title: Isolation of Non-O1 Vibrio cholerae Serovars from Oregon Coastal Environments.
abstract: Water, sediment, and shellfish from three Oregon estuaries were cultured for pathogenic Vibrio species. Non-O1 serovars of V. cholerae were the most common pathogenic Vibrio species recovered. Non-O1 V. cholerae were isolated from all three estuaries sampled, covering an area of about 170 miles along the Oregon coast. Non-O1 V. cholerae were isolated from water and sediment, but not shellfish, at temperatures ranging from 11 to 19 degrees C and salinities of 2.3 to 26 per thousand. Sixteen isolates representing 12 different non-O1 serovars were identified, while four non-O1 V. cholerae isolates failed to react with any of the 54 antisera tested. These results indicate that non-O1 V. cholerae serovars can be found over a large geographic area and under a variety of environmental conditions. These organisms are apparently an autochthonous component of these estuarine microbial communities.
