Abstract
Corynebacterium pseudotuberculosis or caseous lymphadenitis is a common condition in sheep and goats. Two cases are described involving otitis media-interna and, in one case, cerebellar abscessation. The first case began with otitis externa and progressed to cerebellar abscessation, presumably as a result of C. pseudotuberculosis infection based on the macroscopic appearance of the abscess. The second case of otitis media-interna involved C. pseudotuberculosis with parasitic encephalitis or secondary meningo-encephalitis. Caseous lymphadenitis is a worldwide problem in livestock and also has zoonotic implications. Antimicrobial therapy of abscesses is often unrewarding due to the thick encapsulation of the abscesses and the extremely contagious nature of the organism. Alternative measures of treating this condition must be sought. In flocks or herds where caseous lymphadenitis has been diagnosed, it should be considered as a differential diagnosis for neurological conditions. The potential for spread must be kept in mind when it is suspected to be the cause of otitis in livestock.
