Two Sarcophaga wound myiases in Japan: S. peregrina at a trichophytosis sore of an inpatient and S. crassipalpis in a post-surgical wound of a home convalescent

摘要

Two cases of Sarcophaga myiasis were found in Osaka Prefecture, Japan. In the first case, larvae were removed from a trichophytosis sore at the root of the toes on the right foot of a 77-yr-old woman confined to bed in a hospital and were reared in our laboratory. The adult flies which emerged were identified as S. peregrina Robineau-Desvoidy on the basis of the characteristics of adult flies. This indicates a hospital-acquired myiasis. In the second case, one larva was removed from a post-surgical wound in the face of a 72-yr-old man convalescing in his home after resection of genyantrum cancer and was reared in the laboratory; the one adult fly which emerged was identified as S. crassipalpis Macquart. The definition of myiasis is discussed and clinical characteristics of patients with wound myiases in Japan are summarized.
