coli O157:H7 is an emerging food borne pathogen having zoonotic importance. Though the primary reservoir of this serotype is cattle; Sheep and goats are also considered to be the main reservoir for E. coli O157:H7. In the present study, faecal samples were collected from sheep (n=517) and goats (n=450) in different farms across Hyderabad-Karnataka region during June 2016 to August 2017 were analysed. The samples were processed and analysed for the isolation, identification and confirmation of E. coli O157:H7 by cultural, biochemical characterization and latex agglutination test. The prevalence is more in male (4.14 % in sheep and 2.94 % in goats) than female (3.26 % in sheep and 2.84 % in goats), also in yearlings (6.25 % in sheep and 5.08 % in goats) than lambs or kids (3.35 % in sheep and 4.22 % in goats) and adult sheep or goats (2.02 % in sheep and 1.56 % in goats). The prevalence of E. coli O157:H7 varied between seasons with the highest prevalence occurring in summer (3.70 % in sheep and 3.70 % in goats) followed by monsoon (3.30 % in sheep and 1.81 % in goats) and winter seasons (2.79 % in sheep and 2.30 % in goats). Understanding above factors will contribute to shedding of E. coli O157:H7 in small ruminants which help in development of control strategies to reduce pre-harvest incidence of food borne pathogen in humans.
