ANIMAL PARASITIC INFECTIONS 459 
ostoma spinigerum siamense. A single specimen of the parasite described by 
Levinsen' was found by Deuntzer in Bangkok, Siam, and was obtained from 
a@ young Siamese woman who suffered from a small tumor of the breast which 
had developed in the course of a few days. After the disappearance of the 
tumor, nodules the size of beans were found in the skin. From one of these 
the worm was obtained. Brumpt? notes that similar tumors were also found 

No. 396. — Photomicrograph of section of nodule in the stomach of leopard Felis pardus 
containing Gnathosthoma spinigerum Owen, illustrating thinning of the epithelium on the 
right and bulging of the muscular coat on the left. Cross-sections of the parasites in the 
submucosa are visible in the center of the nodule 
by Deuntzer in two other sick persons after a slight febrile period. In one of 
these five or seven worms were expelled. He also calls attention to the fact 
that the parasite has been encountered again in Siam by Kerr (Leiper), by 
Robert (1922), and in a Chinaman from the Malay States by Samy, and in 
a Chinaman in a case of ‘creeping disease” (Y. Ikegami, H. Tamura). Appar- 
ently no mention has been made of intestinal invasion with this parasite in 
man.
