Cleaning Fish Tank Can Lead to Infections
Clinical Infectious Diseases - August 1, 2003
Owners of tropical fish be warned: Cleaning the fish tank without wearing gloves may get you a bacterial skin infection, especially if you have an open cut or abrasion on your hand or a depressed immune system.
Writing in the medical journal Clinical Infectious Diseases, Dr. C. Fordham von Reyn and colleagues from Dartmouth-Hitchcock Medical Center in Lebanon, New Hampshire, describe eight adults who developed sores, mostly on the arms, after cleaning their fish tanks.
In six of the eight individuals, lab tests showed the culprit to be Mycobacterium marinum, a bacterium first identified in dead aquarium fish in 1926. This bug was found to infect humans in 1951 after being isolated from skin lesions.
The use of chlorine in swimming pools has drastically reduced the number of skin infections among swimmers. Today, most reported skin infections linked to the bacterium come from contact with fish tanks.
Antibiotic therapy took care of the infection in most cases. But one patient's infection failed to resolve after about two years of drug treatment as well as attempts to cut out the sores. This patient had a depressed immune system. He had psoriasis, melanoma, and was taking steroids.
Fish-tank exposure is the source of "most cases" of M. marinum skin infections, the researchers warn, and may be preventable by using waterproof gloves.
