Abstract
A crude cell wall fraction of Listeria monocytogenes was prepared by sonic disruption and differential centrifugation of viable, washed cultures. When injected into mice, this sterile, crude cell wall fraction protected mice against an intraperitoneal challenge with 18 to 85 50% mean lethal dose of L. monocytogenes. Resistance was greatly enhanced when bacterial endotoxin (lipopolysaccharide) was injected along with the cell wall fraction. Resistance was measured both by enumerating the bacteria in the livers and spleens of vaccinated and control mice and by survival studies. Two major lines of evidence suggest that the resistance induced by cell wall fraction is at least in part specific. Unlike non-specific resistance, the cell wall fraction-induced resistance was relatively long-lived, (i.e., it was demonstrable 6 weeks after the last injection of cell wall fraction and lipopolysaccharide). In addition, cell wall fraction protected against challenge with L. monocytogenes, but not against challenge with S. typhimurium.

Abstract
A transposon insertion mutant of Listeria monocytogenes was shown to be deficient in prephenate dehydratase, an enzyme acting late in the pathway for biosynthesis of phenylalanine. This mutant had reduced virulence in mice. The mutant and parent strains persisted to the same extent in the tissues of infected mice and elicited similar degrees of splenomegaly. Mice vaccinated with the mutant were protected significantly from subsequent challenge with virulent L. monocytogenes.

Abstract
We studied the effects of administration of recombinant interleukin-1 alpha (rIL-1 alpha) to mice after immunization with killed Listeria monocytogenes cells on the promotion of the functional differentiation of T cells in vivo. Mice immunized with killed L. monocytogenes were unable to express cell-mediated immunity to specific antigen in vivo, as determined by delayed-type hypersensitivity (DTH) and acquired cellular resistance (ACR), and splenic T cells obtained from such mice were unable to respond to rIL-2 and specific antigen and to produce IL-2 after antigenic restimulation in vitro. When rIL-1 alpha was given to mice after immunization with killed bacteria. T cells became capable of responding to rIL-2 and specific antigen in vitro. These functions of T cells were similar to those from mice immunized with viable listeriae. Moreover, using a local passive transfer system, it was found that effector T cells mediating DTH but not ACR to L. monocytogenes were generated in mice treated with rIL-1 alpha after immunization with killed bacteria. These T cells were able to produce macrophage chemotactic factor but not macrophage-activating factor or gamma interferon in vitro in response to stimulation with specific antigen. These results suggest that in vivo administration of rIL-1 alpha facilitates the maturation of antigen-specific T cells mediating DTH and that different effector T cells mediating DTH or ACR are involved in cell-mediated immunity to L. monocytogenes.

Abstract
We established an in vitro system generating L. monocytogenes-specific T cells primarily from unprimed spleen cells of mice. Normal spleen cells were cultured for 5 days in the presence of L. monocytogenes in vitro. Viable cells were harvested and assessed for their capacity to confer acquired cellular resistance (ACR) and delayed footpad reaction (DFR) upon local passive transfer to naive syngeneic recipient mice. When normal spleen cells were stimulated with viable L. monocytogenes, the viable cells that were recovered after 5 days of culture conferred a high level of ACR and DFR. Negative selection revealed that the effector cells obtained in primary in vitro culture were Thy 1+, L3T4+, Lyt2- cells. T cells mediating ACR could not be generated in the culture of normal spleen cells with heat-killed bacteria; however, cells mediating only DFR were generated in the presence of a large number of killed L. monocytogenes. The expression of DFR and ACR by T cells generated in this primary culture system was Listeria-specific; reactions were not observed against unrelated bacterial antigens including S. typhimurium, S. aureus, E. coli and PPD. FACS analysis of the cells in culture showed that L3T4+ and Lyt2- T cells were being enriched during culture. The primary generation of antigen-specific T cells in vitro was also possible with spleen cells from NTx mice but not with cells from nude mice, suggesting the presence of Listeria-specific precursors in NTx mice.

Abstract
Different strains of Listeria monocytogenes serovar 1/2a were used to infect mice. A smooth, haemolytic strain multiplied in the spleen of normal adult mice and induced a long-lasting immunity to subsequent challenge infection. When the animals were treated with dextran sulphate (DS) Listeriae multiplied more rapidly and death followed within a few days. When normal baby mice were infected with this organism, fatal infection occurred. In nude mice a chronic infection developed. Secondly, a rough, haemolytic strain was used to infect mice. In normal adult mice no multiplication of this strain was observed. This holds true also for DS-treated animals. In nude mice the bacteria were eliminated slowly. Normal baby mice could only be killed if the infective dose was increased. This strain was considered to be intermediate in virulence. The infection stimulated a considerable immune response in mice, although to a lesser degree than the smooth, haemolytic Listeria strain. Thirdly, a smooth, non-haemolytic strain of L. monocytogenes serovar 1/2a was used. The bacteria were rapidly eliminated in normal, in DS-treated and in nude animals. Normal baby mice did not develop fatal disease, so it was considered that this strain of L. monocytogenes serovar 1/2a was avirulent. This variant was found to be non-immunogenic. A boosting of immunity of animals by this avirulent Listeria strain was, however, found to be possible. A reasonable explanation for the rapid elimination of avirulent L. monocytogenes serovar 1/2a from mice cannot be presented at this time. Whereas it is known that the macrophage system and the T-lymphocytes play an essential role in the resistance to virulent Listeriae, there is no increased susceptibility of the avirulent bacteria to these defence mechanisms. Other bacterial properties, such as serum sensitivity and lysozyme susceptibility, are likewise considered to be unimportant.

Abstract
The avirulent strain Listeria monocytogenes (Welshimer) induced upon a single injection 4 weeks prior to challenge with Mycobacterium tuberculosis H37Rv resistance in guinea-pigs, which was manifested by a significant decrease of spleen weight and Feldman's index in immunized animals. The degree of resistance was dependent on the immunizing dose and time of administration. Repeated high doses of Listeria yielded only a low or no effect. Further increase of resistance was obtained using the BCG lipids; however, stimulation of resistance with listeria lipids was not successful and, finally, Freund's incomplete adjuvant was significantly effective in the Feldman index only. The BCG lipids, extracted with ethanol, which contained nitrogen and water-soluble substances, induced a significant resistance against M. tuberculosis infection. The chloroform-methanol BCG lipids were also effective, however, significantly less than the ethanol-extracted material. The listeria factor Ei itself or together with Freund's incomplete adjuvant possessed only low effectiveness against mycobacterial infection. However, if injected together with ethanol-extracted BCG lipids, it produced a significant degree of resistance which was higher than that induced by lipids only. The degree of resistance was comparable with the effect of living BCG strain which served as a source of isolated lipids.

Abstract
The migration inhibition technique has been used to study delayed hypersensitivity in vitro by using peritoneal exudate cells and splenic lymphocytes from mice vaccinated with viable cells of the attenuated H37Ra strain of Mycobacterium tuberculosis and from mice vaccinated with ribonucleic acid (myc RNA) preparations obtained from viable mycobacterial cells of the same strain. Inhibition of macrophage migration was noted when purified protein derivative (PPD) or viable H37Ra cells were added to peritoneal exudate cells obtained from mice immunized with viable H37Ra cells and not from mice immunized with myc RNA. Splenic lymphocyte cultures were exposed to the same antigens in vitro. Filtered supernatant fluids from these lymphocyte cultures, when added to peritoneal exudate cells obtained from nonimmunized mice, inhibited migration only when they were obtained from lymphocytes which came from mice immunized with viable H37Ra cells. Injection of PPD intravenously into vaccinated mice resulted in inhibitory supernatant fluids from splenic lymphocyte cultures only when the lymphocytes came from mice immunized with viable H37Ra cells. However, intravenous injection of either viable H37Ra cells or of myc RNA preparations into mice vaccinated with myc RNA occasionally produced inhibitory supernatant fluids when lymphocytes were obtained from these mice. On the other hand, mice vaccinated with myc RNA or viable H37Ra cell preparations were consistently and equally protected against intravenous challenge with the virulent H37Rv strain. Thus, although some evidence was obtained for a delayed type hypersensitivity in mice vaccinated with H37Ra cells or with myc RNA to ribosomal proteins or other proteins associated with the RNA preparation, no evidence of tuberculin hypersensitivity could be detected in any mice vaccinated with the myc RNA. These results argue against a role for tuberculin hypersensitivity in immunity to tuberculous infection.

Abstract
Ribosomes of strain NOR-7 of group B Neisseria meningitidis were isolated by a procedure that included treatment of the cells with sodium dodecyl sulfate, disruption in a French pressure cell, and differential centrifugation. These preparations consisted of 66% ribonucleic acid and 24% protein and sedimented as a single component with a constant of approximately 66S. When used in immunodiffusion tests with homologous rabbit antiserum, untreated ribosomes formed two precipitin lines, when treated with ribonuclease three lines, and when Pronase-digested only one distinct line. Qualitatively indistinguishable reactions were obtained with the same antiserum and ribosomes from group A meningococci, but no precipitation occurred with those of Escherichia coli. When injected into mice, group B ribosomes elicited an increase in the number of antibody-producing spleen cells demonstrable by the hemolytic plaque technique using unsensitized sheep erythrocytes. Sensitization of the erythrocytes with increasing amounts of supernatant fluid of meningococcal cultures progressively reduced the number of demonstrable plaque-forming cells. Neuraminidase treatment of the erythrocytes increased immune hemolysis, whereas Pronase digestion reduced it. Injected mice were protected against homologous and heterologous meningococcal challenge. Both hemolysis and protection-inducing activities of the ribosomes were unimpaired by ribonuclease, but were reduced by Pronase. It is concluded that the immunological response elicited by the meningococcal ribosomes does not involve the group-specific carbohydrate antigen. The immunological mechanism by which the mice are protected against meningococcal challenge remains unknown.

Abstract
Macrophages from mice infected with facultative intracellular organisms such as Listeria monocytogenes and BCG have been shown to resist infection by antigenically unrelated intracellular bacterial parasites. This study compares phagocytosis, bacterial growth inhibition, and oxidation of glucose by macrophages from normal mice, mice infected with listeria or BCG, or mice immunized with killed listeria in incomplete Freund's adjuvant. Macrophages from listeria- and BCG-infected mice ingested more listeria; 67 and 57%, respectively, had three or more cell-associated bacteria versus 22% of controls (P < 0.001). Peritoneal macrophages from listeria- and BCG-infected animals significantly (P < 0.001 covariance analysis) inhibited growth of listeria in suspension, whereas control macrophages had no such inhibitory effect. The rate of oxidation of glucose-1-(14)C was higher in macrophages from listeria- and BCG-infected mice than from either uninfected animals or those immunized with killed listeria. During phagocytosis of killed or live bacteria, or latex particles, the rate of glucose oxidation was increased (P < 0.01). These data suggest that the cellular immunity after infection by an intracellular organism is associated with an increase in metabolic activity of macrophages, namely, an increase in the rate of glucose oxidation resulting in enhancement of phagocytosis and killing.

Abstract
Physiological saline was found to be very detrimental to the viability of Listeria monocytogenes. The LD(50) value was substantially reduced when peptone was used as the suspending fluid rather than saline. Normal splenic tissue was not inhibitory to the survival of Listeria. In experimentally infected mice, L. monocytogenes survived for 8 days in the peritoneal cavity and for at least 11 days in the spleen.

Abstract
Guinea pigs were injected subcutaneously with mycobacterial ribosomal fraction incorporated in Freund's incomplete adjuvant and tested 6 and 12 weeks later by the intradermal injection of 0.5 mug (25 TU) of Purified Protein Derivative. No evidence of delayed-type hypersensitivity could be detected in these animals, although large necrotic reactions were obtained in guinea pigs sensitized with living, attenuated mycobacterial cells. Mice also were vaccinated by the intraperitoneal injection of mycobacterial ribosomal fraction or ribonucleic acid (RNA) and tested for sensitivity to tuberculin at various subsequent times. No evidence of true tuberculin hypersensitivity could be detected at any time, although what appeared to be small Arthus type reactions were seen in mice given the largest vaccinating doses. Attempts to recall tuberculin sensitivity in vaccinated mice by the intravenous injection, 4 weeks after vaccination of living cells, of either the virulent or attenuated mycobacterial strains were unsuccessful. Instead, when the virulent cells were injected, a suppression of footpad reactivity was noted in animals made sensitive to tuberculin by the previous intraperitoneal injection of viable attenuated mycobacterial cells. Both guinea pigs and mice, vaccinated as described above, were also skin tested or footpad tested, respectively, with 2 mug of the ribosomal fraction or RNA used for vaccination. No evidence of true tuberculin hypersensitivity could be obtained; instead, in guinea pig skin very small dermonecrotic areas were noted, and in mice swelling and redness of the footpad occurred to an equal extent in both vaccinated and nonvaccinated mice. The possible role of tuberculin hypersensitivity in acquired immunity to tuberculosis is discussed, and the conclusion is reached that its part, if any, is minor.

Abstract
The relationship of the dose of vaccine to the immune response was determined in CF-1 mice vaccinated intraperitoneally with viable cells of the attenuated H37Ra strain of Mycobacterium tuberculosis and in mice vaccinated with cells of the same strain killed by autoclaving at 121 C for 15 min. The results showed, in terms of increased resistance to tuberculous infection, that the immune response with both living and killed cells was dependent upon the dose of vaccine, whereas only the living cells were dependent upon the time of challenge after vaccination. The dose response curves show dramatically that viable cells, which do not multiply in vivo, are several hundred times more effective immunizing agents against tuberculous infection than are autoclaved cells. Viable 2-week-old H37Ra cells were far more immunogenic than viable 4-week-old cells. Autoclaved 2-week-old cells, however, were no more immunogenic than autoclaved 4-week-old cells. H37Ra cells killed by boiling (98 C), exposure to 65 C for 30 min, treating with 2% phenol, or by being dried with acetone also lost most of their capacity to immunize mice. The effect of adjuvant on the immune response of mice to tuberculous infection was tested by incorporating both viable and autoclaved cells in Freund's incomplete adjuvant. We found that this vehicle had little or no effect on the immunizing capacity of either viable or heat-killed mycobacterial cells. The relationship of all the findings to the specificity of the immune response to tuberculosis is discussed.

Abstract
When mice immunized with Listeria monocytogenes were given a second injection of listeria, they showed an anamnestic immune response to intravenous challenge with listeria, as measured by enumeration of the viable infecting organisms in the spleens of the infected animals. This response was independent of the effects of the challenge dose. When mice immunized with living or heat-killed attenuated mycobacterial cells were boosted with living H37Ra, there was also an accelerated response to listeria challenge. The response was greater in the mice given the primary immunization with living cells than in those immunized with heat-killed cells. The response to listeria challenge in mice immunized and boosted with mycobacteria was of less magnitude than that in the mice immunized and boosted with listeria. Growth of listeria in the mice immunized and boosted with mycobacteria was retarded only during the first 2 days of the infection, whereas the infecting listeria in mice immunized and boosted with listeria were permanently inactivated. Mice immunized with mycobacterial ribosomal fraction and restimulated with living mycobacterial cells showed no accelerated response to listeria challenge. It is evident from these results that resistance to these organisms is specifically evoked, but that once evoked it is not completely nonspecific in action. Also, the resistance produced by the mycobacterial ribosomal fraction to challenge with mycobacteria is completely specific in action. Therefore, it has been shown that there are two mechanisms involved in acquired immunity to facultative, intracellular parasites. One is nonspecific and mediated by activated macrophages. The other is specific and mediated by a mechanism as yet unknown.
