![deer, Cervus dama 1j. ^poronts 1 to long by O'75-l g broad. Sporogony unknown. B. ovis (Babes) (=; Ilecmatococcus ovis Babes, Piroplusma ovis Laveran, Ama-bonjjoridittin polifphaffum Bononie). In blood of sheep. Causes disease called “ Carceaz ’’ in Eoumania. Sporogony in Rhipicfij)halus bursa Can and Fanz. B. equi (Laveran) (= Biroplasma cqtii Lav.). In the blood of horses in S. Africa and Madagascar. Sporogony in lihipi- ci'phalus evcrtsi Neum. To the above species are ascribed similar parasites found in the blood of the mule and donkey and, according to Koch, by Kudicke in the zebra. B. canis (Piana and Galli-Falerio) {— Piroplasma bigeminum var. canis Piana and Galli-Val., Biroplasma canis Laveran). Fig. 21Ga.—Sc-hizogonic cycle of Babesia eaiiis. {After Nuttall.) Causes “ malignant jaundice ” in dogs. Spoionts 5 to 6 5 p long by 2‘5 to 3'5/a broad. Sporogony in Ilcemaphysalis leachi Andouin in S. Africa. Bermneentor reticulatus (Fabr.) in Europe. Christophers claims to have worked out the sporo- gony of this Babesia in Rhipicephalus sanguineus (Latrulle). He says the ookinete gives rise to an oocyst which may attain a diameter of 25 p, then it breaks up into sporoblasts which may separate, and in turn give rise to sporozoites. In nymphal ticks the development takes place in the protoplasm of the embryonic tissue cells, which are already beginning to shape the future adult. In adult ticks the ookinete migrates to the ovaries, and infection is transmitted hereditarily. (Figs. 21G, 216a.) B. vesperugina (Dionisi, 1898) (= Achromalicus vesperuginis Dionisi). In the noctule, Vesperugo noctula Schreber. Sporonts 2 to 3 /i long by 0'3 to 1 broad; sexual differentiation marked. Sporogony unknown, possibly in Hcemalastor ves- pcrtilionis. B. rossi Sambon, 1907. Found by Philip II. Bo.ss in monkeys (cercopithecus) at Kikuyu, E. Africa. Pear-shaped s])oronts 2-5 p by P5 p ; double form very rare. Invertebrate host unknown. Other babosiie have been mentioned as occurring in mon- keys and in goats in Africa. In 1902 Wilson and Chowning announced the discovery of a babesia in patients suffering from “Slotted fever” in the Rocky Mountain^, and proposed to name the new parasite Biroplasma hominis. At about the same time, Gotschlich, in Egypt, stated that he had found a babesia in patients suffering from typhus fever. Those findings have not been confirmed. Sambon suggests that blackwatcr fever may be due to a minute babesia. B B*](https://iiif.wellcomecollection.org/image/b24906931_0883.jp2/full/800%2C/0/default.jpg)
