Table 3 Frequency of reversion to VAN-resistant phenotype

From: Dissemination and genetic analysis of the stealthy vanB gene clusters of Enterococcus faecium clinical isolates in Japan

Parent strain The frequency of reversiona
M1 (4.2 ± 2.0) × 10–7
Y7 (1.7 ± 1.2) × 10−6
M1TCb (2.4 ± 0.5) × 10−7
Y7TCb (3.5 ± 1.0) × 10–7
  1. aFrequency was estimated from the colony-forming unit (CFU) ratio of resistant strains to total strains. bCorresponding transconjugants of M1 or Y7 strain
