Veterinary Work at Uganda. 



THE following report by Mr. Stordy, 

 M.ll.C.V.S., on veterinary work in 

 British East Africa and Uganda Protec- 

 torate is published by order : — 



Tsetse Fly Disease (Ngana). 



The red line on the map prefixed 

 shows the extent of the Tsetse Fly belt, 

 a distance of roughly 90 miles. 



The fly is migratory in tendency, so 

 that no well defined line on the map can 

 be drawn, which could safely exclude the 

 possibility of its presence. 



The fly, however, has never been 

 located further inland than Muani (a 

 halting station in the Kiu Hills on the 

 old caravan route). 



In my preliminary report on the 

 causes which rendered the island of 

 Mombasa uninhabitable for horses, I 

 pointed out that an organism, the mor- 

 phology of which was identical with 

 that found in animals suffering from 

 t&etse fly disease, was found in donkeys 

 which had been working for some time 

 on the island. 



Whether the disease caused was Surra 

 or Ngana time would not permit me to 

 judge, but I trust at no very distant 

 date to be able to follow up my inves- 

 tigations at Mombasa. 



It is useless to go into the details of 

 the pathology, etc., of this disease — a 

 disease which has been practically eradi- 

 cated by the advent of the Uganda rail- 

 way, with its excellent service of horse 

 boxes and fly proof gauze windows. 



SoTTTH African House Sickness 



(Oedememycosis). 



This disease, so far as is known, is 

 peculiar to Africa. It affects horses, 

 asses and mules. 



It occurs as a rule in low-lying parts 

 of the country, where vegetation is 

 abundant, and the ground below the 

 undergrowth moist. 



Animals which have suffered from the 

 disease and subsequently recover are 

 spoken of as "salted," and are believed to 

 be protected for the future. 



Symptoms :— Faardziekte Foim.— Tne 

 symptoms in this form only present 

 themselves at the onset of death. 



An apparently healthy animal will 

 siiow grave respiratory disturbances, 

 heaving violently at the tlanks, and 

 within a very short time falling down, 

 ejecting at the moment of death a cloud 

 of foam from the nostrils and mouth. 



This form of the disease has been the 

 most common in Uganda. 



Dikkop Ziekte Form.— In v,h ch the 

 head and neck swell up. 



Blauwtong Form. — In \\\\\ch the swell- 

 ing is confined to the tongue. 



Much yet remains to be learned of 

 the pathologv of horse-sickness, and I 

 sincerelv hope that a laboratory will be 

 e-tal)lished in the East African Pro- 

 tectorate where investigations can be 

 carried out with a view to doing some- 

 thing towards the elucidation of this 

 l)aneful malady. 



The stables built at each camping 

 place have done much to lessen the mor- 

 tiility from this disease. 



Binder I'EST. 

 This disease has existed in the 

 country for the last five or six years. 



My reports, forwarded through Sir 

 Harry Johnston, give full details of the 

 work done by way of prevention and 

 suppression. 



So far no manifestation of this malady 

 has been noted beyond the Gilgil river 

 (10 miles inland from Naivasha), and it 

 is to be hoped that the regulations now 

 in force will prove adequate in keeping 

 the disease within its circumscribed area. 



I may add that bullock transport is 

 now working from Nakuru railway sta- 

 tion inland. 



Contagious Pleuro-Pneumonia. 

 This scourge broke out amongst our 

 transport oxen at Nandi in September, 

 1898. 



Tail inoculation was had recourse to 

 and isolation camps formed. The re- 

 sults of the inoculation were entirely 

 satisfactory, and no renewed manifesta- 

 tion of the disease has since occurred.
