    Notes: Abstract The ability to obtain iron of 14 isolates of Vibrio damsela with different degrees of virulence for mice and turbot (Scophthalmus maximus) has been evaluated in artificial and natural iron-restricted environments. All strains were capable of utilizing haemoglobin (Hb) and ferric ammonium citrate (FAC) as the sole iron sources in vitro. However, only virulent V. damsela strains were able to resist the bacterioslatic and bactericidal effects of human and turbot sera, their growth being enhanced by the addition of Hb and FAC. The inhibitory effect of these sera on the growth of the non-pathogenic strain (ATCC 35083), however, was reversed by heat treatment (56°C for 60 min). The role of iron-availability on the virulence was investigated in iron-overloaded animals. The iron-treatment before the infection resulted in a significant reduction in the LD50 of virulent strains. This fact demonstrates a positive correlation between iron availability in host fluids and degree of virulence in the species Vibrio damsela.

    Comparison of outer membrane protein profiles of Vibrio vulnificus biotypes 1 and 2 (1993)

    Notes: Abstract The outer membrane proteins of 17 Vibrio vulnificus biotype 2 strains from Japanese and European cels, and 12 biotype 1 strains from clinical and environmental sources have been compared. The overall profile in both biotypes was similar, and a major protein band of molecular mass 36 kDa was detected in the majority of the strain. Differences in the minor bands allowed differentiation of strains from different origins, suggesting that outer membrane protein profiles could be useful as epidemiological markers in the species V. vulnificus. Immunoblotting with antisera to whole cells of selected strains of biotypes 1 and 2 showed a strong antigenic response to outer membrane proteins 66, 60, 48, 46 and 44 kDa; these were common to all strains examined, independent of their biotypes and origins. These results demonstrate the presence of antigenically related outer membrane proteins in both biotypes of V. vulnificus.
