Furunculoid myiasis in a dog caused by Cordylobia anthropophaga

Two days after returning with its owners from a 60-day visit to Liberia, an 8-year-old 6.5-kg spayed female Miniature Schnauzer was examined by a veterinarian in the United States. A 1.0 x 1.0-cm raised erythematous nodule was noticed on the medial aspect of the right pinna. In the center of the nodule was a 1.0 x 1.0-mm pore from which a 0.5 x 0.5 x 1.0-cm white larva was extracted. The larva was identified as a third-stage larva of Cordylobia anthropophaga, the African Tumbu fly, a fly restricted to sub-Saharan Africa. Cordylobia anthropophaga does have zoonotic potential, but the owners did not have any skin lesions. Detection of C anthropophaga in the United States warranted reports to state and federal authorities and personnel at the Centers for Disease Control and Prevention. The situation described here illustrated the potential of tourists' pets to import foreign diseases.
