86 EXPEKIMENT STATION EECOED. 



A general order, which follows this account, was designed to meet the 

 requirements of the case with as little loss to importers as possible. 



A new sheep disease caused by Diplococcus (Streptococcus) lanceolatus, 

 A. Gaertneb {Berlin. Tierdrztl. Wchnschr., 26 {1910), No. 30, pp. 595-597; 

 Cenfbl. Balct. [eic], 1. AM., Orig., 54 {1910), No. 6, pp. 5^6-563).— A. description 

 of the clinical and pathological findings with cases of this disease, which was 

 found at several points iu Germany. A bacteriological examination of all the 

 internal organs revealed the presence of a lancet-like diplococcus which grew 

 well in agar, blood agar, potato, Loeffler's serum, bouillon, and milk. 



The scab act, 1909 {Dept. Agr. Orange River Colony Bui. 21, pp. 121-1J,2).— 

 This act provides for the eradication of sheep scab in sheep and goats. 



Diseases of the hog, A. T. Peters {Bd. Live Stock Conirs. III. Bui. 2, pp. JfJ/, 

 figs. 9). — Brief popular accounts are given of the many diseases to which the 

 hog is subject. 



Report of the veterinarian, M. Jacob {Tennessee Sta. Rpt. 1909, pp. 112, 

 113). — During the year the efficiency of hog cholera immunizing serum was 

 demonstrated in several herds. Two pigs immunized at the station were housed 

 in a pen with 9 pigs affected with hog cholera. Although 7 of the diseased pigs 

 died and the other 2 gradually recovered but remained unthrifty for several 

 months, the 2 vaccinated pigs never lost a meal and continued to fatten. During 

 an outbreak of the disease on another farm, 45 unvaccinated hogs died, while 

 only 2 of 3G animals vacciriated by the serum-alone method succumbed and both 

 of these were suffering from the disease when treated. A sow that was vaccinated 

 remained well, while her 5 pigs, which were unvaccinated, died of the disease. 



[Krafft's vaccine against hog cholera], K. von Sande {Berlin. Tierdrztl. 

 Wchnsehr., 26 {1910), No. 29, pp. 581, 582).— A criticism of Krafft's method of 

 preparing vaccine, which the author, like Poppe (E. S. R., 23. p. 486), does not 

 consider of value. 



Hog cholera and serum vaccination, A. T. Peters {Bd. Live Stock Gomrs. 

 III. Bui. 1, pp. 13, pis. 6). — This is a popular account. 



Sporothrix and epizootic lymphangitis, C. G. Page, L. Fbothingham, and 

 J. B. Paige {Jour. Med. Research, 23 {1910), No. 1, pp. 137-150, pis. .5).— Studies 

 of an organism obtained in pus from afi'ected horses are here reported. The 

 affection, which occurred among horses and mules in a limited district in west- 

 ern Pennsylvania, had previously been reported to be epizootic lymphangitis. 



"The disease is said to be characterized by the appearance i subcutaneous 

 nodules with thickening of the surrounding lymph vessels. The nodules break 

 down, forming multiple chronic abscesses, which as a rule finally heal. The pus 

 is known to contain the infectious agent or virus." 



The results have been summarized as follows : " The horses from which the 

 organism described above was isolated were apparently not affected with the 

 eiiizootic lymphangitis of Tokishiga. The only organism to develop — a spo- 

 rothrix — is unlike the Saccharomyces farciminosus, but is identical with that 

 isolated by Dr. Hyde from a man. It is probably the same as that isolated by 

 Schenck, Hecktoen and Perkins, de Beurmann and others. The sporothrix 

 exists in very limited numbers in the pus from closed lesions — more numerous 

 in open lesions — of affected animals and persons. It will remain alive in dry 

 pus kept at a mean temperature of 7° C. for at least 3 months. It is infectious 

 for man, horses, mice, rats, and presumably some other animals. There seems 

 to be no better culture medium than potato, upon which growth is visible in 

 2 to 4 days at a temperature of 20 to 28°."
