Parasitic Mange in Horses. 



are similar to the symptoms of the sarcoptic variety, but in 

 psoroptic mange the affected areas of skin are more clearly 

 defined, and the rate of spread to surrounding parts is slower 

 than in the first-mentioned variety. In bad cases spread over 

 large areas it looks very like sarcoptic mange, and differentia- 

 tion depends on the identification of the mite. 



Symbiotic Mange. — This is usually confined to the extremi- 

 ties of the legs, more particularly the hind ones. It develops 

 slowly, and exceptionally it may invade other parts of the 

 body. This variety is fairly easily cured on the application 

 of the ordinary remedies. 



Method of Spread. — Mange being solely due to either of 

 the before-mentioned mites, all cases can be traced to con- 

 tagion from an existing or pre-existing case. The disease 

 may be spread directly from one animal to another, or, as 

 more frequently happens, indirectly through the medium of 

 litter, rugs, grooming utensils, saddlery, harness, stable walls, 

 partitions, &c. 



Prevention. — On the first suspicion of mange the affected 

 animal should be isolated, and care taken that no grooming 

 utensils, rugs, &c, that have been used on affected animals 

 are used on others until after disinfection. 



In addition to treating an animal for mange, particular 

 attention must be paid to cleansing and disinfecting the stable 

 and articles that have been used for or about the patient. 



Although parasitic mange in horses, asses, and mules is not 

 the subject of administrative action throughout Great Britain, 

 a model Order issued by the Board of Agriculture and 

 Fisheries under the Diseases of Animals Acts is in operation in 

 the districts of many local authorities. 



The Board, on application by a local authority, are prepared 

 to issue such an Order, prescribing notification, detention, and 

 treatment to be carried out by owners of horses, asses, and 

 mules affected with mange in the area in which the Order 

 operates. 



The Orders issued are made applicable only to the forms 

 of parasitic mange known as sarcoptic mange and psoroptic 

 mange. 



In a district in which a Parasitic Mange Order is in force, 

 every person having in his possession or under his charge a
