TranscriptomicsExpression from Staphylococcus aureus strain USA300-lac during low and 2M NaCl exposure
S. aureus has the propensity to survive a range of NaCl challenge conditions We used commercially available Affymetrix S. aureus GeneChips (part number 900514) to compare the gene expression properties of wild type cells during growth at no or high (2M) NaCl. S. aureus strain USA300-lac cells were g...

TranscriptomicsGlobal transcriptome analysis of Staphylococcus aureus biofilms in response to innate immune cells
S. aureus biofilms are associated with the organism's ability to cause disease. Biofilm associated bacteria must cope with the host's innate immune system. We used commercially available Affymetrix S. aureus GeneChips to compare the gene expression properties of 4 and 6 day established biofilms fol...

TranscriptomicsExpression Data from Brucella abortus strain 2308 and isogenic vtlR mutant cells
VtlR (virulence-associated transcriptional LysR-family regulator) is thought to be a transcriptional regulator of B. abortus virulence determinants We used custom-made Affymetrix B. abortus strain 2308 derived GeneChips to compare the gene expression properties of wild type and isogenic vtlR mutant ...

TranscriptomicsStaphylococcus aureus gene expression in a rat model of infective endocarditis
S. aureus has a propensity to cause endocarditis; diabetes mellitus is a frequent underlying comorbitity in patents with S. aureus endocarditis. S. aureus Affymetrix GeneChips were used to compare S. aureus expression properties in cardiac vegatations isolated from diabetic and nondiabetic rats. S. ...

TranscriptomicsAn Ribonuclease T2 Family Protein Modulates Acinetobacter baumannii Abiotic Surface Colonization
A. baumannii has the propensity to colonize abiotic surfaces and this is thought to mediate its transmission to susceptible patients. We found that disruption of A. baumannii ribonuclease T2 family protein (ATCC 17978 locus A1S_3026) severely diminishes the organism's ability to colonize abiotic sur...

TranscriptomicsExpression Data from Brucella abortus strain 2308 and isogenic mucR mutant cells
MucR is one of the few transcriptional regulatory proteins that has been linked to Brucella pathogenesis. We used custom-made Affymetrix B. abortus strain 2308 derived GeneChips to copare the gene expression properties of wild type and isogenic mucR mutant cells. B. abortus strain 2308 or mucR mutan...

TranscriptomicsExpression Data from Acinetobacter baumannii strain ATCC 17978 and isogenic lpsB mutant cells
lpsB encodes a glycosyltransferase involved in lipopolysaccharide (LPS) synthesis. LPS is a major component of the Gram-negative bacterial outer membranes. We used custom-made Affymetrix A. baumannii strain ATCC 17978 derived GeneChips to compare the gene expression properties of wild type and isog...

TranscriptomicsExpression Data from Brucella abortus strain 2308 and isogenic abcR1 abcR2 mutant cells
abcR1 and abcR2 produce two regulatory RNA molecules, that are produced during stationary phase growth. We used custom-made Affymetrix B. abortus strain 2308 derived GeneChips to compare the gene expression properties of wild type and isogenic abcR1 abcR2 double mutant cells. B. abortus strain 2308 ...

TranscriptomicsCharacterization of Calprotectin treated medium
The goal of this study is to correlate the transcriptional response of S. aureus cells grown in Calprotectin treated medium with that of cells grown in Mn or Zn depletion conditions. Keywords: RNA sample Staphylcoccus aureus strain Newman was grown to mid-log phase in Calprotectin treated medium or ...

TranscriptomicsExpression and mRNA half-life data of acid and alkaline shocked Staphylococcus aureus
Staphylococcus aureus is a leading cause of hospital- and community-associated infections. The organism’s ability to cause disease can, in part, be attributable to its ability to adapt to otherwise deleterious host-associated stresses. Like other bacterial species, the modulation of mRNA turnover ...
