This organism appears to be the same as that found by Smith and Kilborne, and if proved so by the full life history the organism of Texas fever must have the specific name bovis, while, since hematococcus is the generic name of a phytoflagellate, Starcovici's name babesia must supplant Patton's piroplasma. Fig. 107. mm r^STS:- Stages in the development of Babesia canis. (After Kinosliita.) A^ round discoid parasite in a blood corpuscle; B, ameboid form with long processes; C, a pair of " mature gametes"; D, a mature "female" gamete; E, a mature "male" gamete; F, a budding form in blood corpuscle; G, a group of sixteen young "; Subsequent observers have found babesia in many different animals. R. Koch ('03) was sent by the German Government to investigate a cattle disease which he called East Coast fever, in German East Africa, and the organism causing it was named (piroplasma) Babesia â parvimi by Theiler, in 1904. Babes ('92) discovered a blood parasite in Roumanian sheep which he named Babesia ovis; Plana and Galli Valerio ('95) discovered a similar parasite in the blood of dogs, naming it (piroplasma) Babesia canis; Gugliemi ('99) found a blood parasite in horses, Laveran ('01) naming it (piroplasma) Babesia equi; Fan- tham ('05) discovered one in the blood of rats and called it (piro- plasma) Babesia muris. Similar parasites have been found in monkeys. Please note that these i
