exposed to or infected with foot and mouth di.sea.se, the 

 tigiiros for these being given under the statistics of foot and 

 mouth disease. 



The swine ui)on the premises where sickness resembling 

 hofif cholera has been found numbered between 700 and 800, 

 of which 135 died, and the rest were relea.sed when the 

 disease disappeared from among them. In some instances 

 owners were allowed to kill for market, upon ({uarantined 

 premises, pigs Avhicli were ready for the })ork barrel and 

 showed no symptoms of disease. 



In a number of cases the swine were fed upon city swill 

 or upon swill from hotels. 



Hog cholera is a generic term, applied to diseases of an 

 apparently contagious character among swine. As a matter 

 of fact, these animals seem to have several diseases, resem- 

 bling: each other, but due to different causes. In addition 

 to hog cholera and swine plague, diseases known to be due 

 to a specific cause, pigs sometimes are made sick from wash- 

 ing powder used for cleaning dishes in hotels where the dish 

 water is added to the swdll. Recently the United States 

 Bureau of Animal Industry has been investigating a malady 

 among swine, which occurred in Iowa, the clinical symptoms 

 of which resemble hog cholera, but in which neither the hog 

 cholera nor swine plague bacillus was present, and for which 

 the organism producing it has not yet been discovered. 

 While this disease has been found thus far only in Iowa, it 

 is not unlikely that it may exist in other localities. 



In these outbreaks of disease resembling hog cholera 

 among swine, the premises are quarantined until the sick 

 pigs die or recover, and the pens have been disinfected. 

 These measures seem sufficient to check the spread of the 

 disorder and terminate the outbreak. In addition, changing 

 the food and more attention to cleanliness seem to be bene- 

 ficial. 



Besides the reports of diseases grouped under the term 

 hog cholera, there has been 1 case of tuberculosis quaran- 

 tined, the animal being a sow owned in Wrentham. The 

 inspector of animals in Wrentham made an autopsy upon 

 her, and reported that she was badly tuberculous.
