Seal finger

Seal Finger

Seal finger, also known as sealer's finger, is an infection that occurs in humans after handling seals or seal products. This condition is caused by a specific type of bacteria that is found in the mouths of seals. It is a rare zoonotic disease, meaning it is transmitted from animals to humans.

Etiology

Seal finger is primarily caused by the bacterium *Mycoplasma phocacerebrale*. This bacterium is part of the normal oral flora of seals. Humans typically contract the infection through cuts or abrasions on the skin that come into contact with the bacteria while handling seals, seal pelts, or other seal products.

Clinical Presentation

The symptoms of seal finger usually begin with swelling, redness, and pain in the affected finger or hand. The infection can lead to joint stiffness and, if left untreated, may progress to more severe conditions such as arthritis or tenosynovitis. In some cases, the infection can spread to other parts of the body.

Diagnosis

Diagnosis of seal finger is primarily clinical, based on the patient's history of exposure to seals and the characteristic symptoms. Laboratory tests can be used to identify the presence of *Mycoplasma phocacerebrale* in samples taken from the infected area.

Treatment

Treatment of seal finger typically involves the use of antibiotics. Tetracycline and doxycycline are commonly used antibiotics that have been effective in treating this infection. In some cases, surgical intervention may be necessary to drain abscesses or to relieve joint stiffness.

Prevention

Preventive measures include wearing protective gloves and clothing when handling seals or seal products. It is also important to clean and disinfect any cuts or abrasions immediately after exposure to potentially contaminated materials.
