Anatomomorphological study of Schistosomus reflexus in a cattle
Keywords:

Schistosomus reflexus (SR) is a fatal congenital anomaly of low incidence mainly observed in ruminants. This study aimed to report the occurrence of SR in a cow with dystocia, multiparous, and normal previous deliveries, treated in a property located in Irati, south-central region of Paraná, Brazil. During anamnesis, it was reported that labor occurred normally, with cervical dilation and disruption of the allantoic and amniotic stalk. However, there was no externalization of the fetus. Due to the infeasibility of the forced traction observed in the physical examination, a cesarean was performed. The extracted fetus was misshaped, presenting dorsiflexion of the spine, exposed abdominal organs, ankylosis of limbs, and deformed face, which are anatomical alterations compatible with the characteristics of Schistosomus reflexus described in the literature. The case reported contributes significantly to the improvement of understanding and studies on this disorder, since its occurrence is rare.
