[Coronavirus and "astrovirus" observed in stools of children with gastroenteritis (author's transl)]. / Coronavirus et "astrovirus" observés dans les selles d'enfants atteints de gastro-entérites.

In a year's survey (December 1976-November 1977) of 190 children admitted to hospital with acute gastroenteritis, an "aetiological" agent was found in stools by electron microscopy in 41% of cases. Rotavirus were found in 34% of patients. We also found Coronavirus-like particles and Astrovirus-like particles in 25 and 5 stools, respectively. Improvements are awaited to demonstrate the responsibility of these virus in gastroenteritis.

[Detection of small amounts of viruses (enteroviruses) in drinking water (author's transl)]. / Méthode de recherche de faibles quantités de virus dans l'eau de consommation.

A simple detection method of enteroviruses and adenoviruses in drinking water has been performed, using adsorption-elution on to cellulose nitrate membranes. Average of enteroviruses recovering is varying from 23 to 80% when 30 liters of water containing 60 PFU are monitored. Only 10% of adenoviruses are recovered in the same conditions. This method allowed us to detect 12 PFU of enteroviruses in 120 liters of water. Recovering of 1 PFU in 10 liters when examining more than 100 liters is reproducible.
