Insights

Prototheca wickerhamii rarely causes systemic infections in humans, often occurring in patients with comorbidities. This case highlights successful treatment of an immunosuppressed patient with lesions caused by this opportunistic alga.

Area of Science:

  • Medical Mycology
  • Infectious Diseases
  • Immunocompromised Hosts

Background:

  • Prototheca wickerhamii is a rare cause of human infection, typically seen in immunocompromised individuals.
  • Systemic infections by Prototheca wickerhamii are infrequent and often associated with underlying health conditions.
  • Opportunistic infections pose significant challenges in managing immunocompromised patients.

Purpose of the Study:

  • To illustrate the clinical manifestation of Prototheca wickerhamii infection in an immunosuppressed patient.
  • To document the treatment and outcome of a rare systemic algal infection.
  • To contribute to the understanding of Prototheca wickerhamii pathogenesis in vulnerable populations.

Main Methods:

  • Case report of a single immunosuppressed patient.
  • Clinical presentation and diagnostic findings were documented.
  • Treatment response to antifungal therapy was monitored.

Main Results:

  • The patient presented with lesions indicative of Prototheca wickerhamii infection.
  • Successful treatment was achieved using Liposomal amphotericin B.
  • Complete resolution of the lesions was observed post-treatment.

Conclusions:

  • Liposomal amphotericin B is an effective treatment for Prototheca wickerhamii infections.
  • Immunosuppression is a key risk factor for developing Prototheca wickerhamii infections.
  • Early diagnosis and appropriate antifungal therapy are crucial for favorable outcomes.

Diversity of Protists II

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Diversity of Protists I

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

Bacterial Phylum Spirochaetes

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...

Overview of Protists

Protists are diverse eukaryotic microorganisms that lack the specialized tissues of plants and animals and the chitinous cell walls of fungi. Their early divergence within Eukarya resulted in structural, functional, and ecological diversity. They are classified into supergroups such as Archaeplastida, Excavata, Amoebozoa, Rhizaria, Alveolata, and Stramenopiles, determined through genetic analysis and structural similarities.Structural and Functional AdaptationsProtists have various adaptations...

Bacterial Phylum Planctomycetes

Planctomycetes are a group of morphologically distinct bacteria predominantly classified into two orders: Planctomycetales and Brocadiales. These gram-negative bacteria exhibit unique features, including division by budding and the presence of stalks or appendages. Their cells are often found in rosette arrangements, and they are notable for possessing an S-layer in their cell envelope, which is relatively uncommon among bacteria. Additionally, Planctomycetes frequently exhibit intracellular...
