Summary
Neonatal isoerythrolysis in foals is caused by mare antibodies attacking foal red blood cells. Early diagnosis and preventative measures, like blood typing mares, are crucial for foal survival.
Area of Science:
- Veterinary Immunology
- Equine Neonatal Medicine
- Reproductive Immunology
Context:
- Neonatal isoerythrolysis (NI) is a significant cause of mortality in newborn foals.
- It arises from immune incompatibility between mare antibodies and foal erythrocytes.
- Understanding the specific erythrocyte antigens involved (Aa and Qa) is key.
Purpose:
- To present a comprehensive overview of neonatal isoerythrolysis in foals.
- To detail the aetiology, pathogenesis, clinical signs, diagnosis, and treatment of NI.
- To highlight diagnostic and preventative strategies for NI in equine neonates.
Summary:
- NI results from mare isoimmunisation to foal's Aa/Qa erythrocyte antigens, leading to haemolysis after foal ingests colostral antibodies.
- Clinical signs appear within 8-96 hours, characterized by anaemia, decreased packed cell volume (PCV), and haemoglobin.
- Diagnosis involves clinical examination, haematological tests, and immunological assays; prevention includes pre-parturition mare blood typing and post-foaling colostrum compatibility tests.
Impact:
- Provides essential information for veterinarians and breeders to diagnose and manage NI.
- Emphasizes the importance of preventative strategies to reduce foal mortality.
- Contributes to improved understanding and outcomes for affected equine neonates.
