Cells isolated from the pronephros of carp were incubated in vitro with the organophosphorus insecticide trichlorfon or dichlorvos, each of which is used in aquaculture to eliminate fish ectoparasites. Dose-dependent suppressive effects were observed in assays for lymphocyte proliferation and myeloid cell respiratory burst activities. Dichlorvos given by bath in vivo did not affect antibody production against Yersinia ruckeri even if the spleen and kidney were obviously contaminated according to acetylcholinesterase activity analysis. Some blood parameters of nonspecific immunity (ceruloplasmin, lysozyme, hemagglutinins) were slightly affected.

The organophosphorus insecticide trichlorphon was tested at medium (10 and 20 ppm) and high concentrations (20,000 ppm) on antibody production against Yersinia ruckeri vaccine. No statistically significant effect was observed on humoral response or on hematocrit. Contamination of organs was analyzed by acetylcholinesterase activity. At 20,000 ppm only liver and brain were highly contaminated; spleen and lymphocytes were not significantly contaminated. At 20 ppm no residue was found in organs.
