Abstract

Most probable numbers of Vibrio cholerae and related vibrios were determined in Albufera Lake, Valencia, Spain, and in coastal waters under the influence of the lake discharges over the course of an annual cycle. The influence of temperature, kind of water, and characteristics of the different sampling sites on the numbers of vibrios recovered was evaluated. Maximum recovery of vibrios reached 10(3)/ml in both types of waters analyzed. V. cholerae numbers reached 10(3)/ml in the lake and 10(2) in one of the coastal sites. Frequently during the warm season, all vibrios isolated were identified as V. cholerae. Occasionally, no V. cholerae was recovered. The recovery of vibrios was significantly influenced by the temperature of the water and the type of water analyzed. Most of the V. cholerae isolates were included in Heiberg groups I and II, and nearly 50% of the strains used chitin as sole carbon source. Indole was not produced by 100% of the strains. All strains tested were non-O1 serovars.

摘要

在西班牙巴伦西亚的阿尔布费拉湖以及受该湖排放影响的沿海水域,对霍乱弧菌及相关弧菌的最可能数进行了为期一年的测定。评估了温度、水质类型以及不同采样点的特征对弧菌回收数量的影响。在所分析的两种水域中,弧菌的最大回收率均达到10³/ml。在湖中霍乱弧菌数量达到10³/ml,在一个沿海采样点达到10²/ml。在温暖季节,经常分离出的所有弧菌均被鉴定为霍乱弧菌。偶尔也未检测到霍乱弧菌。弧菌的回收率受到水温及所分析水质类型的显著影响。大多数霍乱弧菌分离株属于黑贝尔格I群和II群,近50%的菌株以几丁质作为唯一碳源。并非所有菌株都产生吲哚。所有测试菌株均为非O1血清型。
