(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) 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) 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) 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...

(Submitter supplied) Bacteria can actively respond to host stress hormones (catecholamines), thereby regulate their growth, metabolism, virulence and other behaviors. This phenomenon provides new explanations of the fact that stress can influence the occurrence and development of infectious disease. Actinobacillus pleuropneumoniae is an important swine respiratory pathogen which has caused great economic losses worldwide. more...

(Submitter supplied) d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. more...
