requirement of thymus (t) lymphocytes for resistance to listeriosis.spleen cells of mice infected with listeria monocytogenes were adoptively transferred to normal mice. such lymphocytes conferred resistance to a lethal challenge with listeria. hyperimmunization of the donor reduces the number of cells necessary to transfer effective immunity. such spleen cells if treated with anti-theta serum do not transfer resistance to listeria. hence, thymus (t) lymphocytes are involved in the resistance to infection with the facultative intracellular bacteria l. monocytoge ...19724623315

evaluation and standardization of an agglutination test for human listeriosis.human sera from patients with culturally confirmed listeriosis were tested for immunoglobulin m (igm) and immunoglobulin g (igg) agglutinating antibodies with trypsinized antigens of listeria monocytogenes, streptococcus faecalis, and staphylococcus aureus. the response of humans to listeria infections is mainly igm rather than igg as found in animals. the antigens prepared from l. monocytogenes serotypes 1a, 1b, 2, 4b, and 4d were evaluated for specificity with normal sera, sera from patients w ...19724626902

salmonellosis in orally infected specific pathogen-free c57b1 mice.specific pathogen-free c57b1 mice are 100 to 1,000 times as sensitive as cd-1 mice to intravenous or oral challenge by salmonella enteritidis or s. gallinarum. resistance to infection by s. pullorum was unaffected. growth of listeria monocytogenes and mycobacterium bovis (bcg) in intravenously infected c57b1 mice was similar to that seen in cd-1 mice. quantitative counts of viable s. enteritidis in the walls of the stomach, small intestine, cecum, and large intestine and in the corresponding int ...19724628955
mechanisms of pathogenesis in listeria monocytogenes infection. vi. oxidative phosphorylation in mouse liver mitochondria during experimental listeriosis.previous reports have demonstrated early changes in hepatic carbohydrate and energy metabolism in mice infected with listeria monocytogenes. this study was undertaken to further elucidate mechanisms of damage involved in these changes. female cd-1 mice were injected intraperitoneally with 10(6)l. monocytogenes a4413. at 0, 10, and 20 hr after infection, groups of mice were sacrificed and the livers were removed and pooled. oxidative phosphorylation was assayed immediately upon isolation of mitoc ...19724628957

correlation of increased metabolic activity, resistance to infection, enhanced phagocytosis, and inhibition of bacterial growth by macrophages from listeria- and bcg-infected mice.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 ...19724629124
activity of macrophage and neutrophil cellular fractions from normal and immune sheep against listeria monocytogenes.cellular immunity to listeria monocytogenes infection was studied by assaying for antibacterial activity in fractions of leukocytes collected from the peritoneal cavity, lungs, and mammary glands of immunized sheep. the cells were collected in populations that were largely either macrophages or neutrophils. mechanically disrupted cells were divided into nuclear, lysosomal, and supernatant fluid fractions and then subjected to freezing and thawing. comparison with similarly treated rabbit cells s ...19724629255

effect of anti-cord factor antibody on experimental tuberculosis in mice.either active immunization with trehalose-6, 6'-dimycolate (cord factor)-methylated bovine serum albumin complex or passive transfer of rabbit anti-cord factor serum induced in mice an enhanced resistance against infection with virulent human mycobacterium tuberculosis. this suggests that the anti-cord factor antibody exerts an infection-protecting effect by neutralizing the toxic action of cord factor during the course of living virulent infection with tubercle bacilli. the protective effect of ...19734632133

mouse splenic peroxidase and its role in bactericidal activity.spleen cell suspensions from akr and cd-1 mice contain peroxidase activity as determined by guaiacol oxidation. this activity is found predominately in the 20,000 x g pellet fraction of spleen cell homogenates. in the presence of h(2)o(2) and chloride ion at acidic ph, splenic peroxidase mediates the oxidation of d- or l-alanine to co(2), nh(3), and acetaldehyde. the same reaction mixture without added amino acid can kill both gram-positive and gram-negative bacteria. the conditions for both rea ...19724632463
recall of acquired cellular resistance in mice by antigens from killed brucella.mice infected with brucella abortus 19 were challenged intravenously with listeria monocytogenes. spleen assays to determine the number of viable listeria cells present revealed that these mice were highly resistant to listeria when challenged on day 17 of the brucella infection. resistance was absent in mice challenged on the 5th day and was declining in mice challenged on the 33rd day. resistance could not be detected by day 49 of the brucella infection but could be recalled by the injection o ...19724632467

fate of listeria monocytogenes in normal rabbit serum.viability of listeria monocytogenes suspended in either normal rabbit serum or listericidal factor is significantly reduced before cell lysis. in normal serum listeria populations are initially reduced by clumping of viable bacteria, and the cells within these clumps are morphologically altered and killed by the listericidal factor in serum. this clumping is complement independent and does not occur after suspension in purified listericidal factor. in electron micrographs, densely stained amorph ...19734633292

abolition of swarming of proteus by p-nitrophenyl glycerin: application to blood agar media.comparative plate counts were made of staphylococcus aureus and streptococcus pyogenes growing on blood agar supplemented with individual chemicals to abolish the swarming of proteus. b-phenylethanol, sodium azide, and p-nitrophenyl glycerin (pnpg) were used as anti-swarm agents. each anti-swarm agent effectively abolished swarming for 24 h, but azide failed to control swarming for longer periods of incubation. in addition, azide displayed growth inhibition towards the staphylococci and streptoc ...19734715553

cellular immunity of mice infected with listeria monocytogenes in diffusion chambers.the importance of bringing live bacteria into intimate contact with macrophages as a prerequisite for establishing cellular immunity was investigated. the bacterium listeria monocytogenes was shown to replicate and survive in diffusion chambers implanted in the peritoneal cavities of mice. humoral substances accruing from host responses to diffusing soluble antigens of the microorganism were unable to inactivate the bacteria. the resistance of mice immunized by subcutaneous inoculation of the li ...19684876129
relative susceptibility of acid-fast and non-acid-fast bacteria to ultraviolet light.mycobacterium tuberculosis strain erdman, m. bovis (bcg), and m. phlei showed a 1- to 2-log drop in viability after exposure to ultraviolet light compared to a 5-log drop over the same period for staphylococcus albus, listeria monocytogenes, escherichia coli, pseudomonas aeruginosa, salmonella enteritidis, and serratia marcescens. l. monocytogenes showed an initial resistance to ultraviolet inactivation, but later the inactivation rate increased sharply. the significance of these findings with r ...19714928599

mechanisms of acquired resistance in mouse typhoid.experiments in vitro comparing normal mouse peritoneal macrophages with cells from salmonella typhimurium-infected mice have shown that the "immune" macrophages have conspicuously enhanced microbicidal properties. whereas normal macrophages could inactivate only 50 to 60% of intracellular s. typhimurium pretreated with immune serum, cells from infected animals killed virtually all ingested organisms and did so at an accelerated rate. macrophages from listeria monocytogenes-infected mice were sho ...19664958757
