Investigation of a Candida guilliermondii Pseudo-outbreak Reveals a Novel Source of Laboratory Contamination.

James E Kirby, Westyn Branch-Elliman, Mary T LaSalvia, Lorinda Longhi, Matthew MacKechnie, Grigoriy Urman, Linda M Baldini, Fatima R Muriel, Bernadette Sullivan, David S Yassa, Howard S Gold, Trevor K Wagner, Daniel J Diekema, Sharon B Wright,

<i>Candida guilliermondii</i> was isolated from sterile specimens with increasing frequency over a several-month period despite a paucity of clinical evidence suggesting true <i>Candida</i> infections. However, a health care-associated outbreak was strongly considered due to growth patterns in the microbiology laboratory that were more consistent with true infection than environmental contamination. ...

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 >>

Branched-chain amino acids are required for the survival and virulence of Actinobacillus pleuropneumoniae in swine.

Sargurunathan Subashchandrabose, Rhiannon M LeVeque, Trevor K Wagner, Roy N Kirkwood, Matti Kiupel, Martha H Mulks,

In Actinobacillus pleuropneumoniae, which causes porcine pleuropneumonia, ilvI was identified as an in vivo-induced (ivi) gene and encodes the enzyme acetohydroxyacid synthase (AHAS) required for branched-chain amino acid (BCAA) biosynthesis. ilvI and 7 of 32 additional ivi promoters were upregulated in vitro when grown in chemically defined medium (CDM) lacking ...

A subset of Actinobacillus pleuropneumoniae in vivo induced promoters respond to branched-chain amino acid limitation.

Trevor K Wagner, Martha H Mulks,

Actinobacillus pleuropneumoniae is the causative agent of a necrotizing hemorrhagic pleuropneumonia in swine. In this study, we investigate the possibility that the limitation of branched-chain amino acids is a stimulus that A. pleuropneumoniae will encounter during infection and will respond to by up-regulation of genes involved in branched-chain amino acid ...
