Coccidiosis of cattle in East Africa 
Hv l-isTAiK MOXTCiOMI-RY. 
T'owards the end of 1908 a disease whieh wa.s retj^arded as Rin- 
derpest was found to he spreadinij;' Ifastwards from Lake Xdctoria 
aciajss the cattle-raisinc; districts towards Xairol:)i. At LakeXakuru 
a large Ouarantine camp was formed bv the Veterinary Depart¬ 
ment, and several hiindred animais were kept under observation. 
Stordv (i) there endeavoured to infect b\' inoculation of blood and 
bv contact, four half-bred (English-Afri'can) cattle. The results 
were négative, as were those of the experiments (th.ree in niim- 
ber) subsec|uentlV undertaken at Xairobi. Rinderpest is nol en- 
demie in Ifast Africa, and the use of half-bred animais, whose 
susceptibilité to this disease is maxitnal, clearlv indicated that the 
new disease was not inoculable. l'rom the historv it appeared lo 
hâve travelled Xorthwards from (üerman Ifasl Africa and to hâve 
been carried Ifast b\' .Somalis trading cattle. Wb’thin the first six 
months of 1909 most Ruropeans who owned cattle on the X'akurit 
area of the Highlands suffered more or less. In many cases it was 
not possible to trace contagion to the introdu'ction of sick animais 
or to indirect fomites, and much contoversv ensued as to whe- 
ther or no Gastro-enteritis (as it was christened) was contagions. 
On me arrivai in this countrv in .September 1 proceeded Xorth 
of Mount Kenva, where Ixinderpest was said to be killing of 
many native cattle, and where Eland and Buffalo were reportée! 
to be dving b^' the roadside. In ever\' post-mortem examination 
on Cattle and in several cases dtiring life, ,1 was able to demon- 
strate CTccidia in the faeces or intestinal tract. 
The pathologic<al c'hanges met with in this disease, and the 
SN'mptoms induced, are in pc'rfect at'i'ord with Rinderpest. Stoma-
