Abstract

Congenital anomalies are an heterogeneous group of lesions characterized bymorphological changes already present at birth. In small ruminants, a large number ofmalformations have been described by there is scarcity of studies that jointly examine itsfrequency of presentation. In this work, a retrospective revision of cases showing congenitalanomalies found in the Pathology Diagnostic Service of the University of León, between2001 and 2016, when 2437 small ruminant cases were examined, has been carried out. Themost commonly found malformations were seen in the central nervous system: cerebellarhypoplasia and hydranencephaly, related in some animals with pestivirus infection,or lyssencephaly, associated a deficiency in reelin protein. Arthrogriposis was also acommon finding –related to pestivirus in some cases- together with spinal cord anomalies,microcephaly, acephaly, bicephaly, cleft palate or brachygnatia inferior. In the skin, cases ofbullous epidermolysis have been recorded, and the defective proteins identified. In visceralorgans, the highest number of anomalies occurred in the heart, particularly ventricularseptal defects, usually related to clinical signs. Other malformations, in sporadic cases, werecongenital hepatic fibrosis, urinary tract atresia, diaphragmatic hernia or fetal monsters.
