414 DISEASE IN WILD MAMMALS AND BIRDS 
distended with a great quantity of undigested food and gas ; no worms. 
Serosa and wall normal but anemic. Duodenum normal. Jejunum con- 
tains numerous worms about 1 to 1.5 cm. long ; it is distended with gas. 
The pancreas is large, soft, like fat, white ; it extends between the layers 
of mesentery along the course of the duodenum; at first the pancreas 
was mistaken for fat. 
Histological Notes. — Spleen shows a distinct overgrowth of trabec- 
ulse. Beyond this there is nothing pathological. Liver shows distended 
portal venules in which there are chains of bacilli. There is no especial 
fibrous overgrowth of capsule of Glisson; capillaries are choked 
with shadow corpuscles and here too, long chains of bacilli may be seen ; 
parenchyma cells show postmortem change. Adrenal is the seat of 
postmortem degeneration, not congested, nor is there any evidence of 
bacterial invasion. The kidney shows no interstitial changes, in fact 
the section seems to be entirely normal save for moderate congestion. 
Vessels show no bacteria.
