Epidemiological markers for pseudomonas aeruginosa 7. nosocomial occurrence in a urological ward comparison of 2 phage typing sets pyocin typing and serogrouping


, : Epidemiological markers for pseudomonas aeruginosa 7. nosocomial occurrence in a urological ward comparison of 2 phage typing sets pyocin typing and serogrouping. Archivum Immunologiae et Therapiae Experimentalis 27(3): 447-458

A comparison of 2 pyocin typing methods with serogrouping and 2 phage typing sets was made. A contaminated bladder irrigation fluid of 0.05% silver nitrate solution caused a series of urinary tract infections. By all systems, fewer of the present strains were typable than usual. Among the phage typing sets the one developed by Lindberg et al. typed only 66%, whereas that selected by Bergan typed 83%, both less than observed previously. The set of Lindberg et al. also rendered longer pattern codes and yielded more variable results with related strains. A set of pyocin indicator strains, selected from the strains to be typed, was more suitable than one developed elsewhere. Comparison of 5 different methods of epidemiological typing of P. aeruginosa indicated that phage typing alone is not entirely satisfactory for this species and should always be combined with serogrouping.
