Detection of virulence factor (VF)-encoding genes (asa1, gelE, cylA, esp and hyl) and production of hemolysin (hlyB), gelatinase and aggregation substance among E. faecalis strains.

In vivo kinetics of killing of C. elegans infected by E. coli, E. faecalis and S. mitis strains.
A. Comparison of LT100 between the different strains tested alone. B. Comparison of LT100 between E. faecalis strains tested alone. C. Comparison of LT100 with strains tested alone or in association. NEF26 was representative of the different E. faecalis strains. D. Comparison of LT100 between E. coli NECS19923 strain and the different E. faecalis strains tested in association. The results are representative of at least four independent trials for each group of strains. NS: non significant.
Figure 2.
Correlation between virulence of E. faecalis strains alone (expressed by LT50s in days) and in combination with E. coli strains.
The linear regression model confirmed a linear relation. Dot corresponds to E. faecalis strains associated with NECS23048; cross corresponds to E. faecalis strains associated with NECS19923. The line and the dotted line established the linear regression of NECS23048 and NECS19923, respectively.
