| Outline of Final Research Achievements |
Our previous study into assessing hospital cleanliness in Japan by two common methods, ATP bioluminescence and the stamp agar method. Although a weak correlation was found between ATP-based assessments and stamp-based assessments, fluctuations by day were observed in those numbers, and the error bars were large. Therefore, to search for these factors, we used next generation sequencing to survey the microbial community membership of each sample from each hospital. The three hospitals were of different sizes, and we tested for inter-hospital differences in microbial community structure.We surveyed the microbial diversity in each of 50 environmental samples from three hospitals of different sizes. Although taxonomic diversity differed between hospitals A and B, intestinal bacteria were particularly overrepresented in hospital C. These results suggest that bacterial flora may be related to factors influencing the level of cleanliness within a hospital.
