HEMORRHAGIC SEPTICEMIA 303 



Braxy affects yearling sheep in the fall, and winter months. 

 It is characterized by its rapid, fatal course and the hemor- 

 rhagic areas in the abomasum and duodenum found on 

 necropsy. Icterohematuria of sheep presents on postmortem 

 besides icterus, hemorrhagic inflammation of the abomasum, ■ 

 duodenum and rectum, enlargement of the spleen, the pulp of 

 which contains large numbers of the Piroplasmosis ovum. 



Treatment and Prevention. — Medicinal treatment is largely 

 useless. A slaughter of all sheep chronically affected is recom- 

 mended. The sheep should be removed from infected pastures 

 and a thorough disinfection of the sheepfold should follow. 

 As animal endoparasites probably facilitate the bacterial in- 

 fection, the sheep should not only be kept rid of worms, but 

 kept from worm-brood infested pastures. 



Protective Inoculation. — Good results were obtained in 

 Argentine by the use of a polyvalent vaccine of which lambs 

 were given each \ c.c. injected subcutaneously. Polyvalent 

 immunizing serum was also effective. 



In several herds of infected lambs the serum of the horse 

 which had been hyper immunized with cultures of the Bac- 

 terium ovisepticum proved of practical value. The serum was 

 given simultaneously with the vaccine. In these experiments, 

 as the immunity lasted only six weeks, a second inoculation 

 with vaccine is recommended at the end of one month. This 

 simultaneous method proved efficacious in that it stopped the 

 spread of the disease and in most cases healed lambs already 

 infected. 



Takosis of Angora Goats. — Definition. — Takosis is a chronic 

 contagious disease of Angora goats characterized by weak- 

 ness, emaciation, diarrhea, and pneumonia, which leads to 

 death in from one to eight weeks. 



Occurrence. — The disease is not uncommon in the United 

 States, particularly in the Northern States (Oregon, Missouri, 

 Massachusetts, Virginia and Maryland). As the disease is 

 fatal, and 30 to 85 per cent, of the goats in a herd are attacked 

 during an outbreak, it attains considerable economic impor- 

 tance. 



Etiology. — The cause seems to be a micrococcus, the Micro- 

 coccus caprinus, which is pathogenic for goats, chickens, rab-
