“…On average, body temperatures of free-ranging juveniles (37.4 ± 0.4 °C ) were higher than those of captive juveniles (35.2 ± 0.2 °C) (Alberts & Grant, 1997). Although elevated cholesterol in reptiles is often associated with estrogen production and vitellogenesis (Jackson, Holcomb & Jackson, 1974;Taylor & Jacobson, 1982;Raphael et al, 1994), none of the females in the present study were reproductively mature, and no differences in cholesterol levels between the sexes were observed.…”

A serious concern with the increasing use of translocation and reintroduction in animal conservation programs is the potential for disease transmission between captive and free-ranging populations. As part of an experimental headstarting program, 45 juvenile Cuban iguanas, Cyclura nubila, were artificially incubated, maintained in captivity for six to 18 months, and subsequently released into natural areas on the US Naval Base at Guantánamo Bay, Cuba. Prior to release, all animals underwent physical examinations, hematological analyses, plasma biochemical determinations, and blood and fecal parasite screening. Comparable data were collected from free-ranging juveniles to establish normal baseline values. Although all hematological parameters were within expected ranges for healthy reptiles, captive juveniles exhibited higher total leukocyte counts and percent lymphocytes, but lower percent heterophils, than free-ranging juveniles. All biochemical values other than lactate dehydrogenase and creatine phosphokinase were within normal ranges. Although higher than reported in other species, these enzymes did not differ in captive and free-ranging juveniles. Free-ranging juveniles significantly exceeded captive juveniles in levels of potassium, alkaline phosphatase, lactate dehydrogenase, total protein, cholesterol and triglycerides, whereas the reverse was true for carbon dioxide and glucose. Although free-ranging juveniles exhibited oxyurids and coccidian oocysts in their feces, captive juveniles were negative for the presence of these parasites. Electron microscopy confirmed that a high percentage of both captive and free-ranging juveniles possessed erythrocytes infected with the piroplasm Sauroplasma. Implications of these results for successful repatriation of captive-reared iguanas are discussed.

“…There were significant differences in calcium, cholesterol, and triglyceride values between the sexes and among seasons. Higher values in females than in males, and in mating than in non-mating seasons are consistent with the occurrence of egg production and vitellogenesis (Dessauer 1970;Jackson et al 1974;Anderson et al 1997;Christopher 1999;Zaias et al 2006), because higher circulating calcium will support the demand for egg-shell production, and circulating protein, cholesterol, and triglyceride are main materials for follicular development.…”

Background: The International Union for Conservation of Nature considers the yellow pond turtle Mauremys mutica to be an endangered species. Hematologic analyses are useful tools for monitoring the health, disease processes, and physiologic status of reptiles by clinicians and conservationists. The objectives of this study were to measure plasma biochemical values in healthy captive yellow pond turtles, determine reference values, and evaluate the effects of sex and season on the results. Blood samples were taken from the jugular vein of 53 adult captive individuals (18 males and 35 females) in four different months that represented summer, winter, fall, and spring in Taiwan. Plasma biochemical assays were performed using an automatic analyzer. Descriptive statistics and distributions of each data variable were analyzed using SAS software. Results: Hematological and plasma biochemical reference values of the yellow pond turtle were determined in this study. There were no significant sex differences in hematological values; however, there were seasonal differences, and interactions between sex and season were observed. In females, lactate dehydrogenase, uric acid, calcium, cholesterol, and triglyceride concentrations were significantly higher than in males. There were seasonal differences but no sex and season interactions in serum biochemical values. Conclusions: This information can serve as baseline reference data for future health assessment studies of free-ranging and captive M. mutica, and for epidemiologic, conservation, and captive-breeding studies.

“…The haematologic and plasma biochemical data of several species of turtles have been studied by many authors (KAPLAN 1960; SHEELER and BARBER, 1964; THORSON, 1968; JACKSON et al, 1974;SEIDEL and REYNOLDS, 1980; STURBAUM and BERGMANN, 1981;TAYLOR and JACOBSON, 1982;ALLEMAN et al, 1992;CHRISTOPHER et al, 1994).

“…According to DANTZLER and SCHMIDT-NIELSEN (1966), G. agassiei obtains water chiefly from a herbivorous diet. Most published observations on blood values of desert tortoises are limited to GpheruspoErphemus (HARTMAN and LESSLER, 1964;FRIAR, 1964;SEAL, 1964; THORSON, 1968; JACKSON et al, 1974;TAYLOR and JACOBSON, 1982), with relatively little information available on G. agassiei (BABUDIERI, 1939;ROSSKOPF, 1982;ALLEMAN et al, 1992;O'CON-NER et d., 1994;CHRISTOPHER et al, 1994;GO-ITDENKER and JACOBSON, 1995).…”

The body weight and blood profile were determined in the adult wild West African hinge-backed tortoise, Knkys emsa and the adult wild desert tortoise, Gopherus agassiei kept under identical environmental conditions. A comparison between sexes showed the male X emsa had significantly higher packed cell volume and haemoglobin concentration and lower body weight and plasma alkaline phosphatase values than the female, while no significant sex differences appeared in these parameters in G. uga.rsi @. The haematological parameters and plasma levels of electrolytes, enzymes, proteins and metabolites did not differ significantly between the two species, suggesting that the blood values of X emu resembled those of G ugassiei under identical environmental conditions.
