[Piroplasmosis transmission in mammals. Epidemiological and prophylactic consequences]

The author analyses the nosological complex "piroplasmosis" and emphasizes the differences between the two sub-orders and families of "piroplasms". He studies the life-cycle of these parasites in mammals and in their vectors, acari belonging to the super-family Ixodoidea. He lays out the mechanisms of piroplasmosis transmission to animals and, sometimes, to man and draws from these data the epidemiological features and means of control.
