Comparative transcriptome analysis reveals metabolic differences between planktonic and biofilm of Actinobacillus pleuropneumoniae.

(Submitter supplied) To reveal the transcriptional profiles of Actinobacillus pleuropneumoniae under biofilm and planktonic growth, we established a biofilm-forming culture method and constructed a mutant strain Δpga with defect in biofilm formation. Wild-type and Δpga mutant strains of Actinobacillus pleuropneumoniae strain 4074 were cultured in bottles with shaking for planktonic (WT_PK) and in microplates in static status for biofilm (WT_BF, Δpga), respectively. more...

Effects of two-component system NarQ/P deletion on gene expression of Actinobacillus pleuropneumoniae in nitrate-rich anaerobic growth

(Submitter supplied) Nitrate metabolism is an adaptation mechanism used by many bacteria for survival under anaerobic environments. As a by-product of inflammation, nitrate is used by the intestinal bacterial pathogens to enable gut infection. However, the responses of bacterial respiratory pathogens to nitrate are less well understood. Actinobacillus pleuropneumoniae is an important bacterial respiratory pathogen of swine. more...

Expression profiles of Actinobacillus pleuropneumoniae 4074 and the qseB/qseC gene-deleted mutant

(Submitter supplied) To determine the role of Actinobacillus pleuropneumoniae two-component system QseBQseC, we constructed a qseBqseC gene-deleted mutant ΔqseBΔqseC based on the wild type A. pleuropneumoniae 4074. The transcriptional profiles were compared between the A. pleuropneumoniae ΔqseBΔqseC and its parental strain under the normal growth condition using microarray. A total of 44 genes were found differentially expressed (DE) compared to the wild type strain. more...

Expression data of Actinobacillus pleuropneumoniae 4074 under aerobic and anaerobic environment

(Submitter supplied) Actinobacillus pleuropneumoniae is an important porcine respiratory pathogen causing great economic losses in the pig industry worldwide. Oxygen deprivation is a stress that A. pleuropneumoniae will encounter during both early infection and the later, persistent stage. To understand modulation of A. pleuropneumoniae gene expression in response to the stress caused by anaerobic conditions, gene expression profiles under anaerobic and aerobic conditions were compared in this study. more...

Expression data of Actinobacillus pleuropneumoniae 4074, the ΔluxS mutant and AI-2 supplemented ΔluxS mutant

(Submitter supplied) LuxS is an enzyme involved in the activated methyl cycle. The by-product of this cycle, autoinducer 2 (AI-2), could be an important quorum sensing signal. LuxS was conserved and regulated many behaviors in different bacteria, but in most species, whether the regulations are related to AI-2 mediated quorum sensing is still unknown. In our previous study, Actinobacillus pleuropneumoniae, the etiologic agent of porcine contagious pleuropneumonia, was found to possess the functional LuxS affecting biofilm formation and virulence. more...

Expression data of Actinobacillus pleuropneumoniae 4074 and the ΔluxS mutant of Actinobacillus pleuropneumoniae 4074

(Submitter supplied) LuxS is an enzyme involved in the activated methyl cycle and the by-product autoinducer 2 (AI-2) was a quorum sensing signal in some species. In our previous study, the functional LuxS in AI-2 production was verified in the porcine respiratory pathogen Actinobacillus pleuropneumoniae. Enhanced biofilm formation and reduced virulence were observed in the luxS mutant. To comprehensively understand the luxS function, in this study, the transcriptional profiles were compared between the A. more...

Transcript profiling of Actinobacillus pleuropneumoniae in BALF

(Submitter supplied) Actinobacillus pleuropneumoniae is the etiologic agent of contagious pleuropneumonia, an economically important disease of commercially reared swine throughout the world. To cause this disease, A. pleuropneumoniae must rapidly overcome porcine pulmonary innate immune defenses. Since bronchoalveolar fluid (BALF) contains many of the innate immune components found in the lung, we examined the gene expression of a virulent serovar 1 strain of A. more...
