Serological characterisation of Australian isolates of Actinobacillus pleuropneumoniae

Abstract

SUMMARY: Using hyperimmune rabbit antiserums to 8 reference serovar strains, a total of 51 Australian isolates of Aclinobacillus pleuropneumoniae were serotyped by either a rapid slide agglutination test or a gel diffusion test. The results were: serovar 1 — 24 isolates; serovar 2 — 6 isolates; serovar 3 — 5 isolates; serovar 7 — 15 isolates; nontypable — 1 isolate. The rapid slide agglutination test was suitable for screening field isolates, as 73% of those tested reacted with only 1 of the 8 antiserums and were assigned to a particular serovar of the basis of this test alone.
