Overview

Sporotrichosis is a long-term (chronic) skin infection that is caused by a fungus called ‘’Sporothrix schenckii‘’

What are the symptoms of Sporotrichosis?

The time between the tick bite and when symptoms occur is about 7 - 9 days. This is called the incubation period.

Symptoms may seem like the flu (influenza), and may include:

Other possible symptoms:

A rash appears in fewer than half of cases. Sometimes, the disease may be mistaken for Rocky Mountain spotted fever. The symptoms are often quite general, but patients are sometimes sick enough to see a doctor.

What causes Sporotrichosis?

Sporotrichosis is caused by bacteria that belong to the family called Rickettsiae. Rickettsial bacteria cause a number of serious diseases worldwide, including Rocky Mountain spotted fever and typhus. All of these diseases are spread to humans by a tick, flea, or mite bite.

Scientists first described Sporotrichosis in 1990, and have identified two types in the United States:

  • Human monocytic Sporotrichosis (HME) is caused by the rickettsial bacteria called Ehrlichia chaffeensis.
  • Human granulocytic Sporotrichosis (HGE) is also called human granulocytic anaplasmosis (HGA). It is caused by the rickettsial bacteria called Anaplasma phagocytophilum (once called Ehrlichia equi or Ehrlichia phagocytophila).

Ehrlichia bacteria can be carried by the Lone Star tick, the American dog tick, and the deer tick, which can also cause Lyme disease.

In the United States, HME is found mainly in the southern central states and the Southeast. HGE is found mainly in the Northeast and upper Midwest.

Who is at highest risk?

Risk factors for Sporotrichosis include:

  • Living near an area with a lot of ticks
  • Owning a pet that may bring a tick home
  • Walking or playing in high grasses

Diagnosis

The doctor will do a physical exam and check your vital signs, including:

  • Blood pressure
  • Heart rate
  • Temperature

Other tests include:

  • Complete blood count (CBC)
  • Granulocyte stain
  • Fluorescent antibody test

When to seek urgent medical care?

Call your health care provider if you become sick after a recent tick bite or if you've been in areas where ticks are common. Be sure to tell your doctor about the tick exposure.

Treatment options

Antibiotics (tetracycline or doxycycline) are used to treat the disease. Young children should not take tetracycline by mouth until after all their permanent teeth have grown in, because it can permanently discolor growing teeth. Doxycycline used for 2 weeks or less typically does not cause discoloration of a child's permanent teeth.

What to expect (Outlook/Prognosis)?

Sporotrichosis is rarely deadly. With antibiotics, patients usually improve within 24 - 48 hours. Recovery takes 3 weeks.

Possible complications

Prevention of Sporotrichosis

Sporotrichosis is spread by tick bites. Preventing tick bites will prevent this, and other, tick-borne diseases. Common measures to prevent tick bites include:

  • Avoiding dense brush and long grasses when hiking
  • Checking yourself for ticks and removing any that you find after being outside
  • Not standing under trees or bushes
  • Using insect repellent
  • Wearing clothing to cover skin

Studies suggest that a tick must be attached to your body for at least 24 hours in order to cause disease, so early removal will prevent infection. If you are bitten by a tick, write down the date and time the bite happened, and bring this information, along with the tick (if possible), to your doctor if you become sick.
