For pull-down experiments using L. amazonensis, a Streptavidin-binding Peptide (SBP) tagging vector pX-H-SBP-H was used. This vector contains an SBP-tag flanked by two intergenic regions derived from the Hsp83 genomic cluster (denoted ‘H’), that promote expression in both life forms. Foreign genes were cloned upstream to the SBP tag. For experiments with L. major a Tandem Affinity Purification (TAP) tagging vector pSNSAP1 (21 (link)) was used, placing the tag in the C-terminus of the target gene. See Supplementary ‘Materials and Methods’ section for plasmids construction details.
Leishmania amazonensis cells were transfected as previously described (22 (link)) with pX-H-LeishIF4E1-SBP-H, pH-LeishIF4E4-SBP-H and pH-LeishIF4EIP-SBP-H and stable cell lines were selected using 100 µg/ml G-418. Leishmania major cells were similarly transfected with pSNSAP1-LeishIF4E-1 or pSNSAP1-LeishIF4E-4, and stable cell lines were selected using 200 µg/ml G-418.

To obtain high-quality clean reads, the raw reads were filtered to remove reads with adaptor sequences, low-quality reads (Phred quality score <20 bp), and reads with a high percentage of unidentified nucleotides, using Perl script with G-language Genome Analysis Environment [36 (link)]. De novo assembly of the clean reads was carried out using Trinity software (version: trinity/r2014-04-13p1) with default parameters and no reference sequence. The sequences resulting from the de novo Trinity assembly were called unigenes. In order to annotate unigenes, a BLASTX search against the UniProt database was conducted with an E-value cut-off of 1e−5. The following genomic databases were used for the taxonomic distribution of annotated components : plants (Chlamydomonas reinhardtii, http://www.ncbi.nlm.nih.gov/pubmed /17932292; Arabidopsis thaliana, https://www.arabidopsis.org/); animals (Drosophila melanogaster, http://flybase.org/; Caenorhabditis elegans, https://www.wormbase.org/); fungi (Saccharomyces cerevisiae, http://www.ensembl.org/index.html); kinetoplastids (Trypanosoma cruzi, Trypanosoma brucei, Leishmania major, http://www.ncbi.nlm.nih.gov/). A venn diagram was drawn using Venny program (http://bioinfogp.cnb.csic.es/tools/venny/). The Blast2GO program [37 (link)] and Kyoto Encyclopedia of Genes and Genomes (KEGG) database [38 (link)] (http://www.genome.jp/kegg/) were used to identify the Gene ontology (GO) annotation and biological pathways in E.gracilis, respectively. Results of pathway enrichment were visualized using Pathway Projector [39 (link)].

Five to seven week old female, Swiss and C57BL/6, mice were infected with 5000 and 1000 blood stage T. cruzi trypomastigotes, respectively [13] (link), [19] (link), [21] (link). Swiss mice infected with the T. cruzi Colombiana strain were representative of the acute phase model of CD [13] (link). C57BL/6 mice infected with the T. cruzi Colombiana strain were representative of the chronic phase model of CD [21] (link). Parasite levels were determined using light microscopy obtained via tail vein bleed [19] (link), [22] (link). The myotropic Colombiana strain and the Y strain of T. cruzi were maintained by serial passage every 21 and 10 days, in Swiss mice, respectively. The Y, Colombiana and 0704 strains of T. cruzi were cultured in-vitro using 3T3 mouse fibroblast cells [19] (link), [23] (link). Infected 3T3 cell culture supernatant was collected and concentrated to obtain the TESA fraction [19] (link). Protein extracts from parasites unrelated to T. cruzi, such as Plasmodium falciparum infected RBCs, promastigotes of Leishmania donovani, Leishmania major and Leishmania infantum were obtained as described earlier [19] (link).

Briefly, the low (1.5×103 CFU/mL) and high (1.5×106 CFU/mL) doses of each bacterium were suspended in 10 μL of PBS either with or without L. major (1.5×106/ml). Leishmania major alone and PBS were set as controls. The suspensions were injected intradermally into the right ear pinna of mice following anesthetizing with xylazine (10 mg/kg) and ketamine (80 mg/kg) (Table 1).

The reference strain of Leishmania major (MRHO/IR/75/ER) and two bacterial species of Enterobacter cloacae and Bacillus subtilis were selected for inoculum preparation. At fifth day of culture, stationary phase promastigotes of L. major were harvested from RPMI 1640 medium supplemented with 10% fetal bovine serum (Gibco Invitrogen, Carlsbad, CA, USA) and 100 μg/ml of penicillin-streptomycin (Biowest, USA) incubated at 25 ± 1°C. To count parasites, the cultures were centrifuged at 5,000 ×g at room temperature for 10 min and then re-suspended in 0.5% formalin following three washes with PBS. The reason for choosing these two bacterial species was their isolation from the resting, feeding and breeding environments of P. papatasi and their significant effects on the development of Leishmania (Maleki-Ravasan, in press ; Maleki-Ravasan et al., 2015 (link)). Both bacteria were grown at 37°C on a Brain Heart Infusion (BHI) agar medium plate overnight. The single-grown colonies were then subcultured in BHI broth at 100 rpm at 37°C overnight. Bacterial cells were adjusted to 1.5×108 CFU/ml (optical density at 600 nm, ∼0.25) according to Kaplan et al., 2012 (link) protocol. The stock solution was serially diluted up to 1:100 and 1:10,000 to obtain 1.5×106 and 1.5×103 CFU/ml of each bacterial cell for high and low doses groups, respectively.

An author's country of origin and affiliated institutions were considered to be the first information reported by the author, as manuscripts were counted as a unit of analysis. The relationship analysis was carried out using the scientometric visualization software VOSviewer 1.6.16 (https://www.vosviewer.com/) based on the structuring of the bibliographic networks and the specificities of the references associated with each record, in addition to the author's descriptor data and the arrangement of the most frequent terms in the publications.
Data were analyzed for the complete period and stratified into four periods (1991-2000, 2001-2010, 2011-2021, and 1991-2021); the change from 1991 to 2021 was then compared. To demonstrate the evolution of scientific production over time, graphs were constructed; data depicted were on the number and proportion of publications on NTDs in JBSTM and the NTDs with the highest proportion of scientific publications. Tables were organized by decades to present independent NTDs, types of scientific products, authors, descriptors, affiliations, and countries.

The amino acid sequence of Leishmania major GP63 was retrieved from the UniProt (Universal Protein Resource) knowledge base at http://www.uniprot.org/ with the accession number A0A0S2UX54 and stored in FASTA format for further analysis. After determining the degree of homology, differences among amino acid positions, and the frequency-based difference, a COBALT blast (multiple alignments) was performed with the blosum 80. The GP63 sequence was used to query the Protein Data Bank (PDB) proteins database using BLAST at http://blast.ncbi.nlm.nih.gov/Blast.cgi to discover an appropriate template structure for homology modeling predictions.

The protein structure of FeSODA and TR from Leishmania donovani is not available. However, these two proteins show very high similarity in other spices of the parasite. Accordingly, the crystal structures of FeSODA from Leishmania major (PDB ID: 4F2N) and TR from Leishmania infantum (PDB ID: 2JK6) were utilized in this study17 (link),18 (link). The protein preparation wizard, a feature of the Glide module Maestro 13.1, was used to prepare both protein structures. Preparation and refinement are the two parts of the protein preparation wizard. The protein preparation component first verifies chemical correctness, adds hydrogen, neutralizes side chains, and then assigns bond order using the Cambridge Structural Database (CSD). The protein preparation wizard was applied to form disulfide bonds, fill in missing atoms, improve side chains, and ensure the accuracy of partial atomic charges in order to produce the right structure. In the subsequent step, water molecules were removed, and a minimization process was executed until the average root mean square deviation (RMSD) of 0.3 Å for the non-hydrogen atoms was attained, employing the OPLS_2005 force field19 (link).
