Sercimmunization (Marra) of sheep and goats infected with contagious 

 agalaxy, B. Bianchini {Gior. Med. Vet., 67 {1918), Nos. ',l. pp. 617-6.!!: .',.',. 

 pp. 665-671). — The symptoms of contagious agalaxy arc d< Bcrlbed and case re- 

 ports are given of the successful use of the antiagalactlc serum of Marra and 

 Cocciante (E. S. R., 31, p. 884) as a prophylactic and therapeutic agent. 



From the results obtained, the author concludes that the serolmmunlzation 

 of sheep and goats can bo effected at any period, even in advanced pregnancy 

 or* during milk production, and that the passive immunity conferred by the 

 serum is gradually transformed into active immunity. It is recommended that 

 serolmmunlzation be practiced methodically every spring on all the animals 

 in the dock.

Swine diseases. R. A. Obaig (Indiana Sta. Rpt. 1918, pp. 72, 73). — In con- 

 tinuation of work on hog cholera, previously noted (E. S. K.. 38, p. 688), further 

 investigations are reported on the value of a mixture of desiccated hog cholera 

 blood and antihog cholera serum as an immunizing agent which Indicate that the 

 desiccated cholera blood present in the mixture played no part in Immunizing 

 the animals which withstood the inoculation with virulent blood, other studies 

 are reported indicating that a hog which lias recovered completely from cholera 

 is not a carrier of the disease, that the di ease is evidently not transmitted by 

 internal parasites, such as lungwornis and roundworms, and that filtration has 

 no effect upon the virulence of hog cholera blood. 



Experimental results obtained in a study of hemorrhagic septicemia and 

 necrobacillosis of hogs are summarized as follows: " rigs that were fed diseased 

 tissues from hogs showing marked lesions of hemorrhagic septicemia developed 

 abnormal temperatures. Sick pigs taken from outbreaks of hemorrhagic sep- 

 ticemia did not communicate the disease to healthy pigs when placed in a pen 

 with them. Pigs inoculated with blood from hogs that had been immunized 

 against hog cholera and afterward came flown with hemorrhagic septicemia 

 remained well. When exposed t' 1 hog cholera later, they sickened and died. 



"Pigs f<~<\ diseased tissues from bogs showing marked lesions of neero- 

 bacillosis showed such symptoms as loss of appetite, elevation in temperature, 

 and diarrhea. All quickly i ed, bul when exposed to bog ■ bolera later 



contracted the acute form of the dist
