(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...

(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...

(Submitter supplied) The objective of this study was to identify porcine genes which expression was affected by experimental infection with A. pleuropneumoniae within 24 hours after experimental challenge. Microarray experiments were conducted to reveal genes being significantly differentially expressed in infected versus non-infected lung tissue and in liver and lung lymph node tissue from three challenged versus two non-challenged animals. more...

(Submitter supplied) To better understand effects of iron starvation on A. pleuropneumoniae and to identify new potential vaccine targets, we conducted transcript profiling using a DNA microarray containing all 2025 ORFs of the genome of A. pleuropneumoniae serotype 5b strain L20. Upon comparing growth of this pathogen in iron-sufficient versus iron-depleted medium, 210 genes were identified as being differentially expressed. more...

(Submitter supplied) The transcriptional profile of the porcine lung pathogen, Actinobacillus pleuropneumoniae, was monitored during the acute phase of infection in its natural host. Bacterial expression profiles of A. pleuropneumoniae isolated from lung lesions of 25 infected pigs were compared in samples taken 6, 12, 24 and 48 hours post infection.

(Submitter supplied) Host-pathogen interactions are of great importance in understanding the pathogenesis of infectious microorganisms. We developed in vitro models to study porcine respiratory tract pathogens using an immortalized epithelial cell line, the St. Jude Porcine Lung (SJPL) cell line. In conditions where cytotoxicity was absent or low, the transcriptomic profile of A. pleuropneumoniae after contact with the porcine lung epithelial cells was determined using DNA microarrays. more...

(Submitter supplied) Acute pleuropneumonia in swine, caused by Actinobacillus pleuropneumoniae (APP), is characterized by a high and sustained fever. Fever creates an adverse environment for many bacteria leading to reduced bacterial proliferation; however, most pathogenic bacteria can tolerate higher temperatures. CpxAR is a two-component regulation system, ubiquitous among Gram-negative bacteria, which senses and responds to envelope alterations that are mostly associated with protein misfolding in the periplasm. more...

(Submitter supplied) Bacteria can use host hormones as environment cue to modulate their pathogenic processes, which was discovered to play essential role in disease development. Actinobacillus pleuropneumoniae is one of the most important porcine respiratory pathogens causing great economic losses in the pig industry worldwide. Stress factors were found to contribute to the outcome of A. pleuropneumoniae infection. To test whether A. more...

(Submitter supplied) The local transcriptional response was studied in different locations of lungs from pigs experimentally infected with the respiratory pathogen Actinobacillus pleuropneumoniae serotype 5B, using porcine cDNA microarrays. This infection gives rise to well-demarcated infection loci in the lung, characterized by necrotic and haemorrhagic lesions. Lung tissue was sampled from necrotic areas, from visually unaffected areas and from areas bordering on necrotic areas. more...
