ANIMAL PARASITES IN THE BLOOD 333 



Diagnosis. The diagnosis is only made by finding the 

 parasites on autopsy or the eggs and embryos in the expecto- 

 ration or blood. 



Treatment. Unsatisfactory . 



Spiroptera sanguinolenta. This is a small, thread-like 

 worm found in different parts of the body, but more particu- 

 larly in the heart and large arterial branches. It is of minor 

 importance as the infestation is of rare occurrence in small 

 animals. The symptoms are those of anemia and heart 

 weakness and are not characteristic. A microscopic exami- 

 nation or a necropsy is necessary in order to confirm the 

 diagnosis.
