China Environmental Science, 2008, 28(1)：39~42 Abstract ：The occurrence of antibiotic-resistance E.coli to four classes of antibiotics including ampicillin, tetracycline, sulfonamide (sulfamethoxazole-trimethoprim) and levofloxacin in Wenyu river in Beijing was investigated by using membrane 3 7 filter method with E. coli chromogenic culture media. In Wenyu river basin, the total number of E. coli was 10 ~ 10 cell/L and the 6 number of antibiotic-resistance E. coli was 0~ 10 cell/L. The antibiotic-resistance rates to ampicillin, tetracycline, and sulfonamide were 10%~35%, 5%~25%, 10%~35% respectively; whil
