Veterinary Notes 



BY 



The Director 



In view of the immense importance of scientific veterinary work in the Sudan, I think 

 it advisable to submit a few observations regarding diseases of animals. These are, of 

 course, entirely from the laboratory standpoint and it is pleasant to record the great 

 assistance, both with notes and specimens, which the officers of the Sudan Veterinary 

 Department have always accorded the laboratories. Some day, I trust we may see one of 

 them on the laboratory Staff, engaged wholly in investigations which are bound to be fruitful 

 both from the scientific and economic aspect. 



Epizootic Lymphangitis of Equines 



Plate XVII., fig. 5 is an illustration of the parasite of epizootic lymphangitis, a common 

 disease of equines in the Sudan, and one at times occasioning heavy losses to Government. 



All kinds of ideas have been advanced regarding its nature since it was claimed as a 

 cryptococcus and named Saccharomi/ces farciminosus by Eivolta. 



Of recent years it has been the subject of many investigations. In 1908, Pricolo^ Recent 

 reviewed the whole subject, pointing out that the majority of observers regarded it as a 

 blastomycete, but that Gasperini had sought to claim it as a protozoon. He also cited the 

 experiments of Sanfelice, Tokishige, Marcone and Baruchello, which all go to prove that 

 it is of a mycotic (fungoid) nature. Sanfelice cultivated the organism and observed 

 the formation of filaments. Plana and Galli-Valerio thought it was a sporozoon and 

 Gasperini,- following Canalis, believed it to be a coccidium and proposed for it the 

 new name, Lyinphoi'poridiinn equi. 



Mori,-^ who, like Gasperini, failed to cultivate it, or to produce lymphangitis in 

 experimental animals by its inoculation, also believed it to be a protozoon. Ducloux, of 

 Tunis, found in the mule a form which he also regarded as protozoal, and, after some study, 

 concluded it to belong to the group Phagocytozoa and named it Leucocytozoon piroplasmoides. 

 Theiler^ finds that in the Transvaal the lymphangitis of equines is due to Saccharomi/ceit 

 farciminosus. 



Thiroux and Teppaz'' agree with Ducloux, and point out the close resemblance of the 

 parasite to Leishmania tropica. The more recent work of Galli-Valerio" led him to adopt 

 the protozoal theory, to support Thiroux and Teppaz, and to name the organism Leishmania 

 farciminosa.
