In order to facilitate the process, they have constructed cDNA libraries at these time points of both aposymbiotic and symbiont juveniles (Visick, KL and MJ McFall-Ngai). "Control of bioluminescence in Vibrio fischeri by the luxO signal response regulator." Euprymna scolopes (Figure 1) is a small sepiolid squid, or bobtail squid, occurring in the marine V. fischeri luminescence is the result of the oxidation of Hawaiian bobtail squid Margaret McFall-Ngai What is a bobtail squid? Vibrio fischeri is a bioluminescent bacterium that colonizes the Hawaiian bobtail squid, Euprymna scolopes.
The protein LuxI synthesizes AHL. The family Vibrionaceae are motile, Gram-negative rods that are natural inhabitants of seawater but can be found in fresh water. Yip, E. S., K. Geszvain, C. R. DeLoney-Marino, and K. L. Visick. But the Vibrio fischeri don't stay in the squid continuously. Older browsers that do not support HTML5 and the H.264 video codec will still use a Flash-based video player. Springer-Verlag, Germany. And symptoms associated with septicemia include fever, hypothermia, hypotension, acute respiratory distress syndrome, and multiple organ dysfunction (Hoi Ho, et al.).

Luminescent bacteria are found in free-living, symbiotic, saprophytic or parasitic relationships.
Every day, in response to the light cue of dawn, the squid vents 90 percent of the bacteria back into the seawater. Biology (BIMM) 101 Lab Manual. The method outlines the procedure by which the Hawaiian bobtail squid, Euprymna scolopes and its bacterial symbiont, Vibrio fischeri, are raised separately and then introduced to allow for specific colonization of the squid light organ by the bacteria. After stimulation, The LuxR AHL complex bind to the lux box causing the activation of luminescence genes.

They are now subtracting these libraries to determine the gene expression brought about by interaction with Davis, Aubrey. (2006). Microbiol. 62:1586-1600. Epub 2004 Jul 15. J Bacteriol. Hoi Ho, Thong Huy Do, Tony Tran Ho, Derek Lee. Autoinducers modify gene expression after a sudden change in the cell population density. "The symbiosis regulator RscS controls the syp gene locus, biofilm formation and symbiotic aggregation by Vibrio fischeri." 2004 Dec 12;20(18):3682-6. The reaction that occurs in Quorum sensing bacterias help the regulation of the gene expression of Vibrio Fisheri in response to changes in cell density. Patient symptoms associated with gastroenteritis include diarrhea, abdominal cramps, nausea, vomiting, headaches, bloody stools, etc. p. 277-290.
