MetabolomicsAnalysis of Growth Phases of Enterotoxigenic Escherichia coli Reveals a Distinct Transition Phase before Entry into Early Stationary Phase with Shifts in Tryptophan, Fucose, and Putrescine Metabolism and Degradation of Neurotransmitter Precursors

Enterotoxigenic Escherichia coli (ETEC) is a major cause of diarrhea in children and adults in endemic areas. Gene regulation of ETEC during growth in vitro and in vivo needs to be further evaluated, and here we describe the full transcriptome and metabolome of ETEC dur...

MetabolomicsTranscriptional Shift and Metabolic Adaptations during Leishmania Quiescence Using Stationary Phase and Drug Pressure as Models

Microorganisms can adopt a quiescent physiological condition which acts as a survival strategy under unfavourable conditions. Quiescent cells are characterized by slow or non-proliferation and deep down-regulation of processes related to biosynthesis. Although quiescence has been described mostly...

TranscriptomicsTranscription profiling of three Bordetella bronchiseptica strains at three distinct phases of growth: mid-log phase, late-log phase, and late-stationary phase
Microarray analysis was performed to determine if the growth-dependent gene expression changes occurred on a global scale for B. bronchiseptica strains RB50, RB53, and RB54. For this analysis cDNA representing three distinct phases of growth: mid-log phase (15H), late-log phase (24H), and late-stati...

ProteomicsProteomic Analysis of Stationary Growth Stage and Nutritional Deficiency Adaptation Reveals Brucella Abortus Virulence Mechanisms
Brucellosis, an important bacterial zoonosis caused by Brucella species, has drawn increased attention around the world. As an intracellular pathogen, the ability of Brucella to deal with stress within the host cell is closely related to its virulence. The survival pressure on Brucella within a phag...

TranscriptomicsBrucella melitensis global gene expression
In this study we report that B. melitensis at the late logarithmic phase of growth are more invasive for HeLa cells than at mid logarithmic or stationary growth phases. Microarray analysis of B. melitensis gene expression identified 414 up- and 40 down-regulated genes in late-log growth phase compar...
