TranscriptomicsComparative Genomic Analysis of Clinical Strains of Campylobacter jejuni from South Africa
Background. The bacterial foodborne pathogen Campylobacter jejuni is a common cause of acute gastroenteritis and is also associated with the postinfectious neuropathies, Guillain-Barré and Miller Fisher syndromes. This study described the use of multilocus sequence typing and DNA microarrays to e...

TranscriptomicsNucleases Encoded by Integrated Elements CJIE2 and CJIE4 Inhibit Natural Transformation of Campylobacter jejuni
The species Campylobacter jejuni is naturally competent for DNA uptake; nevertheless, nonnaturally transformable strains do exist. For a subset of strains we previously showed that a periplasmic DNase, encoded by dns, inhibits natural transformation in C. jejuni. In the present study, genetic factor...

TranscriptomicsCulture of Campylobacter jejuni with Sodium Deoxycholate induces Virulence Gene Expression
C. jejuni, a spiral-shaped gram-negative bacterium, is a leading bacterial cause of human foodborne illness. Acute disease is associated with C. jejuni invasion of the intestinal epithelium. Further, maximal host cell invasion requires the secretion of proteins termed Campylobacter invasion antige...

TranscriptomicsGrowth phase-dependent activation of the DccRS regulon of Campylobacter jejuni
Two-component systems are widespread prokaryotic signal transduction devices which allow the regulation of cellular functions in response to changing environmental conditions. The two-component system DccRS (Cj1223-Cj1222) of Campylobacter jejuni is important for the colonization of chickens. Here w...

TranscriptomicsEscherichia coli O157:H7 Isolates Related to the 2006 Spinach-associated Outbreak Exhibit Distinct Transcriptional Profiles
We compared the transcriptional profiles of 12 E. coli O157:H7 isolates grown to stationary phase in LB broth. These isolates possess the same two enzyme PFGE profile and are related temporally or geographically to the above outbreak. These E. coli O157:H7 isolates included three clinical isolates, ...

TranscriptomicsRcsB contributes to the distinct stress fitness between Escherichia coli O157:H7 curli variants of 1993 Hamburger-associated outbreak strains
Curli are adhesive fimbriae of Enterobactericaeae and are involved in surface attachment, cell aggregation and biofilm formation. We previously reported that natural curli variants of E. coli O157:H7 (EcO157) displayed distinct acid resistance; however, this difference was not linked to the curli fi...

TranscriptomicsRegulation of Energy Metabolism by the Extracytoplasmic Function (ECF) ? factors of Arcobacter butzleri
The extracytoplasmic function (ECF) ? factors are fundamental for bacterial adaptation to distinct environments and for survival under different stress conditions. The emerging pathogen Arcobacter butzleri possesses seven putative pairs of ?/anti-? factors belonging to the ECF family. Here, we repor...
