ABSTRACT
Contamination with bacterial or fungal organisms may potentially be recognized clinically by: 1) detection of an abnormal uterine environment prior to breeding by culture, cytology or biopsy, 2) presence of echogenic fluid in the uterus after breeding (rule out non-infectious persistent mating-induced endometritis), 3) presence of debris in the media recovered during the embryo collection procedure, or 4) presence of debris adhered to the embryo. Contamination with a viral agent, such as equine arteritis virus (EAV) or equine herpesvirus type-1 (EHV-1), would be much more difficult to detect clinically.
