Thus the skin, intestinal, and pulmonary nodules may be due to secondary distribution of the parasite. The micro-organism apparently lives for a con- siderable period of time in the tissues, because in the older areas of necrosis there are myriads of parasites all staining well. The mode of infection and portal of entry are unknown. The parasite has neither been cultivated nor transmitted by inoculation. Believing it to be a new parasite, DarUng has suggested that it be called Histoplasma Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original McFarland, Joseph, 1868-.
