- Fig. 1.
PFGE of total XbaI-restricted DNA from ESBL-producing E. aerogenes strains. M, lambda ladder. ESBL-producing E. aerogenes strains were isolated from a patient's postsurgical wound (lanes 1 and 2), feces (lanes 3 and 4), and urine (lane 5). ESBL-producing E. aerogenes strains were isolated from three other patients hospitalized in three different ICUs in our hospital (lanes 6 to 8). The size of the ladder is indicated in kilobases.

PFGE of total SpeI-restricted DNA fromP. aeruginosa strains. M, lambda ladder. P. aeruginosa strains were isolated from the same patient's wound (lane 1), urine (lanes 4 and 6, ESBL-producing P. aeruginosa; lane 7, β-lactam susceptible P. aeruginosa), and sputum (lane 2, 3, and 5). The sizes are indicated in kilobases.
