“…Serum biochemistry values for all three species examined were similar to those previously reported in chelonians with the exception of Ca 2+ (Anderson et al, 1997;Diethelm and Stein, 2006;Hidalgo-Vila et al, 2007;Innis et al, 2007;Chung et al, 2009;Rangel-Mendoza et al, 2009;Rossini et al, 2010;Chansue et al, 2011). Calcium was notably higher in the chelonians in this study and is likely to reflect egg production and development (Anderson et al, 1997;Harr et al, 2001).…”

“…The TWBC and leukocyte differentials for all three species examined were similar to those of other freshwater chelonians (Hidalgo-Vila et al, 2007;Chung et al, 2009;Rangel-Mendoza et al, 2009;Rossini et al, 2010;Chansue et al, 2011). Variation in the leukocyte differential counts observed between species is likely to reflect species-specific variation.…”

“…Chelodina longicollis is an obligate carnivore (Chessman, 1984), whereas E. macquarii is an omnivore with filamentous algae constituting approximately 53% of the diet (Spencer et al, 1998). The higher PCV of C. oblonga compared C. longicollis and E. macquarii was still within normal limits of other freshwater turtles (RangelMendoza et al, 2009;Rossini et al, 2010), although TP was higher than in other species of aquatic chelonians (Anderson et al, 1997;Diethelm and Stein, 2006;Hidalgo-Vila et al, 2007;Innis et al, 2007;Perpiñ á n et al, 2008;Chung et al, 2009;Rangel-Mendoza et al, 2009;Rossini et al, 2010;Chansue et al, 2011). The increased erythrocyte volume and serum protein in C. oblonga may be normal in this species or it could possibly reflect mild dehydration at the time of sampling FIGURE 1.…”

ABSTRACT:Hematologic and serum biochemical analyses were performed on 30 wild-caught, gravid, Australian freshwater chelonians. Species sampled were western long-necked turtles (Chelodina oblonga; n513), common long-necked turtles (Chelodina longicollis; n58), and Murray River turtles (Emydura macquarii; n59). Turtles were obtained from Lake Goolellal in Perth, Western Australia (C. oblonga), and Lake Coranderrk in Healesville, Victoria (C. longicollis and E. macquarii). All turtles were considered healthy at the time of sample collection. Blood results were similar to those reported in other freshwater chelonians, with the exception of elevated calcium levels in all species. Hypercalcemia was attributed to egg development and maturation. A hemoparasite morphologically resembling Haemogregarina clelandi was found in all C. oblonga samples and in four C. longicollis samples. Infection with H. clelandi appeared to have no physiological effects on blood parameters or morphometrics of infected turtles. Blood parameters were also considered poor indicators of female chelonian morphometrics and fecundity.

“…Afecções hepáticas de causas variadas, rinites, pneumonias, broncopneumonias infecciosas, endoparasitoses e hemoparasitoses estão entre as principais enfermidades que acometem as tartarugas, sendo as possíveis responsáveis por diferentes graus de anemia e até mesmo a morte destes animais (Rossini et al 2012). Além disso, variações fisiológicas dos constituintes séricos de répteis podem ocorrer devido à alimentação, tempo de apnéia, variações na temperatura corporal, disponibilidade de água, ciclo reprodutivo, estação do ano, idade e hibernação (Christopher et al 1999).…”

RESUMO: Amostras de sangue de Tartaruga-da-Amazônia mantidas em cativeiro foram analisadas com o propósito de avaliar os constituintes bioquímicos séricos e de relacionar ao que já foi relatado por outros pesquisadores, além de gerar mais informações, tendo em vista a escassez de dados envolvendo a espécie estudada. Foram utilizados 35 animais, com idade entre 3 e 7 meses, os quais foram contidos fisicamente para coleta de sangue em tubo sem anticoagulante. As análises bioquímicas foram processadas através de métodos cinéticos (enzimas) e colorimétricos (demais análises), e os valores médios obtidos foram: cálcio 7,0±1,9mg/dL, fóforo 2,8±1,2mg/dL, ácido úrico 1,8±0,8mg/dL, uréia 10,4±3,9mg/dL, alanina aminotransferase (AST) 75,5±33,6 UI/L, proteína total 1,9±0,8g/dL, triglicerídeos 22,9±9,8mg/dL e colesterol 45,3±19,7mg/dL. Observou-se que os valores dos componentes séricos avaliados assemelham-se aos que foram encontrados por outros pesquisadores em estudos bioquímicos séricos com Podocnemis expansa e outras tartarugas de água doce. Importante ressaltar que, no decorrer deste estudo observou-se a escassez de dados publicados sobre parâmetros sanguíneos de tartarugas do gênero Podocnemis, especialmente a espécie Podocnemis expansa, o que corroborou a alta relevância do desenvolvimento de mais pesquisas que envolvam a questão.

“…When the body mass of the individuals was not available from the source but only SVL or CL was given, body mass was estimated from SVL or CL using published allometric equations [15][16][17]. For Podocnemis spp., no corresponding equation was published; therefore, we derived our own BM-CL regression equation based on data from various sources [18][19][20][21][22][23][24].…”
