Production of interferon by alveolar macrophages.

Acton, Jean D. (Bowman Gray School of Medicine, Winston-Salem, N.C.), and Quentin N. Myrvik. Production of interferon by alveolar macrophages. J. Bacteriol. 91:2300-2304. 1966.-Rabbit alveolar macrophages inoculated with parainfluenza-3 virus in vitro produce a viral inhibitor which possesses the properties of interferon. The interferon is nondialyzable, is stable at pH 4, is not sedimented at 100,000 x g, exhibits species specificity, and can passively protect other alveolar macrophages from infection with virulent rabbitpox virus. The possible significance of alveolar macrophage-produced interferon is discussed.

In vitro interactions between rabbit alveolar macrophages and Pasteurella tularensis.

Nutter, J. E. (Fort Detrick, Frederick, Md.), and Q. N. Myrvik. In vitro interactions between rabbit alveolar macrophages and Pasteurella tularensis. J. Bacteriol. 92:645-651. 1966.-Rabbit alveolar macrophages were successfully employed in a study of host cell-Pasteurella tularensis interactions in vitro. Under cell culture conditions in which inhibitory antibiotics were not employed and small infection ratios were used, the relative in vivo virulence of two strains of P. tularensis was duplicated. As a consequence of intracellular multiplication, normal macrophages were killed in relation to the virulence of the strain employed. Alveolar macrophages were also collected from immune rabbits, and macrophage mortality and bacterial growth were significantly suppressed below levels observed with normal macrophage preparations. The effect of immune serum could only be ascribed a minor role in the observed reactions. A marked intravenous toxicity of P. tularensis for the rabbit was observed with both virulent and attenuated strains. The toxicity was possessed only by viable preparations and could be elicited in animals immune to virulent challenge.
