- Cold-water fish pathogen V. salmonicida establishes a pathogenic relationship with salmon and trout.
- Luminous bacterium V. fischeri both establishes and maintains a symbiotic association with the Hawaiian sepiolid squid Euprymna scolopes.
- Phylogeny, physiology, and distribution of resident gut microbes within herbivorous marine fishes indigenous to the California coast.
- Symbiotic and pathogenic associations of marine Vibrio spp. with their animal hosts.
Further Research Details
Pat Fidopiastis is a microbiologist specializing in symbiotic and pathogenic associations of marine Vibrio spp. with their animal hosts. In particular, Dr. Fidopiastis studies the mechanisms by which the luminous bacterium V. fischeri both establishes and maintains a symbiotic association with the Hawaiian sepiolid squid Euprymna scolopes.
This association is emerging as a model for better understanding how Gram negative bacteria in general establish and maintain symbiotic and pathogenic associations with humans. The Fidopiastis lab also studies the mechanisms by which the cold-water fish pathogen V. salmonicida establishes a pathogenic relationship with salmon and trout.
This lab uses the latest tools in molecular biology to identify, isolate, and characterize Vibrio genes whose products might be involved in their symbiotic or pathogenic niches. The Fidopiastis lab has begun an in-depth analysis of the phylogeny, physiology, and distribution of resident gut microbes within herbivorous marine fishes indigenous to the California coast.
