PARASITES 167 



stomach and intestines of a month-old puppy were 

 found on postmortem examination to be tightly 

 packed with worms, which, when removed, com- 

 pletely filled a six-ounce bottle. 



Treatment. — All solid food must be withheld for 

 twelve hours, when capsules containing calomel and 

 santonin, one-half grain of each, should be admin- 

 istered every three hours until purgation takes place. 

 The following prescription has given complete satis- 

 faction to the author in numerous cases :_ 



IJ Fluidextracti spigeliae, 



Fluid'Extracti sennae, aa oz. i 



Sig. — Give 15 to 30 minims every morning until three doses 

 have been given. 



There are many other vermifuges applicable, but 

 whatever one is used, a laxative should either 

 be combined with it or administered after the last 

 dose, and in every case of worm infestation the 

 treatment should be repeated every two weeks until 

 the feces show fio evidence of parasites or of their 

 ova. All feces of infected dogs should be burned 

 to prevent other animals from becoming infested. 



Oxyuris Vermicularis 



This is a small, white, thread-like worm, the male 

 from two to three millimeters long, the female from 

 nine to ten millimeters long. These parasites in- 

 habit the rectum and cause considerable irritation 

 and anal pruritus; the patient continually drags 

 the anus along the floor to relieve the itching. 



Symptoms. — Anal pruritus and the presence of 

 the parasites in the feces prove the presence of the 

 parasite. 



Treatment. — A laxative should be administered, 

 followed by enemas of a saturated solution of sodi- 

 um chlorid or a strong infusion of quassia chips.
