[New findings on alpha-hemolytic strains of E. coli in urinary tract infections. II. Antigen structure, resistance, production of colicins and siderophores].

Abstract

Alphahaemolytic uropathogenic strains of E. coli (UPEC) belong mostly into the serogroup 04, 06, 018 and 075. UPEC are resistant against antibacterial substances and against the bactericide action of serum. Properties which condition the virulence of these strains are also colicin and siderophore production.
