Abstract

|
Length of lag-phase period and rapidity of multiplication of the bacterial speciese in the given host tissues were known to result significant influences in establishing infection state. To investigate the mode of bacterial multiplication in the Korean female urines, bladder urines of 50 women were collected aseptically by catheterization and into the urines, after pH determination, 20 hr. broth cultures of E. coli and staph. Aureus were inoculated. After aerobic incubation at 37°C. of 1, 2, 3, 5, and 8 hours, viable units of the organisms in the urines were enumerated by pour-plate technique.
Results of the observation were summarized as follows:
1) Both the colon bacillus and staphylococcus showed rapid growth in the urines. However, the lag-phase in multiplication of colon bacillus in the urines appeared to be shorter than that of staphylococus.
2) Differences of urinary pH showed little influences on the rapidity of multiplication of colon bacillus, but much noticial influences on the rapidly of multiplication of staphylococus.
3) Colon bacillus appeared to grow more or less faster in the urines of women below 29 year old than in the urines of women over 30 year old. Staphylo coccus appeared to grow faster in the urines of women over 30 year old than in the urines of women below 29 year old.
4) Both the colon bacillus and staphylococcus seemed to grow faster in the urines of pregnant women.
