Canine and feline abortion diagnostics.
Knowledge of the causes of canine or feline pregnancy loss is limited and the success rate for making a definitive diagnosis is disappointingly low. Although these facts are discouraging, there are some things that can be done to improve success rates. This paper will address limitations and explore ways for improvement. For abortions caused by microbial infections, there are many reasons why it may not possible to identify the agents. "Non-infectious" causes are much more difficult to diagnose, and their relative importance is unknown. These include endocrine failure, underlying endometrial disease, genetic abnormalities, nutritional deficiencies, and toxicosis from drugs or environmental sources. Genetic abnormalities are a major cause of human pregnancy loss, yet we have little specific information about genetic diseases leading to abortion in animals. This paper addresses ways clinicians and diagnosticians can work together to improve diagnostic success. Necropsy techniques for fetal and placental examination and sampling are briefly reviewed. It is hoped that this series of papers will stimulate discussion on the causes and pathogenesis of pregnancy failure, and focus attention on areas where abortion diagnostics can be improved.
