154 THE VETERINAEIAN 



Tkeatment : It is not advisable to treat tuberculosis. 

 Thus far, medicine has failed to relieve the affected 

 animal, or kill the bacillus of tuberculosis in a living 

 animal. The infected animals should be disposed of on 

 account of tubercular cows giving birth to tubercular 

 calves, the milk being unfit for human consumption, un- 

 less it is thoroughly pasteurized. Infected cattle should 

 be separated from healthy ones, as the disease spreads 

 very rapidly. Drinking and feeding troughs are a 

 means of spreading the infection, therefore, suspected 

 cases of tuberculosis should be tested and if the animals 

 react, they should be slaughtered, and if the disease is 

 localized', passed for human consumption. The meat of 

 animals suspected of having tuberculosis, or reacting 

 from tuberculin test, should be well cooked. 



TWISTED STOMACH WORM 



Cause: Cattle become affected with this worm by 

 grazing in pastures in which infested cattle have grazed 

 and scattered their droppings. The worms in the 

 stomach produce a multitude of eggs of microscopic size, 

 which pass out of the body wdth the feces. In w^arm 

 weather, these eggs hatch in a few hours ; if the temper- 

 ature remains about freezing point, they soon die. • The 

 eggs are also destroyed by dryness, but, on the other 

 hand, moisture, if the weather is warm, favors their de- 

 velopment. The twisted worm measures one-half inch 

 to one and one-half inches in length. 



. Symptoms: General weakness, loss of flesh, anemia, 

 dullness, capricious appetite, excessive thirst, paleness of 

 the skin and mucous membranes of the mouth and eyes, 

 and dropsical swelling, especially that of the lower jaw. 

 Diarrhoea always accompanies this condition and if the 

 feces is carefully examined the small worms may be seen 

 wriggling about like little snakes, or when an animal 

 dies, and the fourth stomach is opened, these worms can 

 be seen in large quantities.
