A novel 61,578-bp genomic island named Proteus genomic island 2 (PGI2) was characterized in Proteus mirabilis of swine origin in China. The 23.85-kb backbone of PGI2 is related to those of Salmonella genomic island 1 and Acinetobacter genomic island 1. The multidrug resistance (MDR) region of PGI2 is a complex class 1 integron containing 14 different resistance genes. PGI2 was conjugally mobilized in trans to Escherichia coli in the presence of a conjugative IncC helper plasmid. Copyright © 2018 American Society for Microbiology.
