Abstract

The Old World non-human primates (NHP) - baboons (Papio spp.) share similarities with humans regarding fetal and placental development and some pregnancy-related complications. Information about the mechanism of birth and complications arising during parturition in these species is relatively sparse. In this manuscript, we add information from a series of pathological and observational cases to highlight insights and selected complications of birth in Papio spp, based on video-recording of the delivery process, X-ray, MRI, and ultrasound evaluations in pregnant baboons. Additionally, we abstracted pathology records obtained from perinatal loss in a large baboon colony during a 17 year period. The presented cases provide important information for the management of pregnancy and delivery in Papio spp.

  • The Old World non-human primates (NHP) - baboons (Papio spp.) share similarities with humans regarding fetal and placental development and some pregnancy-related complications

  • We add information from a series of pathological and observational cases to highlight insights and selected complications of birth in Papio spp. based on video-recording of the delivery process, X-ray, MRI and ultrasound evaluations in pregnant baboons, and pathology records obtained from perinatal loss in a large baboon colony during a 17 year period[5,16]

  • Pathology records (17 years) of the baboon colony were analyzed for the presence of dystocia and selected cases with documented diagnosis of dystocia are reviewed in the present manuscript

Summary

Introduction

The Old World non-human primates (NHP) - baboons (Papio spp.) share similarities with humans regarding fetal and placental development and some pregnancy-related complications. The author catalogued a number of observations on conditions associated with reproductive success in this colony and reported several characteristics of baboon parturition including the relative frequency of fetal presentation in labor (most often a face presentation with the head fully extended) and that the vast majority of births happened at night. The uterine contractility patterns around the time of deliveries have been described in detail[11,12] direct observations of the birthing process have only rarely been reported[9,13,14,15] In this manuscript, we add information from a series of pathological and observational cases to highlight insights and selected complications of birth in Papio spp. based on video-recording of the delivery process, X-ray, MRI and ultrasound evaluations in pregnant baboons, and pathology records obtained from perinatal loss in a large baboon colony during a 17 year period[5,16]
