In these, and also in the lungs and pericardium small hemorrhages, and in some cases acute catarrh of the stomach and duodenum, with bloody contents in the intestines may be found, and in many cases also general icterus. The changes are generally less pronounced in very acute cases, while in chronic cases icterus is frequently absent, on the other hand a severe anemia is present. Piroplasma may be demonstrated in great numbers, especially in the kidneys and in the spleen. Symptoms. After an incubation of 7 to 10 days, a rise of the body temperature which inside of 2-3 days reaches 40°-43° C, and which is associated with languor, is observed in the acute cases as a first symptom. The visible mucous membranes appear at first a pale red, later cyanotic, and in about half of the cases also icteric. The pulse and the respiration are accelerated, the latter is moreover very labored- and panting. The patients re- fuse food, but drink a great deal. They move listlessly and stagger, and towards the end they can scarcely stand on their feet. The urine contains albumen from the onset, and in some of the cases up to 3%% hemoglobin, sometimes also bile pig- ments; for this reason it shows a more or less intense red coloration with a greenish hue. Ac- cording to Maignon the quantity of urea in- creases at each febrile attack (up to 95 gm. per liter of urine), and sugar also appears in the urine. The blood is pale red, the blood serum also reddish or greenish-red in color. The number of erythrocytes diminishes to 1/2 to 1/3 of the nor- mal or even more, while the leucocytes appear to be increased. Piro- plasma are found at first exclusively in the red blood corpuscles, later also in the blood plasma. In the later course of the disease their number increases, so that finally even 30% of the erythrocytes may be infested with them.
