Insights

A case of Aspergillus tamarii keratitis, a fungal eye infection, was successfully treated. Ocular injury was a key factor, and combination antifungal therapy proved effective against this rare pathogen.

Area of Science:

  • Ophthalmology
  • Medical Mycology
  • Infectious Diseases

Background:

  • Fungal keratitis is a significant cause of visual impairment globally.
  • Aspergillus species are common causes of fungal keratitis, particularly in tropical and subtropical regions.
  • Ocular trauma is a well-established risk factor for microbial keratitis.

Observation:

  • A patient presented with keratitis following an ocular injury.
  • The causative agent was identified as Aspergillus tamarii through morphological and molecular analyses.
  • This represents the first reported case of keratomycosis caused by Aspergillus tamarii.

Findings:

  • Topical natamycin and econazole, followed by oral ketoconazole, were effective in treating the Aspergillus tamarii keratitis.
  • Morphological characteristics and sequence analysis confirmed the isolate as Aspergillus tamarii.
  • Aspergillus tamarii, belonging to Aspergillus section Flavi, has not been previously implicated in human keratomycosis.

Implications:

  • This case expands the spectrum of Aspergillus species known to cause keratomycosis.
  • Highlights the importance of considering less common Aspergillus species in the diagnosis of fungal keratitis.
  • Emphasizes the efficacy of combination antifungal therapy in managing challenging fungal eye infections.

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
Glaucoma: Overview01:25

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
Candidiasis01:20

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
Toxoplasmosis01:28

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...

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...
