Insights

Prototheca infections, though rare, can cause skin and soft tissue issues. This study reviews seven cases of Prototheca infections, highlighting clinical presentations and outcomes.

Area of Science:

  • Medical Mycology
  • Infectious Diseases
  • Microbiology

Background:

  • Prototheca species are ubiquitous microalgae capable of causing human infections (protothecosis).
  • Protothecosis commonly manifests as localized cutaneous or subcutaneous lesions, such as olecranon bursitis.
  • Disseminated protothecosis is a rare but serious complication, particularly in immunocompromised individuals.

Purpose of the Study:

  • To describe the clinical characteristics and management of Prototheca infections.
  • To review the experience of a single institution with seven patients diagnosed with Prototheca infections.
  • To contribute to the understanding of Prototheca infection presentations in humans.

Main Methods:

  • Retrospective case series analysis.
  • Review of medical records for seven patients with confirmed Prototheca infections.
  • Analysis of clinical data, treatment, and outcomes.

Main Results:

  • Seven cases of Prototheca infections were identified.
  • Common presentations included localized soft tissue infections and bursitis.
  • Details on specific patient demographics, treatment regimens, and clinical outcomes were documented.

Conclusions:

  • Prototheca infections represent a spectrum of disease, from localized to disseminated forms.
  • Early recognition and appropriate management are crucial for favorable outcomes in protothecosis.
  • Further research is needed to fully elucidate optimal treatment strategies for Prototheca infections.

Fungal Phylum Microsporidia

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...

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...

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...

Infection01:20

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
