Four methods, namely, biotyping, cell envelope protein electrophoresis, ribotyping, and comparison of antibiograms, were used for strain identification of Acinetobacter isolates from five outbreaks in hospitals. There was good agreement among the methods for the identification of an index strain, but biotyping and the comparison of antibiograms were the least discriminatory.
Dijkshoorn et al. (1993) studied this question.
