Identification of Three Novel PmGRI1 Genomic Resistance Islands and One Multidrug Resistant Hybrid Structure of Tn7-like Transposon and PmGRI1 in Proteus mirabilis.

ABSTRACT: The widespread use of antibiotics in large-scale livestock production has led to serious antibiotic resistance. Proteus mirabilis is an important pathogenic bacterium on large-scale farms. Chromosomally localized mobilizable genetic elements (genomic islands) and mobile genetic elements (Tn7-like transposons) play an important role in the acquisition and transmission of resistance genes by P. mirabilis. To study the prevalence and resistance characteristics of antibiotic-resistant genomic islands in P. mirabilis of animal origin in China, we performed whole genome sequencing of P. mirabilis isolated from large-scale pig and chicken farms. Three new variants of PmGRI1 (HN31, YN8, and YN9), and a hybrid structure (HN2p) formed by the multidrug-resistant Tn<
