An outdoor microcosm study was conducted in order to evaluate the kinetics of immunomodulation in rainbow trout (Oncorhynchus mykiss) exposed to liquid creosote. Fish were sampled on d 7, 14, 21, and 28 from microcosms dosed initially with 0, 3, and 10 microl/L of creosote. Pronephros leukocytes were monitored for phagocytic activity, oxidative burst, and surface immunoglobulin-positive (Slg+) B-cell counts. Oxidative burst was inhibited by creosote exposure; however, by sampling d 28, the burst response returned to near control levels. Phagocytic activity, on the other hand, was stimulated, peaking on sampling d 7, then returning to near control levels by d 28. Although control Slg+ B-cell counts were quite variable across sampling days, Slg+ B-cell counts were also elevated in creosote-exposed fish after seven days of exposure. Slg+ B-cell numbers decreased significantly to near control levels during the remainder of the study. The overall results from this study confirm that creosote has the potential to alter certain immune parameters, and emphasize the importance of monitoring changes in the immune system during exposure. Polycyclic aromatic hydrocarbons (PAHs), a major constituent of liquid creosote, are the suspected immune-altering agents.
