A Survey on Inhibitory Effect of Whole-Body Extraction and Secretions of Lucilia sericata's Larvae on Leishmania major In vitro

BACKGROUND: Leishmaniasis is a skin disease caused by Leishmania parasite. Despite being self-limiting, must be treated. Available drugs have side effects and drug resistance has also been seen. MATERIALS AND METHODS: Maggot debridement therapy (MDT) is using sterile fly larvae (maggots) of blow flies (Lucilia sericata) for the treatment of different types of tissue wounds. Larvae have excreted and secreted substances that have been proved to have antimicrobial effects, in addition to the some other specifications. RESULTS: In this study, the anti-leishmanial effects of extracts and secretions of sterile second- and third-instar larvae of L. sericata on the growth of Leishmania major promastigotes and amastigotes in the J774 macrophages have been evaluated in vitro. CONCLUSION: The results showed that extracts and secretions had almost the same leishmaniocidal effect on promastigotes and intracellular amastigotes without cytotoxic effect on macrophages.
