    Insights

    Intestinal protozoan infections, including Giardia intestinalis and Endolimax nana, affected 12.7% of patients. Nonpathogenic amoebas may contribute to intestinal disorders, though not directly linked to diarrhea in this study.

    Area of Science:

    • Medical Parasitology
    • Clinical Microbiology
    • Gastroenterology

    Background:

    • Intestinal parasitic protozoan infections are common globally.
    • Understanding the prevalence and clinical associations of these parasites is crucial for diagnosis and treatment.

    Purpose of the Study:

    • To determine the prevalence of intestinal protozoan infections in a hospital population.
    • To investigate the association between specific protozoan findings and various clinical diagnoses.

    Main Methods:

    • Analysis of stool samples from 10,418 patients at a Prague hospital.
    • Statistical evaluation of protozoan detection rates across different clinical diagnoses.

    Main Results:

    • 12.7% of patients had protozoan infections; Giardia intestinalis (3.5%), Entamoeba histolytica (0.3%), Endolimax nana (5.7%).
    • Endolimax nana showed increased frequency in eosinophilia, giardiasis, amoebiasis, and helminthiasis diagnoses.
    • Entamoeba coli was slightly more frequent in giardiasis and helminthiasis.
    • Entamoeba histolytica infections were often linked to travel abroad; no increased frequency was observed in patients with diarrhea.

    Conclusions:

    • Endolimax nana and Entamoeba coli may have a role in certain gastrointestinal conditions.
    • Nonpathogenic amoebas might be implicated in the pathogenesis of human intestinal disorders.
    • Further research is needed to elucidate the role of nonpathogenic protozoa in intestinal diseases.

    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...

    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 IV

    Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...
    Bacterial Gastroenteritis01:18

    Bacterial Gastroenteritis

    Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
    Giardiasis01:12

    Giardiasis

    Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
    Amebiasis01:28

    Amebiasis

    Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
