Coagulase-negative strains of Staphylococcus pyogenes
Journal of Clinical Pathology
|January 1, 1972
Summary
Two coagulase-negative Staphylococcus pyogenes strains were isolated and characterized. The deoxyribonuclease test is recommended to reliably confirm Staphylococcus pyogenes identification beyond coagulase testing alone.
Area of Science:
- Microbiology
- Bacteriology
Background:
- Accurate identification of Staphylococcus pyogenes is crucial for clinical and epidemiological purposes.
- Coagulase testing is a standard method for differentiating Staphylococcus species.
Purpose of the Study:
- To report the isolation and biochemical characterization of coagulase-negative Staphylococcus pyogenes strains.
- To evaluate the reliability of coagulase tests for Staphylococcus pyogenes identification.
- To recommend confirmatory tests for accurate Staphylococcus pyogenes identification.
Main Methods:
- Isolation and cultivation of bacterial strains.
- Biochemical characterization including coagulase and deoxyribonuclease (DNase) tests.
Main Results:
- Two strains of coagulase-negative Staphylococcus pyogenes were successfully isolated.
- Biochemical profiles of the isolates were documented.
- The deoxyribonuclease test demonstrated utility as a confirmatory method.
Conclusions:
- Coagulase-negative Staphylococcus pyogenes can be isolated and identified.
- Relying solely on coagulase tests may lead to misidentification of Staphylococcus pyogenes.
- The deoxyribonuclease test is a valuable adjunct for confirming Staphylococcus pyogenes identification.

01:30Bacterial Phylum Spirochaetes
Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased by a...
01:30Bacterial Phylum Actinobacteria
Coryneform bacteria are gram-positive, aerobic, nonmotile rods that exhibit irregular, club-shaped, or V-shaped arrangements. Their V-shape results from snapping division, where the inner cell wall layer forms the cross-wall, while the outer layer remains intact until it ruptures on one side, causing the daughter cells to bend away.The primary genera are Corynebacterium and Arthrobacter. Corynebacterium includes diverse species, ranging from saprophytes to pathogens like Corynebacterium...
01:20Determinants of Bacterial Pathogenicity and Virulence
Pathogenic bacteria employ a variety of strategies to establish infections, including the secretion of extracellular enzymes that act as potent virulence factors. These enzymes facilitate bacterial colonization of host tissues and help evade immune surveillance. By targeting structural components of host tissues and interfering with immune mechanisms, these enzymes play a pivotal role in disease progression.Extracellular Enzymes Facilitating Tissue Invasion: Several bacterial pathogens secrete...
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...
01:27Streptococcal Pharyngitis
Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
01:25Clinical Significance of Antibiotic Resistance
Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
