Abstract
The relationship between the visceral form of caseous lymphadenitis (pseudotuberculosis) and a chronic debilitating condition of emaciated mature sheep was investigated. Internal abscesses were dound during necropsy in 80 % of these animals and Corynebacterium pseudotuberculosis was isolated from 87.5 % of the animals with internal abscess other pyogenic bacteria including A. pyogenes, R. equi, epidermidis, S. aureus and P. aeruginosa were also isolated in association with C.pseudotuberculosis. Moraxella spp. was isolated in 37.5 % of the animals with internal abscesses. In some abscesses, Moraxella spp was the predominant microorganism isolated and in others, they were associated with C.pseudotuberculosis. The results indicated that  the visceral form of caseous lymphadenitis is either an important contributing factor to the deveiopment of Gdebilitation and emaciation of sheep or that the debilitating condition and emaciation of sheep may be act as a predisposing factor for development of visceral caseous lymphadenitis. A skin test (allergin) prepared by sonicating C. pseudotuberculosis proved to be of limited value in detecting animals infected with visceral caseous lymphadenitis. Only 52.4 % of the animals with abscesses caused by C.pseudotuberculosis gave positive delayed type hypersensitivity skin test responses. The susceptibility of most predominant isolates to various chemotherapeutic agents were briefly discussed.
