In Dogs. In Man. 233 



In the treatment the same principles apply as given in purpura 

 hemorrhagica of the horse. In the cases where in one stable several 

 animals became affected consecutively, the disease was checked by 

 changing the feed and the drinking water (Minder) as well as by dis- 

 infecting the stable (Eichhorn).

Purpura Hemorrhagica of Dogs. Lellmann observed in a 6-year 

 old dog symptoms which indicated an affection of purpura hemorrhagica. 

 The emaciated animal, M'hich had no fever, showed weakness and a 

 Aveak heart action, also swelling of the hind parts, ascites, epistaxis, 

 hematuria, and bloody excrement. The autopsy revealed hemorrhages 

 in the spleen, liver, kidneys, in the serous membranes, in the skin, in 

 the subcutaneous connective tissue, and in the muscles. In another 

 case there was anemia (pale mucous membrane, small pulse, anemic 

 heart murmurs) bloody vomiting and diarrhea, also numerous hemor- 

 rhages in the skin which comprised the principal manifestations. 

 The autopsy findings in this case resembled those of the first. Lellmann 

 considers both cases identical with purpura hemorrhagica of the horse. 

 (B. t. W., 1897, 509; 1902, 266.) 



Raitsits observed in a dog bluish-red, later confluating spots 

 on the abdomen and on the inside of the thighs, petechiae on the con- 

 junctivae, swellings of the gums, hazel-nut sized al^scesses on the phre- 

 num of the tongue, albuminuria and hematuria. The autopsy revealed 

 hemorrhages under the skin, also in the conjunctivae, and a hemorrhagic 

 inflammation of the rectum. (A. L., 1906, 421.) 



Purpura Hemorrhagica of Man. This disease (morl)us maculosus 

 Werlhofii, purpura hemorrhagica), is caused according to Kolb, by a 

 small Gram-positive bacillus, the bacillus haemorrhagicus, while accord- 

 ing to Letzerich it is caused by the bacillus purpurae haemorrhagicae. 

 The hemorrhages which appear in different parts of the body in asso- 

 ciation with the disease cause it to somewhat resemble purpura hemor- 

 rhagica of animals; however, the possible relations of the two diseases 

 have not yet been established. It should be mentioned that in a case 

 reported by Bock a stable attendant became affected with Werlhof's 

 disease several days after the death of a horse with purpura hem- 

 orrhagica.

Scarlatinoid of Horses. Under this name Champetier described a 

 disease of young horses which resembled scarlet fever of man. In a 

 mild form of the affection there is a fever reaching 103-104°F., inappe- 

 tence, frequent pulse and cough, injection and petechiae of the mucous 

 membranes, further a peculiar pustular exanthema of the skin, and 

 edematous swellings of tlie extremities. In the more severe form the 

 enumerated symptoms are more intense and bronchial catarrh, catarrhal 

 pneumonia, and nephritis may also develop. (Les maladies du jeune 

 cheval. Paris, 1892.) 



The latter of these forms has also been observed by Marek in 

 an 8-year old mare. Simultaneously with a marked swelling of the 

 nasal mucous membrane diffuse edematous swellings appeared on the 

 abdomen and on the hind extremities; nodules developed on the skin 

 of the rump, the head and neck, and later round ulcerations appeared
