THE DEVELOPMENT OF A PIROPLASMA AND TRYPANO- 

 SOMA OF CATTLE IN ARTIFICIAL CULTURE MEDIA. 



By Erich Martini.^ 

 {From the Biological Laboratory, Bureau of Science.) 



Since January, 1909, I have been on leave of absence in Manila. 

 During this time I have been employed in the Biological Laboratory 

 where I have had the opportunity of making blood examinations in 

 cattle. Among the dozen apparently quite healthy calves placed at my 

 disposal, I found in one the parasite of surra, which disease is not uncom- 

 mon in the Philippines-; in another calf I discovered a species of piro- 

 plasma. This latter, parasite reminded me both of the piroplasma of 

 coast fever^discovered by Eobert Koch(l) in Ehodesia — and of the 

 piroplasma of cattle discovered by Dschunkowsky and Luhs(2) in Cau- 

 casas; it also resembles somewhat the piroplasma described by Miyajima 

 and Shibayama(3) in Japan, and the one which I (4) found in Shantung 

 and in Petschili, China. Hunter (5) in Hongkong has also given a 

 description of a piroplasma of similar morphology; unfortunately he 

 has published no illustrations of this parasite. Recently Schein(6) has 

 made an observation similar to that of Hunter, in Indo-China, his article 

 containing numerous drawings. In many points there are variations 

 between the piroplasma I have found in Manila and the other piroplas- 

 mata mentioned ; however, these variations are probably only of secondary 

 importance. Tlie different forms of the Manila piroplasma are illustrated
