Resume
Nous avons examiné au microscope électronique après coloration négative au cours de deux hivers successifs 110 selles d'enfants âgés de moins de 3 ans dont 88 étaient hospitalisés pour gastro-entérite infantile. Dans le groupe témoin, constitué de 22 enfants hospitalisés pour des motifs divers pour lesquels la coproculture était pratiquée à titre systématique, aucun virus n'a été mis en évidence tandis que les selles d'enfants atteints de gastro-entérite étaient riches en virions dans 31,8 % des cas. Dans 22,7 % des cas les virions observés étaient des Rotavirus, dans 9,1 % des cas il s'agissait de virus divers : Adénovirus, Astrovirus, Coronavirus.

Abstract
During two successive winters, faecal extracts from 110 children under 3 years of age were examined by electron microscopy with negative contrast. In a first group of 22 children hospitalised for various medical disorders, no virus particles were detected. In the second group of 88 children with acute gastroenteritis, we found viruses in 31,8 % of the faecal extracts, Rotavirus were detected in 22,7 % of the specimens and various particles (Adenovirus, Astrovirus, Coronavirus) in 9,1 % of the specimens.
Key-words: Infantile gastroenteritis, Rotavirus, Astrovirus, Coronavirus, Electron microscope
