Intranuclear inclusion-bearing cells in urinary sediment with virus particles demonstrated by electron microscopy.

Further observations on inclusion-bearing cells in urinary sediment in infectious diseases.

A study of the cytology of the urinary sediment in 43 patients with known viral diseases has revealed a variety of inclusion-bearing cells in 28.The morphology of the cells suggest that the changes recorded may be due to the viral infections, at least in some instances, bearing in mind the findings of workers quoted in our 1964 report that cellular changes very similar to those induced by virus...

Detection of virus particles by electron microscopy with polyacrylamide hydrogel.

The use of lyphogel to concentrate the number of virus particles in specimens for electron microscopic examination was studied in parallel with ultracentrifugation. One hundred faecal and urine samples were compared. Both methods had a similar sensitivity. Lyphogel was economical, simple, and rapid in use; in contrast to ultracentrifugation, it required relatively little material. The procedure...

Immunogold Labeling of Cultured Cells and Virus Particles for Electron Microscopy and Cryo-Electron Microscopy Applications

Cryo-electron microscopy (cryo-EM) and cryo-electron tomography (cryo-ET) were first realized in the early 1980s [1] and mid-1990s [2, 3]. Since then both methods have quickly become a powerful tools in structural biology. The major advantage is that they allow for the acquisition of images of biological specimens persevered in their native state after they are plunge-frozen onto carbon-coated ...

Human papovavirus in Papanicolaou smears of urinary sediment detected by transmission electron microscopy.

A technique is described whereby inclusion-bearing cells identified by light microscopy in stained smears of urinary sediment were reprocessed for examination in the electron microscope. The nuclei of the abnormal cells were found to contain numerous virus particles, 35 nm in diameter, which morphologically resembled papovaviruses. The technique was applied in this case to identify further the ...
