  1. Nosocomial infections caused by selected gram-negative bacteria at the anaesthesiology and intensive care unit of the teaching hospital in Brno.

    Article - En anglais

    In the course of 13 months we monitored the occurrence of strains of P. mirabilis, P. vulgaris, Kl. pneumoniae, including its indole-positive variant and S. marcescens in patients of the Anaesthesiology and Intensive Care Unit (AICU) of the Teaching Hospfital (TH) in Brno.

    Out of 436 patients hospitalized at that time, 95 (21.8%) were colonized or infected by one or all of the bacterial species studied.

    Out of those 95 patients, 48 (50.5%) came to the AICU already colonized or infected by one of the studied agents mostly from other wards of the TH or from other hospitals.

    At the AICU, 32 of them were reinfected or superinfected by one, two or all of the bacterial species studied.

    Of the 436 hospitalized patients, 79 (18.1%) were newly infected, reinfected or superinfected.

    By serotyping, proticine production and proticine sensitivity (P-S) typing and phage typing we demonstrated the endemization of some P-S types and phage types of the bacterial species studied and their spreading among the contemporaneously hospitalized patients.

    The endemic strains of P. mirabilis included P-S types P5/S6, S7, S9 and P5/S6, S7 ; P0 :

    • The endemic strains of P. mirabilis included P-S types P5/S6, S7, S9 and P5/S6, S7 ;

    • S9 ;

    • P1/S2,

    • S11 and P1/S11.

    The two biotypes of Klebsiella, i.e. pneumoniae and K. oxytoca, were identically sensitive to some of the phages 1,2,3,8 and 106, particularly to phages 2 and 3, or 2,3 and 106.

    The isolated strains of Serratia were absolutely resistant to the 26 bacteriophages used.
