REYES PARRADO, Adriana et al. Larval therapy with Musca domestica in the treatment of leishmanian ulcer in a murine model. Acta biol.Colomb. [online]. 2020, vol.25, n.1, pp.82-95. ISSN 0120-548X.  https://doi.org/10.15446/abc.v25n1.77177.

Leishmaniasis is a disease with significant impact on public health, given the characteristics of the tegumentary lesions. Experimental treatment with larval therapy (LT) has shown its potential use for the cure of leishmaniosis. However, fly species not easy to collect and/or colonize have been used. The objective of the present work was to use a fly of accessible collection and high fecundity, not a producer of human myiasis, such as Musca domestica. A qualitative-quantitative study of a descriptive type was carried out through an experimental design with an animal model (Mesocricetus auratus) with infection by Leishmania amazonensis to evaluate the therapeutic effect of LT and compare the results with the antimonial chemical treatment of the drug experimental "Ulamina". Scarring were observed with the use of LT in 66.66 % with TL-simple and 100 % with TL-combined. However, the combined use of LT + Ulamina, shows an enhancing effect of the clinical cure of the lesions, but with persistent inflammation. Optimal effectiveness of TL with M. domestica was observed on the ulcers; however, an effect on L. amazonensis was not observed given the presence of amastigotes in the smears and the 480 bp amplicons from the tissue of the ulcers of animals.
