Schistosomus reflexus in a Romanian Black and White calf

Ioana Nicolae, Andra Sipos, Dinu Gavojdian

Abstract


The aim of the current study was to describe both anatomically and cytogenetically a Schistosomus reflexus (SR) case of a Romanian Black Spotted calf. The SR was examined and the necropsy revealed a malformed foetus with chest wall exposing abdominal viscera, marked spinal inversion that produced a distinctive ventral convex curvature. The head and neck of the calf were fully formed, with a normal size and shape, covered in hair with clear colour patterns (markings) typical for the Romanian Black and White breed. All four limbs were ankylosed, there was no motion in the joints, having been orientated parallel to the mandibula and exceeding the head’s length. As well as the identification of the aetiology in developmental abnormalities in cattle is extremely difficult, with known causes of Schistosomus reflexus being conflicting and largely ambiguous, the cytogenetic investigation was carried out. The chromosomal instability identified at the malformed calf’s mother was characterized by a high rate of SCEs and could be related with the presence of different environmental toxic agents.
