SHEEPPOX IN GOAT. VARIOLA CAPRINA. 



The goat can be successfully inoculated from the sheep, the 

 resulting vesicles being smaller and less prominent, and the dis- 

 ease assuming a milder type. It is alleged to pass naturally 

 from sheep to goat, and from goat to sheep, as well as from goat 

 to goat but, on the whole, it is a rare disease and goats have 

 been known to live in flocks of sheep attacked with sheeppox, 

 without themselves contracting the disease. The malady seems 

 to be of little account to the goat, yet in sheep countries, the in- 

 terests of flockmasters would demand that it should be stamped 

 out as vigorously as the same disease in sheep. 



GOATPOX ; VARIOLA CAPRINA. 



In Persia according to Bruce goats suffer from a form of 

 variola, having larger vesicles, umbilicated and approximating 

 to, if not identical with cowpox. In Algiers there is found a 

 goatpox from which sheep are alleged to be immune (Nocard, 

 Peuch, Bremond, Galtier) so that further observations are 

 wanted to put the different forms of variola of the goat in their 

 proper places. In a country where sheeppox is constantly 

 present, there is of course the possible source of fallacy of ex- 

 perimenting with animals that have already had the disease, 

 therefore it would be expedient to put all forms of goat variola 

 under police control. 



SWINEPOX. VARIOLA SUILLA. 



Variola appears to be rather more frequent in swine than in 

 goats. Ficanus as quoted by Joubert saw it in 1567, contracted 

 it was supposed from smallpox patients. It was noted by Rama- 

 zini in 1690, by Stegman in 1697, and later by Gerlach and others. 

 In 189 1 517 cases were reported in Hungary. It is said to be 

 derived from man by the use of bed straw for litter and from 

 sheep by occupying the same stall. It can be transmitted ex- 

 perimentally from pig to pig, from pigs to goats, and from goats 

 back to pigs (Gerlach). It is also claimed to pass from the pig 

 to man (Freidberger and Frohner). Young pigs are especially 

 subject to it and one attack confers immunity for the future.
