Actinobacillus pleuropneumoniae is a bacterial pathogen that causes highly contagious respiratory infection in pigs and has a serious impact on the production economy and animal welfare. As clear differences in virulence between serotypes have been observed, the genetic basis should be investigated at the genomic level. Here, we present the draft genome sequences of the A. pleuropneumoniae sero...

Previously, we reported the construction and characterization of a genetically defined Actinobacillus pleuropneumoniae (A. pleuropneumoniae) apxIIC gene mutant, HB04C(-), which conferred protection to mice against infection with A. pleuropneumoniae. In this study, we further evaluated HB04C(-) for safety and its ability to elicit protective immunity in pigs. It was demonstrated that a dose of 2...

Ten transmission trials with Actinobacillus pleuropneumoniae were carried out. The observed transmission was highly variable, which was surprising since the design of the trials was very similar. We investigated whether the variable transmission could be explained by variation in infectivity of A. pleuropneumoniae infected pigs. We looked for measurable characteristics, which could be indicativ...

The objective of this study was to compare the performance of different diagnostic tests for the detection of pigs subclinically infected with Actinobacillus pleuropneumoniae. To address this question, we infected pigs with APP serotypes 1, 3, 5, 7, 10, 12, and 15 and collected weekly tonsil swabs for isolation and PCR and serum samples for serological testing. Our results showed that the Multi...

Twenty-four isolates of Actinobacillus seminis were typed by PCR ribotyping, repetitive extragenic palindromic element (REP)-based PCR, and enterobacterial repetitive intergenic consensus (ERIC)-based PCR. Five types were distinguished by REP-PCR, and nine types were distinguished by ERIC-PCR. PCR ribotyping produced the simplest pattern and could be useful for identification of A. seminis and ...

Actinobacillus pleuropneumoniae causes porcine pleuropneumoniae which is one of severe threats to the swine industry. In total, 54 strains of Actinobacillus pleuropneumoniae were isolated from 443 pigs between 2012 and 2013 in Korea. Isolates were classified into serotypes 1, 2, 5, 7, 12, and unclassified by multiplex PCR. Genotypes of isolates were divided into three groups according to the se...

Three genetically defined Actinobacillus pleuropneumoniae serotype 7 mutants with deletions in the small (tbpB), the large (tbpA), and both transferrin binding protein genes were constructed and examined in an aerosol infection model. Neither mutant caused clinical disease or could be reisolated, and no immune response could be detected 21 days after infection. This result clearly implies that ...

The present study reports the first isolation of Actinobacillus seminis from a goat in Brazil. A four-year-old Moxotó breeding goat in a flock of 70 goats and 65 sheep reared together in the county of Patos, semiarid region of Northeastern Brazil, showed clinical signs of unilateral orchitis and epididymitis. Diagnosis of A. seminis infection was confirmed by association of clinical findings, b...

Approximately 6% of 50 tested human sera possessed precipitating antibody against lipopolysaccharide from Haemophilus actinomycetemcomitans (Actinobacillus actinomycetemcomitans).

Actinobacillus actinomycetemcomitans is a gram-negative coccobacillus which is a very rare cause of bacterial endocarditis. Preexisting cardiac lesions are a main contributing factor, and antibiotic prophylaxis has long been felt necessary before dental or other manipulation to prevent endocarditis. Penicillin in combination with an aminoglycoside has been the most often used treatment regimen....
