Figure 1. The majority of P. aeruginosa keratitis clinical isolates carry a genomic copy of the cif gene.

Figure 1

PCR amplification of cif gene loci in 48 clinical isolates revealed 45 strains were cif positive. In contrast, only 4 of 10 environmental P. aeruginosa isolates were cif positive. All tested strains tested positive for 16S ribosomal subunit (rplU) control.
