[Application of immunoelectron microscopy to the detection of viruses in a water medium].

Adenoviruses were immersed in demineralyzed and deionized water for 5 days. The water was subsequently analyzed by Immuno-Electron-Microscopy for detection of viral particles. An attempt of quantation was also made on control, untreated particles. Viruses dispersed in water can be detected by the technique employed but quantitation is limited by the heterogeneous dispersion of the particles on the grids.
