Insights

Acanthamoeba and Fusarium species interactions can worsen infectious keratitis. This study shows their co-culture enhances survival and virulence, impacting contact lens-related eye infections.

Area of Science:

  • Microbiology
  • Ophthalmology
  • Infectious Diseases

Background:

  • Contact lens-related infectious keratitis is increasingly linked to Acanthamoeba and Fusarium species.
  • Co-infections with these organisms are reported, suggesting potential synergistic interactions.

Purpose of the Study:

  • To investigate the interaction between Acanthamoeba castellanii and Fusarium solani.
  • To understand the implications of this interaction on keratitis pathogenesis.

Main Methods:

  • Co-culture experiments involving three strains of Acanthamoeba castellanii and Fusarium conidia.
  • Evaluation of fungal growth, amoebal survival, and encystment rates.

Main Results:

  • Fusarium conidia were internalized and germinated within Acanthamoeba.
  • Co-culture with Acanthamoeba significantly increased Fusarium growth.
  • Fusarium enhanced Acanthamoeba survival, with strain-specific effects.
  • Fungal presence increased Acanthamoeba encystment in one strain.

Conclusions:

  • Acanthamoeba castellanii and Fusarium solani interactions influence the survival of both microorganisms.
  • These interactions may enhance the virulence of these pathogens.
  • The interaction between these species could significantly impact the severity of infectious keratitis.

Fungal Phylum Microsporidia01:28

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...

Antifungal Agents01:15

Antifungal Agents

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...

Diversity of Protists II

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Microbe-Plant Interactions01:09

Microbe-Plant Interactions

Microbe-plant interactions represent a dynamic spectrum of associations shaped by intricate chemical signaling. These interactions can be neutral, beneficial, or detrimental, and profoundly influence plant physiology, growth, and ecosystem function. The plant microbiome, comprising bacteria, fungi, archaea, protists, and viruses, plays a pivotal role in mediating these effects through surface colonization, internal colonization, or systemic symbiosis.Mutualistic associations, particularly with...

Microbial Interactions: Cooperation

Microbial cooperation involves beneficial interactions in which different species work together for individual or mutual advantage. These interactions can profoundly influence ecological dynamics and evolutionary processes, and they are essential to many pathogenic and symbiotic relationships.Nematode–Bacteria CooperationA striking example is the relationship between the Gram-negative bacterium Xenorhabdus nematophila and the parasitic nematode Steinernema carpocapsae. Juvenile nematodes...

Microbiome of the Eye01:22

Microbiome of the Eye

The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
