Proteus faecis is a gram-negative facultative anaerobic rod-shaped bacterium capable of swarming motility. It has been isolated from numerous sources such as humans, animals, and refuse and is considered potentially pathogenic towards humans. In this study, bacteria were isolated from the blowhole of a Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis; YFP) living in captivity in China. One bacterium, P. faecis porpoise, was isolated and whole genome sequencing done. Biofilm formation, motility and antimicrobial resistance were also investigated. To find putative virulence factors, the genome of P. faecis strain porpoise was compared to the genomic sequences of eight other P. faecis isolates using the Bacterial and Viral Bioinformatics Resource Center (BV-BRC) ( https://www.bv-brc.org/ ). The goal of this study was to initially characterize the pathogenicity of this bacterium isolated from a cetacean species using both pathogenomics and conventional approaches.
