Abstract—A total of 10 motile Aeromonas strains were detected in water samples. These strains were identified by conventional microbiological techniques as Aeromonas hydrophila. Genetic diversity by PCR-RFLP analysis with Universal 16s rRNA primers and plasmid profiles were carried out on ten A. hydrophila isolates obtained from water samples. Antimicrobial sensitivity patterns of the Aeromonas isolates revealed that 100% were sensitive to gentamicin, 80% to sulphamethoxazole–trimethoprim, 70% to chloramphincol, 50% to ciprofloxacin, 40% to neomycin, (30% to tetracycline, 20% to streptomycin and 10% to erythromycin. all were resistant to novobiocin and bacitracin.
Index Terms—Aeromonas hydrophila, aquatic environment, PCR-RFLP analysis of 16s rRNA, plasmid profiles.
