Abstract
A wild type rabbit was infected orally with cell culture-grownEncephalitozoon cuniculi. Twelve weeks after infection the rabbit was killed and blocks of kidney tissue were fixed for histology and electron microscopy.E. cuniculi were observed within kidney collecting tubule cells. The ultrastructure and development ofE. cuniculi in these cells was similar to that described in cultured cells and peritoneal macrophages.
