Bovine auto-immune haemolytic anaemia

Area of Science:

• Veterinary Medicine
• Immunology
• Hematology

Background:

• Autoimmune haemolytic anaemia (AHA) is a rare condition in cattle.
• Clinical signs can include anemia and dyspnea, often leading to rapid deterioration.

Observation:

• A six-month-old heifer presented with acute anaemia and dyspnoea.
• Clinical signs progressed rapidly over a two-day period.

Findings:

• The heifer exhibited auto-agglutination, a clumping of red blood cells.
• Coomb's testing confirmed the presence of antibovine IgG antibodies on erythrocyte surfaces, confirming AHA.

Implications:

• This case highlights the importance of diagnostic testing for AHA in young cattle presenting with severe anaemia.
• Understanding the immunological basis of AHA can aid in developing targeted therapies.
