PRELIMINARY ASSESSMENT OF SERUM CAPILLARY ZONE ELECTROPHORESIS IN SIX NONDOMESTIC BOVID SPECIES

Area of Science:

• Veterinary Medicine
• Clinical Pathology
• Analytical Chemistry

Background:

• Serum protein electrophoresis is crucial for diagnosing inflammation and gammopathies in veterinary medicine.
• Agarose gel electrophoresis (AGE) has been used in some non-domesticated mammals, but capillary zone electrophoresis (CZE) offers superior resolution and precision.
• CZE is a novel method for analyzing serum proteins, particularly in non-domesticated species.

Purpose of the Study:

• To describe the capillary zone electrophoresis (CZE) electrophoretogram for several wild antelope species.
• To establish preliminary reference intervals for CZE parameters in these species.
• To compare CZE-quantitated albumin with traditional bromocresol green (BCG) methodology.

Main Methods:

• Banked serum samples from adult addax, gemsbok, sable antelope, scimitar horned oryx, waterbuck, and common wildebeest were analyzed using CZE.
• Electrophoretograms were generated, and key parameters like albumin and globulin fractions were quantified.
• Albumin levels from CZE were compared to those obtained using the bromocresol green (BCG) method.

Main Results:

• Distinct CZE electrophoretograms and preliminary reference intervals were established for the studied antelope species.
• Significant interspecies variations in serum protein profiles were observed, notably lower albumin/globulin ratios in addax, gemsbok, and sable antelope due to higher alpha and beta globulins.
• CZE and BCG methods for albumin quantification were significantly correlated (p < 0.01), but BCG tended to overestimate albumin levels.

Conclusions:

• Capillary zone electrophoresis (CZE) is a valuable diagnostic tool for assessing health in wild antelope species.
• CZE reveals significant species-specific differences in serum protein composition, potentially influenced by genetics, subclinical infections, or environmental factors.
• CZE provides a more precise and higher-resolution alternative to traditional methods for veterinary serum protein analysis.
