Biochemical blood profile in 20 female veiled chameleons (Chamaeleo calyptratus) Aged 7, 9 and 11 Months.

Veiled chameleons (Chamaeleo calyptratus) are more frequently presented to veterinary clinics due to reproductive diseases that lead to high morbidity, especially in captive-bred females. The objective of this study was to evaluate blood biochemical profiles of healthy, young captive females veiled chameleons aged seven, nine and eleven months. Blood samples were taken from 20 female veiled chameleons at the age of 7, 9 and 11 months. The biochemical profile was analyzed using the VetScan VS2 analyzer with an Avian/Reptile Profile rotor. The ionized calcium (iCa) concentration was measured by i-STAT analyzer with a CHEM+8 cartridge. Mean concentration of glucose (15.8 ± 1.3 mmol/l) and uric acid (244.3 ± 143.2 µmol/l) at the age of seven months were significantly higher than mean concentrations of glucose (12.8 ± 16.5 mmol/l) and uric acid (134.9 ± 113.2 µmol/l) at nine months of age and mean concentration of glucose (13.2 ± 0.9 mmol/l) and uric acid (129.4 ± 109.2 µmol/l) at 11 months of age, respectively. Total calcium (4.2 ± 0.8 mmol/l) and ionized calcium (1.51 ± 0.16 mmol/l) were significantly higher at seven months of age compare to nin months. Mean activity of aspartate aminotransferase at nine months (6.2 ± 2.3 µkat/l) was significantly higher (P=0.004) than the mean activity of aspartate aminotransferase at seven months of age (4.7 ± 1.0 µkat/l). Concentrations of potassium at eleven months (8.3 ± 2.1 mmol/l) were significantly higher (P ˂ 0.001) than the mean concentration of potassium at seven months (5.4 ± 1.3 mmol/l) and also at ninth months (6.1 ± 1.6 mmol/l). No significant differences were found among the mean concentrations of total protein (57.5 ± 14.6, 61.9 ± 9.2, 59.6 ± 12.2 g/l), albumin (32.8 ± 5.4, 33.6 ± 4.1, 33.4 ± 7.1 g/l), globulin (27.4 ± 5.4, 26.6 ± 4.3, 26.3 ± 5.4 g/l) and mean activity of creatine kinase (25.4 ± 10.3, 30.1 ± 21.0, 25.6 ±13.2 µkat/l) at any of the ages. In all females, ovarian activity was already evident in the first part of monitoring, and the measured values could be interpreted as values for young female veiled chameleons during active ovarian activity.
