HELMINTHIASIS 159 



polymorphs 85%, and eosinophils 2%. There were 72 erythro- 

 blasts per cmm. The larvae averaged about one per cubic milli- 

 meter. At the postmortem many adult worms, Filaria immitis, 

 were found in the right auricle, vena cava and pulmonary artery. 

 The changes in the blood are evidently not due to the filarise. In 

 another dog they found larvae, probably of Filaria lewisi. In this 

 case the blood had 6,235,000 red corpuscles, 104% hemoglobin 

 and 7,716 leucocytes of which there were 13.6% lymphocytes, 

 4.2% large mononuclears, 78.1% polymorphs, and 4.2% eosino- 

 philes. In the reported cases of filariasis in man it seems that 

 eosinophilia is present in recently acquired cases. Calvert in 

 one case found leucocj'tosis present, 18,000-26,600, with the 

 eosinophiles varying irregularly between 22.2 to eight per cent. 

 In a second case of much longer duration he found the leucocytes 

 varying between 7,600-14,000; the eosinophiles from six to 20%. 



Teniasis. — In cases of Taenia solium, T. saginata and T. nana 

 in man, Bucklers found the eosinophiles increased (5 to 10%). 

 Launois and Weil found eosinophilia in cases of T. inermis. Cabot 

 states that in the ordinary cases of tape worm many of which he 

 has examined he has not usually found eosinophilia. 



Uncinariasis. — In most cases in man there is moderate anemia 

 with the hemoglobin more affected than the red corpuscles. In 

 many cases anemia of the pernicious type with megalocytes, 

 microytes, megaloblasts and increased color index is seen. A 

 moderate leucocytosis is frequently found. Ashford, however, 

 regards leucocytosis when it occurs as due to complications. The 

 eosinophiles are nearly always increased and are sometimes very 

 numerous. As high as 72% is recorded. 



Trichocephalus, Strongylus and Oxyuris. — In 12 cases in man 

 in which Trichocephalus was the only worm found in the feces, 

 P. F. Brown found that the eosinophiles rarely fell below five 

 per cent. 



In sheep infested with Strongylus contortus, Law states that 

 there is a deficiency of red corpuscles with many peculiar cells 

 larger than normal red corpuscles and distorted (poikilocytosis). 

 Counts were not given. 



Runeberg observed a case of pernicious anemia in man due to 

 Oxyuris. Bucklers reported a case of Oxyuris in man with 16% 

 eosinophiles and in another case of Oxyuris and Ascaris there was
