Section shows that the en-tire substance of the kidney is densely studded with these minute white gross pathological conditions were interpreted before nocardia wasfound as follows: An old tuberculous nodule in the right lung; acute miliarytuberculosis in the right lung and peritoneum; acute lobar pneumonia, affectingthe left lung; septic infarctions and pyemic abscesses of both lungs, heartmuscle, both kidneys, pancreas, mesenteric lymph nodes, and subcutaneousconnective tissue. The miliary tubercles of the right lung and peritoneumpresented the characteristic appearance of genuine tuberculosis. They wereminute, hard, gray, almost translucent nodules, while the granules in the kidneyswere of an opaque white or yeUowish-white color. _. Fig. 165.—Portion of kidney showing minute and large areas of infection. Microscopic Examination.—Smears from the abscess beneath theskin and on the surface of the kidneys were stained with methyl blue,carbol-fuchsin, and by Grams method. The smears resemble thosemade of tenacious sputum. There is a large amount of mucoid materialcontaining a considerable number of leukocytes. Occasionally irregu-larly curved, thread-shaped microorganisms are found. They varyconsiderably in length and thickness, and broken and apparentlydegenerating fragments are seen. The more slender threads are evenlystained, but some fragmentation or beading of the protoplasm cangenerally be observed. The thicker threads and broken fragmentsshow deeply stained globules and irregular bodies in a faintly visiblerod or thread-shaped covering. Some branching threads are observed,but more commonly they are not branching.
