JOURNAL OF PURE AND APPLIED MICROBIOLOGY, June 2015. Vol. 9(2), p. 1007-1013 Predictive Parameters of Heterotroph Plate CountBacteria Amplification in Hospital Water Lines G. Ghanizadeh, A. Mirmohammadlou and D. Esmaeli This research illustrates microbial instability of water from point of heterotrophic bacteria (HPC) amplification in accordance with residual chlorine, pH, temperature, dissolved oxygen (DO) and alkalinity (Alk) in hospital water. Hundred-fifty samples were collected from hot and cold tap water systems. Residual chlorine, pH and temperature were determined promptly in place; HPC was cultured on R2A culture media and spread plate method. DOand Alk was determined by Winkler and photometric methods, respectively. HPC was detected in 96% of samples therefor fifty-two percent had higher than the recommended standards and HPC density in samples been 947±998 CFU/ml. The highest contamination was detected in cooling systems, gynecological, NICU and sonography ward (1500-2 وبلاگ مهندس علی میرمحمدلو...
