Visna virus infection of American lambs. 1974

O Narayan, and A M Silverstein, and D Price, and R T Johnson

Random-bred fetal and 4-week-old American lambs, inoculated intracerebrally with visna virus, developed a persistent infection in the brain and sometimes in the lung. The pathologic changes present in these lambs were similar to the early lesions of visna in Icelandic sheep, thus providing a possible model for the study of virus-induced demyelinating disease.

UI	MeSH Term	Description	Entries
D007055	Iceland	A country in northern Europe, an island between the Greenland Sea and the North Atlantic Ocean, northwest of the United Kingdom. The capital is Reykjavik.
D009656	North America	The northern continent of the Western Hemisphere, extending northward from the Colombia-Panama border and including CENTRAL AMERICA, MEXICO, Caribbean area, the UNITED STATES, CANADA and GREENLAND. The term often refers more narrowly to MEXICO, continental UNITED STATES, AND CANADA.	Northern America
D011020	Pneumonia, Pneumocystis	A pulmonary disease in humans occurring in immunodeficient or malnourished patients or infants, characterized by DYSPNEA, tachypnea, and HYPOXEMIA. Pneumocystis pneumonia is a frequently seen opportunistic infection in AIDS. It is caused by the fungus PNEUMOCYSTIS JIROVECII. The disease is also found in other MAMMALS where it is caused by related species of Pneumocystis.

D003588	Cytopathogenic Effect, Viral	Visible morphologic changes in cells infected with viruses. It includes shutdown of cellular RNA and protein synthesis, cell fusion, release of lysosomal enzymes, changes in cell membrane permeability, diffuse changes in intracellular structures, presence of viral inclusion bodies, and chromosomal aberrations. It excludes malignant transformation, which is CELL TRANSFORMATION, VIRAL. Viral cytopathogenic effects provide a valuable method for identifying and classifying the infecting viruses.
