show Abstracthide AbstractIn Norway there was an outbreak of acute haemorrhagic diarrhoea syndrome in dogs in 2019. Bacterial cultivation indicated that strains from the species Providencia alcalifaciens were the likely cause of the syndrome. Here we performed shotgun sequencing and hybrid whole genome assembly using MiSeq Illumina and Oxford nanopore sequence data on P. alcalifaciens isolates. The goal of our analysis was to determine if the isolates obtained from different diseased dogs were from a common point source. These analysis were performed as part of the Norwegian Veterinary Institute in-house project SEQTECH.
