INFECTIOUS DISEASKS. O^S 



not si'piir:it('(| from tlu' ^kiii iUid siiliculiiiu'ous (.-omu'ctix i' tissues 

 found in stnni«rles. in liuyn«ritis. and in otluT simple inll:iium:it<>r\ 

 trouhles. 



These plands liear a <rii':it resemlilaiice t<» the iiidiiraled "rlaiuls 

 whicli we find in coinieetion with the collection of pns in the sinnses; 

 hilt in the latter disease the <rlands have not the extreme n<!didated 

 feel which they have in glanders. With the jrlands we lind indurated 

 conls, feeling like halls of tangled wire or twine, fastening the glands 

 together. 



The essential symptoms of glanders are the nodide. the chancre, 

 the glands, and the discharge. With the development of the nodules 

 in tlie respiratory tract, according to their niunlier and the amount 

 of eruption which they cause, we may find a cough which resemltles 

 that of a corv/a, a laryngitis, a hronchitis, or a i)roncho-pneumonia, 

 according to the location of the lesions. In chronic glanders we find 

 the siime accessory symptoms that occur in chronic farcy, the hemor- 

 rhage of the nose, the swelling of the legs, the chronic cough, and. in 

 the entire horse, the swelling of the testicles. 



On healing, the chancres on the mucous membranes leave small, 

 whitish, .star-shaped scars, hard and indurated to the touch, and 

 which remain for almost an indefinite time. The chancres heal and 

 the other local symptoms disappear, with the excejition of the en- 

 largement of the glands, and we find these so diminished in .Mze that 

 they are scarcely perceptilde on examination. Din-ing the .'juhacute 

 attacks, with a minimum (piantity (?f local trouhles. in chronic glan- 

 ders and in chronic farcy the animal rarely shows any degree of fever, 

 hut does have a generally depraved aj)i)earance: it loses flesh and he- 

 c«>mes hidel)ound: tlie skin becomes dry and the hairs stand on end. 

 There is a cachexia, however, which resembles greatly that of any 

 chronic, organic trouble, but is not diagnostic, although it has in it 

 certain ajipearances and conditions which often lender the animal 

 suspicious to the eye of the expert \eterimnian. while without the 

 presence of local lesions he would be unal»le to state on what he has 

 based his opinion. 



ACUTE GLANDERS. 



Si/mpfoniJ<. — In the acute form of glanders we find the symptoms 

 which we have just studied in chronic farcy and in chronic glan- 

 ders in a more acute and aggravated foiin. There is a ra])id outbreak 

 of nodules in the resjjiratory tra<t which ra]>idly degenerate into 

 chancres and pour out a considerable discharge from the nostrils. 

 There is a cough of more or less severity according to the amoimt and 

 site of the local eruption. Over the surfac<' of the body swellings 

 occur which are rapidly followed by farcy butt<ms. which in-eak into 

 ulcers; we find the indurated cords and enlargement of thr lym- 

 phatics.
