(a) Pseudotuberculosis of Sheep. Pseudotuberculosis ovum. {Cheesy Broncho-pneumonia; Llymphadenitis caseosa ovum.) Occurrence. The disease occurs in some flocks in the form of an epizootic. Thus Turski observed it in 44 sheep in a herd of 150 in western Prussia; von Zeeb in the abattoir of Langensalza, in small herds frequently every animal being affected. The disease has also been reported from the provinces of Hanover and Silesia. Cherri & Bull observed the disease in the abattoirs in Melbourne, Australia, in from 15 to 70% of all slaughtered sheep. According to Norgaard & Mohler it is very common in the western United States of North America and according to Sivori it is very frequent in adult sheep in the Argentine Republic (the last named authorities have furnished exact anatomical and clinical descriptions of the disease). Etiology. The disease is caused by the Bacillus pseudo- tuberculosis ovis (bacillus of Preisz and Nocard). This appears as a delicate immotile rod (Fig. 97), which is non-sporulating and easily stained with aqueous aniline dyes as well as according to Gram's method. In cultures the bacilli are somewhat thicker and longer and have a tendency to develop oval, club-shaped and pear-shaped forms which appear cross-striated when stained. Cultivation. This facultative aerobic bacillus thrives only at body temperature (according to Carre & Bigoteau, also at room temperature) ; on agar it forms gray or yellowish-white colonies which resemble minute scales and which are not readily emulsified; in the deep portions of the me- dium they form a white streak, rat
