(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) 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) 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 two-component system qseBC is a putative prokaryotic adrenergic receptor. In Aggregatibacter actinomycetemcomitans (Aa), it was shown that the qseBC responds significantly to the presence of both catecholamines and ferrous iron. In addition, growth is significantly increased in the presence of both. Therefore, we performed a custom Aa microarray in order to determine the effects of catecholamines and catecholamines and iron (CAT-Fe) on Aa.

(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...
