F. Bert et N. Lambertzechovsky, ANALYSIS OF A CASE OF RECURRENT BACTEREMIA DUE TO GROUP-A STREPTOCOCCUS-EQUISIMILIS BY PULSED-FIELD GEL-ELECTROPHORESIS, Infection, 25(4), 1997, pp. 250-251
An 86-year-old woman with a history of metastatic breast cancer develo
ped two episodes of streptococcal bacteraemia and erysipelas separated
by an interval of 3 months. The isolates belonged to Lancefield group
A, but were biochemically identified as Streptococcus equisimilis. Th
e similarity of the two isolates was established by DNA macrorestricti
on analysis and pulsed-field gel electrophoresis, indicating that the
second episode was due to relapse and not reinfection.
