[Typing of E. coli rough strains with phages (author's transl)]. 1981

W Nimmich, and E Straube, and G Naumann

Two phage-sets were used for the typing of 408 E. coli rough strains isolated from patients with urinary tract infections, Using the 13 phages A to M (11), we were able to type 225 (55.1 per cent) strains. 143 (35 per cent) of these strains were found to have K antigen, 84 different phage patterns could be recognized. Phage patterns GHK, M, F, and AM were the most common ones found. The application of the typical rough phages Br10, C21, 6SR, FP1, T4, and the Felix O (FO) phage led to the successful typing of 143 (35 per cent) strains, 80 of which (19.6 per cent) had a K antigen. About 70 per cent of the strains typable were found to belong to phage patterns which were represented by single phages, 24 different R phage patterns were observed. Considering both phage-sets the total typability amounted to 67 per cent. It is concluded that phage typing may be useful for the typing of E. coli rough strains in urinary tract infections in order to distinguish between relapse and reinfection.

D004926 Escherichia coli A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc. Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
