584 DISEASE IN WILD MAMMALS AND BIRDS 
and indefinite outline. The bronchus itself is deeply congested and eon- 
tains a grumous mass. The peribronchial lymph nodes are small, soft, 
pink, homogeneous. The heart is negative. The liver is large, surface 
smooth, edges sharp, color deep purple, consistency soft. Section surface 
is glistening, smooth, moist, very dai'k purple with obscure markings. 
The gall-bladder contains fluid brown bile ; common duet is patu- 
lous. The spleen is soft, tough, capsule pebbly, section surface is 
mottled, light and deep pink, follicles and trabeculae not distinguished. 
The kidney capsule is smooth, strips easily leaving a smooth purple 
surface, section surface is glistening, deeply congested, striae obscure 
but seem normal, glomenili not visible, organ is soft. The gums and 
teeth are not involved in the mycosis. The stomach contains mushy 
digesting food. The mucosa is mottled pink, soft, digesting, at lower 
half submucosa is deep pink, a few small ecchymoses. From pylorus to 
ileum, serosa is deeply injected, edematous, mucosa swollen and edema- 
tous, deep pink, loosened in places, but translucent. Below this the 
mucous membrane becomes smooth, flat, pink-yellow. Lower ileum and 
colon contain rather firm fecal balls. Follicles nowhere prominent. 
The pancreas is small, soft, yellow-pink. The follicles of the mesentery 
are small, pink-gray and homogeneous. Smears from the broncho- 
pneumonia show a thread-like Gram-positive form and a few Gram- 
negative rods. Cultures from lung show Aspergillus fumigatus and 
Micrococcus albus. Nose too foul for culture. Histological section of 
lung shows the alveoli mostly open but the septa widened by congestion. 
Blood vessels are open and contain recent clots; one vessel near lesion 
below is thrombotic. The two large bronchi in section show catan'hal 
bronchitis and infiltrative peribronchitis of which the latter is more 
severe and advanced. Beside the larger is a necrotizing pneumonitis 
from which nearly all the architecture has disappeared. The exudate 
is chiefly mononuclear around the edges; centre no cellular identity. 
Another mononuclear process not connected with bronchus in section 
is found with an early necrosis. Streptothrix strands may be found in 
the bronchial exudate and near the margin of the necrotic patch. They 
do not grow in colonies however. The spleen shows general congestion 
without pigmentation. Follicles large, solidly lymphoid. Connective 
tissue about normal. The kidneys show marked congestion everywhere. 
Capsule and intrarenal fibrous tissues about normal. Very severe con- 
gestion which seems to have caused compression and granularity of 
the epithelium. 
The last case, judging by stained smears, is one of 
pure nasosinusitis from streptococci and streptothrices. 
Cultures were not tried because of the enormous bac- 
terial flora.
