The evolution of clarithromycin, metronidazole and amoxycillin resistance in 246 Spanish Helicobacter pylori clinical isolates, obtained from paediatric patients during a 9 year period, was determined by an agar dilution technique. Clarithromycin resistance (MIC 1 mg/L) was 2.27% (IC95 0.05-12.02) in 1991-1993, 20.98% (IC95 12.72-31.46) in 1994-1996 and 28.33% (IC95 20.48-37.28) in 1997-1999 (P < 0.01). Metronidazole resistance (MIC 8 mg/L) was 7.14% (IC95 1.49-19.48) in 1991-1993, 20.25% (IC95 12.04-30.79) in 1994-1996 and 43.90% (IC95 32.95-55.30) in 1997-1999 (P < 0.01). Amoxycillin resistance was not found (all strains showed MICs < 2 mg/L).
采用琼脂稀释法测定了9年间从西班牙儿科患者中分离出的246株幽门螺杆菌临床分离株对克拉霉素、甲硝唑和阿莫西林的耐药性演变情况。1991 - 1993年克拉霉素耐药率(MIC≥1mg/L)为2.27%(95%置信区间0.05 - 12.02),1994 - 1996年为20.98%(95%置信区间12.72 - 31.46),1997 - 1999年为28.33%(95%置信区间20.48 - 37.28)(P < 0.01)。1991 - 1993年甲硝唑耐药率(MIC≥8mg/L)为7.14%(95%置信区间1.49 - 19.48),1994 - 1996年为20.25%(95%置信区间12.04 - 30.79),1997 - 1999年为43.90%(95%置信区间32.95 - 55.30)(P < 0.01)。未发现阿莫西林耐药情况(所有菌株MIC均<2mg/L)。
