  1. AA = Addis Ababa; AA/JM = Addis Ababa and Jimma; Amp = ampicillin; BD = Bahirdar; BL = Belgium; Chl = chloramphenicol; Cip = ciprofloxacin; Cro = ceftriaxone; DM = Denmark; ET = Ethiopia; EU/USA = Europe and the United States of America; HR = Harar; JM = Jimma; GD = Gondar; n = number of isolates; nr = not reported; nt = not tested; Sxt = co-trimoxazole; Ys = Year of study.
  2. aThe numbers of chloramphenicol and ampicillin resistant isolates were derived from the proportions of sensitive isolates.
  3. bThe third highest mono-drug resistant isolates number was considered as the number of MDR isolates assuming that the prevalence of MDR isolates is mainly a reflection of the highly resisted drugs.
  4. cData on amoxicillin was substituted to ampicillin assuming that the mechanism of resistance could be similar.
  5. dThe data show the proportions of drug resistant S. Concord.
  6. eThe exact origin of the adoptees was not reported.
