|January 1, 1991
Summary
Coagulase-negative Staphylococci (CNS) are significant causes of pyoseptic infections in Moscow and Gorky. Species identification revealed diverse CNS strains, with S. epidermidis and S. haemolyticus being most prevalent.
Area of Science:
- Microbiology
- Clinical Infectious Diseases
Context:
- Pyoseptic infections pose a significant threat in hospital settings.
- Coagulase-negative Staphylococci (CNS) are increasingly recognized as important pathogens.
Purpose:
- To determine the etiologic significance of CNS in pyoseptic infections.
- To identify and classify CNS species prevalent in Moscow and Gorky.
- To develop a practical classification scheme for CNS.
Summary:
- Analysis of clinical isolates from cardiosurgical, cardiotherapeutic, and neonatal patients revealed the significant role of CNS in pyoseptic infections.
- Species identification, using the Kloos and Schleifer (1975) classification, showed a diverse range of CNS, with Staphylococcus epidermidis and Staphylococcus haemolyticus being the most common.
- Staphylococcus xylosus was frequently isolated from purulent foci, alongside Staphylococcus aureus.
- A specific CNS spectrum was observed, varying with hospital profile.
- A modified, brief CNS classification scheme was developed for practical laboratory use.
Impact:
- Highlights the importance of accurate CNS species identification for effective infection control.
- Provides a practical classification tool for clinical laboratories.
- Informs targeted therapeutic strategies against CNS infections.
