Glanders. 239 



The mucosa may even be drawn or puckered around the cicatrix, 

 making the illusion all the more complete. 



The submaxillary swelling is even less sensitive than in acute 

 glanders and produces the same sensation as of an aggregation of 

 small, hard, pea-like, masses with no tendency to ulcerate. 



Symptoms of Cutaneous Glanders {Farcy^ in Solipeds. Acute 

 cutaneous glanders has been already referred to under nasal 

 glanders. The chronic type is often less characteristic, yet may 

 be detected by careful observation of the .symptoms. The main 

 symptom may be the swelling of a joint with more or less en- 

 gorgement of the limb from attendant lymphangitis. There 

 can usually be detected around the margins of such swellings firm, 

 tender cords representing the larger lymphatic vessels and often 

 branching in their course. In the absence of the engorgement, or 

 when it is slight, these cords may be the main evidence of the 

 disorder, and in the hind limb usually follow the course of the 

 flexor tendons on the inner side of the digit, metacarpus and 

 thigh. At intervals along the line of the cords appear nodular 

 masses (farcy buds) varying in size from a pea to a hen's ^g%, 

 and showing a great disposition to soften and discharge a glairy, 

 sanious or more or less bloody liquid. The inner sides of the 

 fetlock and tarsus are favorite seats of these nodules but they 

 may form at any point. On the trunk also the corded lympha- 

 tics and nodules follow the lines of the veins and lymphatics, and 

 here there may be the complication of large intermuscular 

 abscesses often in connection with the groups of lymphatic 

 glands. 



Latent or occult glanders is often met with, the indolent, specific 

 lesions being confined to .some internal organs, like the larynx, 

 lungs or womb, or to the testicles, the nasal diagnostic symptoms 

 being absent. A chronic cough, with a slight purulent discharge 

 from the nose, a chronic leucorrhoea, a .swollen testicle, or .simply 

 a persistent low condition or weakne.ss without apparent cause, 

 may be the only indications, and special means of diagnosis are 

 demanded. 



Special Means of Diagnosis. In occult cases, the disease may 

 be identified by inoculation, or by the mallein te.st. 



Inoculation is best performed on a very susceptible animal. If 

 the suspected discharge from the nose, vagina, open sore or pre-
