RESULTS
In the evaluation of the strains with the PFGE analysis, the 1st and 3 rd strains, and the 2 nd, 4 th and 5 th strains were identical. The 1st strain was isolated from the mobile phone of a healthcare provider working in the IMICU, and the 3 rd strain was isolated from the nose of the same worker. Similarly, the 2 nd strain was isolated from the mobile phone of a healthcare provider working in the IMICU, and the 4 th strain was isolated from the nose of the same worker. The 5 th strain, which was observed to be identical with the 2 nd and 4 th strains, was isolated from the mobile phone of another healthcare provider working in the IMICU. No similarity was observed between other strains ( Figure 1) .
