Phenotypic and genotypic detection of Aeromonas spp. isolated from drinking water

Abstract

Contamination of drinking-water is a significant concern for public health throughout the world. Microbial hazards make the largest contribution to waterborne disease in developed and developing countries. Biofilm-producing bacteria were identified by the Congo Red Agar (CRA) method we obtained isolated of Aeromonas spp. formed Biofilm. the antibiotic resistance screening test to a number of antibiotics on Aeromonas spp. isolates. The results revealed that isolates of Aeromonas spp. have high resistance (100%) to Amoxicillin , Vancomycin and Cefoxitin. Whereas some isolates of Aeromonas spp. observed moderate resistance to Imipenem and Erythromycin. PCR to detected presence of fimH and papC genes in Aeromonas spp. that isolated from drinking water contain fimH gene and contain pap C. fimH was an important factor in cell control and bacterial persistence under stress conditions, and it contributed to virulence through a variety of mechanisms.
