为了解三峡库区长江水非Ｏ_１群霍乱弧菌Ｌ型的流行病学状况，１９９４～１９９８年作者在三峡库区选三地取长江水同时进行非 Ｏ_１群霍乱弧菌与非Ｏ_１群霍乱弧菌Ｌ 型的检测（培养温度与采样时水温一致）．结果发现非 Ｏ_１群霍乱弧菌Ｌ型冬天阳性检出率较高，夏天阳性检山率较低（Ｐ＜０．０１）。但各月份总阳性率无明显差异（Ｐ＞０．１）。非Ｏ_１群霍乱弧菌Ｌ型返祖记回复后证实为非Ｏ_１群霍乱弧菌。表明非Ｏ_１群霍乱弧菌Ｌ型为非Ｏ_１群霍乱弧菌越冬的一种重要形式．在卫生监督中，应加强对非Ｏ_１群霍乱弧菌Ｌ 型的监测．
In order to understand the epidemiological status of non-O_1 group Vibrio cholerae L-form in Yangtze River water in the Three Gorges Reservoir Area, from 1994 to 1998, L-type bacteria detection (incubation temperature and sampling the same water temperature). The results showed that the detection rate of L type winter positive Vibrio cholerae was higher than that of non-O_1 group Vibrio cholerae, and the positive rate of summer mountain detection was lower (P <0.01). However, there was no significant difference in the total positive rates between months (P> 0.1). Non-O_1 group Vibrio cholerae L-type progenitor returned to confirm the non-O_1 group of Vibrio cholerae. It shows that non-O_1 group Vibrio cholerae L-form is an important form of non-O_1 Vibrio cholerae overwintering. In health surveillance, surveillance of L-type Vibrio cholerae non-O_1 group should be strengthened.
