    Area of Science:

    • Medical Parasitology
    • Infectious Diseases
    • Travel Medicine

    Background:

    • Giardiasis, caused by Giardia lamblia, is a significant parasitic infection.
    • It is the leading cause of travelers' diarrhea worldwide.
    • Amoebiasis, caused by Entamoeba histolytica, is less common but also discussed.

    Purpose of the Study:

    • To provide a comprehensive overview of Giardia lamblia as a cause of travelers' diarrhea.
    • To detail the parasitology, distribution, and clinical aspects of giardiasis.
    • To outline diagnostic and therapeutic strategies for giardiasis and amoebiasis.

    Main Methods:

    • Literature review and synthesis of existing data on Giardia lamblia and Entamoeba histolytica.
    • Discussion of epidemiological, clinical, and therapeutic information.
    • Comparative analysis of giardiasis and amoebiasis in the context of travelers' diarrhea.

    Main Results:

    • Giardia lamblia is the most common parasitic cause of travelers' diarrhea.
    • Giardiasis has a widespread geographic distribution, prevalent in tropical/sub-tropical areas.
    • Effective treatments include quinacrine, metronidazole, and tinidazole.

    Conclusions:

    • Giardiasis requires understanding of its transmission, pathogenesis, and clinical presentation for effective management.
    • Accurate diagnosis and timely treatment are crucial for travelers.
    • While less frequent, amoebiasis-related diarrhea also warrants clinical attention.
