Survival of E. coli O157:H12 in creek sediments after inoculation and re-inoculation

摘要: This work tested the hypothesis that E. coli survival after streambed sediment inoculation does not differ significantly from in same re-inoculation. The O157:H12 survived two sediments with markedly different particle size distributions and organic matter contents one-month-long experiments flow-through chambers at 14°C 23°C. The inactivation rates re-inoculation were smaller than inoculation; differences significant (P < 0.1) of four experiments. study suggests was able to adapt environment so its improved.
