Abstract

Insights

This case report details a rare polymicrobial fungal keratitis in a child caused by Candida lusitaniae, Candida parapsilosis, and Geotrichum candidum. Combined topical and systemic fluconazole effectively treated this infection, highlighting key risk factors.

Area of Science:

  • Ophthalmology
  • Mycology
  • Infectious Diseases

Background:

  • Fungal keratitis is a serious ocular infection, often associated with trauma and corticosteroid use.
  • Polymicrobial fungal keratitis presents unique diagnostic and therapeutic challenges.

Observation:

  • A three-year-old child presented with fungal keratitis following vegetable matter eye trauma and prolonged corticosteroid eyedrop use.
  • Corneal scraping cultures identified a polymicrobial infection involving Candida lusitaniae, Candida parapsilosis, and Geotrichum candidum.

Findings:

  • The patient was treated with topical 0.2% and systemic fluconazole.
  • Complete resolution of the corneal lesion was achieved with no recurrence.
  • This is the first reported case of fungal keratitis caused by the combination of C. lusitaniae and G. candidum.

Implications:

  • Corneal trauma with vegetative matter and indiscriminate corticosteroid use are significant risk factors for developing fungal keratitis.
  • Combination therapy with topical and systemic fluconazole is effective for treating this specific polymicrobial fungal keratitis.
  • This case expands the understanding of causative agents and effective treatments for polymicrobial fungal keratitis.

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...

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...

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
