Insights

A fungal eye infection caused by Aspergillus pseudotamarii was successfully treated with topical natamycin. This specific fungus also produced harmful aflatoxins, highlighting a potential dual threat.

Area of Science:

  • Ophthalmology
  • Mycology
  • Infectious Diseases

Background:

  • Fungal keratitis is a serious ocular infection that can lead to vision loss.
  • Accurate identification of fungal pathogens is crucial for effective treatment.

Purpose of the Study:

  • To report a case of fungal keratitis caused by Aspergillus pseudotamarii.
  • To describe the successful treatment and etiological investigation of the infection.

Main Methods:

  • Clinical presentation and treatment of a patient with fungal keratitis.
  • Polyphasic approach including morphological and molecular techniques for fungal identification.
  • Analysis of aflatoxin production by the isolated fungus.

Main Results:

  • A male patient experienced redness, pain, and vision defects in the left eye.
  • Topical natamycin treatment resulted in complete healing of the corneal infiltrate within two weeks.
  • The causative agent was identified as Aspergillus pseudotamarii, a producer of aflatoxins.

Conclusions:

  • Aspergillus pseudotamarii can cause fungal keratitis.
  • Topical natamycin is an effective treatment for this condition.
  • The identification of aflatoxin production by this isolate warrants further investigation.

Fungal Phylum Ascomycota

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...

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...

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...

Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease...

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial...

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
