J 38 NECK MANGE IMPETIGO COLLI. 



NECK MANGE IMPETIGO COLLI. 



This is the Mahnen and Halsgrind of the Germans, and 

 consists in a pustular eruption, which occurs at the root of 

 the mane, and on either side of the neck. The pustules are 

 about the size of peas, and get covered by yellowish, or yel- 

 lowish-brown scabs, to which the hairs adhere. A purulent 

 discharge is apt to accumulate beneath the scabs. The 

 disease is especially prevalent in spring, and yields to mild 

 treatment. 



A similar eruption occurs occasionally at the root of the 

 tail, and is attended with much itchiness. This is chiefly 

 caused by dirt, and is cured by attention to cleanliness, 

 washing with soap and water, &c. 



IMPETIGO LAEVALIS. 



This pustular disease assumes various forms in the lower 

 animals. In all young animals eruptions are apt to occur 

 about the lips, and various descriptions have been published 

 of impetigo of the face and lips in calves, lambs, goats, 

 and pigs. 



Often in lambs, either in the under or lower lip, are seen 

 round pustules, from which a thick scab or crust drops off in 

 a few days, leaving a red and inflamed skin. In calves the 

 eruption occurs mostly on the upper lip, and there is a con- 

 tinuous ' breaking out/ with an extension of the disease into 

 the mouth, and around the nasal apertures. In pigs the 

 impetigo occurs around the eyes, and spreads over the neck 

 and back. 



The causes of impetigo are richness of the milk which 

 young animals suck, and, later in the season, it is due to 

 green food, which may sometimes contain irritating mate- 

 rials ; not unfrequently we find that lambs, folded on Ion?
