title: 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.
