Clinical Significance of Antibiotic Resistance

Clinical 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...

Staphylococcal Skin Infections

Staphylococcal 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...

The Skin Microbiota

The 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...

Fungal Phylum Microsporidia

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Skin Diseases and Disorders

Skin 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.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Microbial Interactions: Parasitism

Microbial Interactions: Parasitism

Parasitism is a form of microbial interaction in which parasitic microbes exploit a host organism for nutrients and shelter, often at the host's expense. Unlike mutualistic relationships, where both organisms benefit, parasitism benefits only the parasite and harms the host.Classification of ParasitesMicrobial parasites are broadly classified based on their location relative to the host.Ectoparasites remain on the host’s surface, such as the skin or outer tissues, drawing nutrients...

Area of Science:

Parasitology
Dermatology
Infectious Diseases

Background:

Scabies, caused by the Sarcoptes scabiei mite, was historically under-researched due to limited mite availability.
The disease causes significant morbidity, particularly in disadvantaged communities and immunocompromised individuals.
Scabies infestations exacerbate bacterial infections, leading to severe conditions like rheumatic heart disease.

Purpose of the Study:

To review the current understanding of scabies and its associated diseases.
To present novel research tools, including a scabies mite database and a porcine model.
To identify potential therapeutic targets for scabies treatment.

Main Methods:

Analysis of a public database of ~45,000 scabies mite expressed sequence tags.
Utilizing a newly developed porcine in vivo model for scabies research.
Investigating novel mite proteins involved in survival, digestion, and host defense evasion.

Main Results:

Identification of crucial scabies mite proteins involved in digestion and immune evasion.
Discovery of potential therapeutic targets, including inactivated cysteine proteases.
Validation of a porcine model for testing potential scabies inhibitors.

Conclusions:

Scabies is a significant public health concern, linked to serious secondary bacterial infections and rheumatic heart disease.
Fundamental research tools have been developed, enabling advanced study of scabies.
Novel therapeutic strategies targeting mite-specific molecules are now feasible, potentially reducing scabies prevalence and its sequelae.
