184 EXPERIMENT STATION RECORD. 



the liuman or bovine type of bacillus. The skiu in no instance showed any 

 visible microscopic changes, and seems to be greatly resistant to the infection. 



Tubercular septum, in the nose of a bovine, P. CHAussfi {Rec. MM. VM., 

 88 {1911), No. 2Jf, pp. 580-585, figs. 3). — The results are given of a histopatho- 

 logical study of a case in which the nasal septum of an 8-year-old cow was 

 affected. The animal had a generalized tuberculosis. 



Improved technique for diagnostic inoculation of animals with tubercu- 

 lous material, R. Oppenheimer {MilncJien. Med. Wchnschr., 58 (1911), No. 41, 

 pp. 2164-2166; ais. in Jour. Amer. Med. Assoc, 57 {1911), No. 21, p. 1731).— 

 The urine of the suspect was injected directly into the liver of guinea pigs. 

 Specific lesions were found to develop in about 16 days. 



The subcutaneous bovotuberculol test for the diagnosis of bovine tuber- 

 culosis, H. Bausch (Die Subkutane Bovotuherkulol prohc fiir die Diagnose der 

 Rindertuherkulose. Inaug. Diss., Univ. Bern, 9111, pp. 27; ais. in Ztschr. 

 Tuberknlose, 18 {1912), No. 5, p. 509). — ^As a result of examining 302 animals 

 in an abattoir at Darmstadt, Germany, the author finds that the tubevculol test 

 when used subcutaneously yields better results than those obtained with 

 tuberculin. A previous eye test will have no influence upon a subsequent 

 tuberculol reaction, but it must be conducted after the subcutaneous injection. 



The vaccination of cattle against tuberculosis, E. C. Schkoedee et al. 

 (U. 8. Dept. Agr., Bur. Anim. Indus. Rpt. 1910, pp. 327-3 'i3; Circ. 190, pp. 327- 

 343). — Previously noted from another source (E. S. R., 25, p. 2SS). 



The medicamental treatment of piroplasmosis, E. Meuleman {Rev. 06n. 

 M6d. V6t., 19 {1912), No. 223, pp. 365-380).— This is a review of recent work. 



Vaccination against bovine piroplasmosis, J. Lignieres {Rev. G&n. M4d. 

 V^L, 18 {1911), No. 213, pp. 489-506; abs. in Jour. Compar. Path, and Titer., 

 25 {1912), No. 1, pp. 59-63). — The author claims to have shown that animals 

 which are very resistant to Piroplnsma bigeminum may be very susceptible to 

 a new piroplasm which he has named P. argcntinum and that the latter may 

 even prove fatal. 



Blood taken from diseased cattle at a time when it contained a maximum 

 number of parasites and kept at from 5° to 8° C. for 30 days, when injected 

 intravenously, frequently caused a mild form of the disease, which was followed 

 by immunity. The parasites present in this blood were found to be smaller 

 than normal, spherical, and apparently multiplying. An intravenous injection of 

 10 cc. of this blood caused about the seventh day a general reaction which lasted 

 for 1 or 2 days. This first vaccine retained its vitality for at least 8 days. 



The methods of preparing the vaccine from blood containing the P. bigeminum 

 by desiccation or freezing can not be applied to the P. argcntinum, because this 

 parasite retains both vitality and virulence after freezing. Since the intro- 

 duction of the method 23.000 animals have been vaccinated. 



Some results of cattle-tick eradication {U. S. Dcpt. Agr., Bur. Anim. Indus. 

 Circ. 196, pp. 4). — This is a summary of the replies received in response to a 

 series of questions sent out in an effort to secure direct evidence from cattle- 

 men and farmers regarding the benefits to the cattle industry of the South 

 which are being derived from the tick-eradication work carried on in coopera- 

 tion between the Bureau of Animal Industry of this Department and the 

 various States within the quarantined area. 



The etiology of pleuro-pneumonia, E. J. Mabtzinovski {Ann. Inst. Pasteur, 

 25 {1911), No. 12, pp. 91Jt-9l7, pi. 1). — The author here reports studies com- 

 menced in 1909 which have led him to conclude that pleuro-pneumonia is caused 

 by a minute gram-negative, polymorphous, nonmotile bacterium, to which he 

 gives the name Coccobacillus mycoides peripneumonice. A magnification of 

 1,000 diameters is necessary in order to distinguish it clearly.
