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).
