Figure 1. Fecal excretion of vancomycin-resistant E. faecium strains by a human subject. Log10 viable counts (CFU) of cocci per gram feces isolated on Mitis’Salivarius (MS) agar containing sodium nalidixate (20 mg/L) and vancomycin (10 mg/L) (□) or sodium nalidixate alone (▪) at days indicated after the start of the experiment. ↓ indicates the day of ingestion of a particular strain together with the number of CFUs ingested. (+) indicates isolation of the vancomycin-resistant strain by enrichment only. Isolation of vancomycin-sensitive or -resistant cocci from perianal skin swabs incubated overnight in vancomycin-sodium nalidixate broth, subcultured on MS agar (MS) or MS agar containing vancomycin (MS + VAN) respectively is indicated by a + or − at the bottom of each panel.
