| Summary: | Background: Due to the widespread different pathogenic strains, Escherichia coli lead many severe to normal diseases worldwide. Finding the relation of clones with genomic content and clinical features is a key point to recognize the high potential-invasive strains. Specific virulence factors include adhesions, invasions, toxins, and capsule are the main determinants of pathogenic factors of E. coli strains. Methods: From Jun 2014 to Jun 2016, E. coli isolates recovered using standard bacteriological methods from wastewater sources in different hospitals in Tehran, Iran, were monitored to recognize the virulence genes by polymerase chain reaction (PCR) assay. Results: The high and low presences of virulence factors were fimH, 76% and afa, 13%, respectively. Conclusion: The results indicated the potential pathogenicity of E. coli strains circulating in hospital wastewaters in Tehran, Iran. |
