“…It is actively motile and after adsorption onto the host, a specific enzyme(s) is induced in the parasite (Varon and Shilo, 1968). Maturation begins when the parasite penetrates through the outer membrane into the host periplasm where, -60 min later, synthesis of B. bacteriovorus DNA begins (Matin and Rittenberg, 1972; Rosson and Rittenberg, 1979). The parasite causes shut-off of the host macromolecular synthetic apparatus, and is able to grow on host cells killed by various agents, including antibiotics (Varon et al, 1969;Rittenberg and Shilo, 1970).…”
