ACTINOBACILLUS-MINOR SP-NOV, ACTINOBACILLUS-PORCINUS SP-NOV, AND ACTINOBACILLUS-INDOLICUS SP-NOV, 3 NEW V FACTOR-DEPENDENT SPECIES FROM THERESPIRATORY-TRACT OF PIGS

The results of DNA-DNA relatedness experiments and comparisons of sequ ences of genes coding for 16S rRNA were used to determine the genetic relationships of selected V factor-dependent species belonging to the family Pasteurellaceae and obtained from the porcine respiratory tract , These results showed that the Minor group acid taxa C, D plus E, and F are distinct phylogenetic groups that are separate from each other and from other members of the family Pasteurellaceae, On the basis of these results, three new species, corresponding to the Minor group, ta xa D plus E, and taxon F, are proposed; the names of these new species are Actinobacillus minor (type strain, NM305), Actinobacillus porcinu s (type strain, NM319), and Actinobacillus indolicus (type strain, 46K C2), respectively.
