Melanin depletion affects Aspergillus flavus conidial surface proteins, architecture, and virulence.

Melanin is an Aspergillus flavus cell wall component that provides chemical and physical protection to the organism. However, the molecular and biological mechanisms modulating melanin-mediated host-pathogen interaction in A. flavus keratitis are not well understood.

Challenges in Post-cataract Surgery Nocardia Endophthalmitis: Management Strategies and Clinical Outcomes.

Purpose: To describe the clinical and microbiological features, management strategies, outcomes, and challenges in post-cataract surgery nocardia endophthalmitis.

Methods: We evaluated 28 eyes with culture-confirmed Nocardia endophthalmitis following cataract surgery. Data were collected regarding age, gender, clinical presentation, management modalities used, and final outcomes.

Molecular identification of species causing endophthalmitis using multilocus sequence analysis (MLSA): a 10-year perspective.

spp. can cause several ocular infections, such as keratitis, endophthalmitis and scleral abscesses. Molecular identification of spp.

Clinical presentations, genotypic diversity and phylogenetic analysis of species causing keratitis.

keratitis is a sight-threatening corneal infection that is commonly reported among contact lens users and those suffering from corneal trauma. The prevalence of species or genotypes in causing keratitis infection is not well known. This study was conducted to identify and genotype isolates from keratitis patients, targeting the ribosomal nuclear subunit () region, and describe the associated clinical presentation and treatment outcome.
