The incidence of Vibrio cholerae in shellfish, sediment, and waters of California, Oregon, and Washington was determined during the summer of 1984. Samples from 24 distinct estuaries were analyzed qualitatively. V. cholerae non-O1 was found in 23 estuaries and in 44.6% of the 529 samples examined. V. cholerae O1 Inaba was isolated from water samples in Morro Bay, Calif. Vibrio mimicus was found in 2.3% of the samples. Cholera enterotoxin was not found in cell-free filtrates of the 100 isolates tested in the Y-1 mouse adrenal cell assay, but heat-labile cytotoxic activity was observed with 3% of the isolates.
1984年夏季测定了加利福尼亚州、俄勒冈州和华盛顿州的贝类、沉积物及水体中霍乱弧菌的发生率。对来自24个不同河口的样本进行了定性分析。在23个河口以及所检测的529个样本中的44.6%发现了非O1群霍乱弧菌。从加利福尼亚州莫罗湾的水样中分离出了稻叶型O1群霍乱弧菌。在2.3%的样本中发现了拟态弧菌。在Y-1小鼠肾上腺细胞试验中对100株分离菌进行检测，在其无细胞滤液中未发现霍乱肠毒素，但3%的分离菌具有热不稳定细胞毒性活性。
