The study of drug-resistant bacteria in the Tone River

耐药率依次为氨苄西林45.2%、头孢噻吩51.6%、头孢噻肟12.1%、头孢他啶5.4%、亚胺培南6.4%、庆大霉素1.9%、阿米卡星1.6%、氯霉素10.8%、四环素4.5%、环丙沙星1.3%。耐药性存在地域差异，城市地区耐药菌变异有增加的趋势。

In our results, the rate of prevalence of drug-resistant strains was as follows: ampicillin, 45.2%; cephalothin, 51.6%; cefotaxime, 12.1%; ceftazidime,5.4%; imipenem, 6.4%; gentamicin, 1.9%; amikacin, 1.6%; chloramphenicol, 10.8% ;tetracycline, 4.5%; ciprofloxacin, 1.3%. There was a local difference in drug resistance, and the variation of resistant bacteria tended to increase in an urban area.
