Enhanced myotoxicity and involvement of both type I and II fibers in monensin-tiamulin toxicosis in pigs

Vet Pathol. 1985 Jul;22(4):409-14. doi: 10.1177/030098588502200417.

Abstract

Simultaneous administration of monensin and tiamulin to pigs resulted in enhanced myotoxicity. Skeletal muscles of tongue, diaphragm and legs were preferentially affected, whereas the masseter, longissimus thoracis and cardiac muscles, including the left auricle, were spared. Histochemical examination revealed an involvement of both type I and II fibers of skeletal muscles.
