Genomic Architecture of the Two Cold Adapted Genera Exiguobacterium and Psychrobacter: Evidence of Functional Reduction in the Exiguobacterium antarcticum B7 Genome

Genome Biol Evol
PMCID: 5833320
PMID: 29438502
DOI: 10.1093/gbe/evy029

[…] Tree v.4.14.2 () to obtain an unrooted tree. In the second approach, the whole nucleotide sequence of the genomes, including their plasmids, were compared all-against-all by BLASTn using the software Gegenees v.2.2.1 () with a fragment size of 200 bp and a step size of 100 bp. Fragments with identity values >30% were used to calculate the similarity scores. The result was presented as a heat map w […]


Large scale genomic analyses reveal the population structure and evolutionary trends of Streptococcus agalactiae strains in Brazilian fish farms

Sci Rep
PMCID: 5648781
PMID: 29051505
DOI: 10.1038/s41598-017-13228-z

[…] The similarity of whole genomes were compared using Gegenees software version 2.0 along with other piscine S. agalactiae strains that had complete genome sequences, 138spar (ST-261) and GD201008-001 (ST-7) (GenBank access numbers CP007565 and CP003810, […]


New Insights into the Diversity of the Genus Faecalibacterium

Front Microbiol
PMCID: 5609107
PMID: 28970823
DOI: 10.3389/fmicb.2017.01790

[…] and the diversity inside genus Faecalibacterium.A whole-genome comparative analysis further validated our findings from the 16S rRNA gene phylogeny. A whole-genome similarity matrix was obtained with Gegenees software and used for a phylogenomic analysis; the resulting phylogenetic tree agreed with the previously performed 16S rRNA analysis in identifying the same three groups of strains: clusters […]


Phylogenomics of Colombian Helicobacter pylori isolates

PMCID: 5594506
PMID: 28912838
DOI: 10.1186/s13099-017-0201-1

[…] The genomes sequenced in this study were aligned with 34 H. pylori reference strains from the National Center for Biotechnology Information (NCBI) databases using the Gegenees v2.21 tool. This tool uses an algorithm to align genomic fragments and compares them by Blastn [, ]. The fragment size was 200 bp, and the sliding step size was 100 bp. The average sequence s […]


Identification and genomic comparison of temperate bacteriophages derived from emetic Bacillus cereus

PLoS One
PMCID: 5590980
PMID: 28886124
DOI: 10.1371/journal.pone.0184572
call_split See protocol

[…] m known transcription factor binding sites were identified using Bprom ( Comparative genome analysis of the phages at the nucleotide level was conducted using Gegenees 2.1 (window size of 50 bp, step-size of 25 bp, and cutoff of 30%) and Mauve, and comparison at the proteomic level was made using CoreGenes 3.0 ( Genes […]


The Mobilome; A Major Contributor to Escherichia coli stx2 Positive O26:H11 Strains Intra Serotype Diversity

Front Microbiol
PMCID: 5592225
PMID: 28932209
DOI: 10.3389/fmicb.2017.01625

[…] er ( This application outputs a fasta file containing all predicted prophage regions (the “phageome”) for each isolate. The global “phageome” of all strains was compared using the Gegenees software (see above). The predicted prophage regions were then pairwise compared using the progressive Mauve alignment tool, EasyFig (Sullivan et al., ) and Blastn. […]
