| immunologic consequences of antibiotic-induced abridgement of bacterial infection: effect on generation and loss of protective t cells and level of immunologic memory. | ampicillin was employed in mice to determine the effect of rapidly abridging bacterial infection on the generation of t cell-mediated antibacterial immunity. it was found that antibiotic-induced abridgement of infection with listeria monocytogenes had a pronounced effect on the generation of splenic t cells capable of adoptively immunizing normal recipients against a listeria challenge infection. ampicillin given at the time of maximum bacterial growth at 24 hr caused a striking reduction in the ... | 1981 | 6787128 |

| effect of csf on bacterial growth. | the growth patterns of five potentially pathogenic bacteria (staphylococcus aureus, escherichia coli, listeria monocytogenes, group b beta-hemolytic streptococcus, and klebsiella pneumoniae) and a commonly encountered, nonpathogenic microorganism (s epidermidis) were compared using csf, trypticase soy broth (tsb), and a phosphate buffer. each grew less in csf than in tsb. escherichia coli was least affected with a median difference of 2 logarithms between csf and tsb at 24 hours of growth, where ... | 1981 | 6779784 |
| resistance to mycobacterium tuberculosis h37rv infection induced by listeria and mycobacterial lipids. | 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 l ... | 1981 | 6781995 |
| [listeriosis in the adult: report of 7 cases]. | human beings are frequently exposed to listeria monocytogenes, but these microorganisms are rarely pathogenic for healthy subjects. in recent years an increase in the frequency of listeriosis has been reported, especially in patients with severe underlying diseases. in the present work the clinical, microbiological, therapeutic and prognostic characteristics of seven adult cases of listeriosis are reviewed. l. monocytogenes was isolated from blood, cerebrospinal fluid or both. most patients had ... | 1981 | 6782395 |

| increased resistance and depressed delayed-type hypersensitivity to listeria monocytogenes induced by pretreatment with lipopolysaccharide. | intravenous injection of a small dose of lipopolysaccharide 24 h before infection with listeria monocytogenes enhanced the resistance of mice to this organism. this protective effect of lipopolysaccharide related to the ability of nonimmune macrophages to inhibit bacterial proliferation in livers and spleens. surprisingly, lipopolysaccharide-treated mice exhibited inferior acquired immunity, as measured by adoptive transfer of immunity to normal mice, delayed-type hypersensitivity to listeria an ... | 1981 | 6783542 |
| pathogenesis of listeria monocytogenes for gnotobiotic rats. | listeria monocytogenes colonized the gastrointestinal tract of adult germfree rats (10(10) to 10(11)/g, dry weight) within 24 h after oral exposure. between 3 and 14 days after monoassociation, l. monocytogenes caused a self-limiting pseudomembranous colitis, bacteremia, and infection of the spleen and liver. monoassociation of rats with listeria for 8 weeks stimulated 32- and 4-fold increases in serum immunoglobulin a (iga) and igg, respectively, whereas serum igm decreased 2-fold. the normal m ... | 1981 | 6783550 |
| esculin hydrolysis by gram positive bacteria. a rapid test and it's comparison with other methods. | a number of bacteria hydrolyze esculin enzymatically to esculetin. this characteristic is used by taxonomists and clinical microbiologists in the differentiation and identification of bacteria, especially to distinguish lance-field group d streptococci from non-group d organisms and listeria monocytogenes from morphologically similar erysipelothrix rhusipoathiae and diphtheroids. conventional methods used for esculin hydrolysis require 4--48 h for completion. we developed and evaluated a medium ... | 1981 | 6783825 |
| [enzyme-immuno-assay in listeriosis: detection of antibody and antigen (author's transl)]. | an enzyme-immuno-assay (eia) was developed for the determination of antibodies to listeria monocytogenes o- and h-antigens of serotypes 1 and 4b, which are predominant in the federal republic of germany. the results correlated well with the tube agglutination but the titers in eia were considerably higher. thus one advantage of eia was its sensitivity. in addition, the eia offers the possibility to detect antibodies belonging to different immunoglobulin classes. the eia is easy to perform and re ... | 1981 | 6784391 |
| antibacterial peptide from normal rat serum. 1. isolation from whole serum, activity, and microbicidal spectrum. | a procedure is described for purification of the primary bactericidal component of normal rabbit serum active in vitro against bacillus subtilis. a 65 000-fold increase in specific bactericidal activity per milligram of serum protein was obtained, yielding a low molecular weight, heat-stable polypeptide fraction (pc-iii) exhibiting biological activity at protein concentrations below 10 ng/ml. this preparation appeared homogeneous as judged by column chromatography and analytical nadodso4-polyacr ... | 1981 | 6796108 |
| comparative effects of carrageenan on systemic candidiasis and listeriosis in mice. | carrageenan, a toxic substance for the mononuclear phagocyte system (mps), increase drastically the susceptibility of mice against listeria monocytogenes challenge but induces concurrently an increasing resistance against systemic candidiasis and granulocytosis. these results corroborate the minor role played by mps and suggest that polymorphonuclear cells play a major role in non-specific resistance of mice against systemic candidiasis. | 1981 | 6796313 |

| antigen-presenting function of alveolar macrophages: uptake and presentation of listeria monocytogenes. | mouse alveolar macrophages were characterized and compared to resident peritoneal macrophages for their ability to take up and present to immune t cells the bacteria listeria monocytogenes. both macrophage populations contained a similar proportion of ia-positive macrophages (approximately 5%). however, alveolar macrophages showed a deficiency in the uptake of listeria monocytogenes. macrophage, antigen-presenting function was studied by measuring the proliferative response of listeria-immune t ... | 1981 | 6778924 |
| delayed hypersensitivity reactions to listeria monocytogenes in rats decomplemented with cobra factor and in c5-deficient mice. | the in vivo effect of cobra factor (cof), the complement-activating protein of cobra (naja naja) venom, was investigated, using quantifiable assays for localization of labelled donor lymphoblasts and of host macrophages in intraperitoneal and subcutaneous sites of injection of antigens from listeria monocytogenes. both commercially available (cordis) and highly purified cof impaired these inflammatory responses, suggesting that the complement-activating protein was itself responsible rather than ... | 1981 | 6788681 |
| effects of dimethyldioctadecylammonium bromide on phagocytosis and digestion of listeria monocytogenes by mouse peritoneal macrophages. | listeria monocytogenes was labelled with [3h]-thymidine and phagocytosis in vivo, measured after the intraperitoneal injection of killed or viable listeria. the loss of intracellular radioactivity after incubation in vitro was used as a measure for digestion. killing was assessed by counting the numbers of viable listeria before and after in vitro incubation. peritoneal macrophages from mice immunized with viable listeria showed better phagocytosis and digestion of both killed and viable listeri ... | 1981 | 6788683 |
| aging and cellular defense mechanisms: age-related changes in resistance of mice to listeria monocytogenes. | age-related changes in resistance of mice to infection with listeria monocytogenes were investigated. one-month-old mice exhibited the least resistance, and the resistance level increased over the first few months to reach a maximum by 8 months. increase in age thereafter was accompanied by a slow but progressive decrease in resistance. thus, 50% lethal doses for 1-, 8-, and 24-month-old mice were 10(4.2), 10(6.6), and 10(5.2), respectively. in spite of differences in resistance, the growth of l ... | 1981 | 6788698 |

| studies on glutamic acid decarboxylase from listeria monocytogenes. | the isolation and characterization of glutamic acid decarboxylase from listeria monocytogenes has been described. effects of various concentrations of glutamic acid as a substrate and pyridoxal phosphate as coenzyme on the activity of the partially purified enzyme have been examined and their km and vmax values determined. the enzyme exhibits relatively higher activity in 0.1 m pyridine-pyridine hydrochloride buffer with a ph value of 4.6. | 1981 | 6790145 |
| interaction of rat platelets with listeria monocytogenes. | listeria monocytogenes induced aggregation of rat platelets in vitro and stimulated the nonlytic release of [3h]serotonin. listeria-induced platelet aggregation and serotonin release required the presence of intact listeria, was maximal at a 1:1 listeria/platelet ratio, required a plasma cofactor, and was not inhibited by indomethacin, acetylsalicylic acid, or apyrase. aggregation either of platelets in platelet-rich plasma with adenosine diphosphate or of washed platelets with thrombin resulted ... | 1981 | 6790437 |
| fate of listeria monocytogenes in resident and activated macrophages. | a sensitive and highly reproducible assay was utilized to study in vitro interactions of listeria monocytogenes with resident and activated macrophages. the technique is not compromised by extracellular events and can readily differentiate between the efficiency of ingestion and the postphagocytic fate of bacteria. heat-labile factors in human or homologous serum markedly enhanced the phagocytosis of listeria without noticeably affecting the intracellular fate of the microorganisms. the behavior ... | 1981 | 6790438 |
| a genetic locus responsible for salmonella susceptibility in bsvs mice is not responsible for the limited t-dependent immune responsiveness of bsvs mice. | bsvs mice are known to be highly susceptible to salmonella infection. we have shown that the bulk of the difference in susceptibility between bsvs and salmonella-resistant a/j mice is the result of a genetic difference at a single locus not closely linked to h-2, igh-c, or hbb, and not x-linked. we have backcrossed the a/j allele at this locus into bsvs mice for 8 successive generations and have demonstrated that the salmonella resistance afforded by this allele is not the result of a restoratio ... | 1981 | 6790621 |
| meningitis and bacteraemia due to listeria monocytogenes in compromised hosts. | the clinical history of 3 adult patients infected by listeria monocytogenes is presented. one patient with chronic lymphatic leukaemia developed purulent meningitis; the 2 others had chronic renal failure and were undergoing routine haemodialysis. of the latter, one developed meningitis and the other bacteraemia after receiving 2 blood transfusions. immuno-suppression, or the underlying disease of the hosts, probably played a role in permitting the infection to establish itself. the rural enviro ... | 1981 | 6791149 |

| purification and further characterization of phenol extract from listeria monocytogenes. | a phenol-water extract of listeria monocytogenes virulent strains 9-125 (serotype 4b) was purified by 3 cycles of ultracentrifugation. the purified extract reacted positively in limulus amoebocyte lysate assay at a concentration of 1 microgram/ml. this value was 1,000 times higher than that for salmonella abortus equi lipopolysaccharide. the phenol extract was toxic to chicken embryos (median lethal dose was 40.5 micrograms) and contained carbohydrates (heptose, hexose, hexosamine, methylpentose ... | 1981 | 6791538 |
| killing of listeria monocytogens by conventional and germfree rat sera. | serum from both germfree and conventional rats, but not plasma or plasma serum, killed listeria monocytogenes in vitro by a calcium-dependent mechanism that was independent of either complement or lysozyme and was not inhibited by the addition of iron. the listericidin was purified by passing either rat serum or platelet lysate through a nitrocellulose filter (0.2 micrometer) and eluting the activity from the filter with 0.02 n hcl. the partially purified listericidin was heat stable (56 degrees ... | 1981 | 6792076 |
| mechanism for nonspecific immunity of listeria monocytogenes in rats mediated by platelets and the clotting system. | a proposed mechanism for nonspecific immunity to listeria monocytogenes in rats based on the existence of an activatable lysin is described. using a deoxyribonucleic acid release assay, we found lysin activity in serum made from whole blood but not in serum made from platelet-free plasma. washed platelets and platelet lysates exhibited only partial activity as compared with that in serum. this activity was amplified by the addition of platelet-free plasma serum. the activity of the lysin was una ... | 1981 | 6792078 |

| development of a simple passive haemagglutination-inhibition assay for listeria monocytogenes lipoteichoic acid. | a simple assay for listeria lipoteichoic acid was devised. it is based on the property of this substance to attach spontaneously to erythrocytes. thus coated rabbit erythrocytes were agglutinated by a rabbit antiserum raised towards dead listeria. inhibition of this passive agglutination was used as a measure of listeria lipoteichoic acid. cross-reactivity of lipoteichoic acid from lactobacillus fermenti in the assay and inhibition by simple sugars suggest that the assay is specific for terminal ... | 1981 | 6792287 |
| aging and antimicrobial immunity. impaired production of mediator t cells as a basis for the decreased resistance of senescent mice to listeriosis. | immunity to infection of mice with the facultative, intracellular pathogen listeria monocytogenes was employed as a model system to investigate the immunological basis for the age-associated decline in anti-microbial immunity. in response to a sublethal immunizing infection, aged (24-mo old or more) mice displayed a smaller increase in spleen weight, spleen cellularity, and splenic t cell content than young (3- to 4-mo-old) mice. aged mice also generated a smaller number of anti-listeria protect ... | 1981 | 6792317 |
| concanavalin a-induced resistance to listeria monocytogenes and activation of macrophages: defect in mice treated with 89sr. | 89sr-treated mice injected with concanavalin a (con a) 24 h prior to infection with listeria monocytogenes (lm) could not enhance the clearance of lm from the spleen. adoptive transfer of normal syngeneic spleen cells together with con a rendered these animals more resistant. spleen cells of 89sr-treated or age-matched control mice were stimulated with con a for 24 h, and supernatant fluids were assessed for macrophage-activating factor (maf), i.e. the ability to activate resident peritoneal mac ... | 1981 | 6793374 |
| modification of protective mechanisms against listeria monocytogenes during pregnancy. | protective mechanisms against listeria monocytogenes were examined at different stages of pregnancy in c3h/he mice. bacterial growth at an early phase of infection was depressed from day 10 of gestation to day 5 postpartum, whereas bacterial growth at a late phase of infection was enhanced on day 10 of gestation. spleen cells from nonimmunized mice on day 10 of gestation suppressed the expression of acquired resistance to infection in immunized mice. we conclude that the augmented resistance dur ... | 1981 | 6793730 |
| susceptibility of enterococci and listeria monocytogenes to n-formimidoyl thienamycin alone and in combination with an aminoglycoside. | the susceptibilities of 12 strains of enterococci and 10 stains of listeria monocytogenes to n-formimidoyl thienamycin were determined by a standard broth dilution method. minimal inhibitory concentrations for l. monocytogenes strains were less than 0.25 micrograms/ml. as a group, strains of streptococcus faecium were less susceptible than streptococcus faecalis strains, but even for the latter, the minimal inhibitory concentrations were slightly greater than those previously reported. minimal b ... | 1981 | 6794445 |
| [antigens common to human malignant tumors and certain species of microorganisms]. | agglutination, gel precipitation and immunoelectrophoresis demonstrated the presence of antigens common for human malignant tumors of different sites and bcg and listeria monocytogenic microorganisms. the radioimmunoassay of sera in the agglutination test showed that these sera reacted with tumor cells rather than with cells from normal human tissues. the common antigen had the electrophorectic mobility in the beta-globulin zone. | 1981 | 6794672 |

| interactions of killed listeria monocytogenes with the mouse complement system. | incubation of mouse serum with listeria monocytogenes involved activation of the alternative complement pathway, resulting in depletion of both classical and alternative pathway activity. the activation process gave rise to reactive (calcium- and magnesium-independent) lysis of, specifically, rabbit erythrocytes, which become resistant to this form of hemolysis by sensitization with antibodies. the possible implications of these findings for l. monocytogenes as an intracellular parasite and for ... | 1981 | 6795123 |
| dissociation of bactericidal activity from other functions of activated macrophages in exudates induced by thioglycolate medium. | macrophages displayed increased spreading, increased fc-receptor-mediated phagocytosis, and increased secretion of plasminogen activator when collected from the peritoneal cavities of either listeria-immune mice challenged intraperitoneally 3 days earlier with listeria or nonimmune mice injected intraperitoneally 3 days earlier with fluid thioglycolate medium. in contrast, macrophages from the thioglycolate-induced peritoneal exudates were severely impaired in vitro in their ability to destroy l ... | 1981 | 6795125 |
| natural killer activity in the peritoneal exudates of mice infected with listeria monocytogenes: characterization of the natural killer cells by using a monoclonal rat anti-murine macrophage antibody (m1/70). | exudates induced by i.p. injection of five listeria monocytogenes (lm) constituted a rich source of cba/j murine natural killer (nk) cells. maximum expression of nk activity was seen from day 2 through day 6 after initial exposure to lm. when nylon wool nonadherent peritoneal exudate cells were examined by a single-cell cytotoxicity assay, the number of cells binding to yac-1 target cells increased after infection as did their individual lytic capacity. a monoclonal rat anti-murine macrophage an ... | 1981 | 6795262 |
| identification of a macrophage antigen-processing event required for i-region-restricted antigen presentation to t lymphocytes. | the mechanism of macrophage-antigen handling was studied using a system that involves the quantitation of the antigen-specific binding of listeria monocytogenes-immune t cells to macrophages. specific t cells did not bind to native antigen. because the specific binding of t cells to macrophages could be measured during a short (5- to 15-min) interaction, it was possible to follow the temporal development of a t cell-binding substrate with increasing time of antigen-macrophage interaction. in con ... | 1981 | 6795263 |
| t cell-mediated cytotoxicity induced by listeria monocytogenes. iii. phenotypic characteristics of mediator t cells. | cytotoxic thymus-derived lymphocytes (ctl) generated in vitro by restimulating rat cells with listeria antigen- (lma) pulsed syngeneic accessory cells were characterized in respect to their surface membrane markers. lm-dependent ctl were devoid of detectable surface immunoglobulin (ig) and receptors for the fc region of rabbit igg. experiments with monoclonal antibodies to rat t cell markers revealed that these cytotoxic cells have the phenotypic profile w3/13+, w3/25-, mrc ox 8+. lm-dependent c ... | 1981 | 6795271 |
| generation of alloreactive cytotoxic t lymphocytes: production of t cell and macrophage helper factors in addition to il 1 and il 2 by peritoneal cells from mice immunized to listeria monocytogenes. | we investigate the production and biological activity of soluble helper factors produced by peritoneal t cells and macrophage derived from mice primed in vivo with listeria monocytogenes. supernatant fluids from co-cultures of these immune t cells and activated macrophages contained interleukin 1 (il 1) and interleukin 2 (il 2), and had the ability to assist the generation of cytotoxic t lymphocytes (ctl) from a population of nylon wool nonadherent spleen cells sensitized to allogeneic heat-trea ... | 1981 | 6795272 |
| genetic control of cell-mediated immunity in the rat. i. transfer of dth to bacterial antigens is restricted by the b region of rt1. | the genetic basis of allogeneic restriction in the transfer of delayed type hypersensitivity (dth) to soluble listeria monocytogenes antigens (lma) in rats was analysed using a set of congenic strains. the dth parameter assayed was the localization of radiolabelled donor lymphoblasts in subcutaneous antigen stimulation sites in the ear. sharing of the rt1,b region between the donor and host was essential for the transfer of dth to lma, which suggests that the rt12.b region codes for restriction ... | 1981 | 6795278 |
| effects of lactobacilli on parameters of non-specific resistance of mice. | the viability of lactobacillus plantarum in vivo and the effects of viable and heat-killed lactobacilli on parameters of non-specific resistance were studied. after intravenous administration of 10(8) viable lactobacilli, which is a dose with optimal adjuvant activity, viable lactobacilli could be isolated from spleens for more than 1 week and from livers and lungs for more than 3 weeks. both viable and heat-killed lactabacilli stimulated the clearance of colloidal carbon, viable bacteria stimul ... | 1981 | 6795431 |
| efficacy of ampicillin therapy in experimental listeriosis in mice with impaired t-cell-mediated immune response. | the importance of intact host defense mechanisms for successful antimicrobial therapy was investigated via a comparison of the activities of ampicillin against experimental listeria monocytogenes infections in normal mice and congenitally athymic (nude) mice. nude mice were used for these experiments because recovery from infection with this organism depends on development of cellular immunity induced specifically by a t-cell-mediated reaction. when infections ampicillin per mouse (32 doses of 2 ... | 1981 | 6972727 |

| suppression of antibacterial immunity by infection with influenza virus. | the effect of influenza virus infection on systemic antibacterial resistance was assessed in a mouse model. prior infection with influenza virus by the intranasal route led to a reduced level of macrophage activation in response to intravenous challenge with listeria monocytogenes. specific immunity to listeria was measured using adoptive transfer of immune spleen cells. preinfection of recipient mice with influenza virus reduced the level of adoptive immunity. influenza virus preinfection of im ... | 1981 | 6974206 |
| immunological memory to listeria monocytogenes in rodents. iv. studies on origin and fate of tissue-positioned t memory cells. | in this report on memory t cells mediating anti-microbial resistance to listeria monocytogenes (lm) it was analysed whether memory cells found in tissue during late-phase (e.g. 10-60 days after infection) are long-lived progeny of cells which settled in tissues during early phase (e.g. 4-10 days after infection), or whether they are short lived but constantly replaced from other sources of memory cells. the study provides evidence for both mechanisms. transfer and parabiosis experiments as well ... | 1981 | 6976311 |
