The study has been aimed at demonstrating the main role of viruses in the aetiology of acute gastroenteritis in children less than five years old. All children (n=832) were tested by faecal culture, latex agglutination and electron microscopy.
A bacterial aetiology was found in 2.6% children and bacterial-viral co-infection was found in 17.6% patients). The most frequent causative agents of gastroenteritis in children were viruses (74.5% patients.
The main causes of viral gastroenteritis were rotaviruses, followed by caliciviruses, coronaviruses, adenoviruses and astroviruses. Dual viral infections were detected with rotavirus-calicivirus co-infection being the most common.
Electron microscopy proved to be a more sensitive method in comparison with the latex agglutination test for the diagnosis of rotaviruses and adenoviruses. The major role of viruses in diarrhoeal diseases among children under 5 years of age in the Czech Republic has been confirmed.
