Bacteria Quote by Carl Zimmer
““Some ancient eukaryote swallowed a photosynthesizing bacteria and became a sunlight gathering alga. Millions of years later one of these algae was devoured by a second eukaryote. This new host gutted the alga, casting away its nucleus and its mitochondria, keeping only the chloroplast. That thief of a thief was the ancestor or Plasmodium and Toxoplasma. And this Russian-doll sequence of events explains why you can cure malaria with an antibiotic that kills bacteria: because Plasmodium has a former bacterium inside it doing some vital business.””

Endosymbiotic events created complex cells; modern parasites retain ancient bacterial remnants, explaining why antibiotics can affect them.
In simple terms: Cell parts originated from swallowed bacteria; some parasites still hold those bacteria.
