In five calves experimentally infected with Mycobacterium avium and in 10 with M johnei it was shown that the serological response by the fluorescent antibody (FA) test was specific. The serological response in the M avium infected calves was transit

Aspects of protein metabolism in sheep and mice which had been experimentally infected with Mycobacterium johnei were studied by both in vivo and in vitro techniques. Hepatic proteins synthesis was measured by the rate of incorporation of U- 14 C leu

Sheep were experimentally infected orally with Mycobacterium johnei and their immune response assessed by measurement of delayed-type skin hypersensitivity, viable unit counts of M. johnei in the tissues, and by pathology, histochemistry and serial b

The addition of I. N. H. to Lowenstein medium has no effect on the growth of Mycobacterium johnei. In 33.6 per cent of 527 specimens where culture gave positive result, direct microscopy had not revealed the presence of Johne organisms. In 39.7 per c

SUMMARY A rimino phenazine, B663, was found to be active in vitro against 18 strains of Mycobacterium johnei . It inhibited the establishment of experimental oral infection with M. johnei in mice and reduced the level of intestinal infection in sheep

Summary An electron microscopical study was made of Mycobacterium johnei in fluid culture and in the small intestine of C57 black mice. Organisms in culture revealed a cell wall of about 60 to 130 A in thickness. Separating this from the cytoplasm wa

Sheep were vaccinated with heat killed M. johnei adjuvant vaccine and an adjuvant vaccine containing peptidoglycolipid ( PMKO J ) extracted from M. johnei. The M. johnei adjuvant vaccine caused a moderate to high level of hypersensitivity to tubercul

The allergenicity of three vaccinal strains of Mycobacterium johnei was studied by means of comparative johnin and tuberculin tests in groups of guinea-pigs sensitized with each of the different strains. The degree of skin sensitization elicited by o
