ABSTRACT

Objetive: To introduce in the clinical diagnosis of urinary infections the biotyping strains of Escherichia coli identified in urine samples.
Materials and Methods: A retrospective observational study was conducted during the period from October 2012 to September 2013, at “Juan Manuel Márquez”. Pediatric Teaching Hospital The work included 539 strains of Escherichia coli isolated from urine samples obtained from patients suspected of suffering from a urinary tract infection. In these strains were applied the biotyping scheme described by Crichton and Old in 1993, which allowed the differentiation of this microorganism in different biotypes.
Results: The presence of 16 different biotypes of Escherichia coli strains studied was demonstrated. Biotypes 1 and 10 were the most identified with 20.59 and 17.62%, respectively.
Conclusions: According to the one described in the literature, the biotyping scheme used, shows its usefulness for discrimination in a wide range of biotypes of Escherichia coli recovered from urine samples obtained from patients with a clinical suspicion of infection urinary tract.
