RESUMO
In this preliminary study we have examined 12 healthy men aged between 20-60 years, by three specimens each. All the isolated could be assigned to genera by biochemical tests and gas-liquid chromatography. The results showed a 10(8)/g concentration of aerobe bacteria in faeces and a 10(10)/g concentration of anaerobe non sporing bacteria. The results of the count of Clostridia showed a variability among the examined individuals. The predominant groups of aerobes in the faeces were found to be E. coli and S. faecalis spp. and the predominant group of non sporing anaerobes were Bacteroides and Bificobacteria. These results were similar to the data obtained from foreign AA., showing the predominance of anaerobes in the faeces and particularly of Bacteroides.
