Summary
Two rare cases of filamentous fungal keratitis caused by Pseudallescheria boydii and Colletotrichum coccodes were reported. In vivo confocal microscopy (IVCM) effectively monitored treatment response in these uncommon ocular infections.
Area of Science:
- Ophthalmology
- Mycology
- Infectious Diseases
Background:
- Filamentous fungal keratitis is a serious ocular infection, often associated with trauma.
- Prompt diagnosis and appropriate medical therapy are crucial for managing fungal keratitis.
Observation:
- Two cases of filamentous fungal keratitis in farmers are presented, following ocular trauma from plants.
- The causative agents were identified as Pseudallescheria boydii (P. boydii) and Colletotrichum coccodes.
Findings:
- Slit-lamp biomicroscopy showed decreased corneal infiltration.
- In vivo confocal microscopy (IVCM) demonstrated reduced fungal hyphae density, confirming treatment efficacy.
- No unique confocal features distinguished these rare fungal keratitis cases from others.
Implications:
- Awareness of rare fungal pathogens like P. boydii and C. coccodes is important for effective treatment.
- In vivo confocal microscopy (IVCM) is a valuable tool for monitoring therapeutic response in fungal keratitis.
- Understanding antibiotic susceptibility patterns is key for managing these uncommon infections.

Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...

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...

Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...

Basidiomycota is a diverse phylum of fungi that includes ecologically significant decomposers such as white rot fungi, symbionts like mycorrhizal fungi, plant pathogens such as rusts and smuts, and edible species like Agaricus bisporus (the common button mushroom). These fungi play crucial roles in nutrient cycling, symbiotic relationships, and even human health. Their defining feature is the basidium, a microscopic club-shaped structure responsible for producing basidiospores.Fruiting Bodies...
