[Epidemiological studies of increasing appearances of Proteus inconstans (Providencia stuartii) infections (author's
Abstract:
Since proteus inconstans turns out to be the causative agent of an increasing amount of hospital infections, studies on this species are necessary. By means of bacteriocines, biochemical reactions and antibiograms 53 strains were subclassified. 47 strains displayed same biochemical properties, 44 strains showed the same antibiogram. By the method on the basis of bacteriocine typing 15 groups were established. The strains with the same biochemical properties and the same antibiograms could be further subclassified. The distribution of the different bacteriocine groups showed that the infections were not due to a single strain. In contrast there were some indices for cross-infections on some stations.
Insights
Studies on Proteus inconstans hospital infections are crucial. Bacteriocin typing revealed diverse strains, indicating cross-infections rather than a single source.
Area of Science:
- Microbiology
- Infectious Diseases
- Bacteriology
Context:
- Proteus inconstans is an emerging cause of hospital-acquired infections.
- Understanding the genetic diversity and transmission of this pathogen is vital for infection control.
Purpose:
- To subclassify 53 strains of Proteus inconstans using bacteriocin typing, biochemical reactions, and antibiograms.
- To investigate the origins and spread of Proteus inconstans in a hospital setting.
Summary:
- Biochemical analysis showed homogeneity in 47 strains, while antibiograms were similar in 44 strains.
- Bacteriocin typing differentiated the strains into 15 distinct groups.
- The diverse bacteriocin profiles suggest multiple strains are responsible for infections, with evidence of cross-transmission between hospital wards.
Impact:
- Highlights the complexity of Proteus inconstans hospital infections.
- Informs infection control strategies by identifying potential cross-infections.
- Emphasizes the need for advanced typing methods beyond biochemical and antibiogram analysis for accurate pathogen surveillance.
