• We describe here isolation of genetically atypical serotype 6 Actinobacillus pleuropneumoniae in Japan indistinguishable by the multiplex PCR that can discriminate between immunologically cross-reactive serotypes 3, 6 and 8. The nucleotide sequence analysis of capsular export and biosynthesis genes revealed that the atypical isolates have capsular polysaccharide export and synthesis gene sequences which are distinct from that of serotype 6 reference strain. The atypical strains have an identical sequence with both serotype 3 and 6-specific primers, which causing cross-reactions in the multiplex PCR.
