Antibiotic-resistant E. coli is a growing concern in various settings, but environmental studies are rare compared to clinical research on human and animal health. This study aimed to identify the prevalence of E. coli bacteria resistant to different antibiotics in the environment by examining E. coli resistant to cefotaxime isolated from ruminant stool, feed, and compost. The phenotyping test was conducted through antibiotic susceptibility test using Kirby-Bauer disk-diffusion method, followed by the One-Way variance (ANOVA) analysis of the antibiotic susceptibility test results. Of the 12 isolates exposed to cefotaxime, six showed resistance to this antibiotic, and all isolates, including those resistant to cefotaxime, were resistant to eight out of ten types of antibiotics. All isolates had resistance to at least two to five types of antibiotics. The phenotypic pattern between fecal isolates and non-fecal isolates did not differ significantly, except for the antibiotics amoxicillin (p≤0.05) and ampicillin (p≤0.05). The overlapping resistance patterns observed in animal feed, animal stool, and compost suggest a potential link between their microbiological compositions.
