[Sensitivity to polyvalent therapeutic staphylococcal bacteriophage as a supplementary criterion of staphylococcal
Abstract:
It is recommended to use the capacity of pathogenic staphylococci to be lysed by polyvalent therapeutic staphylococcal bacteriophage in the capacity of an additional simple and accessible criterion of staphylococcus pathogenicity. Of 147 strains of the pathogenic plasmacoagulating staphylococci 101 were lysed by the phage and of 166 nonplasmocoagulating nonpathogenic strains--only 6. This test correlated with the other signs of staphylococcus (lecithinase and hemolytic activity). The simplicity and sufficient specificity of this test permits to use it in any practical laboratory. Polyvalent diagnostic phage can be used on the basis of therapeutic bacteriophage by its additional adaptation to the pathogenic strains of staphylococcus.
Insights
A new method uses bacteriophage lysis to identify pathogenic staphylococci. This simple test accurately distinguishes harmful bacteria, aiding in clinical diagnostics.
Area of Science:
- Microbiology
- Bacteriology
Context:
- Staphylococcus pathogenicity is crucial for infection control.
- Accurate identification of pathogenic strains is essential in clinical settings.
- Existing methods for assessing staphylococcal pathogenicity can be complex.
Purpose:
- To evaluate the efficacy of polyvalent therapeutic staphylococcal bacteriophage lysis as a diagnostic criterion for staphylococcus pathogenicity.
- To correlate bacteriophage lysis with other established pathogenicity markers like lecithinase and hemolytic activity.
Summary:
- Polyvalent therapeutic staphylococcal bacteriophage demonstrated significant lysis in pathogenic Staphylococcus strains (101/147) compared to nonpathogenic strains (6/166).
- This bacteriophage lysis test showed strong correlation with lecithinase and hemolytic activity, indicating its reliability.
- The test is simple, accessible, and specific, making it suitable for practical laboratory use.
Impact:
- This method offers a simple and accessible additional criterion for assessing staphylococcus pathogenicity.
- The findings support the adaptation of polyvalent diagnostic phages for routine laboratory use.
- Improved diagnostics can lead to better management and treatment of staphylococcal infections.
