[Observations of the sand flea (Tunga penetrans) in humans and dogs in French Guiana].

The occurrence of sand fleas (Tunga penetrans) in a reservation in the north of French Guyana is described. The parasite is found on dogs, Europeans and children of the local Indian tribes. Infections in man are supported by a big population of stray dogs as well as by the local cottage construction. Due to the simultaneous efficiency against the larvae of Dermatobia hominis lvermectin is only of limited suitability for the treatment of tungiasis in dogs. In man single parasites can be removed with a splinter forceps. In dogs footbathing with 0.2% Neguvon has shown to be effective. On long term a reduction of the stray dog population is recommended.
