NOTE ON INFECTIOUS ANy^MIA OF THE HORSE. 



Carre and Valle report an infectious anaemia of the horse, as 

 prevalent and almost constantly fatal in different parts of France 

 and Alsace-Loraine. It is easily communicated by: inoculating 

 the blood or urine of the sick horse, the disease developing after 

 an incubation of 25 days. The convalescent animal transmits 

 the disease for months after apparent recovery, and his urine is 

 still rich in albumen. The microbe survives freezing, but is 

 killed by 212'' F. It is ultramicroscopic, passing through a 

 Pasteur filter. This germ leaves the infected system in the urine 

 and probably in the manure and other secretions. vSanitary con- 

 siderations would demand the scheduling and isolation of in. 

 f ected localities, forbidding the ingress or egress of solipeds ; the 

 disinfection of all stable dung and urine produced in such 

 localities ; its removal and plowing under by oxen ; the destruction 

 of the sick with suitable indemnity to the owners ; and the 

 thorough disinfection of all infected premises and objects. The 

 greatest care should be taken to prevent diffusion of the infection 

 through soiled fodder, litter, harness, drainage, etc. , and water 

 should be given boiled. Purchasers of solipeds should avoid not 

 only the areas known to be infected but also the lands which re- 

 ceive their drainage. For treatment see Vol. I, Pernicious Anae- 

 mia, p. 528.
