Effects of Actinobacillus pleuropneumoniae hemolysin on porcine neutrophil function.
In an attempt to gain insight into the events that take place during Actinobacillus pleuropneumoniae infection, the present study was designed to ascertain the effects of bacterial toxicity on porcine neutrophil functions and viability. Incubation of phagocytes (2 x 10(6)) with opsonized A. pleuropneumoniae 4074 (2 x 10(7) CFU) resulted in phagocytic uptake of less than or equal to 4%. At the s...
متن کاملPrevalence of seroreactors to the 104-kilodalton hemolysin of Actinobacillus pleuropneumoniae in swine herds.
A rabbit homologous polyclonal antiserum to the 104-kilodalton hemolysin of Actinobacillus pleuropneumoniae serotype 1 strain CM-5 was specifically produced and used in an antigen capture enzyme-linked immunosorbent assay (ELISA) to detect swine serum antibodies to this potentially important virulence factor. Sera from pigs experimentally infected with the most common disease-producing serotype...
متن کاملSerological 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...
