of the animal. The bacterium has been successfully inoculated into other 

 species of amphipods and isopods, which subsequently become luminous. 

 Luminescent bacteria have also been recovered from the gut of non- 

 luminous amphipods, and Harvey suggests that infection of the body tissues 

 occurs by this route under suitable conditions. Other marine invertebrates 

 can be readily infected with luminescent bacteria and become luminous; 

 for example, Palaemon, Sepia, Ciona and many teleosts. If the infection is 

 not fatal the animal recovers in the course of a few weeks and the light 

 gradually disappears (12, 42).
