Q

Cui se datoreaza capacitatea de supravietuire a Enterococus Faecalis?

A
  1. Abilitatii de a coloniza peretii c.r. si de a se organiza in biofilm dens
  2. patrunde (dim redusa) in prof tubulilor dentinari , evadand actiunea instr endo, a irigantilor, a medicatiei
  3. rezistenta fata de Ca(OH)2
  4. poate trai independent de nutrientii altor bacterii din lanturile nutritive
  5. se adapteaza conditiilor nefavorabile prin reglare expresie genetica
