Twenty healthy adult volunteers (divided into two groups) were given with 100 mL of acidophilus milk, twice a day, containing $1{\times}10^8\;cfu/mL$ of Lactobacillus acidophilus SNUL 01 or SNUL 02 originated from healthy Korean adults. The floral changes of lactobacilli, Escherichia coli, and Clostridium perfringens surviving in the feces as well as the pH of the fecal material have been studied for three weeks. Initial pH of the fecal samples before taking acidophilus milk were about pH 7 and it has been decreased to about pH 5 when the acidophilus milk was given. Population of fecal lactobacilli increased from about $10^7\;cfu/g\;to\;10^8\;cfu/g$ of fecal material after 4 days of acidophilus milk intake and the high population of lactobacilli was maintained up to 21 days. Viable cells of the fecal E. coli and C. perfringens have been decreased from about $10^7{\sim}10^8\;cfu/g\;and\;10^5{\sim}10^6\;cfu/g\;to\;10^6\;cfu/g\;and\;10^3\;cfu/g$ of fecal material after 21 days, respectively. In conclusion, continuous intake of acidophilus milk made with L. acidophilus SNUL 01 and SNUL 02 helped maintaining normal intestinal microflora, suppress harmful microorganisms.
