The Occurrence of Class 1 Integron among Escherichia Coli Strains Isolated from Surface Water Sources in Alborz Province

Article excerpt

Background: E. coli is considered as one of the most im- portant causes of bacterial pathogenes transmitted via water and food. The aim of this study was to investigate the occur- rence of E. coli strains carrying class 1 integron isolated from different water sources in Alborz province.

Methods: This study was carried out in 2013 in which all E. coli strains isolated from different water sources in Alborz province were subjected. E. coli strains were detected and identified using standard microbiological and biochemical tests. Then, the strains were subjected for presence of class 1 integron by PCR using specific primers targeting int1.The PCR amplicons were visualized after electrophoresis and stained with ethidium bromide.

Results: Ninety nine E. coli strains were isolated and includ- ed in the study. The PCR results showed that 26% of the strains harbored integron class 1 gene. Most of bacterial strains harboring int1 were multi drug resistant. …
