Lucilia sericata, a member of the Calliphoridae family, is one of the most common species in the genus Lucilia. Medical importance of L.serkata stems from its use in maggot debridement therapy (MDT). MDT is the name of L.sericata larvae being sterilized and used in the treatment of non-healing wounds. L.sericata maggots used in the treatment of chronic and non-healing wounds (decubitus ulcer, venous leg ulcer, diabetic foot ulcer, etc.) clean the wounds with the help of secreted proteolytic trypsin and lucimycin-like enzymes. The aim of the study was to determine the molecular characterization of lucimycin gene obtained from L.sericata larvae in MDT by using molecular methods and to contribute to the literature. In this study, continuous production of adult colonies of L.sericata species was carried out in insectarium unit where conditions such as light, humidity and temperature were formed. The life cycle of L.sericata was followed and the production of eggs, larvae, pupae, adult flies and fly colonies of the species were formed. In the third stage larvae obtained from adult flies in the insectarium unit, RNA was isolated and subsequently cDNA synthesis was performed by reverse transcription. Polymerase chain reaction (PCR) analysis of the synthesized cDNAs with the specific primers designed for the lucimycin gene of L.sericata was performed and the obtained amplicons were cloned into pJET1.2/blunt vector and the plasmid was purified. The recombinant plasmids were sequenced with vector-specific primers and target gene region sequences were obtained. After the molecular characterization of the isolate with nucleotide sequences was determined, it was registered to GenBank database with the accession number MF964229. The PCR product of 288 bp was obtained from the cDNA obtained from the larvae of L.sericata produced in the insectarium unit by PCR using lucimycin specific primers. The PCR product imaged on the gel was purified by transformation and subsequent colonies were screened to see whether they contained recombinant plasmids. Three of the colonies were identified as recombinant plasmids containing L.sericata lucimycin gene by PCR screening. From three colonies confirmed by PCR screening, recombinant plasmids containing L.sericata lucimycin gene were purified by miniprep. The recombinant plasmid product was confirmed to contain the L.sericata lucimycin gene by PCR from a total of 20 mu l of the recombinant plasmid miniprep product. DNA sequencing analysis was performed to confirm the plasmid after cloning. The 288 bp L.sericata lucimycin sequence was confirmed by DNA sequence analysis. The lucimycin gene isolated was confirmed by specific and pJET1.2 forward and reverse primers using Blastn algorithm as a result of species and/or subspecies using the Blastn algorithm and the related isolate was recorded in GenBank database with the MF964229 accessory number. The DNA sequence of the isolated sample was compared with other isolates found in GenBank by Pubmed/Blast program. KJ413251.1 was found to be 99% similar to the GenBank isolate. The 113th nucleotide was C (cytosine) in the sequence of our isolate, while the existence of G (guanine) in the sequence numbered KJ413251.1 GenBank revealed the difference between the two sequences. In this study the molecular characterization of lucimycin gene derived from L.
