(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) Actinobacillus pleuropneumoniae, the causative agent of porcine pleuropneumonia, is a highly contagious respiratory pathogen that causes severe losses to the swine industry worldwide. Current commercially-available vaccines are of limited value because they do not induce cross-serovar immunity and do not prevent development of the carrier state. Microarray-based comparative genomic hybridizations (M-CGH) were used to estimate whole genomic diversity of representative Actinobacillus pleuropneumoniae strains. 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.

(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) 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) 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...
