| Outline of Final Research Achievements |
We modified the beads extraction method and developed a highly sensitive method for the detection of Bacillus cereus spores which contaminate hand towels. We applied this method to hand towels regarded as clean of A hospital and found out a substantial degree of B. cereus contamination of the towels. We also performed an adherence test of B. cereus spores to various fabrics in order to find materials for hospital linens which are resistant to spore adherence. As a result, B. cereus spores adhered highly to wool, silk, and acryl fiber, whereas only slightly to cotton and rayon. We also found that the contexture of clothes affected the adherence of spores. Based on these results, we started developing of safe patient clothes.
We also investigated the colonization of B. cereus spores on the forearm skin of healthy adults and found that 20 % of them carried B. cereus spores on their skin. Among these B. cereus isolates, we found a highly resistant strain which needs special attention.
