    Insights

    This study reveals the immune-driven pathological changes in the mouse caecum during experimental escherichiosis. Findings highlight the caecum

    Area of Science:

    • Gastroenterology
    • Immunology
    • Microbiology

    Background:

    • Escherichiosis, an infection caused by Escherichia coli, can significantly impact the gastrointestinal tract.
    • Understanding the host's response is crucial for developing effective treatments.

    Purpose of the Study:

    • To characterize the morphofunctional changes in the mouse caecum during experimental escherichiosis.
    • To elucidate the dynamics of the infectious process and the caecum's role.

    Main Methods:

    • Experimental escherichiosis model in mice.
    • Morphological, immunomorphological, morphometrical, and electron microscopy techniques.
    • Analysis of caecal tissue from 15 minutes to 2 weeks post-inoculation.

    Main Results:

    • Observed dynamic changes in microcirculation within the caecum.
    • Noted increased lymphoplasmocellular infiltration and dystrophic alterations in neuroplex cells.
    • Documented degranulation of mast and endocrine cells, indicating an immune-mediated pathological process.

    Conclusions:

    • The pathological process in the caecum during experimental escherichiosis is primarily immune-driven.
    • The caecum functions as an integral part of the endocrine system in response to infection.

    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...

    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...
