QT4 NOCARDIOSIS 
internal surface of the metacarpal and metatarsal regions, the fore- 
arms and thighs and rarely the neck. In chronic cases the lymphatic 
glands become swollen and painful. 
Morbid anatomy. The nodule swellings or cords rarely form cir- 
cumscribed abscesses but they frequently become pasty and fluctuate 
in certain places. It is said not to be common for swellings and 
suppurative processes to extend to the skin or to cause ulceration. 
When the swellings are opened they are found to contain a whitish, 
odorless, sebaceous appearing material of a creamy consistency. The 
openings rarely suppurate but heal quite promptly. In some cases 
the lungs, liver, spleen and internal glands are sprinkled with nodules 
the central part of which have undergone caseous or purulent changes. 
Diagnosis. This disease must not be confused with epizodtic 
lymphangitis, skin tuberculosis or skin actinomycosis.

NOCARDIOSIS 
History. In 1910 Burnett described a pneumonia in cattle due to a 
new species of Nocardia (Streptothrix) which he designated Actino- 
myces pulmonalis. It was found in two animals that had been 
slaughtered under suspicion of tuberculosis but neither of them had 
reacted to tuberculin. The lesions found were unlike those of tuber- 
culosis and upon more careful examination were found to be due to an 
organism resembling Sanfelici’s second group, type Streptothrix flava, 
though differing from it in the color of its growth on agar. 
Etiology. Nocardia pulmonalis appears in the tissues as short and 
longer filaments, resembling the mycelium of some fungi except that 
they are more slender. They exist in the tissue as thread-like fila- 
ments which become more or less matted or clumped together. They 
grow in bouillon and milk, forming colonies on the sides of the tube. 
The growth on agar after two days resembles that of boiled sago and 
adheres to the agar surface. On potato the growth is more luxuriant. 
On gelatin it develops a whitish growth with branched filaments
