Abstract:
This study aimed at detecting the prevalence of antibiotic-resistant serotypes of Escherichia coli in Cochin estuary, India. E. coli
strains were isolated during the period January 2010–December 2011 from five different stations set at Cochin estuary. Water
samples from five different stations in Cochin estuary were collected on a monthly basis for a period of two years. Isolates were
serotyped, antibiogram-phenotyped for twelve antimicrobial agents, and genotyped by polymerase chain reaction for uid gene
that codes for β-D-glucuronidase. These E. coli strains from Cochin estuary were tested against twelve antibiotics to determine
the prevalence of multiple antibiotic resistance among them. The results revealed that more than 53.33% of the isolates were
multiple antibiotic resistant. Thirteen isolates showed resistance to sulphonamides and two of them contained the sul 1 gene.
Class 1 integrons were detected in two E. coli strains which were resistant to more than seven antibiotics. In the present study,
O serotyping, antibiotic sensitivity, and polymerase chain reaction were employed with the purpose of establishing the present
distribution of multiple antibiotic-resistant serotypes, associated with E. coli isolated from different parts of Cochin estuary.
