A. Marchese et al., Heterogeneous vancomycin resistance in methicillin-resistant Staphylococcus aureus strains isolated in a large Italian hospital, J CLIN MICR, 38(2), 2000, pp. 866-869
Of 179 methicillin-resistant Staphylococcus aureus strains isolated from 19
97 to 1998, two strains (1.1%) gave subclones for which the vancomycin MICs
were 8 mg/liter. Pulsed-field gel electrophoresis showed identical restric
tion patterns for both isolates, suggesting transfer of a single clone betw
een two different patients.
