title: Comparative prevalence of virulence factors in Escherichia coli causing urinary tract infection in male infants with and without bacteremia.
abstract: Escherichia coli isolates causing urinary tract infection in 83 male infants younger than 90 days with and without bacteremia were compared for phylogenetic groups and the presence of 10 virulence factors. Our result suggest that the absence of both hemolysin and antigen K1 may be used as a negative predictive factor for bacteremia.
