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 investigation and phenotypic off separated filter systems BD177
Limitation parsimony dependent and you can restrict likelihood phylogenetic woods using the succession one encodes to the 16S rRNA gene revealed that new nearest variety to help you BD177 are K. michiganensis and you can K. oxytica (Most document step one: Fig. S1, Extra file dos: Dining table S1). Evolutionary divergence distance off 16S rRNA gene sequence between BD177 and K. michiganensis E718 are minimal worth (BD177 compared to K. michiganensis E718: 0.0079) one of all the sequences. Biochemical tests were performed with the BD177 because of the API20E to verify its status in the K. oxytoca and you may K. michiganensis. Biochemical attributes out of K. oxytoca ATCC13182(T)(=NCTC13727) and 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 the identical that have W14 from the ?-galactosidase chemical self-confident and you will urease bad, same that have ATCC13182(T) in arginine dihydrolase positive. But not, BD177 does not have use function from citrate given that only carbon origin, not the same as one another method of challenges (Table dos).
Pan-genome research
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 https://datingranking.net/tr/cheekylovers-inceleme/,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).
Pan-genome study of 119 genomes within studies. Genomes was grouped considering their species annotation throughout the NCBI database (except for isolate K. michiganensis BD177). a great GC articles of all the genomes was labeled predicated on their variety annotation from the NCBI databases. b pie chart of the 119 reviewed Klebsiella sp. genomes.
