| final classification of bisgaard taxon 9 as actinobacillus arthritidis sp. nov. and recognition of a novel genomospecies for equine strains of actinobacillus lignieresii. | phenotypic characterization of bacteria from diseased and healthy horses identified 18 isolates as bisgaard taxon 9 and 11 isolates as actinobacillus lignieresii. all strains of taxon 9 were alpha-galactosidase- and raffinose-positive and showed variable fermentation of (+)l-arabinose and (-)d-sorbitol. strains of a. lignieresii were negative for these characteristics, with the exception of raffinose. two strains from the (-)d-sorbitol-negative group of taxon 9 showed a 16s rrna similarity of 99 ... | 2002 | 12148635 |
