    Study Notes

    Tinea (Ringworm)

    • Caused by dermatophytes, which infect superficial keratinized structures.
    • Transmitted through direct contact, leading to chronic skin infections characterized by itchiness (pruritus).
    • Symptoms worsen in hot and humid environments.

    Tinea Versicolor

    • Results from Malassezia furfur, a type of yeast, causing superficial skin infection.
    • Characterized by hypopigmented areas on the skin.
    • Typically asymptomatic but common in hot and humid weather.

    Candida albicans

    • Part of normal skin flora, upper respiratory tract, and female genital tract.
    • Can become opportunistic when host defenses are impaired.
    • Leads to oral thrush, presenting as white patches in the mouth.
    • Can cause vulvovaginitis, featuring itching and cottage cheese-like vaginal discharge.
    • Associated with chronic infections including Trichomonas vaginalis.

    Trichomonas vaginalis

    • Spindle-shaped protozoan with four anterior flagella.
    • Transmitted through sexual contact, causing vaginal and prostate infections.
    • Symptoms include watery, foul-smelling greenish vaginal discharge, itching, and burning sensation around the vagina.
    • Men often remain asymptomatic.

    Entamoeba histolytica

    • Anaerobic protozoan prevalent in crowded conditions and poor sanitation.
    • Spread via food and water contamination, resulting in acute amoebic dysentery.
    • Invades the colon, causing loose stools mixed with blood and mucus.
    • Painful defecation is common.

    Hookworm

    • Adult worms reside in the intestinal lumen, feeding on blood from intestinal capillaries.
    • Nutritional deficiencies occur due to blood loss in the small intestine, leading to iron deficiency anemia.
    • Transmission occurs via the fecal-oral route with larval penetration through skin.

    Lifecycle of Hookworm

    • Adult worms live in the colon and release eggs in feces.
    • Eggs in the soil hatch into larvae.
    • Larvae can penetrate the intestine wall, migrate to the lungs, and ascend to the trachea to be swallowed, reaching the intestine again to mature into adult worms.
    • Damage to the intestine occurs due to adult worms, while larval migration results in lung inflammation.
    • Severe infections can lead to malnutrition, particularly in children.
