Dystocia and cesarean section in a free-ranging ocelot (<i>Leopardus pardalis</i>) after traumatic spinal cord injury resulting from dog (<i>Canis familiaris</i>) attack

Abstract

Background: Ex situ breeding programs are essential to establish genetic resource banks and produce offspring to
strengthen the in situ conservation of endangered species. However, many programs fail to maintain viable ex situ
populations due to reproductive problems, including dystocia in pregnant females. Dystocia encompasses different emergency obstetric situations for the lives of dams and fetuses that require urgent intervention. This condition has been studied in domesticated species but published records in wildlife, specifically in felines species, are scarce.
Case Description: An adult female ocelot (Leopardus pardalis) was referred to the wildlife hospital of the Universidad San Francisco de Quito after being attacked by dogs (Canis familiaris). Neurological tests revealed traumatic spinal cord injury at a thoracolumbar level. Complementary tests (laboratory exams, radiographs, and ultrasound) revealed a full-term pregnancy, failure in the labor progress, and critical fetal stress. A cesarean section was performed, and the newborns received resuscitation care after assessing their viability using the Apgar score system. The neonate with the lowest Apgar score died within the first hour after birth, while the second one showed an increase in Apgar score after resuscitation care and survived the procedure.
Conclusion: We provide new obstetric data that could be relevant to save the lives of dams and newborns in related
cases for ocelots and other species of wild felids. Furthermore, this study confirms the adverse effects that domestic dogs have on wildlife species.
