Figure Lengend Snippet: Mixed infection (competition assay) by w.t. E. faecalis OG1RF and nonpiliated TX5475 in the kidneys and urinary bladder of mice (n=16). Data are expressed as log10CFU of w.t. E. faecalis OG1RF or TX5475. The log10CFU/gm from both kidneys were combined and averaged. Solid diamonds and triangles represent w.t. E. faecalis OG1RF and TX5475, respectively, from kidney homogenates and empty diamonds and triangles represent w.t. E. faecalis OG1RF and TX5475, respectively, from urinary bladder homogenates. Horizontal bars represent geometric mean titer. Mean fold difference in CFU are given. Log10 CFU were compared for statistical significance using a paired t test.

Article Snippet: Bacterial strains and growth conditions Bacteria used in the study include wild type OG1RF (resistant to rifampicin 100 μg/ml, fusidic acid 25 μg/ml) (ATCC 47077), a well-known plasmid-free isolate used in many laboratories [ 13 ]; OG1RF is a medium biofilm producer [ 7 ] and has been shown to be pathogenic in various animal models [ 12 , 14 - 17 ].

Techniques: Infection, Competitive Binding Assay

Figure Lengend Snippet: Monoinfection (106, 105, 104, and 103 inocula) using w.t. E. faecalis OG1RF or nonpiliated TX5475 in the kidneys of mice (n=10). Data are expressed as log10CFU/gm of w.t. E. faecalis OG1RF or TX5475 recovered from kidney homogenates 48 hrs after transurethral challenge. The log10CFU from both kidneys were combined and averaged. Solid and empty triangles represent w.t. E. faecalis OG1RF and TX5475, respectively. Horizontal bars represent geometric mean titer. Mean difference in CFU is given as log10 ± standard deviation (SD) for the respective inocula. TX5475 CFUs (recovered from kidneys) were significantly reduced versus OG1RF with all four inocula using unpaired t test.
