    Area of Science:

    • Parasitology
    • Infectious Diseases
    • Veterinary Medicine

    Background:

    • The host-parasite relationship in Trypanosoma cruzi infection, the causative agent of Chagas' disease, presents complex challenges in experimental modeling.
    • Existing studies utilize diverse animal models (dogs, monkeys, rabbits), leading to difficulties in comparing results and interpretations.
    • A significant gap exists in consistent experimental studies that fully capture the spectrum of human infection and disease manifestations.

    Purpose of the Study:

    • To review and evaluate various experimental models used for studying Trypanosoma cruzi infection.
    • To highlight the need for a standardized and suitable experimental model that mimics human Chagas' disease.
    • To emphasize the importance of modeling the functional and organic disorders associated with the disease, particularly autonomic nervous system alterations.

    Main Methods:

    • Review of existing literature on experimental models for Trypanosoma cruzi infection.
    • Analysis of host-parasite interactions in different animal species.
    • Discussion of methodological approaches and their limitations in current research.

    Main Results:

    • A wide variety of animal species have been employed, but a lack of consistency hinders comparative analysis.
    • Methodological diversity across studies complicates the interpretation of results and the understanding of the disease's progression.
    • Current models often fail to fully replicate the multifaceted stages and pathological outcomes observed in human Chagas' disease.

    Conclusions:

    • There is a critical need for a well-defined and consistent experimental model for Trypanosoma cruzi.
    • Such a model should encompass all stages of infection and accurately reflect the functional and organic disorders seen in humans, including autonomic nervous system dysfunction.
    • Advancing Chagas' disease research and therapeutic development requires improved experimental models that allow for reliable and comparable data generation.
