Revised description and classification of atypical isolates of Pasteurella multocida from bovine lungs based on genotypic characterization to include variants previously classified as biovar 2 of Pasteurella canis and Pasteurella avium

Abstract: Strains deviating in key phenotypic characters, mainly isolated from cases of bovine pneumonia in five European countries, were genotyped in order to examine their genotypic relationship with Pasteurella multocida. Twenty-two strains of Pasteurella avium biovar 2, including variants in indole, xylose and mannitol, 18 strains of Pasteurella canis biovar 2 and variants of this taxon, five strains of P. multocida subsp. septica showing variations in indole and ornithine decarboxylase, nine strains of P. multocida… Show more

“…In our study, a phenotypic diversity concerning ornithine decarboxylase, indole, and fermentation of mannitol and sucrose has been obtained (Table 1), all being characters that have been considered as essential for the identification of P. multocida at the species level (Larivière et al, 1992). However, two recent studies have demonstrated that several isolates from diverse origins that had been regarded atypical for these four phenotypic characters, they were all ascribed genetically to P. multocida by 16S rRNA gene sequencing and DNA-DNA hybridization (Christensen et al, 2004(Christensen et al, , 2005.…”

“…Significant variations in phenotypic properties of Pasteurella multocida have been reported by several authors (Heddleston, 1976;Christensen et al ., 2004). In addition, DNA Á/DNA hybridization studies of P. multocida have shown the existence of three clusters, allowing separation at the species level.…”

“…septica distantly related to these taxa (Blackall et al ., 1998;Boerlin et al ., 2000;Petersen et al ., 2001a). Investigation of the species has shown that a formal reclassification is not possible (Christensen et al ., 2004). Correct identification depends on phenotypic and genotypic methods, in addition to consideration of the source of the isolate (Christensen et al ., 2005).…”

“…canis biovar 2 and P. avium biovar 2 were reclassified as P. multocida (Christensen et al, 2004). Therefore, the cross reactions reported by Townsend et al (1998) and Miflin and Blackall (2001) merely reflect the relatedness of these organisms and do not detract from the specificity of these assays.…”
