98 Fowl Cholera. 



Diseases simulating chicken cholera : 



Infectious enteritis of chickens; observed repeatedly in England 

 and Ireland by Klein. Tlie causative agent (Bac. gallinarum) greatly 

 resembles the bacillus of fowl cholera. However, it does not kill pigeons 

 and onlv exc<^ptionally rabbits. (Cbl. f. Bakt., 1889, V, 689; 1895, 

 XVIII, 105.) 



Enzootic pneumo-pericarditis of turkeys; observed by M'Fadyean 

 and later by Jowett. The bacillus also resembles that of chicken cholera. 

 However, it is motile and non-pathogenic for chickens as well as for 

 water fowl. (J. of Comp. Path., 1893, VI, 334; Ibid., 1908, XXI, 324.) 



Cholera of water fowl; observed in Germany by Willach. The 

 bacillus is distinguished from that of fowl cholera by its motility, is 

 only slightlv pathogenic for hens, and non-pathogenic for pigeons. (Cbl. 

 f. Bakt., 1896, XX, 187.) 



Disease of swans; observed in the Zoological Garden of Antwerp 

 by Tretrop. The liacterium develops only slightly on potato, and causes 

 in swans a caseation of the lymph glands ; chickens are not susceptible. 

 (A. P., 1900, XIV, 224.) 



Diseases apparently different from fowl cholera: 



Cholera of ducks; observed in the Zoological Garden of Paris 

 by Cornil & Toupet. The bacillus stains well by Gram's method and 

 grows well on potato ; chickens, pigeons and guinea pigs are not sus- 

 ceptible, rabbits to only a slight extent. (C. R., 1888, CVIII, 1747.) 



Epizootic dysentery of chickens and turkeys ; described by Lucet. 

 The course of the disease is from 9 to 13 days. The bacillus thrives 

 well on potato and kills guinea pigs by intravenous inoculation. (A. P., 

 1891, V, 312.) 



Disease of ring-dove; observed in France by Leclainche, and is 

 characterized by its rapid course, somnolence and diarrhea. The bacillus 

 (Bac. cholera? columbarum) thrives on potato; chickens are not at all 

 susceptible, while other fowl show only a slight susceptibility. (A. P., 

 1894, VIII, 490.) 



Disease of pigeons; observed in New Jersey by Moore. Cerebral 

 symptoms predominate in this disease. On autopsy meningitis is found 

 to be present, while intestinal symptoms are absent. The bacillus re- 

 sembles Bac. suipestifer; it grows on potato. (Bur. Anim. Indus., Bull. 

 No. 8, 1895, 71.) 



Infectious enteritis of pheasants; observed in the Zoological Gar- 

 den of Milan l)y Fiorentini. The affected animals are not somnolent. 

 Autopsy does not reveal small hemorrhages. The bacillus is not motile ; 

 it forms on potato a honey-like growth and produces indol in peptone 

 bouillon. Chickens, guinea pigs and rabbits are not susceptible. (Soc, 

 ital. di. sc. nat., 1896, 89.) 



Septicemia of ducks ; observed in Italy by Lisi. The affected birds 

 show purulent conjunctivitis and keratitis. The bacillus liquefies gelatin 

 gradually and forms a brownish growth on potato; chickens are not 

 susceptible to artificial infection. (II Med. zooiatrio, 1890, 415.)
