Using mycobacterium cell wall fraction to decrease equine chorionic gonadotropin after abortion
Abstract Background Equine embryonic loss following the development of endometrial cups delays return to cyclicity due to the production of equine chorionic gonadotropin (eCG). Natural degradation of endometrial cups coincides with an influx of immune cells at 100–120 days of gestation, but therapeutic stimulation of reduced eCG production has been ...
