Comments P.1845 right column bottom paragraph: "V. fischeri is the monospecific symbiont of the E. scolopes light-emitting organ. When first hatched, juvenile E. scolopes are aposymbiotic (i.e. they have no bacterial symbionts), and each generation must obtain their symbiotic bacteria from the surrounding seawater. Colonization of the squid light organ is both rapid and extremely specific, allowing V. fischeri to transition from being a minority member of the bacterioplankton (estimated at 0.01–0.15% of the ambient seawater bacteria) to being the sole resident of the host's light organ (primary source). This transition from the seawater to the interior of this organ requires passage through several distinct microenvironments within the host's tissues (Nyholm and McFall-Ngai, 2004)."
