Summary
Marine microorganisms from Morocco
Area of Science:
- Marine microbiology
- Medical mycology
- Natural product discovery
Background:
- Pathogenic yeasts like Candida and Cryptococcus pose significant health risks.
- Marine environments are rich sources of novel bioactive compounds.
- Antifungal resistance necessitates the discovery of new therapeutic agents.
Purpose of the Study:
- To screen marine microorganisms from the Moroccan Atlantic Ocean for antifungal activity.
- To identify potential sources of novel antifungal compounds against pathogenic yeasts.
- To investigate the antifungal potential of marine-derived microbes.
Main Methods:
- Isolation and screening of 34 marine microorganisms from various marine sources (seawater, seaweed, sediment, invertebrates).
- Agar diffusion method used to assess antifungal activity against four pathogenic yeast species.
- Identification of promising antifungal-producing microorganisms using standard microbiological techniques.
Main Results:
- 38% (13 out of 34) of isolates exhibited antifungal activity against at least one yeast species.
- Significant activity observed against Candida albicans (11-12 isolates) and Cryptococcus neoformans (13 isolates).
- Six isolates showed activity against nystatin and amphotericin B-resistant Candida tropicalis; nine isolates displayed strong fungicidal activity.
Conclusions:
- Marine microorganisms from the Moroccan Atlantic Ocean are a promising source of antifungal agents.
- Several isolates demonstrated potent activity against medically important yeasts, including drug-resistant strains.
- Further research into these marine microbes could lead to the development of new anti-Candida and anti-Cryptococcus fungicides.

106
Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to...

56
Marine microbial ecosystems are shaped by distinct physicochemical limits, including high salinity, low nutrient availability, and fluctuating oxygen levels. These conditions favor smaller microbial cell sizes, which maximize their surface-to-volume ratio for efficient nutrient uptake.Microbial activity and community composition are closely linked to biogeochemical cycles, particularly in dynamic environments like estuaries, where halotolerant microbes thrive in response to variable salinity...

771
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...

3.7K
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...

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...
