Novel Use of Antifungal Nail Lacquer to Treat Candida Bill Infections in Ducks

Captive wild ducks in the research colony at the USGS Eastern Ecological Science Center, Laurel, Maryland USA frequently contract Candida infections on the upper and lower bills. Various standard treatments were attempted with mixed success. Several of the Surf Scoters, especially, suffered extreme erosions of the bill leading to euthanasia prior to using this new treatment. For the past 3 years we have been using a human medical product, ciclopirox 8% nail lacquer to treat the Candida successfully. The treatment requires careful trimming and debriding of the dead tissue before applying the ciclopirox, then keeping the ducks caged away from water for 15 minutes to allow the product to dry. Standard treatment is twice weekly. For persistent cases we add oral fluconazole to the treatment regime. We have successfully treated common eider, surf scoter, white-winged scoter, black scoter, long-tailed ducks, and harlequin ducks with ciclopirox and have seen no adverse reactions.
