organelle will have apicoplast. That is how one can differentiate them.
Can antibiotics kill the protozoa toxoplasma gandii?
Although Toxoplasma is a protozoa, and has eucariotic cell -> some antibiotics (macrolides) can act on it by blocking expression of apicoplast genes (circular DNA), interfering with 50S ribosomal subunit [procariotic ribosome responsible for expression of apicoplast genes]
What are the subphylum of apicomplexa?
The subphylum of Apicomplexa is called Sporozoa. This group includes various parasitic protozoa that possess a unique organelle called an apicoplast, which is involved in various cellular processes. Members of this subphylum often have complex life cycles involving multiple hosts.
Which drug is best known for its use in preventing malaria?
