Virulence Characteristics of Escherichia coli in Nosocomial Urinary Tract Infection

Abstract excerpt

We examined 148 strains of Escherichia coli isolated from the urine from patients with nosocomial urinary tract infection (UTI). The prevalence of P fimbriation was only 11.5%. Of the strains, 17.6% expressed non-P M(R) adhesins (defined as strains expressing mannose-resistant but not P-specific hemagglutination); 33.1% produced hemolysin, and 15.2% expressed type 1C fimbriae. O6 was the most common group of O...
