Genomic diversity of Taylorella equigenitalis introduced into the USA from 1978 to 2012

PMCID: 5870977
PMID: 29584782
DOI: 10.1371/journal.pone.0194253

[…] 15kb-20kb insert size (bluepippin kit) and sequenced on an rs ii (pacific biosciences, menlo park, ca) with 2 smrt cells per sample., short-read sequences were de novo assembled using abyss [] for ksnp analysis. pacbio reads were assembled using hgap version 2.0 with the default parameters []. canu version 1.4 was also used to assemble raw pacbio reads []. mauve was used to align the output […]


Expansion of a urethritis associated Neisseria meningitidis clade in the USA with concurrent acquisition of N. gonorrhoeae alleles

PMCID: 5834837
PMID: 29499642
DOI: 10.1186/s12864-018-4560-x

[…] gonorrhoeae sequence typing for antimicrobial resistance (ng-star) [] analyses for further characterization., snp-based parsimony phylogenies (fig. ) were inferred from genome assemblies by the ksnp v3.0 pipeline []. ksnp examines all 25 bp sequences in each genome (k-mers) and reports core single nucleotide polymorphisms (snps) for all sets of k-mers that differ only at the central (i.e. […]


Whole Genome Sequencing characterization of bloodstream infection causing hypervirulent Klebsiella pneumoniae of capsular serotype K2 and ST374

PMCID: 5955473
PMID: 29338592
DOI: 10.1080/21505594.2017.1421894

[…] regularly interspaced short palindromic repeats) arrays were identified by pilercr []., genome-wide single nucleotide polymorphism (snp) calling and phylogenetic analysis was performed by using ksnp v3 []. the 106 completely sequenced k. pneumoniae genomes, including rjf293 sequenced in this study, were downloaded from ncbi genome (supplementary table s3). the phylogeny scheme was generated […]


Comparative genomic analysis of ten clinical Streptococcus pneumoniae collected from a Malaysian hospital reveal 31 new unique drug resistant SNPs using whole genome sequencing

PMCID: 5815235
PMID: 29448938
DOI: 10.1186/s12929-018-0414-8

[…] of minimum edge weight set to 5 and the minimum edge density (total number of edges / theoretical number of edges) set to 0.35., single nucleotide polymorphisms (snps) were identified using ksnp3 program (version 3.021) which identifies pan-genome snps in a set of genome sequences and builds a phylogenetic tree based on the snps []. ksnp3 was run using the standard mode of snp detection […]


Phenotypic and Genotypic Analysis of Antimicrobial Resistance among Listeria monocytogenes Isolated from Australian Food Production Chains

PMCID: 5852576
PMID: 29425131
DOI: 10.3390/genes9020080

[…] in australia, such as st1, st2, st3, st155, and st204 []. a list of amr genes used in blast searches is presented in ., the single-nucleotide polymorphism (snp) phylogeny was determined with ksnp v3.1 [] for 79 isolates using a mixture of finished genomes, draft genomes, and read data. paired-end read files were quality filtered, converted to fasta and merged using seqtk v1.2–r102 […]


Invasive bacterial disease trends and characterization of group B streptococcal isolates among young infants in southern Mozambique, 2001–2015

PMCID: 5774717
PMID: 29351318
DOI: 10.1371/journal.pone.0191193

[…] 1.8.1 and draft genome assemblies were constructed using velvetoptimiser v 2.2.5 with an optimal kmer value calculated by velvetk. core genome snp identification and alignment were carried out using ksnp3.0[]., microbiologically-confirmed ibd was defined as a positive blood or csf culture from a young infant from the dss catchment area admitted to mdh. coagulase-negative staphylococci, group […]
