Summary
Staphylococcus aureus (S. aureus) colonization rates did not differ between acne patients and healthy individuals. However, S. aureus antibiotic resistance patterns varied, suggesting a complex role in acne vulgaris pathogenesis.
Area of Science:
- Dermatology
- Microbiology
- Infectious Diseases
Background:
- Acne vulgaris pathogenesis may involve Staphylococcus aureus (S. aureus).
- Understanding S. aureus colonization and antibiotic resistance is crucial for acne treatment strategies.
Purpose of the Study:
- To investigate S. aureus colonization prevalence in acne patients versus healthy controls.
- To analyze antibiotic susceptibility patterns of S. aureus isolates from both groups.
Main Methods:
- A case-control study involving 324 participants (166 acne patients, 158 healthy controls).
- Nasal swabs were cultured for S. aureus identification.
- Antibiotic sensitivity testing was performed using standard laboratory methods.
Main Results:
- S. aureus colonization rates were similar between acne patients (21.7%) and controls (26.6%).
- Acne patients showed higher resistance to doxycycline and tetracycline.
- Control samples exhibited greater resistance to cotrimoxazole compared to patient samples.
Conclusions:
- The role of S. aureus in acne pathogenesis remains controversial.
- Microbiological data suggest a complex, rather than direct, contribution of S. aureus to acne.

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...
01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
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...
01:25Clinical 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...
01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.

01:25Mechanism of Antibiotic Resistance in MRSA
Antibiotic resistance in bacteria arises when microorganisms evolve the ability to withstand drugs designed to kill them or inhibit their growth, rendering once-effective treatments useless. This phenomenon, driven by genetic change and selection under antibiotic exposure, poses a profound threat to modern medicine. Mechanisms include drug-inactivating enzymes (e.g., β-lactamases), efflux pumps that eject antibiotics, mutations altering antibiotic targets, decreased drug uptake, and acquisition...
