Abstract

Objective: Diagnostic evaluation of sporadic incidence of paralysis in fattening pigs weighing up to 60 kg in a herd of 900 animals. Material and methods: A male castrated fattening pig was presented at the Clinic for Swine, Ludwig-Maximilian University of Munich and examined clinically, by laboratory analysis and morphologically. Results: The weaner was in a bad state of nutrition and in lateral recumbency with a head tilt to the right. The animal was unable to stand and walk by itself. Skin perception, the anal reflex as well as the reflex of the dewclaw and interdigital space of all four limbs were maintained. However, the corneal reflex of the right eye was absent. Postmortem examination revealed a bacterial brainstem meningoencephalitis with detection of Arcanobacterium pyogenes. Neuropathological findings suggested an alveolitis and maxillary sinusitis being the origin for centripetal extension of the process via the maxillary nerve. Conclusion and clinical relevance: As a basic cause for paralyses of the limbs in weaners an ascending alveolitis due to tooth fractures or wrongly accomplished zootechnical measures (tooth-pinch) should be considered.
