“…In the total WBC count of V. ammodytes, lymphocytes were on average the most common leukocytes (about 50% of total leukocytes), which is in agreement with findings for other vipers (Troiano et al 1997;Dutton and Taylor 2003). Azurophils were the second most common leukocyte type observed.…”

“…The hematocrit (PCV) of V. ammodytes was in the range reported for other reptiles, as was the hemoglobin concentration (Dessauer 1970;Dutton and Taylor 2003). The total RBC count showed a slightly higher value than those reported for captive Bothrops species (Troiano et al 2000), but lower than those reported for captive Crotalus durissus terrificus (Troiano et al 1997), with values mostly similar to those of the king cobra (Ophiophagus hannah, Salakij et al 2002) or some lizards (Sodeinde and Ogunjobi 1994). The MCV revealed that the erythrocytes of V. ammodytes had a typical volume for a reptile, reaching an upper value reported among snakes and lizards (Frye 1991).…”

“…The percentage of basophils in V. ammodytes was lower than those reported for many other reptile species (Frye 1991;Troiano et al 1997). However, in some reptiles, the number of these cells was within the range observed in this study (Knotková et al 2002;Salakij et al 2002).…”

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.

“…The hematological parameters; eosinophils, monocytes, Azurophils, basophils and platelets of different Boa constrictor groups included in the study did not show any significant variation with regard to age or sex, results also found in the study 12 however the ranges derived from monocytes and eosinophils on average are higher than the reported in the literature. 11,13 With respect to the blood chemistry values for glucose, total protein and albumin in blood obtained in the study were not significantly different between groups of males and females and adults and juveniles.…”

In the CAV-AMVA (Center for attention and Evaluation) of wildlife, located in Barbosa Antioquia, belonging to the Area Metropolitana del Valle de Aburra , were taken the data of hematological values of 92 Boa constrictor, which enter to the center from July of 2015 to July of 2016. Once the data were taken, a retrospective descriptive analysis was performed. The reference values for hematology and blood chemistry of Boa constrictor were taken into account: total erythrocyte count (Millions/mm3), total white blood cell count (Thousands/Mm3), differential count of leukocytes "Heterophils (%), lymphocytes (%), eosinófilo (%), basófilos (%) and monocitos (%), trombocytes (G/dl), albumin (g/dl), glucose (mg/dl), hemoglobin (g/dl), mean corpuscular volume, mean corpuscular hemoglobin/Dl), aspartate aminotransferase (AST) (U/L), Alanine aminotransferase (ALT) (U/L), Urea (mg/dl), Phosphorus (mg/dl), Calcium (mg/ dl) and Albumin (g/dl). For the statistical analysis, the animals were divided into 4 groups, considering sex and age: adult females (AF) n=18, young females (JF) n = 10; Adult males (AM) 52; Young males (JM) n = 12. The purpose of the analysis was to evaluate whether there were significant differences between males and females by age groups in each of the variables. One-way ANOVA analysis showed the following results: Hematocrit (Hto %) (P value = 0.150), total RBC count (RTGR Millions/mm3) (P value=0.335) showed no statistically significant differences between the different groups however Hemoglobin (Hb gr/dL) (P value= 0,057) could show a variation between the group of Adult males with the other groups. The variable Heterophils (%) (P valor =0,002) showed statistically significant differences between the group of Adult Females with Young females (P value =0.006) and adult females with young males (P valor =0,031) however there was not differences between de other groups. It was determined in this study that there are no significant differences depending on the variable sex. However, in terms of age, there are significant differences in the parameters of Heterophils and lymphocytes Establishment of hematological parameters in boas (boa constrictor) in the centro de atencion y valoracion de fauna silvestre del valle de aburra (Cav amva) 147 Keywords
