Objective: This study was performed to assess bacterial distribution concerned in sanitation management of public lavatory in Seoul. Methods: In this research, bacteriological investigation on public lavatory was accomplished for bidet water, bidet nozzle, washbowl and lavatory stool in the 50 public facilities such as public institutions, subway stations, cinema, department stores, large-scale buildings and hospitals amount to 374 specimens. Results: The geometric mean of colony forming unit(CFU) in total aerobic colony count were analyzed as follows; 5.2×102/100 cm2 on lavatory stool, 7.2×103/ea on bidet nozzle, 7.8×103/ea on center ring of washbowl, 1.4×10/mL in bidet water (ml) and 7.0/ea on doorknob. Opportunistically pathogenic germs such as Staphylococcus aureus, Escherichia coli, Enterobacter cloacae, Pseudomonas aeruginosa were isolated in 3.7%, 5.9%, 3.2% and 1.9% of total specimens, respectively. Conclusion: The result of this study shows that there were some facilities where the pathogenic germs were detected to may cause urological infection. And the CFU of general bacteria as the representative indicator of disinfection and lavatory cleaning were high enough to imply the improvement of sanitation management of public lavatories should be contrived.
