K-Antigen, Adhärenzfaktor, Dulcitol-Abbau und Hämolysin-Bildung bei E. coli-R-Stämmen aus Urin

Correlation between blood group phenotype and virulence properties of Escherichia coli in patients with chronic urinary tract infection

“…Confluent or semiconfluent lysis by K1 phages was regarded as documenting the presence of K1 antigen [14].…”

Detection of rough Escherichia coli K1 strains using K1 specific phages

“…One of the most common and important antigens ofE. coli rough strains [1][2][3][4][5][6][7][8][9][10][11][12]. This obviously seems to be true ofE.…”

“…Recently we were able to demonstrate that E. coli rough strains isolated from patients with urinary tract infections were often associated with virulence factors like capsules and fimbriae [12]. In this study the presence of K1 antigen in capsulated rough strains was tested using Kl-specific phages recently described by Gross et al [13] in comparison with agglutination and immunodiffusion techniques.…”

“…The presence of capsules was concluded from the inagglutinability of live cultures in saline solutions [12]. The presence of capsules was concluded from the inagglutinability of live cultures in saline solutions [12].…”
