" Mai de Lure:" A pyemia secondaiT to contagious agalactia of the sheep 

 and goat, H. Cakiuc (Ann. Inst. Pasteur, 26 iW12), No. J,, pp. 281-299, pi. 1, 

 figs. 2). — The author lias found " mal de Lure," which develops secondary to 

 contagious agalactia in sheep and goats, to be due to a new pyogenic bacillus, to 

 which he has given the name " pyobacillus of the sheep and goat." This affec- 

 tion was prevalent during 1911 in the Lure mountain district of southeastern 

 France. The disease is manifested by a purulent sloughing condition of the 

 eyes and udder, suppurative arthritis of the knees, stifles, and hips, and a pro- 

 gressive muscular wasting. 



Hog cholera, E. L. Mooke and T. B. Kelly (South Dakota 8ta. Bui. 13S, pp. 

 370-391, figs. 5). — This bulletin consists largely of a general account of hog 

 cholera, including post-mortem appearances, prevention by artificial immunity, 

 the method of producing and testing potent serum, method of vacciuatiou, sani- 

 tary measures, etc. 



The results of investigations indicate that thei-e is no constant relation be- 

 tween the agglutination reaction of immunizing serum for Bacillus cholerw suis 

 and its potency as shown by actual field trials. Thus it can not be used as a 

 method of standardizing serums for commercial purposes. 



Investigations made to determine the value of the salt solution recovered 

 from the intraperitoneal cavity of hogs Ivilled with acute cholera for hyper- 

 immunization purposes are briefly reported and considered very satisfactory, 

 the virulence of the recovered salt solution having met the standard require- 

 ments. The authors state they can see no reason why it can not be used suc- 

 cessfully in hyperimmunization work. 



New sero-therapeutic tests for hog cholera, P. Stazzi (Berlin. Tierdrztl. 

 Wchnschr., 28 (1912), No. 38, pp. 697-701) .—A ftev giving the geographical dis- 

 tribution of the disease in the districts around Pavia and Milan, Italy, and the 

 preparation of hog-cholera serums, the results of a comparative investigation of 

 the protective value of Ilutyra's and L. W. Gans' serums, and the serums pre- 

 pared at the experiment station for infectious diseases of domesticated animals 

 of the Agricultural Association of Milan, are reported. 



In the first series of tests 38 shotes, 3 months old, weighing from 20 to 22 kg., 

 were treated as follows : Ten received the ISIilan serum, 20 Gans' serum, and 8 

 animals were injected with Hutyra's serum. All of the animals mentioned 

 above and 6 control animals received injections after the second day of 2 cc. 

 of blood obtained from strongly infected animals. Four of the 6 control ani- 

 mals died within 15 to 20 days, and the other 2 went through the course of a 

 light form of the disease. Of the animals treated with the Milan serum and the 

 Gans serum 1 succumbed in each case, while with Hutyra's serum none of the 

 animals became sick. A second set of experiments conducted under the same 

 conditions gave less favorable results. 



In a second series of tests in which an attempt was made to simulate practical 

 conditions animals having natural hog cholera, and others artificially infected, 

 were used. These animals with some controls were housed in the station bams. 

 Far better results were obtained from these tests than from the first series. All 

 of the control animals died of an acute hog cholera, while out of 21 treated 

 animals only 1 died. 



It is pointed out that the serum confers marked immunity, which, however, 

 may not be absolute. The curative action of Gans' new serum was found to be 

 very slight or nil.
