T. licili\ultoniiii (lig. 141) is similar. Numerous flagellates are blood parasites, among them Trypoiosoiiia brucci, which is introduced into horses and cattle in Africa by the tze-tze fly {Glossimi iiiorsilaiis), sometimes deci- mating the herds. Two other species, Tr. ci'ivisii and Tr. cqiiipcrdiim attack horses. Tr. (^aiubiciisc {caslcllaiii) occurs in the blood and cerebrospinal fluid of man in tropical Africa, causing the 'sleeping sickness,' especially fatal to negroes, intermediate host Glossiiia palpalis. Tr. Incisii (fig. 13S) in rat's blood. Since the reproductive stages of Tr. zicmanni show many resemblances to iheSpiroductir, the latter, long regarded as Bacteria, may be llagellates. These extremely dangerous organisms multiply bv longi- ...'V tudinal division (the Bacteria by transverse), have a very motile corkscrew body, prolonged at either end into a flagellum.
