Handbook of medical entomology . rnEurope. In this in-stance, also, the diseaseis transmitted by heredity to the ticks of the second the larval, or seed ticks, from an infected female are notcapable of con^eying the disease, but only the m^mphs and more complicated is the condition in the case of Babesia ovis ofsheep, which Motas has shown can be conveyed solely by the adult,sexually mat lire ticks of the second generation. In Babesis canis, Christopher (1907) observed developmentalstages in the tick. He found in the stomach of adult ticks, largemotile club-shaped bodies which he considered as ookinetes. Thesebodies pass to the ovaries of the tick and enter the eggs where theybecome globular in form and probably represent an oocyst. Thisbreaks up into a number of sporoblasts which enter the tissues ofthe developing tick and give rise to numerous sporozoites, whichcollect in the salivary glands and thence are transferred to thevertebrate host. A number of other species of Babesia are kno^um.
