Remarks: Genetic diversity among 86 Pasteurella multocida isolates was investigated by comparative sequence analysis of a 1468 bp fragment of the 16S rRNA gene. The strains included 79 field isolates recovered from birds (poultry) (22), cattle (21), pigs (26) and sheep (10) within England and Wales, four Asian isolates associated with bovine haemorrhagic septicaemia, and the type strains of the three subspecies of P. multocida. Dulcitol and sorbitol fermentation patterns were also determined to establish correlations between subspecies status and phylogenetic relatedness. Nineteen 16S rRNA types were identified, but these were clustered into two distinct phylogenetic lineages, A and B. Sequences within lineages A and B had a mean number of nucleotide differences of 21.123.90. Isolates within lineage A were associated with birds, cattle, pigs and sheep, whereas those belonging to lineage B were recovered from birds and a cat. Eighty-seven per cent of the isolates were classified as P. multocida subsp. multocida by dulcitol and sorbitol fermentation patterns, but these have diverse 16S rRNA gene sequences that were represented in both lineages A and B. Avian P. multocida subsp. septica isolates were associated exclusively with lineage B, but bovine P. multocida subsp. septica isolates were present in lineage A. P. multocida subsp. gallicida isolates of avian, bovine and porcine origin represent a homogeneous group within lineage A, but they have the same 16S rRNA type as certain P. multocida subsp. multocida isolates. These findings provide strong support for the view that dulcitol and sorbitol fermentation patterns are inaccurate indicators of genetic relatedness among P. multocida strains. Avian capsular type B isolates and capsular type B and E isolates associated with haemorrhagic septicaemia of cattle and water buffaloes are closely related and form a distinct cluster within lineage A. The current subspecies nomenclature of P. multocida neither accurately reflects the 16S rRNA-based phylogenetic relationships among isolates nor does it adequately encompass the full range of diversity within the species. The study provides a 16S rRNA-based evolutionary framework that will form the basis of further studies into the genetic diversity of P. multocida and will also help in the reclassification of the species.

Note:

The Culture Collections hold cell cultures, bacteria, fungi and virus strains from worldwide sources. Our scientists ensure that the identification of the cultures is correct and they remain unchanged from when they are first deposited with the Collection. Nevertheless, some of the data we provide about the cultures is supplied by the person depositing the strains and, although we have multiple checking procedures in place, we cannot always verify all their data. Please note that the Culture Collections cannot be held responsible for any inaccuracies in the data provided by the depositors.

Cultures supplied by Culture Collections are to be used as controls for microbiology testing and for research purposes only. Please view the Terms & Conditions of Supply for more information.
