Comparative whole-genome mapping to determine Staphylococcus aureus genome size, virulence motifs, and clonality.

Sanjay K Shukla, Madhulatha Pantrangi, Buffy Stahl, Adam M Briska, Mary E Stemper, Trevor K Wagner, Emily B Zentz, Steven M Callister, Steven D Lovrich, John K Henkhaus, Colin W Dykes,

Despite being a clonal pathogen, Staphylococcus aureus continues to acquire virulence and antibiotic-resistant genes located on mobile genetic elements such as genomic islands, prophages, pathogenicity islands, and the staphylococcal chromosomal cassette mec (SCCmec) by horizontal gene transfer from other staphylococci. The potential virulence of a S. aureus strain is often ... Read more >>

Use of optical mapping to sort uropathogenic Escherichia coli strains into distinct subgroups.

William R Schwan, Adam Briska, Buffy Stahl, Trevor K Wagner, Emily Zentz, John Henkhaus, Steven D Lovrich, William A Agger, Steven M Callister, Brian DuChateau, Colin W Dykes,

Optical maps were generated for 33 uropathogenic Escherichia coli (UPEC) isolates. For individual genomes, the NcoI restriction fragments aligned into a unique chromosome map for each individual isolate, which was then compared with the in silico restriction maps of all of the sequenced E. coli and Shigella strains. All of ... Read more >>

Optical mapping reveals a large genetic inversion between two methicillin-resistant Staphylococcus aureus strains.

Sanjay K Shukla, Jennifer Kislow, Adam Briska, John Henkhaus, Colin Dykes,

Staphylococcus aureus is a highly versatile and evolving bacterium of great clinical importance. S. aureus can evolve by acquiring single nucleotide polymorphisms and mobile genetic elements and by recombination events. Identification and location of novel genomic elements in a bacterial genome are not straightforward, unless the whole genome is sequenced. ... Read more >>

Optical mapping as a routine tool for bacterial genome sequence finishing.

Phil Latreille, Stacie Norton, Barry S Goldman, John Henkhaus, Nancy Miller, Brad Barbazuk, Helge B Bode, Creg Darby, Zijin Du, Steve Forst, Sophie Gaudriault, Brad Goodner, Heidi Goodrich-Blair, Steven Slater,

<h4>Background</h4>In sequencing the genomes of two Xenorhabdus species, we encountered a large number of sequence repeats and assembly anomalies that stalled finishing efforts. This included a stretch of about 12 Kb that is over 99.9% identical between the plasmid and chromosome of X. nematophila.<h4>Results</h4>Whole genome restriction maps of the sequenced ...
