X02 Rabbit Septicemia, Etc. 



die within a short time. Therefore there is a possibility that the 

 appearance of fowl cholera may be associated with the cause of rabbit 

 septicemia and vice versa. Selter observed the disease in a spontaneous 

 enzo-otic form, and found swine plague serum effective in the treat- 

 ment. (Koch & Gaffky, Mitt. d. G.-A., 1881, I.-Lignieres, Bull., 1900, 

 356 [Lit.].— Selter, Cbl. f. Bakt., 1907, XLI, 432.) 



Pleuro-pneumonia of Rabbits. Various authors describe the dis- 

 ease under different names, thus Beck, and recently Kurita as "pleuro- 

 pneumonia," Kraus as "influenza-like rabbit plague," Volk as "rabbit 

 plague," Siidmersen as "infectious rabbit pneumonia," Eberth & 

 Mandry as "spontaneous rabbit septicemia," all these are, however, 

 probably identical or closely related. In all cases there was a fibrinous 

 inflammation of the pleura, sometimes also of the pericardium, fre- 

 quently associated with a catarrhal pneumonia. The symptoms con- 

 sisted in a purulent nasal discharge, difficult respiration, emaciation 

 and rapid course. As the causative agent a fine. Gram-negative, spore- 

 less aerobic bacillus was described which resembles the influenza bacillus 

 of man. They are distinguished from each other by unimportant char- 

 acteristics. (Lit. see Z. f. Tm., 1906, X, 429; also Cbl. f. Bakt., 1906, 

 XLIX, 508.) 



Rabbit Distemper. Described by Lucet as "septic disease of 

 rabbits. ' ' 



It manifests itself in a phlegmonous swelling of the tracheal and 

 laryngeal regions, nasal discharge, difficult respiration and emaciation. 

 The autopsy shows, in addition to a purulent inflammation of the 

 subcutis at the places mentioned and regional inflammatory edema, 

 pronounced acute swelling of the spleen, enteritis and serous exudate 

 in the thoracic and abdominal cavities. A small bacillus (Bac. septicus 

 cuniculi) is indicated as the causative agent. (A. P., 1892, VI, 558.) 



Pyemia of rabbits ; observed by Koppanyi in Belgian hares usually 

 as a severe affection. In acute cases purulent flbrinous pleuritis and 

 pericarditis are present, while in chronic cases subcutaneous cold 

 abscesses develop which may reach the size of a man's fist. After 

 rupturing, which sometimes only occurs after 6 to 8 months, recovery 

 follows not infrequently. The disease is caused by a polymorphous 

 eapsulated bacillus (Pyobacillus capsulatus cuniculi). (Z. f. Tm., 1906, 

 X, 429.) 



Streptothrichosis of rabbits is characterized by a progressive 

 necrosis of the skin which extends to the muscles and tendons. Thrombi 

 develop in the blood vessels and as a result emboli occur in the inter- 

 nal organs, especially the lungs. The streptothrix cuniculi which was 

 demonstrated by Schmorl as the causative agent of the disease, is 

 identical with Bang's bacillus necrophorus. Basset produced an effec- 

 tive immune serum by treating a horse with pure cultures. (D. Z. f. 

 Tm., 1891, XVII, 375; Bull., 1908, 345.) 



Myxomatous affection of rabbits ; observed by Sanarelli in Monte- 

 video and by Splendore in Sao Paolo. At the onset a purulent blepharo- 

 conjunctivitis develops and is rapidly followed by a large swelling of 

 the head, also in the vicinity of the rectum and the opening of the 

 urethra and genital organs. Post mortem examination reveals tumors 

 in the subcutis which have a gelatinous appearance. Further, there
