为了解诺氟沙星在环境中残留对土壤细菌的影响，在诺氟沙星作用于土壤后第35天对纯培养法分离的土壤细菌进行计数，并对土壤细菌进行抗菌药物敏感性试验。结果表明，添加药物组的细菌总数均低于对照组，且药物浓度越高，细菌数量越少；在供试的20种抗茵药中，诺氟沙星敏感菌对其中18种药物的敏感性与诺氟沙星耐药菌差异不显著（P〉O．05）。

Abstract： The experiment was aimed to investigate the effects of NOR （norfloxacin） on the quantity and dnlg-resistanee of bacteria isolated from soil. After the soils were treated with NOR for 35 days, bacteria isolated from soil samples were cultured on isolation media, and their antimicrobial susceptibilities were examined to study the effect of NOR onsoilbaeteria. The： resutts sh0wCd that the counts of soil among 6 treatment groups. The total bacteri; counts of treated groups were less than those of CK, and they were decreased with the increasing c0ncentration of NOR i, soil. The susceptlbiltles of NOR2sensltive bacteria to 18 kinds bf antimicrobial agents among 20 kinds of antiseptic wet, not significantly distinguished from that of NOR＇resistant bacteria （p〉0.05）
