The epicrisis to a foot-and-mouth disease invasion, O. Keueger {Berlin. 

 Tierarztl. Wohnschr., 26 {1910), No. 52, pp. 1058-1060).— The author discusses 

 the various factors involved in the epizootiology of foot-and-mouth disease, and 

 points out the part which man may play in the dissemination of the disease. 

 He recommends certain precautionary measures in this direction. 



Mastitis caused by a diplococcus, B. Mezey and I. Koppanyi {Allatorvosi 

 Lapok, 33 {1910), No. 5, pp. -',9, 50; abs. in Berlin. Tierarztl. Wchnschr., 21 

 {1911), No. 5, pp. 77). — Thirty-sis animals in one barn were examined and 

 found to be infected with a diplococcus which grew well upon agar and formed 

 round, ^ay-white colonies, and which took Gram. 



The disease manifested itself by the formation of nodular growths under the 

 subconnective tissue of the mammary gland and which went on to abscess for- 

 mation. It could be transmitted artificially to other animals. The author 

 believes that the disease originated from infected straw. After applying an 

 ointment consisting of boric acid, silver nitrate, and lanolin, the abscesses healed 

 in 12 days. 



Bacteriolog'ical investigations in regard to the causative agent of acute 

 mastitis, with particular reference to the cooperation of the bacteria of the 

 meat poisoning group in the production of the disease, Zwick and Weichel 

 {Ard. K. Gsmllitsamt., S't {1910), No. 1,, pp. 59i-//'/5).— The results of a bacteri- 

 ological examination of 21 cases of acute mastitis showed that in most instances 

 the disease was caused by micro-organisms of the coli-aerogenes group. The 

 results further show that a septic inflammation of the udder or a classic 

 mastitis can be brought about by the bacteria of the meat-poisoning group. 



The lecithin content of milk under pathologic conditions, L. "W. Fetzer 

 (A6s. in Science, n. ser., 33 {1911), No. S-}4, p. 339).— "The results show that 

 milk obtained from animals suffering from mastitis contains less lecithin than 

 the milk obtained from healthy animals. It was further noted that where a 

 diminution in the lecithin content took place there was a corresponding decrease 

 in the fat content." 



In regard to the biological characteristics of colostric and mastitis milks, 

 M. Sassenhagen ( tiber die Biologischen Eigenschaften der Colostral- und Mas- 

 titisynUch. Inaug. Diss., Univ. Bern, 1909, pp. 56). — Colostric and mastitis milks 

 from cows were both found to contain many cellular structures, as well as the 

 protein substances usually contained in blood. Biologically considered, the 

 secretion obtained during the colostric period or from cases of mastitis behave 

 in many respects alike, as bacteriolytic haptines and hemolysins. Complement 

 and antibody substances were practically always present. There were, how- 

 ever, certain differences between colostric and mastitis milks; mastitis milk, for 

 instance, contained many more bacteria and had a higher reducing value for 

 methylene blue, although colostrum during the first few days also has a strong 

 reducing reaction. A further difference is the fact that the Schardinger re- 

 action is obtained with mastitis milk, but not with colostric milk. 



The above findings were also characteristic for woman's and goat's milk. 



In regard to the so-called pseudorabies, Zwick {Arb. K. Gsndhtsamt., 36 

 {1911), No. 3, pp. 382-408; ahs. in Ztschr. Immunitdtsf. u. Expt. Ther., II, 

 Ref., 3 {1910), No. 7, p. 810). — Tests were made with virulent material 

 emanating from Hungary. The brain substance, urine, blood, and blood serum 

 were found to be virulent, but the filtrate from a Berkefeld filter was aviru- 

 lent. The brain substance was found to be virulent after a period of 8 

 months. Desiccation and boiling destroyed the virus. 



The disease is not contagious, and the incubation time was found to be from 

 36 to 96 hours, which is different from that in rabies. The author found bodies
