An Evans blue dye injection technique was employed to compare vascular
leakage into various regions of the alimentary canal of uninfected an
d Leptorhynchoides thecatus-infected green sunfish, Lepomis cyanellus.
Results revealed no significant difference in permeability to dye amo
ng cecal, between cecal, and intestinal regions. Additionally, L. thec
atus appeared to have neither a systemic nor local effect on mucosal p
ermeability as there was no significant difference in leakage between
infected and uninfected fish or between occupied and unoccupied ceca w
ithin infected fish. Consequently, differential permeability of mucosa
l regions to plasma proteins is unlikely to be a factor in the localiz
ation of L. thecatus in green sunfish.
