Effect of the Squid Host on the Abundance and Distribution of Symbiotic Vibrio fischeri in Nature

Kyu-Ho Lee, Edward G. Ruby, Applied and Environmental Microbiology

This Applied and Environmental Microbiology scholarly article provides evidence for the first recognized instance of the abundance and distribution of a marine bacterium (Vibrio fischeri) being driven primarily by its symbiotic association with an animal host (squid, Euprymna scolopes). The article reports that the typical number of Vibrio fischeri, both in the water column and in the sediments around squid Euprymna scolopes habitats, was as much as 24 to 30 times that in similar locations where squids were not observed. A link to the full-text PDF version is provided.
