"Bdellovibrio bacteriovorus
is a small, motile,
deltaproteobacterium that is a predatory invader of other gram-negative bacteria. It occupies an intraperiplasmic niche and kills, digests,
and lyses its host, the prey cell. The predatory (host-dependent, or HD) process is summarized in
Figure 1. Although there is a rare axenic host-independent (HI) growth phase
that has been produced in laboratory conditions, the rapid replication of small, motile
Bdellovibrio
cells usually occurs in 2–3 hours
by invasion (Figure 2a) and digestion of prey
and the ultimate replication (Figure 2b) and
release of more rapidly swimming
Bdellovibrio
progeny (Figure 1)." Note-duration of =4 hours given in Madigan, Michael T. (2009). Brock Biology of Microorganisms: Twelth Edition. Pearson Education p.430 caption of fig 15.33 "...Once inside [prey cell's periplasmic space], Bdellovibrio elongates and within 4 h progeny cells are released." |
