Title: Sporotrichosis: Causes, Symptoms, Daignosis, Prevention and Treatment

  • Sporotrichosis is a rare infection which is
    caused by a fungus known as sporothrix. This
    fungus lives throughout the world in soil and on
    plant matter like sphagnum moss, rose bushes, and
    hay. One can suffer from sporotrichosis by just
    coming in contact with the fungal spores in the
    environment.Cutaneous (skin) infection is the
    most common form of the infection. It happens
    when the fungus enters the skin through a small
    cut or scrape, usually after handling
    contaminated plant matter. Most cases of
    sporotrichosis have been linked with scratches or
    bites from animals, particularly cats.

Types of sporotrichosis
  • Cutaneous sporotrichosis is the most common form
    of the infection. It usually happens on a
    persons hand or the arm after they have been
    handling contaminated plant matter.
  • Pulmonary (lung) sporotrichosis is very rare
    condition but can happen after someone breathes
    in fungal spores from the environment.
  • Disseminated sporotrichosis happens when the
    infection spreads to another part of the body,
    like the bones, joints, or the central nervous
    system. This form of sporotrichosis generally
    affects people who have weakened immune systems,
    like people with HIV infection.

How is sporotrichosis diagnosed?
  • Sporotrichosis is typically diagnosed when your
    doctor takes a small tissue sample (biopsy) of
    the infected area of the body. The sample is sent
    to laboratory for tests to find out what is
    causing the infection. Blood tests can help
    diagnose severe sporotrichosis, but they often
    cant diagnose a cutaneous infection.

Symptoms of sporotrichosis
  • The symptoms of sporotrichosis rely on where the
    fungus is growing. Contact your doctor if you
    have symptoms that you think are related to
    sporotrichosis.Sporotrichosis usually affects
    the skin or tissues underneath the skin. Usually
    the first symptom of cutaneous sporotrichosis is
    small, painless bump that can be developed at any
    time from 1 to 12 weeks after exposure to the
    fungus.The bump can be red, pink, or purple,
    and it usually appears on the finger, hand, or
    arm where the fungus has entered through a break
    in the skin.

Symptoms of sporotrichosis
  • The bump will eventually grow larger and may
    look like an open sore or ulcer that is very slow
    to heal. Additional bumps or sores may appear
    later near the original one.Pulmonary (lung)
    sporotrichosis is less commonly occurred than the
    cutaneous form of the infection. Some of the
    symptoms of pulmonary sporotrichosis include
    cough, shortness of breath, chest pain, and
    fever.Symptoms of disseminated sporotrichosis
    basicdepend on the body part affected. For
    example, infection of the joints can cause joint
    pain that may be confused with rheumatoid
    arthritis. Infections of the central nervous
    system can involve difficulty thinking, headache,
    and seizures.

How is sporotrichosis treated?
  • Most cases of sporotrichosis only involve the
    skin or the tissues underneath the skin. It must
    be treated with prescription antifungal
    medication for several months and these
    infections are not life threatening. The most
    common treatment for this type of sporotrichosis
    is itraconazole, taken by mouth for 3 to 6
    months.Supersaturated potassium iodide (SSKI)
    is another treatment option that is available for
    cutaneous (skin) sporotrichosis. However, SSKI
    and azole drugs such as itraconazole should not
    be used at the time of pregnancy.

How is sporotrichosis treated?
  • Patients who are suffering with severe forms of
    sporotrichosis are usually treated with
    amphotericin B, which is given through a vein.
    Often itraconazole is used after the initial
    treatment with amphotericin B, for a total of at
    least 1 year of antifungal treatment. People
    suffering with sporotrichosis in the lungs may
    also need surgery to cut away the infected
