In Vitro Transfer of Cellular Immunity of Mouse Phagocytes in Experimental Salmonellosis.

4:505, 1960). Each rabbit was prebled to assure that its serum was noninhibitory for the growth of PPLO. Two control rabbits were included in this study. One was inoculated with the sediment from 1 liter of the same broth medium which had been incubated but not inoculated with PPLO. The other rabbit served as an uninoculated control. The growth-inhibition test (Fabricant, Avian Diseases 4:505, 1960) using the solid medium described by Chalquest (Avian Diseases 6:36, 1962) was conducted with these organisms and their homologous antisera. Specific antisera were produced by this procedure for each of the three isolates and would completely inhibit the growth of the homologous culture when 5% of the antiserum was incorporated into the solid medium. None of the control rabbit sera inhibited the growth of any of these isolates. Additional testing is needed to determine whether or not there is any serological relationship between these various isolates.
