Anti-microbial Resistance Profile of E. coli Isolates from Free-Range Turkey: Figure 4
shows that free-range turkeys yielded E. coli organism that were highly resistant to
co-trimoxazole, nalidixic acid and ampicillin (100%), and nitrofurantoin and
chloramphenicol (66.7%). These organisms however recorded 0% resistance to
gentamicin and ciprofloxacin.

Cf, cefuroxime; Nb, norfloxacin; Co, cotrimoxazole; Gn, gentamicin; Te, tetracycline; Cp,
ciprofloxacin; Na, nalidixic acid; Ch, chloramphenicol; Am, ampicillin.
Anti-microbial Resistance Profile of E. coli Isolates from Broiler Roosters: E. coli
isolates from broiler roosters (Figure 5) recorded 100% resistance against
cotrimoxazole and ampicillin, 85.7% to nalidixic acid and chloramphenicol and 78.6%
to nitrofurantoin. Furthermore, gentamicin, ciprofloxacin and cefuroxime recorded 0,
7.1 and 7.1% resistance respectively.
