MEASLES. 



Measles in swine is a different disease- entirely to that called 

 measles in man. 



Causes. In swine, measles are caused by a parasite (the blad- 

 der worm) from eating the eggs of the tapeworm of man (taenia 

 solium) in its food; dogs also carry and void the eggs of the tape- 

 worm, and hence care should be taken that swine do not eat 

 their excrement. If the flesh of measly pork is not thoroughly 

 cooked before being eaten by man, he is sure to be affected by 

 tapeworm. Since there is always danger that some of the cysts 

 may escape death in cooking,, it is never safe to eat measly pork. 



This hydatid, or bladder worm (cysticercus cellulosa), is what 

 forms measles in pigs; it becomes encysted in the muscles, brain, 

 liver, lining membranes, etc. 



Symptoms. The symptoms of the disease are a cough, run- 

 ning from the eyes, discharge from the nose, and weakness of 

 the hind quarters, with general debility. The cysts, some of 

 which are about the size of a grain of barley, may be seen scat- 

 tered through the muscles and other tissues of the pig. Their 

 presence may sometimes be detected in the eye or under the 

 tongue. When once encysted, further annoyance to the animal 

 is stopped. 



Treatment. But little can be done for this disease. If reeog- 

 nized at the beginning of an attack, the following powders might 

 pass the eggs from the bowels: 



Sulphur 4 drams. 



Saltpetre J dram. 



Mix, and give as one powder every day for two weeks.
