|January 1, 1994
Summary
Researchers identified key biologic traits to distinguish between resident and transient staphylococcal bacteria in carriers. Resident strains notably inactivate anti-infectious resistance factors, aiding in bacterial identification.
Area of Science:
- Microbiology
- Bacterial Pathogenesis
- Infectious Disease Epidemiology
Background:
- Staphylococcal species represent a significant component of human microflora.
- Differentiating between resident and transient staphylococcal strains is crucial for understanding infection dynamics and carrier states.
- Current methods for differentiating these strains may lack specificity or efficiency.
Purpose of the Study:
- To identify and characterize informative biologic features that distinguish resident from transitory staphylococcal microflora in bacterial carriers.
- To develop a diagnostic tool for classifying staphylococcal strains based on these identified characteristics.
Main Methods:
- Analysis of biologic characteristics of staphylococcal isolates from bacterial carriers.
- Application of probability statistics and diagnostic coefficient calculations.
- Development of a diagnostic coefficient table for strain differentiation.
Main Results:
- Identification of specific biologic characteristics differentiating resident and transient staphylococcal strains.
- Demonstration that resident staphylococcal strains possess a greater capacity to inactivate anti-infectious resistance factors.
- Development of a diagnostic coefficient table enabling identification of 76.6-82.5% of examined cultures.
Conclusions:
- Specific biologic characteristics can reliably differentiate between resident and transient staphylococcal microflora.
- The inactivation of anti-infectious resistance factors is a key differentiator, more pronounced in resident strains.
- The developed diagnostic coefficient table offers a statistically-based method for improved staphylococcal strain classification.

01:26Differential Staining Technique
Differential staining is an essential microbiological technique that exploits variations in cell wall structures to classify and identify microorganisms. It facilitates the distinction of bacteria, aiding in diagnostic and research applications. Two of the most widely used differential staining methods are Gram staining and acid-fast staining, both of which rely on the chemical and structural differences in bacterial cell walls.Gram Staining TechniqueGram staining differentiates bacteria by...
01:30Development of Human Microbiota
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
01:27The Skin Microbiota
The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...
01:29Microbiota of the Respiratory Tract
The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...
01:25Colonisation of Pathogens
Pathogen colonization of host tissues is a critical step in the development of infectious diseases. Various pathogenic microorganisms, including bacteria, fungi, viruses, and protozoa, have evolved complex strategies to attach to, invade, and persist within host environments. These mechanisms enable pathogens to establish infections, evade immune responses, and resist antimicrobial treatments.Attachment to Host CellsIn bacteria, colonization typically begins with adherence to host epithelial...
01:29Staphylococcal Skin Infections
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
