Mezrioui, Kh. Oufdou] The abundance and antibiotic resistance of non-O1 Vibrio cholerae strains were studied in wastewater before and after treatment in stabilization ponds in an arid Mediterranean climate. The seasonal abundance of non-O1 Vibrio cholerae was the inverse of those of fecal coliforms, with high densities in hot periods and low densities in cold periods. Although the stabilization pond presents a good efficiency in removing fecal coliforms (97.97%), this treatment system did not produce any significant reduction in non-O1 V. cholerae abundances between the inflow and outflow stations. Among the 240 non-O1 V. cholerae strains isolated before and after treatment in the stabilization ponds, 89 (37.1%) isolates were resistant to at least one of 14 tested antibiotics. The levels of antibiotic resistance at the inflow and outflow points of the system were respectively 40 and 34%. High ampicillin, amoxicillin and mezlocillin resistance was observed at all sampling points, followed by resistance to cefalexin, cefoperazone and amikacin. Antibiotic resistance can be transferred from non-O1 V. cholerae to other members of the Enterobacteriaceae family such as Escherichia coli K12. Transfer frequencies in nutrient broth and filtered wastewater were 3 × 10−5 and 2 × 10−8, respectively. © 1996 Federation of European Microbiological Societies. Published by Elsevier Science B.V.
