  1. Pulmonary form: pneumonia that develops in immunocompromised individuals, with cough, fever, chest pain; disease can spread to other organs.

  3. Thrush: Amucous membrane infection in young, dibetic, or T-cell deficient patients. Lesions appear as whitish, valvety sores in the mouth and on the tongue. Underneath the whitish material, there is red tissue that may bleed easily.
    Yeast infection: Thick, white, odor-free discharge that appears like cottage cheese; itching; burning; swlling; pain and soreness.
    Uti: seen in hospitalized or nursing home patients; increased urinaary frequency; burning sensation upon urination; cloudy or discolored urine; blood in the urine.
    Fungemia: presence of fungi in blood.
    Organ seeding: fungemia disseminated and grow in the eye, liver, and spleen.
    • Scientific name: Candida albicans
    • Growth form: yeast
    • Type of mycosis: Opportunistic (cutaneous and                            systemic)
    • Disease:

    •             C) Urinary tract infection
    •             D) Fungemia
    •             E) Organ seeding
  4. Coccidioidomycosis: Pneumonia similar to Tb; fever, weight loss, chronic cough, and tender, red nodules under the skin (erythema nodosum).
    Disseminated disease: Skin lesions, granulomas in the liver and spleen, meningitis.
    • Scientific name: Coccidioides immitis
    • Growth form: Dimorphic mold
    • Type of mycosis: systemic
