Paper text:
nematodes are very diverse , with entomopathogenic nematodes ( epns ) receiving a lot of interest in nematology and entomology studies because of their ability to infect and kill insects 

 .
epns reside naturally in the soil and are obligate parasites of a wide variety of insect species .
three genera of epns which are able to fulfill the role of vectors for entomopathogenic bacteria have been identified and reported on so far .
their ability to infect insects is dependent on their symbiotic association with pathogenic bacteria belonging to the genera photorhabdus , xenorhabdus , and serratia , respectively 
 , , , .
the oscheius genus was acknowledged as an independent genus 

  and later 

  supported the recognition of oscheius as an autonomous genus .
examples of described oscheius species include oscheius maqbooli 

 , oscheius shamimi 

 , oscheius carlianonsis 

  and oscheius amsactae 

 .
not all nematodes belonging to the oscheius genus are entomopathogenic 

  such as o. insectivorus .
this may be due to the absence of a symbiotic pathogenic bacteria association , which is the main characteristic of insect - killing nematodes .
several insect pathogenic strains or species of serratia bacteria have also developed successful endosymbiotic relationships with some nematodes belonging to the caenorhabditis and oscheius species 
 , .
for example , serratia species scbi associated with caenorhabditis briggasae isolated from south africa in the kwazulu - natal province was found to have entomopathogenic potential as it caused mortality of the insect larvae galleria mellonella 

 . in this paper
the infective juveniles of this entomopathogenic nematode were collected from freshly prepared white traps and surface sterilised with 0.1% sodium hypochlorite for 3  h in sterile 1.5  ml eppendorf tubes .
the nematodes were rinsed 3 times with sterile distilled water under sterile conditions in a laminar flow hood .
whole genomic dna was extracted from the sterile nematodes using a protocol adopted from puregene dna purification kit , gentra systems 2003 .
0.5% agarose gel was prepared in order to confirm the quality and integrity of the extracted dna .
a polymerase chain reaction was employed to amplify the 18s rdna region using tw81 forward primer 5-gcggatccgtttccgtaggtgaacctgc -3 , tm ( c )  =  71.94 and ab28 reverse primer 5-gcggatccatatgcttaagttcagcgggt -3 , tm ( c )  =  68.87 .
the sequence obtained was subjected to ncbi blast under the default settings for highly similar alignments .
the analysis revealed that among all the matches for the 18s rdna gene sequences , the unknown sequence differed sufficiently from other submissions and thus the species was registered as a novel entomopathogenic nematode based on the originality of the 18s rdna sequence .
a phylogenetic tree was constructed using mega 6 to show the evolutionary relationship of oscheius sp .
tel-2014 with selected species from genera oscheius , steinernema and heterorhabditis shown in 
 fig . 1 
 .
genomic dna paired - end libraries were generated with the nextera dna sample preparation kit ( illumina ) and indexed using the nextera index kit ( illumina ) .
paired - end ( 2 * 125  bp ) sequencing was performed on a illumina hiseq 2500 using the illumina sbs v4 chemistry at the agricultural research council biotechnology platform .
quality control was done using fastqc version 0.11.3 and adapter trimming was performed using trimmomatic version 0.32 .
quast version 3.1 was used for the assessment of the assembly and busco version 1.1 was used to assess the completeness of the assembly .
the n50 value was 3 019 and the total genome size was 110,599,558  bp , which is on the same size range as caenorhabditis elegans .
the genome might contain some amount of novel genes and genomic regions which busco would not have been able to align to the reference sequence of c. elegans .
retroelements , long terminal repeats ( ltr elements ) , dna transposons , small rna , satellites and simple repeats were some of the features identified .
49 947 genes were predicted using blastx and augustus version 2.5.5 protein sequences of the predicted genes were subjected to swissprot and ncbi blastp to identify the proteins .
these gene prediction and protein identification tools have revealed the presences of protein domains , hypothetical protein and other proteins also found in nematodes .
for example , the wd40 repeat domain ( 
 fig . 2 
 ) was predicted and found on position 5208 ( start ) to 5385 ( end ) .
this protein was identified from haemonchus contortus also known as barber pole worm which also belongs to the phylum nematoda , chromadorea , rhabditida . another protein predicted in oscheius sp .
topoisomerase ii large subunit originally found in escherichia phage pbeco 4 was predicted to be present i the oscheius nematodes genome .
the toprim superfamily also comprises of numerous atp - binding proteins such as histidine kinase , dna gyrase b , topoisomerases , heat shock protein hsp90 , phytochrome - like atpases and dna mismatch repair proteins ( 
 fig . 3 
 ) .
the heat shock protein hsp90 may be hypothesised to be involved in desiccation tolerance of these entomopathogenic nematodes .
the genome data described in the present study offers a valuable platform for future studies of oscheius nematodes and possesses momentous importance in the agricultural industries and scientific research .
