Fig. 4.
Bacterial persistence within mouse organs. Enterococcal tissue burdens in kidneys and in livers from BALB/c mice infected intravenously with 1 × 108 cells of E. faecalis wild-type V19 and the ΔslyA mutant strain are shown. Kidney pair and liver homogenates were obtained from groups of 10 mice sacrificed and necropsied at day 7 postinfection. The results, expressed as log10 CFU per gram of tissue, represent values recorded separately for each of the 10 mice. Horizontal bars represent the geometric means. P values of less than 0.05 were considered to be significant.
