Comments P.96 3rd paragraph: "The faecal microflora of children appears to resemble the adult flora by the age of one year. The numbers of aerobic microorganisms have decreased and anaerobes, particularly Bacteroides and Lactobacillus, become predominant in the faecal flora (Ellis-Pregler et al. 1975). At the age of 4-8 years, the microflora resembles that of adults. The same numbers of lactobacilli are seen as in adults and the ratio of anaerobic bacteria to aerobic bacteria is 1000: 1."
