Colonization of Euprymna scolopes squid by Vibrio fischeri.
Specific bacteria are found in association with animal tissue. Such host-bacterial associations (symbioses) can be detrimental (pathogenic), have no fitness consequence (commensal), or be beneficial (mutualistic). While much attention has been given to pathogenic interactions, little is known about the processes that dictate the reproducible acquisition of beneficial/commensal bacteria from the...
متن کاملPopulation dynamics of Vibrio fischeri during infection of Euprymna scolopes.
The luminous bacterium Vibrio fischeri colonizes a specialized light-emitting organ within its squid host, Euprymna scolopes. Newly hatched juvenile squid must acquire their symbiont from ambient seawater, where the bacteria are present at low concentrations. To understand the population dynamics of V. fischeri during colonization more fully, we used mini-Tn7 transposons to mark bacteria with a...
متن کاملRole for phosphoglucomutase in Vibrio fischeri-Euprymna scolopes symbiosis.
Vibrio fischeri, a luminescent marine bacterium, specifically colonizes the light organ of its symbiotic partner, the Hawaiian squid Euprymna scolopes. In a screen for V. fischeri colonization mutants, we identified a strain that exhibited on average a 10-fold decrease in colonization levels relative to that achieved by wild-type V. fischeri. Further characterization revealed that this defect d...
متن کاملAn exclusive contract: specificity in the Vibrio fischeri-Euprymna scolopes partnership.
In the threatening world of dog eat dog, or rather, fish eat fish, marine animals have adopted many strategies for protection against predators (25). The Hawaiian squid Euprymna scolopes is no exception. When startled, this small, shallowwater invertebrate rapidly swims away while releasing a blob of ink, meant to mimic the form of its body, to fool and detain its would-be predator. In addition...
متن کاملRoles of bacterial regulators in the symbiosis between Vibrio fischeri and Euprymna scolopes.
In a symbiosis, two or more evolutionarily distinct organisms communicate with one another in order to co-exist and co-adapt in their shared environment. The mutualistic symbiosis between the bioluminescent marine bacterium Vibrio fischeri and the Hawaiian squid Euprymna scolopes provides a model system that allows scientists to examine the mechanisms by which this communication occurs (McFall-...
