Abstract

The pathogens associated with diarrhoea in small ruminants include Escherichia coli, Rotavirus, PPR virus and Salmonella spp. either singly or in combination. Many researchers have worked on E. coli strains of goats almost in all agro-climatic zones of India but most of the studies were limited to only small study areas and no study has been conducted on E. coli prevalence in goats in Eastern Plain Zone of Uttar Pradesh.

The study was conducted in eight district of Eastern Plain zone of Uttar Pradesh including goat farm of ANDUAT, Kumarganj, Ayodhya which comes under Agro-climatic zone IV (Middle Gangetic Plain region). Faecal samples were collected for one year (September, 2021 to August, 2022) from dead goats having history of diarrhoea.

The overall prevalence of E. coli isolates on PCR analysis was 52.27%. The prevalence was highest in Varanasi district as 63.63% (7/11) while lowest was reported in Ghazipur district as 36.36% (4/11). The occurrence of E. coli isolates was higher in Age Group I (79.31%) followed by Age Group II (41.17%) and Age Group III (36.00%). The E. coli isolates revealed higher positivity in female (57.69%) than male (44.44%). The occurrence of E. coli isolates was highest in summer (75.86%) followed by rainy (42.42%) and lowest in winter (38.46%) season. The obtained PCR amplicons on sequencing was identified as Escherichia coli strain U 5/41 16S ribosomal RNA as it showed highest similarity of 98.96 % with accession no. NR_024570.1
