a44 VETERINARY NOTES 



Panisset,' while not committing himself to an opinion, thought that the arguments 

 advanced in favour of the protozoal view were not adequate, while Brid<J and N6gre- have 

 applied the complement deviation test, and as a result conclude that the parasite is 

 undouhtedly a yeast. It is possihle that all this confusion is due to more than one kind 

 of parasite being described, but, so far as the Sudan goes, there is every probability that 

 the organism is mycotic. Bitter has cultivated it in Egypt, and finds that its growth is 

 quite characteristic and it is not likely that the Sudan disease differs from the Egyptian. 

 There has been no necessity to carry out research work on the subject here, but tiiis brief 

 review and the accompanying illustration may prove helpful (Plate XVII., fig. 5). 



CocciDiosis IN Cattle 



Montgomery' drew attention to the presence of Coccidiosis in cattle in British East 

 Africa, described the symptoms, and warned observers in Uganda and the Sudan to be 

 on the look-out for this disease which was spreading north from German East Africa. 

 Dr. A. C. Stevenson, when working in these laboratories during the winter 1907-8, 

 discovered a coccidiosis in goats which he describes in this Report {vide page 355). 



Recently I visited Wau in the Balir-El-Ghazal and there examined two herds of sick 

 cattle from the Atwot country in the south. I found one herd suffering from piroplasmosis 

 (infection with P. bigemtnum), but the cattle examined in the other herd showed no 

 parasites and appeared from their history to be recovering from rinderpest. I noticed 

 they presented a scaly condition of the skin and marked anaemia, while some still exhibited 

 nasal discharge. At Kodok on the White Nile I was asked to see some sick cattle, and 

 examined the blood of an ox dying of what certainly appeared to be rinderpest. It 

 presented all the classical symptoms. The blood examined was negative, and I had to 

 leave before the animal died so that no post mortem was made. On revisiting Kodok 

 I found a small herd of sick cattle which were weak, anaemic, and appeared to have a mild 

 attack of rinderpest. Some of the herd had died. I examined the blood of one of these 

 animals, with negative results. Now it so happened that two goats had accompanied me 

 on my journey. They had been put ashore for grazing purposes at several places on the 

 White Nile, and had remained behind at Meshra-El-Rek while one journeyed overland to 

 Wau. A few days out from Khartoum, on the return voyage, one of the goats was noticed 

 to be ill. Its most marked symptom was an aifection of the hide, the skin becoming 

 Goats found scurfy and the hair loose. Dr. Stevenson had noticed this in the goats he examined. It 

 infected j^^^^^ j^gj. appetite, and was getting emaciated. On reaching Khartoum, it was chloroformed 



and examined, as I suspected it was a victim of coccidiosis. This proved to be the case. 

 On killing the companion goat, which was apparently healthy, a similar infection was 

 found to be present. In both cases the small intestine was the portion of gut infected. 



In the light of these facts, therefore, and the timely warning issued by Montgomery, 

 it appears to me that the cattle both at Wau and at Kodok, which appeared to have rinder- 

 pest, may very well have been suffering from coccidiosis. I have drawn the attention 

 of the Civil Secretary of the Sudan Government to the matter, and have suggested that a 

 Veterinary OfiBcer be sent to investigate the disease fully, and if it is found to be coccidiosis,
