Insights

Micro- and nanoparticles called Maresometrade mark, derived from microalgae, effectively prevent dermal colonization by methicillin-resistant Staphylococcus aureus (MRSA) strains. This offers a potential new strategy for anti-infectious skin care.

Area of Science:

  • Microbiology
  • Dermatology
  • Biotechnology

Background:

  • Methicillin-resistant Staphylococcus aureus (MRSA) poses a significant challenge in healthcare settings.
  • Dermal colonization by MRSA can lead to various infections.
  • Novel strategies are needed to prevent MRSA skin colonization.

Purpose of the Study:

  • To investigate the efficacy of micro- and nanoparticles (Maresometrade mark) in preventing dermal colonization by MRSA.
  • To evaluate Maresometrade mark derived from microalgae for anti-MRSA properties.

Main Methods:

  • Maresometrade mark were prepared from selected microalgae using a novel emulsion technique.
  • The inhibitory effect of Maresometrade mark on MRSA strains was tested on 'mouse ear' and 'cow udder teat' models.
  • Quantification of MRSA reduction after skin pretreatment with Maresometrade mark.

Main Results:

  • Maresometrade mark, specifically Bio33-Maresometrade mark from Nostocales cyanobacteria, inhibited dermal colonization by multiple MRSA strains, including vancomycin-resistant strains.
  • Pretreatment with Maresometrade mark reduced attached MRSA by 3-4 log units compared to controls.
  • The nanoparticles effectively encapsulated microalgal lipids and components.

Conclusions:

  • Maresometrade mark demonstrate significant potential in preventing MRSA dermal colonization.
  • Prophylactic skin care with Maresometrade mark could be a valuable addition to anti-infectious strategies against MRSA.
  • Microalgae-derived nanoparticles offer a promising avenue for antimicrobial applications.

Microbial Corrosion

Microbiologically Influenced Corrosion (MIC) is a significant form of material degradation caused by the metabolic activities of microorganisms. This phenomenon poses substantial challenges across various industries, including oil and gas, maritime, and water treatment sectors.MIC occurs when microorganisms, such as bacteria, archaea, and fungi, colonize metal surfaces, forming biofilms that alter the local electrochemical environment. These biofilms can lead to the production of corrosive...
Clinical Significance of Antibiotic Resistance01:25

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...
The Skin Microbiota01:27

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...
Surface Membrane Barriers01:18

Surface Membrane Barriers

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Gene Regulation in Microbial Communities: Quorum Sensing

Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...
