Abstract
The prevalence of integrons in five enterobacterial species was analyzed in 900 blood culture isolates from 1993, 1996, and 1999. Remarkably, the prev alence increased from 4.7% in 1993 to 9.7% in 1996 and finally to 17.4% in 1999 (P < 0.01). Within 7 years the combined percentage of P1 strong promot ers and PI weak plus P2 active promoters with high transcription efficacies has increased from 23.1 to 33.3 and finally 60% (P < 0.05).
