The production of ascitic fluid and splenomegaly on intraperitoneal injection in weanlings was used as a test for microsporidia after introduction by other routes and in other loci. Oral and cerebral administration was followed only by enlarged spleens which reproduced the ascitic response on passage. Microsporidia were demonstrable by phase microscopy in all fluids. Positive findings were also obtained with liver, kidney, brain, lungs, blood, and urine. Intramuscular and intranasal injection were occasionally followed by ascites, but splenomegaly again predominated. The results of contact experiments indicated that the organisms were not readily communicable either in weanlings or nurslings. Relation of the microsporidian to Encephalitozoon cuniculi (Nosema cuniculi Lainson et al.) is discussed.
在断奶仔猪经其他途径和在其他部位接种后，通过腹腔注射产生腹水和脾肿大作为微孢子虫的一项检测。口服和脑内给药后仅出现脾脏肿大，传代时再现腹水反应。通过相差显微镜在所有液体中均可检测到微孢子虫。在肝脏、肾脏、脑、肺、血液和尿液中也获得了阳性结果。肌肉注射和鼻内注射偶尔会导致腹水，但脾肿大再次占主导。接触实验结果表明，这些生物体在断奶仔猪或哺乳仔猪中不易传播。讨论了微孢子虫与兔脑原虫（兔鼻疽原虫Lainson等人）的关系。
