FIG 1.
(A) Schematic representation of the class 2 integron harbored within the P. mirabalis isolates. The vertical rectangle represents the attL2 site found in the intL2 gene cassette. Each gene cassette consists of a gene, represented by an arrow, and its corresponding attC site, represented by ovals. (B) Schematic representation of the class 2 integron putative promoter sequence, transcriptional start site, core site, and blaIMP-27 start codon. (C) Schematic representation of the P. mirabilis integron 2 dfrA1 attC recombination site.
