Interpretive Summary: Pseudomonas aeruginosa is an opportunistic pathogen and it can cause acute and chronic mastitis in cattle. Pseudomonas species are environmental pathogens and can be found in humid areas such as soiled beddings, manure, contaminated water, and milking parlors. Here in this study, whole genome of a multidrug resistant P. aeruginosa strain, which was isolated from a naturally occurring case of chronic mastitis, was sequenced. Presence of multiple antibiotic resistance genes in its' genome explained the lack of initial response to antibiotic treatment and should assist us to develop future treatment plans.

Technical Abstract: We report the complete genome sequence of a multidrug-resistant Pseudomonas aeruginosa strain isolated from a Holstein cow with chronic mastitis. The assembled genome contained 108 contigs with an N50 of 130,886 bp, 66.03%, GC content, 6,214 protein-coding genes, 64 RNA genes, 88 pseudogenes, and six antibiotic resistant genes.
