654 RINGWORM, 



of the coat, tlie symptoms of recorded cases seem to indicate a close 

 relationship with ringworm in the horse and ox. 



In sheep suffering from ringworm, the wool is at first matted into 

 small irregular tufts, which grow larger and more numerous. The 

 coat appears felted together at various points. The neck, chest, 

 shoulders and hack exhibit crustaceous patches covered with hran- 

 like epidermal scales, and the animals suffer from marked pruritus, 

 which causes them to rub and injure the coat. 



Ringworm is very obstinate in the goat. 



Two pigs described by Siedamgrotzky showed irregular, rounded 

 patches, due to trichophyton, from 1 inch to 2 inches in diameter, 

 reddish in tint, without exudation, but covered with abundant scales. 



In the pig ringworm attacks the croup, sides of the chest, flanks 

 and sides of the abdomen, but is commonest on the back and out- 

 side of the quarters. It forms red isolated patches, from 1 to 2 

 inches in diameter, covered with miliary vesicles, which in turn are 

 replaced by brown crusts. The bristles remain unchanged, and are 

 not shed or broken. There is no pruritus. Contagion from pig to 

 pig occurs readily. The disease may be conveyed from oxen to pigs 

 through the medium of litter removed from the cowsheds to the 

 piggery. 



Gerlach was unable to inoculate sheep or pigs with ringworm from 

 the ox. Perroncito mentions a case of contagion from the ox to a 

 lamb. Schindelka has seen sheep contract ringworm as a result of 

 confinement to sheds previously occupied by oxen suffering from the 

 disease. 



Siedamgrotzky successfully inoculated two pigs and two sheep with 

 ringworm from the horse and a goat with the bovine form of the 

 disease. The two pigs inoculated two others by contact. Contagion 

 from the goat to the ox was noted in the canton of Ziirich in 1852. 



Fuller particulars on these heads will be found in a series of articles 

 by Neumann in the Revue Veterinaire, January to June, 1905. 



In 1876 Laillier communicated to a French medical society a 

 letter written by Lespiau describing an endemic of trichophyton dis- 

 ease in the cantons of Ceret and Arles-sur-Tech. Thirty-four per- 

 sons, including twenty-eight children, were affected. A dog was first 

 attacked and seems to have inoculated a pig, which in these districts 

 often lives with the human family. The pig inoculated the human 

 beings. A moist season appears to have favoured the development 

 of the disease. The parts principally attacked were the head, eye- 

 brows, cheeks, and neighbourhood of the genital organs. The sub- 

 jects showed considerable pruritus.
