The purpose of the study was to establish the reference interval for blood leukocytesfrom captive northeastern Argentine caimans, as well as to detect physiological variationsrelated to species, sex, age, year season, and handling system. Samples from 223 healthysub–adults, both sexes specimens of C...

The purpose of the study was to establish the reference interval for blood leukocytesfrom captive northeastern Argentine caimans, as well as to detect physiological variationsrelated to species, sex, age, year season, and handling system. Samples from 223 healthysub–adults, both sexes specimens of Caiman latirostris (n = 109) and Caiman yacare (n =114), were obtained. White blood cells concentration (13.7±2.5 G/l) and proportion of heterophils(17.5±3.4%), lymphocytes (75.0±6.8%), monocytes (5.3±1.1%), eosinophils (2.2±0.4%),and basophils (0.3±0.05%) were determined by reptilian specific techniques. For each type ofcell, largest diameters were, respectively: 14.49±1.54; 8.70±1.01; 12.74±1.85; 12.55±2.15 and10.77±1.02 um. Heterophils rate was significantly higher in C. yacare than in C. latirostris (p< 0.05); lymphocytes rate showed an inverse relationship between species. Lymphocytes proportionwas significantly higher in females than in males. The growth progress was reflectedin slight heterophils decrease and lymphocytes increase. Total leukocytes concentration andlymphocytes percentage were significantly lower in autumn and winter. Decreases of heterophils(not significant) and monocytes (significant) were registered in summer and spring.Greater leukocytal differences attributable to handling systems (housing, feeding) used ina hatchery and a zoo, were not verified. Obtained data are applicable for the diagnosis andprevention of diseases in these species.
