Identification of a Bdellovibrio bacteriovorus genetic locus, hit, associated with the host-independent phenotype.

Abstract excerpt

Bdellovibrios invade and grow within the periplasmic space of suitable gram-negative bacteria. Wild-type bdellovibrios are obligately dependent on host cells for growth, but spontaneous host-independent (H-I) mutants that grow axenically on standard rich culture media can be isolated. Such mutants generally retain the ability to grow intraperiplasmically, although the plaques that they produce on lawns of host...
