RESULTS
In the pre-experiment (5 subjects), when the cfu of microorganism
attached to gloves after defecation cultured aerobically with TSA and
anaerobically with GAM agar were compared, all five individuals had more
cfu with TSA. Therefore, in this experiment, anaerobic culture with GAM
agar was not performed, and only aerobic culture with TSA was performed.
Table 1 shows the number of microbe attached to gloves after defecation
with and without the use of bidets. The average ± standard deviation of
the colony forming units (cfu) attached to gloves after defecation
without using a bidet was 39,449.3 ± 77,768.3 / glove, however, it was
4,146.9 ± 11,427.7 / glove when a bidet was used. The amount of microbe
adhering to the glove after defecation was significantly reduced when a
bidet was used (p < 0.0001, Wilcoxon singed-rank test)
(Table 1).
