Occurrence of Nasal Nosocomial Myiasis by Lucilia sericata (Diptera: Calliphoridae) In North of Iran.

We report a case of human nasal nosocomial myiasis in a 69-year-old rural man with numerous live maggots in nostrils. The patient was admitted in Emergency Ward due to dyspnea. After 72 hours the companion of patient discovered larva. The presence of the third instar larva indicated that the infestation was not more than three days. The collected instars were cleared, fixed and morphological studies then were carried out precisely and the larva was identified as Lucilia sericata.
