Microbiological Analysis of Hemodialysis Water in a Developing Country.

Microbiological control of hemodialysis fluid is important for the prevention of hemodialysis-associated illness. Bacterial populations inhabiting a distribution system for hemodialysis water were studied over a 4 month period in five hospitals (one in Tehran, and the others at Alborz). All the samples from the four hospitals at Alborz had colony counts of ≥100 CFU/ml, which at different points of sampling were higher than the maximum recommended values.
