| surface and virulence properties of environmental vibrio cholerae non-o1 from albufera lake (valencia, spain). | a total of 140 environmental vibrio cholerae non-o1 isolates, together with several culture collection strains from both environmental and clinical sources, were studied in relation to hemagglutination, surface hydrophobicity, and the enzymatic, hemolytic, cytotoxic, and enterotoxic activities of their extracellular products. a total of 78 and 62% of the strains produced hemagglutinins and exohemagglutinins, respectively. four different hemagglutinating and two exohemagglutinating activities wer ... | 1990 | 1692675 |
| [presence of salmonella in the northwest shore of the l'albufera de valencia]. | for the purpose of ascertaining the amount of pollution reaching the large salt lagoon in valencia from its northwest side, 19 river-beds flowing into it have been studied. for each sample, the presence of markers indicating fecal pollution and the presence or absence of pathogens; salmonella, vibrio cholerae and shigella have been evaluated. for each river-bed, a fecal pollution index has been calculated, this index revealing a positive correlation (p = 0.03) with the isolating of salmonella. s ... | 1990 | 2131632 |
| cell envelope proteins of environmental vibrio cholerae non o1 isolates from albufera lake (valencia, spain) influence of some factors on omp expression. | the cell envelope proteins of 89 environmental vibrio cholerae non o1 strains isolated from lake and coastal waters near valencia, spain, and six vibrio cholerae strains from culture collections were analyzed by sodium dodecyl sulphate-polyacrylamide gel electrophoresis. considerable heterogeneity was found in the major proteins of the environmental non-o1 strains, but bands between 25,000 and 48,000 daltons were observed in the majority of the strains. estimated relative mobilities of the total ... | 1989 | 2604845 |
| the annual cycle of zooplankton-associated vibrio cholerae and related vibrios in albufera lake and its coastal surrounding waters (valencia, spain). | most probable numbers of zooplankton-associated vibrio spp. and v. cholerae were determined in albufera lake, spain, and in its coastal receiving waters throughout a year. highest counts of 10(5) bacterial cells/g of plankton were associated to high temperatures and were also related to the kind of water. all isolates were non-01 serovars, and most belonged to heiberg groups i and ii. | 1988 | 3271065 |
| incidence of vibrio cholerae and related vibrios in a coastal lagoon and seawater influenced by lake discharges along an annual cycle. | 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) i ... | 1985 | 4051487 |
