. Special pathology and therapeutics of the diseases of domestic animals. Veterinary medicine. 766 Piroplasniosis of Cattle. rod and lancet forms are found rarely, and the presence of more than two parasites in one blood corpuscle is also infre- quent. The cultivation and propagation on artificial media has not yet been successful with a certainty. According to Lignieres and Miyajima they are supposed to multiply in blood- bouillon for a time, ami here, according to the observations of the Japanese investi- gator, forms containing Hagellae similar to the trypanosonies are supposed to appear after 3-4 days; the propagation reaches its height on the lOtli to 14th day; on the day, however, the culture ilieil (it is possible that they represented mixed infections). According to Smith & Kilhorne, as well as Laveran & NicoUe, their propagation results by fission, or schizogony, while according to Theiler's former view, which was also accepted by Koch, the parasites assume, in certain stages of development, rod- and ring-shapes, and then appear similar to the causative factor of African horse fever (Fig. 131). Such forms are usually found in the l)lood of cattle that are immune against Texas fever, and they also appear in the blood of calves, which have lieen infected with the ])lood from such cattle, during or after the second reaction. Recently, however, these forms were described by Theiler as a new variety, (Piroplasma mutans), (see p. 782).. -Fig. 130. Piroplasma higemi- Spherical and pear shapes.
