A total of 5000 faecal samples (2500 from each district) were collected from clinically suspected goats and cultured on selective media. Molecular confirmation was performed by PCR targeting the epsilon toxin (etx) gene. Antibiotic susceptibility was assessed via the Kirby-Bauer disc diffusion method.

The prevalence was 400/2500 (16%) in Peshawar and 300/2500 (12%) in Charsadda, with peak occurrences during spring and winter. Isolates showed complete resistance to gentamicin and high resistance to tetracycline and amoxicillin but were largely susceptible to teicoplanin, sulphamethoxazole and trimethoprim. Parenteral antibiotic therapy resulted in significantly higher recovery (80%) than enteral treatment (30%) (p < 0.05).
