  Lambda phage - Wikipedia, the free encyclopedia
Enterobacteria phage λ (lambda phage) is a temperate phage that lives in E.
When all resources of the host are depleted from building new phages, the cell is lysed (the cell membrane is broken down), and the new phages are released.
The lambda phage will remain in the lysogenic state if cI proteins predominate, but will be transformed into the lytic cycle if cro proteins predominate.

 Phage Therapy as Antibiotics   (Site not responding. Last check: 2007-10-20)
Phage therapy and sanitation measures were the primary tools in his arsenal to deal with major outbreaks of infectious disease throughout the Middle East and India.
Phage therapy was tried extensively and many successes were reported for a variety of diseases, including dysentery, typhoid and paratyphoid fevers, cholera, and pyogenic (pus-producing) and urinary-tract infections.
However, it was clear that the phages readily got into the body from the digestive tract and multiplied internally wherever appropriate bacteria were present, as measured by their presence in blood and urine as well as by therapeutic effects (Weber-Dabrowska et al, 1987).

 Bacterial Cell Entry
Phage T4 Enterobacteria phage T4, genus "T4-like Viruses", family Myoviridae, or viruses with 34-170 kbp dsDNA genomes, isometric heads and contractile tails - infects the gram-negative bacterium E coli.
- Enterobacteria phage λ, genus "λ-like Viruses", family Siphoviridae, a tailed phage with an isometric head and a 49 kbp dsDNA genome - attaches to the maltose receptor on the surface of the E coli cell.
Although the tail is non-contractile, a DNA injection mechanism similar to that of T-even phages allows entry of DNA into the cell, leaving the capsid behind.
