“…No acid was produced by any strain from glycerol, meso-erythritol, adonitol, Darabitol, xylitol, L- The family Pasteurellaceae has been studied extensively by molecular methods such as DNA-DNA hybridization, rRNA-DNA hybridization and 16S rRNA gene sequence analysis in recent years (Angen et al, 1999(Angen et al, , 2003Christensen et al, 2003a;De Ley et al, 1990;Dewhirst et al, 1993;Mutters et al, 1989). These studies have clearly shown that the original three genera of Haemophilus, Actinobacillus and Pasteurella were polyphyletic and have resulted in the establishment of six new genera: Gallibacterium, Histophilus, Mannheimia, Lonepinella, Phocoenobacter and Volucribacter (Angen et al, 1999(Angen et al, , 2003Christensen et al, 2003aChristensen et al, , 2004bFoster et al, 2000;Osawa et al, 1995). The studies on these new genera, particularly Gallibacterium (Christensen et al, 2003a) and Volucribacter (Christensen et al, 2004b), have highlighted that the other members of the avian 16S rRNA cluster 18 within the Pasteurellaceae represent another group of taxa that needs reclassification.…”
