[The effects of chlorine disinfection on the resistance of E. coli in water].
Under defined conditions E. coli were subjected to repeated chlorine disinfections 10 times. The survival E. coli at 30 s (A10), and the survival E. coli at 10 min (B10) had no difference in resistance to chlorine to their original strain (A0). However, the compound E. coli (C10) survived at various contact time showed an increased resistance than their original strain (A10), the degree of increased resistance varying with different conditions of disinfection. E. coli C1(0) lost its increased resistance after it has been passaged 10 times on nutrient agar.
