282 DISEASES OF TRUE INFECTION 



may be treated according to the methods recommended under Diseases 

 of the Skin. 



Conjunctivitis is general!}' treated by a solution of sulphate of zinc 

 (1 to 100), or painting the diseased membranes with a solution of nitrate 

 of silver (1 to 70). This must be followed afterward by a 1 per cent, so- 

 lution of chloride of sodium. " Blennorrhoea of the eyes" should be 

 treated by bathing the parts with some antiseptic solution, such as creolin 

 (1 to 100), corrosive sublimate (1 to 2000), or boric acid (1 to 40), or by 

 painting the mucous memlirane by means of a camel's hair pencil with a 2 

 per cent, solution of sulphate of copper. Ulceration of th^ cornea should be 

 treated with a 3 or 4 per cent, solution of boric acid. Parenchymatous 

 keratitis may be treated with a few drops of a 1 to 100 solution of atropine. 

 After the acute inflammatory symptoms of the eye have subsided blowing 

 calomel directly on the cornea produces good results. 



Infectious Bronchial Catarrh. 



(False or Bench-show Disteinj)cr.) 



Within the last twenty years bench shows have become very numer- 

 ous, and kennels both large and small ai-e legion, and from each kennel one 

 to ten or more of the dogs are being exhibited from time to time, we 

 freciuently observe in these kennels shortly after dogs return from the 

 shows a disease that resembles and is frecjuently taken for distemper. 

 This disease for a better name has been called " Bench-shoAV Distemper." 

 It is decidedly infectious and attacks the large bronchi producing catarrhal 

 bronchitis and a muco-purulent discharge from the nostrils and eyes; 

 with this there is also catarrh of the intestines. The writer has also felt 

 that there may possibly }:)e such a condition, and has intimated that fact 

 under the head of Catarrh of the Bronchia (page 137). 



Etiology. — It is generally seen in large kennels, attacking one animal 

 after another or several at once. It may also be o])served where several 

 dogs have been sent to a bench show, developing shortly after they return. 

 The period of inculjation is three to five days. Another peculiarity is that 

 one attack does not insure immunity from another. The writer has ob- 

 served several dogs that have developed this disease, and the next year 

 repeated the attack after returning from a show. 



Pathological Anatomy. — The lesions found are very similar to those 

 of true distemper, but milder in character. The alterations in the lungs 

 are those of catarrhal i)neumonia. The most frequent condition oljserved 

 is great irritation of the nnicous membrane of the intestines, with more or 

 less swelling of the whole intestinal tract. The follicles and glands of the 

 intestines may be swollen or enlarged, and in rare instances ulcerated, but 

 not to the marked degree seen in distempei'.
