Isolation of Acid‐Fast Organisms Resembling Mycobacterium vaccae from a Lesion of Bovine Nodular Thelitis

The incidence of bovine nodular thelitis in Japan was reported by Shimizu et al (2) and Yachida et al (8). Although many acid-fast organisms were found microscopically in lesions of nodular thelitis, no culturable acid-fast organisms could be isolated at that time. Recently, only four isolates resembling but differing from Mycobacterium gordonae were obtained from one of seven cows suffering from nodular thelitis (3). More recently, nine new cases of the same disease were found. From one of them, two isolates resembling Mycobacterium vaccae were obtained. The present paper describes the properties of these organisms. In all nine cases, the lesions were found in the teat. One case showed lesions also in the eyelid and near the anus, and another one also in the escutcheon. The lesions in all cows were histologically similar to tuberculosis and contained many acid-fast organisms. All cows showed positive reactions to tuberculin (PPD, 50 iug)
