dc.description.abstractEscherichia coli has been recognized as a pathogen of concern in the antimicrobial resistance (AMR) perspective. Globally initiatives were taken to control AMR. Bacteriophages are recognized as promising alternative to antibiotics. Harnessing broad-spectrum bacteriophages for augmenting phage repositories is being prioritized across continents for future health care needs. In this context, a study was conducted to isolate coliphages against a collection of AMR E. coli isolated from diverse aquatic niche. Thirty pooled water samples (5 each from rivers, aquaculture ponds, lake, sewage treatment plant, domestic waste and canals) were analysed, and fifty-four lytic coliphages were isolated against the wide range of E. coli host strains. Broad host-spectrum phages were isolated predominantly from sewage water samples. Enriched phages were quantified, and the concentrations ranged from 106 to 107 PFU/mL. Ten phages, viz. ФEC-S-18, ФEC-S-21, ФEC-S-22, ФEC-S-23, ФEC-S-24, ФEC-S-25, ФEC-S-28, ФEC-S-30, ФEC-S-39 and ФEC-S-49, exhibited lytic activity against more than ten AMR strains of E. coli. PCR analysis of the 54 phages using the major capsid protein (MCP) specific primers coupled with gene sequence analysis identified two phages related to Berlinvirus and 35 phages to Kayfunavirus of Autographiviridae. However, the remaining 17 phages did not show amplification using the MCP primers. The study has demonstrated that aquatic environment harboured phages with broad host spectrum that can potentially be used as agents for biological control of E. coli for infection control and food safety.
