RESUMO
INTRODUCTION: Live maggot infestation (myiasis) of wounds can present a host of ailments. Loosely associated with maggot excreta, Morganella morganii is a widespread, gram-negative rod bacterium commonly found in the intestinal tracts of humans. M morganii has been observed as being pathogenic, particularly in nosocomial and postoperative environments, as well as in immunosuppressed and elderly populations. CASE REPORT: Herein, the authors present a rare, previously unreported case of M morganii septicemia (as confirmed by positive blood culture), secondary to myiasis of the lower extremities. The patient was successfully treated with both systemic and topical interventions. Posttreatment examination revealed resolution of myiasis and negative blood cultures. CONCLUSIONS: Myiasis can be invasive, leading to severe systemic infection. In these cases, a broad-spectrum antibiotic combined with systemic and topical antiparasitic therapy should be considered.
