Serological characterisation of Actinobacillus pleuropneumoniae
In the most recent study on the serological characterisation of Australian isolates of A pleuropneumoniae, a large percentage of isolates either gave cross-reactions with serovars 3 and 6 (47/256 isolates) or no reaction at all (91/256 isolates).11 This study was performed using slide agglutination and GD, techniques which had performed effectively in the past.5 The high incidence of isolates t...
متن کاملIndirect transmission of Actinobacillus pleuropneumoniae
orcine pleuropneumonia is caused by Actinobacillus pleuropneumoniae. This organism is thought to be transmitted mainly through direct contact, usually after asymptomatic carrier pigs are introduced into a herd. The possibility of indirect transmission has only occasionally been raised.1,2 Nicolet reported that the source of infection in Swiss specific-pathogen-free (SPF) herds was often unknown...
متن کاملActinobacillus pleuropneumoniae transferrin receptor genes
Indianapolis, IN, USA 2 Lilly Research Laboratories, The tbpA and *pi? genes encoding the transferrin receptor proteins T b p l and Tbp2 from a serotype 7 strain of Actinobacillus pleuropneumoniae were cloned, sequenced, and expressed in Escherichia coli. The tbpB gene was preceded by putative promoter and regulatory sequences and was separated from the downstream tbpA gene by a 13 bp intercist...
متن کاملActinobacillus pleuropneumoniae disease and serology
Actinobacillus pleuropneumoniae is a primary bacterial pathogen causing swine respiratory disease and has been described in most major swine-producing regions of the world. Preliminary diagnosis of A. pleuropneumoniae is based on clinical signs and gross pneumonic lesions. Isolating and identifying the causative bacteria confirms the diagnosis. Twelve serotypes of A. pleuropneumoniae and a numb...
متن کاملActinobacillus pleuropneumoniae for Use in Live Vaccines
Clonal, noniridescent mutants ofActinobaciUlus pleuropneumoniae serotypes 1 and 5 were isolated following chemical mutagenesis with ethyl methanesulfonate. The absence of any detectable capsule was confirmed by inhibition radioimmunoassay. There were no differences between the parent and mutant strains in lipopolysaccharide or protein electrophoretic profiles or in hemolytic activity. There was...
