ERIC-PCR genotyping of Haemophilus parasuis isolates from Brazilian pigs

Among 63 Haemophilus parasuis isolates from 17 Brazilian pig herds, 33 genotypes were identified by enterobacterial repetitive intergenic consensus (ERIC)-PCR, with a diversity index of 0.96. Eight serovars were detected, with serovar 4 (15.9%) being most frequent; 60.3% of isolates were non-typeabl...

Zusammenfassung:	Among 63 Haemophilus parasuis isolates from 17 Brazilian pig herds, 33 genotypes were identified by enterobacterial repetitive intergenic consensus (ERIC)-PCR, with a diversity index of 0.96. Eight serovars were detected, with serovar 4 (15.9%) being most frequent; 60.3% of isolates were non-typeable. There was no strong association between site of isolation and genotype or serovar.
