All the 35 isolates had been serogrouped from National Salmonella and Escherichia coli centre, Kasauli, H.P. (India). The isolates belonged to O17, O18, O20, O111, O118, O120, O121, O128 and Untypable serogroups and most prevalent serogroups being O18 and O121 with 20%. In conclusion, this study supplemented the information about prevalence of different serotypes of E. coli in Bikaner. In the present study O118, O120, O121 and O128 serogroups were identified which belongs to STEC pathotypes which have public health significations.
• Most prevalent serogroups was being O18 and O121.
• Serogroups O118, O120, O121 and O128 were identified which have public health significations.
