98 Fowl Cholera. 



Diseases simulating chicken cholera: 



Infectious enteritis of chickens; observed repeatedly in England 

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

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

 and only exceptionally 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 slightly 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 bacterium 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 Prance by Leclainehe, and is 

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

 (Bae. eholerae 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 by 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.)
