Es, referred to henceforth as Leishmania macropodum sp. nov Barratt, Kaufer Ellis 207.Insect identificationTrapped midges and flies had been identified together with the help of keys and descriptions [20, 247]. Fly specimens were dissected and mounted employing the method described by Craig et al. [28]. In some cases, DNA was extracted from flies for barcoding purposes prior to identification by morphology. A DNA extraction technique described by Lawrence et al. [29] (S File) was employed that conserved the exoskeleton for downstream morphological identification.Cultivation of parasites from insectsInsects had been pooled and crushed using a spatula in 200 L of PBS. The resulting suspension was used to inoculate a Leishmania culture medium based on the medium previously described by Dougall et al. [20]. The parasite cultures obtained were initially contaminated having a Fusarium sp. fungus. As the parasite cells outnumbered the fungi, the cultures have been axenised by serial dilution such that the fungi were diluted out resulting inside a pure promastigote culture. To facilitate downstream promastigote counting experiments, a liquid medium was developed and optimised to establish the perfect haemoglobin content (S File).Light microscopy and transmission electron microscopyTo examine the morphology of cultured promastigotes, a Leishman stain was performed (SigmaAldrich) on celldense promastigote cultures, in accordance with the manufacturer’s guidelines. Cell morphology was examined by oil emersion light microscopy (000X magnification) applying a Leica DM000 microscope (Leica Microsystems). To examine their ultrastructural options, cultured promastigotes have been embedded in low melting point agarose and ready for transmission electron microscopy employing normal procedures (S File).

The supernatant was discarded and DNA was extracted in the pellet employing an EZ DNA tissue extraction kit (QIAGEN) in addition to a BioRobot EZ DNA extracting robot (QIAGEN) in accordance with the manufacturer’s directions. The DNA was eluted in a volume of 50 L for downstream PCR evaluation. PCR primers have been made to amplify the 8S rRNA gene and three protein coding genes; the glycosomal glyceraldehyde 3phosphate dehydrogenase (gGAPDH), RNA polymerase II largest subunit (RPOIILS), and heat shock protein 70 (HSP70) genes (Table 2). To create PCR goods from insects for barcoding purposes, a set of previously published primers were used to amplify fragments in the cytochrome C oxidase subunit I (COI) and II (COII) genes, the 8S rRNA gene, along with the 28S rRNA gene (Table two). Every PCR was prepared making use of reagents offered inside the BIOTAQ PCR Kit (Bioline) (S File). The PCR goods wer.
