“…Some lizards show high values of the total WBC count (Sodeinde and Ogunjobi 1994), which is near the maximum value recorded for V. ammodytes. Wojtaszek (1991) reported TT count in Natrix natrix ranging from 32 to 34 × 10 9 /L, depending on the sex, similar to results of the present study. The thrombocyte/leukocyte ratio was approximately 2 for N. natrix, compared to 1.5 for V. ammodytes.…”

“…The ESR is a parameter rarely determined in reptiles. We obtained results that are very similar to those reported by Wojtaszek (1991) (mean ESR for a grass snake of 5.56 mm/h vs. a The ratio between different erythrocyte types indicates normal erythropoiesis activity, but it may also be evidence of pathological changes. For example, a lack of a balance in the juvenile/mature erythrocyte ratio may indicate an ongoing disease (Campbell 2006;Oliveira-Junior et al 2009).…”

“…Azurophils were the second most common leukocyte type observed. Azurophils were reported in reptilian blood by some authors (Troiano et al 2000), but not by others (Wojtaszek 1991). Blood of V. ammodytes had a high azurophil count compared to that of other reptiles (Campbell and Ellis 2007), but was similar to that reported for a wild population of king cobra (Salakij et al 2002).…”

“…Hematological parameters may be useful for assessing the general health status of the animal, particularly dehydration or anemia (Dessauer 1970;Campbell 2006). In some reptiles, males have a higher PCV, hemoglobin concentration, and total RBC count than females (Duguy 1970;Wojtaszek 1991). In contrast, a study on green iguanas showed that females had higher PCV, hemoglobin concentration, and MCHC values than males (Harr et al 2001).…”

Biochemical and hematological profiles of a wild population of the nose-horned viper Vipera ammodytes (Serpentes: Viperidae) during autumn, with a morphological assessment of blood cells

Background: Hematological and biochemical analyses of blood can be of great importance for studying the biology of species and determining the health status of animals in both the wild and captivity. In order to determine baseline ranges for the nose-horned viper Vipera ammodytes, we determined the blood cell morphology and measured 20 hematological and 5 biochemical variables from the blood samples taken from 31 (17 males and 14 females) healthy specimens of nose-horned viper caught in the wild at the beginning of autumn. Results: Most of the measured parameters and blood cell morphology were similar to those reported for other reptile species. The males showed a significantly higher eosinophil count and higher mean cell hemoglobin (MCH) and MCH concentration values, while the females had a significantly higher mature erythrocyte count. The erythrocyte differential counts showed balanced hematopoiesis in this part of the annual cycle. Conclusions: We suggest that these results can be used as a baseline for determining hematological values and blood cell morphology for V. ammodytes, as well as in further studies including monitoring and determination of the health status of this species, especially of animals kept in captivity for antiserum production. This is the most complete report regarding hematological parameters of this endangered snake species.

ABSTRACT:Hematology and plasma biochemistry parameters are useful in the assessment and management of threatened and endangered species. Although reference ranges are readily available for many mammalian species, reference ranges for snakes are lacking for most species. We determined hematology and plasma biochemistry reference ranges for giant garter snakes (Thamnophis gigas) and valley garter snakes (Thamnophis sirtalis fitchi) living in four management areas in the Central Valley of California. White blood cell, heterophil, lymphocyte, and azurophil counts in giant garter snakes were approximately twice the values of valley garter snakes. Statistically significant differences in aspartate aminotransferase, globulin, and potassium between the two species did not appear clinically significant. No significant differences were found in the measured parameters between male and female giant garter snakes. Some differences were found among collection sites. These reference ranges provide baseline data for comparisons over time and between collection sites.
