PREVENTION, SYMPTOMS AND TREATMENT

caused by the tapeworm. Examination of the feces for segments, 

 or for ova with the microscope, will alone make the diagnosis pos- 

 itive. The administration of areca nut on the food (3iss-ii), i. e., 

 rftixed with bran or oats, constitutes the most ready treatment. 

 This may be repeated at intervals of three days if not effective at 

 first. The avoidance of infected pastures, the destruction of stable 

 manure by quicklime or burning, and the application of 10 per cent, 

 solution of copperas to pastures are prophylactic measures. 



T. fimbriata attacks lambs in the Western U. S. Symptoms 

 become appreciable in the fall when they fail to develop, become 

 hide-bound and lag behind their fellows. They suffer from de- 

 praved appetite, limp, show malnutrition, and often act in an er- 

 ratic way as if " locoed." Thymol may be given as a remedy 

 (gr. xxx for lambs; 3iiss for sheep) suspended in milk and repeated 

 on succeeding days if not successful at first. 



Cattle. — T. expansa, T. alba, and T. denticulata. The symp- 

 toms are those of digestive disorders and failing in flesh and 

 strength. As compared with disease in dog, pig and lamb, taeniasis 

 is rare. Tartar emetic (5iss-iiss), or arsenous acid (gr. xv), 

 may be given on the food once daily for two or three days and fol- 

 lowed by 1 lb. of Glauber's salts. 



Horses.- — T. perfoliata, most common; also T. plicata and 

 mamillana. The existence of taeniasis in horses is rare and the 

 treatment is the same as for round-worms (see below). 



Poultry. — Taenia infundibuliformis and nineteen other 

 species. Exhibited by diarrhea, emanciation, ruffled feathers, fits, 

 sleepiness and weakness. May be enzootic and is very common. 

 Autopsy will show taeniae in the bowels. Powdered areca nut given 

 in pills, made by the use of butter, may be used in a daily dose of 

 thirty grains, and repeated in three days, for good-sized fowls. 

 The dose varies from gr. x to xlv for poultry of different weight. 

 A cathartic is not usually necessary.
