Canine and feline abortion diagnostics

Area of Science:

• Veterinary Medicine
• Reproductive Biology
• Animal Pathology

Background:

• Canine and feline pregnancy loss diagnosis is challenging with low success rates.
• Understanding the causes of abortion in companion animals remains limited.
• Microbial infections and non-infectious factors contribute to pregnancy failure.

Purpose of the Study:

• To address limitations in diagnosing canine and feline pregnancy loss.
• To explore strategies for improving diagnostic success rates.
• To stimulate discussion on causes and pathogenesis of pregnancy failure.

Main Methods:

• Review of current knowledge on causes of pregnancy loss.
• Discussion of challenges in identifying infectious agents.
• Exploration of non-infectious causes like endocrine failure and genetic abnormalities.
• Brief review of necropsy techniques for fetal and placental examination.

Main Results:

• Many microbial agents causing abortion are difficult to identify.
• Non-infectious causes (endocrine, endometrial, genetic, nutritional, toxicosis) are poorly understood and difficult to diagnose.
• Genetic abnormalities are a significant cause of human pregnancy loss, but their role in animals is understudied.
• Collaboration between clinicians and diagnosticians is key to improving outcomes.

Conclusions:

• Enhanced diagnostic approaches are needed for canine and feline pregnancy loss.
• Further research into non-infectious causes, particularly genetic factors, is essential.
• Improved necropsy and sampling techniques can aid diagnosis.
