Screening of Actinobacillus pleuropneumoniae LuxS Inhibitors
Current Microbiology, 2013LuxS, a conserved bacterial enzyme involved in the activated methyl cycle, catalyzes S-ribosylhomocysteine (SRH) into homocysteine and AI-2 (the inter-species quorum-sensing signal molecule). This enzyme has been reported to be essential for the survival of Actinobacillus pleuropneumoniae in its natural host.

Design and analysis of an Actinobacillus pleuropneumoniae transmission experiment
Preventive Veterinary Medicine, 2003This paper describes a methodology to quantify the transmission of Actinobacillus (A.) pleuropneumoniae from subclinically infected carrier pigs to susceptible contact pigs, and to test the effect of possible interventions on the transmission. The methodology includes the design of a transmission experiment, and a method with which A.

Virulence in Actinobacillus pleuropneumoniae and RTX toxins
Trends in Microbiology, 1995RTX toxins are pore-forming, cytolytic protein toxins that occur widely among pathogenic Gram-negative bacteria. RTX toxins appear to play a direct role in the virulence of Actinobacillus pleuropneumoniae, the etiological agent of porcine pleuropneumonia.

Exotoxins of Actinobacillus Pleuropneumoniae
1995Actinobacillus pleuropneumoniae (previously Haemophilus pleuropneumoniae) is the etiological agent of swine pleuropneumonia, a severe, contagious disease of swine causing important economic losses in industrialized swine production worldwide. The disease is either acute and often fatal or chronic localized and necrotizing.

Effects of fisetin on virulence of Actinobacillus Pleuropneumoniae
Microbial PathogenesisPorcine infectious pleuropneumonia (PCP), caused by Actinobacillus pleuropneumoniae (APP), is a highly infectious respiratory disease of pigs, resulting in significant economic losses to the industry. Apx toxins are cytolytic virulence factors produced by APP.

A riboflavin auxotroph of Actinobacillus pleuropneumoniae is attenuated in swine
Infection and Immunity, 1996Actinobacillus pleuropneumoniae is the etiological agent of a highly contagious and often fatal pleuropneumonia in swine. A riboflavin-requiring mutant of A. pleuropneumoniae serotype 1, designated AP233, was constructed by deleting a portion of the riboflavin biosynthetic operon (ribGBAH) and replacing it with a gene cassette encoding kanamycin ...

Characterization and immunogenicity of an apxIA mutant of Actinobacillus pleuropneumoniae
Veterinary Microbiology, 2006Actinobacillus pleuropneumoniae is the aetiological agent of porcine pleuropneumonia, a highly contagious and often fatal disease. A candidate live vaccine strain, potentially capable of cross-serovar protection, was constructed by deleting the section of the apxIA gene coding for the C-terminal segment of ApxI toxin of the A.

Characterization of tetracycline and erythromycin resistance in Actinobacillus pleuropneumoniae
Veterinary Microbiology, 1996Minimum inhibitory concentrations to tetracycline and erythromycin were determined for nineteen isolates of Actinobacillus pleuropneumoniae of Norwegian origin. The isolates were screened for rRNA methylase determinants (Erm genes) and for the tetracycline resistance Tet B determinant, using oligonucleotide probes, polymerase chain reaction and ...

Immunological properties of Actinobacillus pleuropneumoniae hemolysin I
Veterinary Microbiology, 1991The 105 kDa hemolysin I protein from Actinobacillus pleuropneumoniae serotype I type strain 4074 (HlyI) was shown by immunoblot analysis to be the predominant immunogenic protein if convalescent field sera or sera from pigs experimentally infected with A. pleuropneumoniae serotype 1 were used.
