Acute cysticercosis caused by Cysticercus tenuicollis in lambs

Abstract

Abstract Twelve 30‐ to 75‐day‐old mixed breed lambs were examined in an intensive system because of sudden recumbency and death. Clinical examination revealed sudden recumbency, visceral pain, and auscultation of respiratory crackles. Lambs died shortly (between 30 minutes and 3 hours) after the onset of clinical signs. The lambs were necropsied, and after routine parasitology, bacteriology and histopathology procedures, the occurrence of acute cysticercosis caused by Cysticercus tenuicollis was confirmed. The use of the suspect infested feed (newly purchased starter concentrate) was discontinued and other lambs of the flock were treated with praziquantel (15 mg/kg, single dose, orally). After these actions, no new cases were observed. The present study showed the importance of preventive measures against cysticercosis in intensive sheep farming systems which include proper storage of feed, preventing feed and environmental access by potential definitive hosts, and implementing consistent parasite control programs in dogs that are in contact with sheep.
