TREATMENT OF CHOLERA 217 



Postmortem examination showed changes very similar to those 

 described above. The stomach was acutely inflamed and con- 

 tained a large number of worms. The small intestine was especially 

 discolored in appearance, and the lining membrane of the large 

 bowel was also inflamed and reddened. No ulcers were to be 

 found, however, although most careful search was made. The 

 kidneys showed no dark-colored spots, the spleen was slightly 

 enlarged, but about natural in color. No changes in the bladder 

 and the condition of the liver practically normal. One of the 

 carcasses showed a slight pneumonia in the posterior lobe of the 

 right lung, but this animal had been lying in the shed for nearly 

 twenty-four hours before death, and the pneumonia was undoubt- 

 edly a complication and not the primary disease. 



No evidences of cholera could be found, and the case was pro- 

 nounced an acute inflammation of the stomach and bowels due 

 to improper feeding. Change in the rations was recommended. 

 The hogs were allowed range of a small pasture, and in the course 

 of a week the herd was back in good condition, no more animals 

 being lost. 



Another farmer in the same locality was not so lucky. He, too, 

 had been feeding his hogs on a forced diet of corn, feeding the corn 

 dry. The animals first developed slight symptoms of intestinal 

 disturbance from which they partially recovered. He had a hog 

 buyer from town come out to look them over, with the purpose of 

 selUng of the herd before any more got sick. The price offered was 

 not satisfactory, and so he decided to hold them a few days to await 

 developments. Some change was made in the method of feeding, 

 and the animals improved and appeared to be in good condition 

 again. About ten days later he found two animals dead in the 

 pens. That same evening there was another dead hog. He called 

 up the city buyer and made arrangements to ship the animals the 

 next day. In the morning there were five more dead, and three 

 more died in the car on the way to market. At the packing house, 

 where these animals were slaughtered, over 50 per cent, of the herd 

 were found to be suffering with cholera. 



In this case the animals were in a weakened condition from ir- 

 regularity of feeding, and when the buyer came to ^'isit the farm 

 and came into the hog lots he undoubtedly carried with him cholera
