During the current contract year, the following results were obtained: (1) Data from field-generated studies have shown that hematocrit, hemoglobin, total red blood cell counts, total white blood cell counts, and cortisol levels are significantly affected in largemouth bass with body conditions < 2.0, suggesting that stress, body condition, and the probability of bass acquiring red-sore disease are related. Laboratory studies appear to at least partially confirm these results. (2) Chemotaxis studies show that Aeromonas hydrophila is attracted to specific sugars and amino acids and that there appears to be a strain-related affect of fish mucous on A. hydrophila isolated from red-sore lesions. (3) Immunologic and serologic tests suggest that A. hydrophila isolated from red-sore lesions on bass from one lake system will not cross-react with antibodies in sera isolated from bass in another lake system, suggesting the existence of different strains in different lakes.
