ABSTRACT
OBJECTIVE:
Although the incidence in France of V. cholerae non-O1/non-O139 infection in man has increased since 1996, it remains low (7 cases in 1999). After the death in 1994 of an immunodepressed patient presenting a skin lesion showing superinfection by a strain of non-O1/non-O139 V. cholerae following exposure to seawater, we examined 22 samples of sea-water collected from 20 French coastal areas (Mediterranean coast).METHODS:
The sea-water samples were filtered and enriched with alkaline peptone water (APW), and the strains of Vibrio were isolated on TCBS, SS and BCP media and identified using the API 20 E system (bioMérieux, France).RESULTS:
We isolated 6 strains belonging to 3 species of Vibrio 2 V. cholerae (non-O1/non-O139), 3 V. parahaemolyticus and 1 V. alginolyticus. One of the V. cholerae strains was isolated from sea-water sampled at the coastal town in which the patient had been staying. The seawater strains exhibited high sensitivity (MIC determined by agar dilution) to the following antibiotics aminoglycosides, tetracyclines, azithromycin, cotrimoxazole, rifampicin and fluoroquinolones. The beta-lactams were very active against strains of V. cholerae isolated from seawater, while the strain isolated from this patient presented a new carbenicillinase (CARB-6) recently described.CONCLUSION:
The presence of Vibrio in seawater along the French coast-line constitutes a risk for immunocompromised patients, and the severity of Vibrio infections warrants improved monitoring both of these organisms and of the marine environment. In addition, awareness on the part of doctors would allow patients at risk to be warned against these dangers.
