摘　　要：霍乱弧菌的检测。采用常规的浓缩蛋白胨水增菌法检出率低,容易造成假阴性。该法采用碳酸钠和硫酸亚铁化学沉淀吸附法。沉淀剂将水中的霍乱弧菌沉淀聚集于水体下层,经过反复试验,检出率提高1倍以上。对饮用水源的污染监测起到积极主动作用。方法易于推广。Positive rate of EL TOR Vibrio cholerae by usual proliferation method was low, determination error of false negative sample was easy to occur. Precipitation-adsorption proliferation method using sodium carbonate and ferrous sulfate was studied in this article. Precipitant could acumulate EL TOR Vibrio cholerae in water to the precipitate and positive rate could be 2 times as usual. This method was very helpful for inspection of drinking water source pollution.
