Abstract (in Japanese) (See Japanese page) 
(in English) The cleanliness of the pure water for dilution of the dialysis fluid has closely related to the pollution of the heterotrophic bacteria in the process of manufacture. There for, control against these bacteria have become an important problem. On the other hand, there is a clear correlation between microbial pollution of the water treatment process and the biofilm formation in it. The biofilm formation in hemodialysis line process,has not been studied. In this report, we conducted the experiment biofilm formation using heterotrophic bacteria isolated for clinical sources. And we also reported experimental system that it reproduce the biofilm formation and can be assay the biofilm dose. Furthermore, we examined the effectiveness of disinfectant treatment of the manufacturing process for biofilm using this experimental system. As a result, a biofilm of heterotrophic bacteria showed high resistance against the disinfectant treatment.
