Susceptibility of Arcobacter butzleri to heavy metals

Abstract

The susceptibility of 50 strains of Arcobacter butzleri isolated from chicken liver [12], mussels [18], river water [6] and bovine [5], duck [2] and pelicans [7] feces to mercury (Hg), chromium (Cr), silver (Ag), nickel (Ni), cobalt (Co), iron (Fe), manganese (Mn), molybdenum (Mo) and lead (Pb) was determined.All the strains were resistant to Mo, Mn, Ni, Co, Pb and Fe and susceptible to Hg, Ag and Cr. MIC values showed high variability, indicating a non homogeneous behavior among the strains.
