Overall 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 phylogenetic data and you may phenotypic from remote filter systems BD177
Maximum parsimony depending and you may restriction opportunities phylogenetic trees utilising the sequence you to definitely encodes for the 16S rRNA gene revealed that brand new closest species so you can BD177 is actually K. michiganensis and K. oxytica (Extra document step one: Fig. S1, Additional file 2: Dining table S1). Evolutionary divergence point out of 16S rRNA gene series anywhere between BD177 and K. michiganensis E718 is minimum value (BD177 vs K. michiganensis E718: 0.0079) certainly the sequences. Biochemical evaluation had been did towards the BD177 because of the API20E to verify the status on K. oxytoca and you can K. michiganensis. Biochemical attributes out-of K. oxytoca ATCC13182(T)(=NCTC13727) and you may K. michiganensis W14(T)(= DSM2544) was basically taken from BacDive Webservices pared that have K. oxytoca ATCC13182(T) and K. michiganensis W14(T), BD177 is similar which have W14 regarding the ?-galactosidase chemical positive and you may urease bad, same that have ATCC13182(T) into the arginine dihydrolase self-confident. But not, BD177 doesn’t always have the employment function from citrate since just carbon origin, distinct from both type of challenges (Table dos).
Pan-genome studies
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 livejasmin eÅŸleÅŸme sorunu 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, < 500 undetermined bases per 100,000 bases, > 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).
