Aeromonas Hydrophila as an Agent of Infection in Alligators. Phase II, Final Report; Phase III, Partial Report. Progress Report, September 1, 1976--September 30, 1977, Part II

摘要

Studies on experimental alligators exposed to Aeromonas hydrophila showed that alligators are sensitive to heat, handling, and bacterial stress, and they react to this stimulation by predictable defensive mechanisms including increased WBCs, increased antibodies, increases in the alpha sub 2 : albumin peak on quick scan electrophoresis, and by lesions and possibly death if they are unable to produce adequate defenses. Extensive lesions are more likely to develop on alligators kept in 30 to 35 exp 0 C water, with death also most likely at these temperatures. Feeding the alligators apparently upset the biological balance in the holding tanks because different bacteria were dominant at different temperatures, few A. hydrophila were found in lesions or internal organs of dead or live alligators, and control alligators in warm water were as likely to become infected and die as were experimental alligators.
