(Request a copy)We report on the re-examination of nine Australian isolates of Actinobacillus pleuropneumoniae that have been previously assigned to serovar 12. In the ring precipitation test, none of the nine isolates reacted with antisera to serovars 1-14 of A. pleuropneumoniae. Antiserum prepared against one of the Australian isolates gave no reaction with any of the 14 recognised serovar reference strains, except serovar 7. This reaction of the HS143 antiserum with serovar 7 antigen could be removed by adsorption with serovar 7 antigen. The adsorbed antiserum remained reactive with HS143 and the other eight Australian isolates. The nine Australian isolates were all shown to express ApxII and ApxIII, found in serovars 2, 4, 6 and 8, as well as the 42kDa outer membrane protein found in all serovars of A. pleuropneumoniae. The nine Australian isolates were found to possess the following toxin associated genes apxIBD, apxIICA, apxIIICA, apxIIIBD and apxIVA. The toxin gene profile of the Australian isolates is typical of A. pleuropneumoniae serovars 2, 4, 6 and 8. On the basis of the serological characterisation results and the toxin gene profiles, we propose that these isolates represent a new serovar of A. pleuropneumoniae--serovar 15--with HS143 being the reference strain for the new serovar.
