Eperythrozoon ovis, a rickettsial parasite of erythrocytes, was found in anemic lambs maintained for reproductive endocrinology research. The parasite was identified in the blood films of 13 animals in the flock of 30. The sexes were infected equally (7/16 males versus 6/14 females). The relationship between the severity of the anemia and the presence of organisms in blood was statistically significant. One animal died with severe anemia. Light, scanning electron, and transmission electron microscopy of peripheral erythrocytes revealed an extracellular organism identified as E. ovis. These findings indicate that this parasite can cause disease in sheep and therefore may interfere with biomedical research.

D008855	Microscopy, Electron, Scanning	Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.

D009174	Mycoplasma	A genus of gram-negative, mostly facultatively anaerobic bacteria in the family MYCOPLASMATACEAE. The cells are bounded by a PLASMA MEMBRANE and lack a true CELL WALL. Its organisms are pathogens found on the MUCOUS MEMBRANES of humans, ANIMALS, and BIRDS.
