330 ANEMIA 



cases where the ulcerative processes are well established. 

 When general symptoms of anemia and cachexia are evident 

 the prognosis is bad. 



Treatment.— This disease can be readily prevented when a 

 variety of food is allowed and good sanitary conditions 

 prevail. 



The early indications in the treatment are to change and 

 regulate the diet. Give the patient nourishing food, such 

 as meat, milk, eggs, etc. Iron preparations (iron and 

 quinin citrate, pulverized iron, saccharated carbonate of 

 iron) are the most satisfactory for the anemia which is nearly 

 always present. Tincture of nux vomica (0.3 to 0.5 daily) 

 or tincture of gentian (0.5 to 0.8 twice daily) is useful as a 

 tonic. 



Local applications should also be used. Swab the gums 

 and other affected mucous membranes of the mouth with 

 tincture of myrrh once or twice daily. 



When hemorrhages are present they must be controlled 

 by appropriate treatment. 



ANIMAL PARASITES IN THE BLOOD. 



Filar idee. Metastrongiilince. 



Several species of animal parasites have been found 

 infesting the blood and. circulatory organs in small animals. 

 The dog is most frequently affected. In several districts of 

 the United States, Canada and Mexico, the condition has 

 been reported a number, of times. The Dirofilaria immitis, 

 Hematozoon Lewisi, Haemostrongylus vasorum and the Spi- 

 roptera sanguinolenta are the most important ones found. 



Dirofilaria immitis (Filaria immitis).— Occurrence.— This 

 blood affection has been observed very commonly in the 

 dog, particularly in Japan, China, and in some sections of 

 North and South America. The United States is fairly free 

 from the infestation, but it is quite possible that many cases 

 have been overlooked. 



Etiology.— The Dirofilaria immitis is a long, white worm, 

 the male being 12 to 18 cm., and the female 20 to 30 cm. long
