Foot-and-mouth disease in Sweden in 1914—15, G. KirEKEXJT.F {Medclel. K. 

 Med. Sti/r. [Sweden'], No. 26 (1916), pp. US, pis. 2, figs. 3).— This report deals

Glanders in Brazil. — Observations made on a tour of investigation, J. B. 

 Mendy {An. Sac. Rural Argentina, 51 {1917), No. 3, pp. 25Jf-261, figs. 12). — This 

 article summarizes the possible means of spreading glanders by contaminated 

 drinking troughs, feed, bridles and equipment, public grazing ground, etc. 

 An examination of all the horses and mules in the First Cavalry and Second 

 Artillery during an epidemic of glanders showed that all the horses either 

 had the disease as recognized by clinical symptoms or reacted positively to the 

 mallein test. Observation cases are cited of glanders in man and of -the 

 mallein test in experimental rabbits and in horses having the disease. 



The serum treatment of hemorrhagic septicemia, W. B. Mack and E. Rec- 

 ords {Jour. Amer. Yet. Med. Assoc., 52 (1918), No. 7, pp. 810-819) .—This is a 

 detailed account of the serum treatment of the cattle disease previously noted 

 (E. S. R., 38, p. 487). 



The serum was prepared by injecting horses with increasing doses of living 

 cultures of Bacterium bovisepticum isolated from cattle until their serum 

 reached such a potency that 5 mils given intravenously would protect a rabbit 

 against approximately 1,000 fatal doses of the organism given subcutaneously 

 at the same time. Of 140 cases receiving the treatment 60 died and 80 re- 

 covered, giving a mortality of 43 per cent as against over 95 per cent in un- 

 treated cases. 



Factors apparently affecting the percentage of recoveries after vaccination 

 are as follows: (1) Previous vaccination: Animals previously vaccinated have 

 apparently an 11 per cent better chance of recovery. The vaccine consisted of 

 a 4S-hour bouillon culture of mixed strains of B. bovisepticum killed by the 

 addition of 1 per cent phenol and used in a dose of 5 mils. This was followed 

 in from 10 to 14 days by a 2-mils dose of a 48-hour bouillon culture of a 

 strain of B. bovisepticum which had lost its virulence for cows. (2) Apparent 

 severity of attack as judged by clinical symptoms: There is apparently no 

 relation between the severity of symptoms and chances for recovery. A 

 moderate delay in the administration of serum does not seem to greatly re- 

 duce the chances for recovery provided it is administered before the animal 

 passes into the final stage of collapse. (3) Amount of serum administered: 

 Tabulated results of varying amounts from 30 up to 1,000 mils seem to show 

 that doses in excess of 200 mils are of little value. 



The authors feel that the results obtained by the use of serum therapeu- 

 tically may not be due to specific action, and that possibly nonspecific and 

 even normal serum would produce as good results.
