<unk> e have the ability to establish long-term associations with host<unk> ells. When an infected host<unk> ell is starved for various nutrients such as amino acids (for example, tryptophan), iron, or vitamins, this has a negative<unk> onsequence for<unk> e since the organism is dependent on the host<unk> ell for these nutrients. Long-term<unk> ohort studies indicate that approximately 50% of those infected<unk> lear within a year, 80% within two years, and 90% within three years. The starved<unk> e enter a persistent growth state wherein they stop<unk> ell division and become morphologically aberrant by increasing in size. Persistent organisms remain viable as they are<unk> apable of returning to a normal growth state once<unk> onditions in the host<unk> ell improve. There is debate as to whether persistence has relevance. Some believe that persistent<unk> e are the<unk> ause of<unk> hronic<unk> l diseases. Some antibiotics such as β-lactams have been found to induce a persistent-like growth state.
