The Interaction between Heterotrophic Bacteria and Coliform, Fecal Coliform, Fecal Streptococci Bacteria in the Water Supply Networks
BACKGROUND This study investigated the interaction between heterotrophic bacteria and coliform, fecal coliforms, fecal streptococci bacteria in water supply networks. METHODS This study was conducted during 2013 on water supply distribution network in Aq Qala City, Golestan Province, Northern Iran and standard methods were applied for microbiological analysis. The surface method was applied t...

متن کاملInteractions between heterotrophic plate count bacteria and coliform organisms.
Studies were initiated to investigate the interactions between heterotrophic plate count bacteria and coliform organisms. We used spiked samples to show that heterotrophic plate count bacteria could reduce coliform densities by more than 3 logs within 8 days. Some heterotrophic plate count bacteria were able to cause injury to the coliform population. A significant correlation (r = 0.66; P less...
متن کاملComparison of media for recovery of total coliform bacteria from chemically treated water.
Five broth media and two solid media were compared for their ability to quantitatively recover total coliform bacteria from chemically treated water. M-Endo LES and mT7 media were used in the membrane filter technique. Lauryl tryptose broth, lactose broth, presence-absence broth, lactose broth with twice the amount of lactose, and lauryl tryptose broth with twice the amount of sodium lauryl sul...
متن کاملPhenotypic characteristics of coliform and noncoliform bacteria from a public water supply compared with regional and national clinical species.
During the summer and fall of 1984, elevated total coliform counts were observed in the distribution system of a public water supply serving 350,000 people in south central Connecticut. As part of an investigation of possible health risks associated with the presence of bacteria in the water supply, bacterial isolates from the distribution system were compared with bacterial isolates of the sam...
