Phenotypic characteristics of Escherichia coli isolates in patients with urinary tract infections vary from region to region. Therefore, studying the phenotypic properties of the bacterium is very important.</p><p><strong>Materials and Methods:</strong> In the current study, 100 strains of <em>Escherichia coli</em> were detected from urine samples of patients with urinary tract infections in Mazandaran province, Babol. This study aimed to investigate the properties of metallic green sheen, beta hemolysis, and Ortho-nitrophenyl-β-D-galactopyranoside (ONPG) test of Escherichia coli.</p><p><strong>Results:</strong> The most common bacterium isolated from urinary tract infections was <em>E. coli</em> (68.02%). In the present study, the properties of beta hemolysis, metallic green sheen, and ONPG in uropathogenic <em>E. coli</em> were 1, 80, and 100%, respectively.</p><p><strong>Conclusion:</strong> The results of this study showed that 20% of E. coli strains lacked metallic green sheen, which should be identified through the IMViC test and other biochemical tests.</p> ER -
