BIOLOGICAL PROPERTIES (IN VITRO) EXHIBITED BY FREE-LIVING AND SYMBIOTIC VIBRIO ISOLATES.
Adhesion and biofilm forming ability of symbiotic bacteria play a crucial role in host colonization and tissue infection. Bacteria benefit by adhering to their host in a manner that allows them to successfully maintain contact for the exchange of nutrients, hormones, or other necessary products. This study examined pili morphology, motility, and biofilm formation exhibited by Vibrio fischeri strains (free-living and symbiotic). Since these symbiotic factors contribute in some fashion to the interaction between V. fischeri and their squid host, variation between strains may be a contributing factor that leads to specificity among different hosts. V. fischeri strains examined in this study demonstrated considerable variation in their biological properties when observed in vitro. In addition to differences observed between strains isolated from several different host species, we observed variation between strains isolated from the same host species from diverse geographical locations. This study suggests that subtle differences in the biological properties of closely related V. fischeri strains may influence the nature of the interaction among V. fischeri and their sepiolid hosts.
期刊介绍:
Vie et Milieu / Life & Environment is an international journal of general ecology publishing papers in English on marine ecology, trophic webs, ecophysiology, quantitative ecology, modelisation, evolution, phylogenetics, genetics, symbioses, environment. The journal is focused on marine sciences, but also publishes studies on lagoonal and terrestrial domains.
