Abstract
Draft genomes of five Campylobacter isolates recovered from New Zealand brushtail possums are described. Genome sizes ranged from 1.591 Mbp to 1.594 Mbp, with G+C contents of 29.9% to 29.95%. Comparison to Australian Campylobacter 16S rRNA gene sequences suggests that the species may be common to possums.
Highlights
In the 1850s [1], the Australian brushtail possum (Trichosurus vulpecula; Maori, paihamu) was first introduced to New Zealand, where it rapidly became a significant invasive pest [1]
The 16S rRNA sequences from all isolates were identical and showed the closest BLAST similarity to Campylobacter isolate BTP1Tcr (GenBank accession number AY554142), with a pairwise sequence identity of 99.6% over 1,427 bp. This sequence was obtained from a study of Australian brushtail possums [2], which identified both Helicobacter and Campylobacter carriage
Comparison with representative 16S rRNA sequences from all other Campylobacter species showed that the closest similarity was to Campylobacter helveticus (98.7% identity, NCBI assembly accession numbers GCF_002080395 and GCF_900176295), with similar observed levels of identity with Campylobacter upsaliensis (98% to 98.4% identity, GCA_000167395, GCA_000185345, and GCA_000620965) and Campylobacter avium (98.2% identity, GCA_002238335 and GCA_002245935)
Summary
In the 1850s [1], the Australian brushtail possum (Trichosurus vulpecula; Maori, paihamu) was first introduced to New Zealand, where it rapidly became a significant invasive pest [1]. Genomes ranged in size from 1,591,228 bp to 1,594,282 bp with between 1,659 and 1,671 predicted coding sequences. The GϩC contents were between 29.9% and 29.95%.
