Plasmid distribution in Escherichia coli urinary isolates with special reference to aerobactin and colicin production
Abstract
Plasmids were detected in 31 out of 35 strains of Escherichia coli isolated from unclassified cases of urinary tract infection at a median value of 1.88 plasmid bands per isolate. The isolates showed an association of aerobactin and colicin production with the distribution of plasmid bands having a median value of 2.33 and 1.72 (plasmid bands per isolate) in aerobactin-positive and aerobactin-negative strains respectively. For colicin producers, the median plasmid bands per isolate was 3.66 compared to 1.80 for colicin-negative strains.
