(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) 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) 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) 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) 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) 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...

(Submitter supplied) To study hepatic gene expression differences, liver samples from infected pigs (n = 10) were compared with liver samples from the non-infected control group (n = 5). Ten microarrays were performed, such that 5 randomly selected cDNA samples from the infected group were labeled with Oyster 550 (Genisphere Inc., Hatfield, PA, USA) and compared directly to 5 control animals labeled with Oyster 650 (Genisphere) analysing a pair of samples (one from an infected animal and one from a randomly chosen non-infected animal) on each microarray slide. more...

(Submitter supplied) Actinobacillus pleuropneumoniae is the cause of porcine pleuropneumonia, a severe respiratory tract infection that is responsible for major economic losses to the swine industry. Many host-adapted bacterial pathogens encode systems known as phasevarions (phase-variable regulons). Phasevarions result from variable expression of cytoplasmic DNA methyltransferases. Variable expression results in genome-wide methylation differences within a bacterial population, leading to altered expression of multiple genes via epigenetic mechanisms. more...

(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...

(Submitter supplied) Peripheral blood mononuclear cells (PBMCs) were isolated from the blood of pigs at different time points (0, 24 and 120 h) post infection and their transcriptome determined by Illumina HiSeq 4000 high-throughput sequencing. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis of the DEGs revealed the close relationship between the peripheral blood and inflammatory response from the perspective of molecular function, cell composition, biological processes and signalling pathways.
