[8] However, in the Protozoa there are examples of hereditary transmission of parasites, e.g., in the case of Babesia (Piroplasma) bovis and Babesia canis in their invertebrate hosts (ticks); in Crithidia melophagia and Crithidia hyalommæ; and in the case of Spirochæta duttoni in its invertebrate host (a tick).
[9] Independently of propagation, many protozoa protect themselves from death by encystment when the water in which they are living dries up; in this condition the wind may carry them over wide tracts of land.
