Set-up description and genome pointers out-of K. michiganensis BD177
Performance
1.3 Gbp) were processed to remove SMRT bell adapters, short and low-quality reads (< 80% accuracy) using SMRT Analysis version 2.3 ( A total of 155,828 filtered reads (average length, 8.9 Kb) were used for de novo assembly using Celera Assembler , with self-correction of the PacBio reads. A total of 1091 Mb paired-end Illumina reads screened from a 500-bp genomic library were mapped using SOAP to the bacterial plasmid database for tracing the presence of any plasmid and filling the gaps. The de novo assembly resulted in five contigs, representing the K. michiganensis BD177 complete genome of 6,812,698 bp with GC content % in a single chromosome and four plasmids. The annotated genome contains 6714 genes, 25rRNA genes, and 86 tRNA genes (Table 1).
16S rRNA https://datingranking.net/tr/ferzu-inceleme/ phylogenetic investigation and you can phenotypic of remote strain BD177
Restriction parsimony based and limit opportunities phylogenetic trees with the sequence that encodes to the 16S rRNA gene showed that this new nearest species so you can BD177 are K. michiganensis and you may K. oxytica (Extra file step 1: Fig. S1, Even more document 2: Dining table S1). Evolutionary divergence point regarding 16S rRNA gene succession anywhere between BD177 and K. michiganensis E718 try minimum value (BD177 compared to K. michiganensis E718: 0.0079) certainly the sequences. Biochemical assessment were performed into BD177 by API20E to verify their status on the K. oxytoca and you may K. michiganensis. Biochemical functions of K. oxytoca ATCC13182(T)(=NCTC13727) and K. michiganensis W14(T)(= DSM2544) was in fact obtained from BacDive Webservices pared with K. oxytoca ATCC13182(T) and you may K. michiganensis W14(T), BD177 is the same which have W14 on ?-galactosidase chemical positive and urease bad, exact same that have ATCC13182(T) in the arginine dihydrolase positive. Although not, BD177 doesn’t have use feature of citrate since merely carbon resource, unlike one another variety of challenges (Dining table 2).
Pan-genome investigation
In this study, we considered the 128 publicly available genome assemblies for the Klebsiella sp. (Additional file 3: Table S2). Of these genomes, 26 were originally annotated as K. aerogenes, 13 were K. michiganensis, 27 were K. oxytoca, and 15 were K. pneumoniae. 25 were K. quasipneumoniae, 1 was K. quasivariicola, 21 were K. variicola. The type strain genome of each species is included in these genomes. These genome assemblies were passed strict quality control (N75 values of > 10,000 bp, 90% completeness and < 5% contamination) by quast and checkm (Additional file 4: Table S3). This resulted in a total of 118 Klebsiella sp. strains studied, where ten low-quality genome assemblies were discarded. The GC contents of the species K. michiganensis, K. oxytoca, K. pneumoniae, K. variicola, and K. quasipneumoniae showed low intraspecies variation, with respective average values of , , , and % (Fig. 1a), whereas larger interspecies diversity was observed. In contrast, K. aerogenes genomes can be divided into two groups, a large group showing a GC content in the range of that of Klebsiella aerogenes ( to %) and a small group of two genomes ( and %) showing a much greater GC content, similar to that of the K. pneumoniae, K.variicola and K. quasipneumoniae genomes (respective average values about 57%). Based on GC content of the genome, K. pneumoniae, K.variicola, K. quasivariicola, and K. quasipneumoniae were considered as a high GC group content, and K. michiganensis and K. oxytoca were considered as a low GC content group. The genome sequence of our new isolate, which we designated K. michiganensis BD177 with % GC content (Table 1), shows a similar to that of the low GC content Klebsiella sp. group (Fig. 1a).
