Hematological and plasma chemistry values for the African rock python (Python sebae)

Area of Science:

• Herpetology
• Veterinary Medicine
• Wildlife Conservation

Background:

• Hematology and plasma biochemistry are crucial for assessing wildlife health, yet reference values for many snake species are scarce.
• Establishing these values is vital for managing threatened and endangered reptiles.

Purpose of the Study:

• To determine hematology and plasma biochemistry reference values for captive African rock pythons (Python sebae).
• To investigate the influence of age, sex, season, and hemoparasites on these blood parameters.

Main Methods:

• Blood samples were collected from 33 African rock pythons (19 in the rainy season, 14 in the dry season).
• Hematological and plasma biochemistry parameters were analyzed.
• Statistical analysis was performed to assess the effects of age, sex, season, and hemoparasite status.

Main Results:

• Significant seasonal differences were observed in white blood cells (WBC), heterophils, lymphocytes, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), aspartate aminotransferase (AST), red blood cells (RBC), glucose, and total protein.
• Age influenced lymphocyte and monocyte counts.
• No significant differences were found for hemoparasite status, though trends suggested higher WBC, heterophils, and lymphocytes in infected snakes.

Conclusions:

• This study provides the first pilot reference values for African rock python blood parameters.
• Seasonal and age-related variations are important considerations for clinical assessments and future research on this species.
