| stimulation of cell-mediated resistance in mice to infection with listeria monocytogenes by vitamin a. | vitamin a given as retinol-acetate, retinol-palmitate as well as the derivates retinoic acid and a retinoid, strongly fortified the resistance of mice to infection with virulent cells of listeria monocytogenes. however, strong enhancement of resistance was only achieved when high toxic doses of vitamin a were given. apparently, this effect was due to a stimulation of the function of the mononuclear phagocytic system rather than of the t lymphocyte. | 1979 | 115378 |
| long-term culture of canine peripheral blood monocytes in vitro. | various cultural conditions were assessed for their ability to maintain canine peripheral blood monocytes in vitro. approximately ten days after incubation of peripheral blood leukocytes in earle's minimum essential medium supplemented with homologous red cell lysates and normal horse serum, virtually a pure macrophage culture was obtained which could then be maintained for about two months. this culture was judged to be pure by surface marker analysis and their phagocytic activity. the number o ... | 1979 | 115559 |
| purification of a surface-specific soluble antigen from listeria monocytogenes. | a complex antigenic preparation obtained from listeria monocytogenes serovariant 4b by freeze-pressing, centrifugation, and gel filtration treatment was studied by crossed immunoelectrophoresis, with the aim of preparing an antigenic fraction that could be used to investigate the serological response to listeric infection. of 17 immunoprecipitates revealed in the soluble extract, one of three major antigens (designated antigen 2) was shown to be a strong antigen in humans or rabbits infected wit ... | 1979 | 115793 |
| response to therapy in an experimental rabbit model of meningitis due to listeria monocytogenes. | a uniformly fatal, reproducible model of experimental meningitis due to listeria monocytogenes was developed in rabbits for study of the natural progression of the disease and was used to evaluate treatment regimens. bacterial titers in cerebrospinal fluid and pleocytosis approximated those found in humans. therapeutic studies in vivo revealed that rifampin was less rapidly bactericidal than ampicillin or penicillin, the agents usually recommended for treatment of meningitis; that penicillin plu ... | 1979 | 115932 |
| the specific binding of listeria monocytogenes-immune t lymphocytes to macrophages. i. quantitation and role of h-2 gene products. | a system was developed to study the binding of listeria monocytogenes-specific t cells to l. monocytogenes-pulsed macrophages as an analogue of the initial phase of t-cell activation: antigen recognition. specific binding, demonstrable after a brief (1 h) contact, was quantitated by the depletion of l. monocytogenes-specific t-cell activity in the cells nonadherent to l. monocytogenes-pulsed macrophage monolayers. l. monocytogenes-specific t-cell function was measured by its ability to activate ... | 1979 | 115958 |

| age-related defense against infection with intracellular pathogens. | young adult (6--12 weeks old) and aged (20--24 months old) nmri mice were infected with various intracellular parasites. the following results were obtained: (1) after a sublethal infection with listeria monocytogenes, aged mice were found to show a resistance similar to that of young adults. a challenge infection with this pathogen was followed by specific immunity of long duration in both age-groups. (2) on the other hand, young animals were significantly more resistant to salmonella typhimuri ... | 1979 | 116909 |
| specific lyt 123 cells are involved in protection against listeria monocytogenes and in delayed-type hypersensitivity to listerial antigens. | specific anti-lyt antisera and complement were used to determine the lyt phenotype of peritoneal exudate t lymphocytes from listeria monocytogenes-immune mice. it was found that lyt 123+ t cells are crucially involved both in protection against listerial infection and in delayed-type hypersensitivity (dth) to listerial antigens. thus, both functions critically depend on a t-cell subclass phenotypically different from that which mediates dth to noninfectious antigens and help in antibody formatio ... | 1979 | 117073 |

| listeria monocytogens: synergistic effects of ampicillin and gentamicin. | listeria monocytogenes infections are most common in newborn infants and persons with impaired defense mechanisms. there are reports of successful treatment with ampicillin alone: however, there is uncertainty as to what regimen constitutes the most effective therapy. the purpose of this study was to illustrate the in-vitro synergism between ampicillin and gentamicin against l. monocytogenes. seven strains of l. monocytogenes isolated from bloods or cerebrospinal fluids of infants and three cont ... | 1979 | 117697 |
| [listeria enzootic in newborn lambs]. | epizootological, clinical and pathomorphological studies were made of a meningo-encephalitic form of listeriotic enzooty in new born lambs. the clinical symptoms as well as the patho-anatomical and patho-histological changes in the brain and in the inner organs of dead lambs were described. arisal of enzooty was connected with the inclusion of silage in the daily ration of ewes. it was assumed also that infection of suckling lambs possible by the milk of diseased mother-ewes also and in the pren ... | 1979 | 118579 |
| differing contribution of polymorphonuclear cells and macrophages to protection of mice against listeria monocytogenes and pseudomonas aeruginosa. | bacterial growth and lethality of listeria monocytogenes in mice were augmented by carrageenan-treatment and x-irradiation (8 j kg-1), whereas growth and lethality of pseudomonas aeruginosa were augmented by x-irradiation but not by carrageenan-treatment. protection against l. monocytogenes, at least in the early phases, appears to depend mainly on macrophages, since carrageenan depletes macrophages but not polymorphonuclear cells (pmn), whereas protection against p. aeruginosa appears to depend ... | 1979 | 119029 |
| [bacteriophage typing of 823 "listeria monocytogenes" strains isolated in france from 1958 to 1978 (author's transl)]. | this study was undertaken to establish a typing scheme for listeria monocytogenes. a total of 823 strains, isolated in france from 1958 to 1978, were studied; 69.4% of these belonged to serotype 4. using a set of 20 phages, the lytic activity, frequency and specific character of these phages were estimated and phage typing carried out. we were able to define a phage typing system for l. monocytogenes using 12 principal phages and 3 secondary phages. in order to discriminate phages types within s ... | 1979 | 119457 |

| influence of lipids from listeria monocytogenes on the course of infections due to some gram-positive bacteria in mice. | the influence of lipids from listeria monocytogenes on the course of infections due to some gram-positive cocci streptococcus pyogenes, streptococcus faecalis and staphylococcus aureus and l. monocytogenes was studied in white mice. varying doses of the lipid preparation were administered before infection. mortality of the animals and rate of elimination of the bacteria from the organs and blood circulation were recorded. in appropriate doses, the lipids markedly enhanced resistance to the afore ... | 1979 | 121229 |
| [increased catabolism of antigen and enhanced recruitment of antigen-sensitive cells by activation of macrophages with a bacterial phospholipid extract (ebp) (author's transl)]. | intravenous (iv) infection of a bacterial phospholipid extract (ebp) 24 h before iv immunization of mice with sheep red blood cells has modified the specific immune response. a decrease of the response evaluated by the number of rosette-forming cells was observed after the larger doses of ebp. this effect appeared secondarily to an increased catabolism of antigen. infection of a medium sized dose of ebp directly into the portal vein induced a decreased response by enhancing antigen phogocytosis ... | 1979 | 121519 |
| [meningoencephalitis caused by listeria monocytogenes in adults. description of 2 cases]. | two patients are presented who had listeria meningo-encephalitis. they were both adults and reduced in defences against infections. the diagnosis was made by isolation of listeria monocytogenes from cerebrospinal fluid cultures. one of the patients recovered; other died although therapeutic measures were promptly started. the authors suggest the need for a careful research about listeria infections in our country. | 1979 | 121687 |
| protection of mice against babesia microti with cord factor, coam, zymosan, glucan, salmonella and listeria. | cord factor (trehalose 6-6' dimycolate). coam (chlorite-oxidized oxyamylose), zymosan, glucan, salmonella enteritidis 11rx and listeria monocytogenes were found to protect mice against subsequent infection with babesia microti, an intra-erythrocytic protozoan parasite. this protection was not observed after injection of staphylococcus epidermidis, a viridans group streptococcus, thioglycollate, or colloidal carbon. all the agents which protect against b. microti have also been reported to induce ... | 1979 | 121772 |

| effect of tilorone treatment on intracellular microbial infections in specific-pathogen-free mice. | specific-pathogen-free cd-1 mice were treated orally with the drug tilorone (2,7-bis[2-diethylaminoethoxy]fluoren-9-one hydrochloride) at dosages of 10 or 100 mg per kg of body weight. drug was given 24 h before challenge and then every other day for up to 15 days. growth of sublethal doses of listeria monocytogenes, mycobacterium bovis (bcg montreal), m. tuberculosis h37rv, and salmonella enteritidis in the livers and spleens of intravenously challenged mice was significantly increased compared ... | 1975 | 125066 |
| effect of oral niridazole treatment on some bacterial infections in mice. | treatment of specific-pathogen-free cd-1 mice with oral doses of 10 or 100 mg of niridazole per kg of body weight given 24 h before challenge and then every other day for up to 15 days altered the growth curves for listeria monocytogenes, mycobacterium bovis (bcg montreal), m. tuberculosis h37rv, and salmonella enteritidis seen in the livers and spleens of the treated animals. niridazole in an oral dosage of 10 mg/kg reduced (but did not eliminate) tuberculin hypersensitivity in the mycobacteria ... | 1975 | 125067 |
| [effect of attenuated listeria monocytogenes cultures on the development of a sarcoma graft, mouse mammary epitheliomas and a dog carcinoma]. | the injection of attenuated listeria monocytogenes culture together with bp8 sarcoma cells into c3h mice prevented the taking of the graft. moreover, the intratumoral injection of attenuated listeria doubled the survival time of the animals and, in one case a regression of the tumour was observed. after intratumoral injection, in three out of five mice, the mammary carcinoma disappeared, and the course of a gingival carcinoma in a dog was slowed down. | 1975 | 126749 |

| antitumor activity of bacterial infection. ii. effect of listeria monocytogenes on growth of a guinea pig hepatoma. | growth of a guinea pig hepatoma was suppressed when tumor cells were mixed with viable listeria monocytogenes (lm) before intradermal (id) injection into syngeneic recipients. heat-killed lm were less effective than viable organisms in suppressing tumor growth. a vaccine containing oil droplets and lm cell walls lacked antitumor activity. intratumor injection of viable lm on the 7th day after id injection of tumor cells prolonged survival of guinea pigs that did not succumb to lm infection. afte ... | 1975 | 164568 |
| [ultrastructure of l-forms. ii. l-forms of listeria monocytogenes]. | a study was made of ultrathin sections of the stable l-forms of listeria obtained under the action of penicillin in meat-peptone-liver broth. a marked cellular polymorphism was found in the l-form culture: within the same colony cells differed in size, shape and fine structure. it is supposed that polymorphism could be partially explained by a different plasticity and premeability of cytoplasmic membrane in different types of cells of the same l-colony. the three-layer structure of the membrane ... | 1975 | 164746 |
| specific immunity and nonspecific resistance to infection: listeria, protozoa, and viruses in mice and hamsters,. | specific immunity developed by mice against protozoan (toxoplasma gondii and besnoitia jellisoni) and bacterial (listeria monocytogenes) infections was compared with nonspecific protection conferred by prior infections. the results indicated that homologous immunity protected mice from more than 10-5 ld50 of t. gondii or b. jellisoni, but from only 10-2 ld50 of l. monocytogenes. heterospecific protection among these organisms was for 10-0.4 minus 10-1.2 ld50. in studies in hamsters specific immu ... | 1975 | 165241 |
| the effects of protein deprivation on cell-mediated immunity. | the effect of protein insufficiency on immune responsiveness was investigated in inbred mice fed isocaloric diets low and normal in protein. mice were tested for aberrations of cell-mediated and humoral immunities. protein insufficiency enhances cell-mediated immunity while depressing or not affecting humoral immunity. cell-mediated immunity was enhanced in testing: allogeneic skin graft rejection, spleen cell responsiveness to phytohemagglutinin, the graft-vs-host reaction, macrophage function, ... | 1975 | 167880 |

| listeria monocytogenes endophthalmitis. | a 62-year-old white man developed an acute anterior chamber inflammation in his left eye. listeria monocytogenes was cultured from the vitreous aspirate. there was no evidence for ocular trauma or distant site of infection from which hematogenous spread of the organism occurred. no underlying state of immunocompromise was demonstrated. the endophthalmitis responded well to therapy. | 1977 | 302649 |
| resistance and susceptibility of mice to bacterial infection: genetics of listeriosis. | a survey of various strains of mice showed distinct differences in resistance or susceptibility to listeria monocytogenes. c57b1, related sublines, nzb, and sjl were resistant to listeria, whereas balb/c, cba, a, dba/1, c3h, lp.riii, 129, and wb were susceptible. the gene(s) responsible for resistance and susceptibility to listeria were studied in detail. c57bl6/6, b10.d2, and b10.a mice were 100 times more resistant than were balb/c, cba, and a. resistance of the (c57b1/6 x balb/c)f1 was interm ... | 1978 | 305895 |
| transfer of immunity against listeria monocytogenes by t cells purified by a positive selection technique. | affinity columns prepared with rabbit antibody to the f(ab')(2) fragment of rat immunoglobulin were used to separate rat thoracic duct lymphocytes into sub-populations that differ with respect to the density of their surface membrane immunoglobulin. using this technique, it was shown that lymphocytes in the dna synthetic (s) phase of the mitotic cycle are added in increased number to the lymph of rats infected with listeria monocytogenes. the great majority of these s-phase cells lacked a high d ... | 1978 | 310423 |
| role of complement in the expression of delayed-type hypersensitivity in rats: studies with cobra venom factor. | the hypothesis was tested that delayed-type hypersensitivity (dth) to the complement-activating bacterium listeria monocytogenes is initiated by complement-derived mediators that attract sensitized lymphocytes to reaction sites. to this end dth and acquired resistance to l. monocytogenes were measured in rats injected with cobra venom factor, a potent inactivator of c3. treatment with cobra venom factor reduced the hemolytic power of serum to less than 0.5% of the control value. such decomplemen ... | 1979 | 313366 |
| effects of cannabinoids on host resistance to listeria monocytogenes and herpes simplex virus. | previous investigations from our laboratories have demonstrated that cannabinoids possess immunosuppressive properties. the present studies were designed to determine whether these agents decrease host resistance to infections with listeria monocytogenes and herpes simplex virus type 2. host resistance was measured by changes in the 50% lethal dose of the pathogen in cannabinoid-treated and control mice. the effect of cannabinoids on resistance to l. monocytogens was dose dependent. delta-9-tetr ... | 1979 | 313368 |

| antimicrobial spectrum, pharmacology and therapeutic use of antibiotics. part 2: penicillins. | the mechanism of action, resistance, antibacterial spectrum, clinical pharmacology, adverse effects, and therapeutic and prophylactic use of penicillins are reviewed. the choice of a penicillin is discussed. the only indication for the penicillinase-resistant penicillins is the suspected or demonstrated presence of staphylococcus aureus. there are no important differences in therapeutic effect among oxacillin, cloxacillin, dicloxacillin or flucloxacillin by the oral route, or among oxacillin, di ... | 1977 | 318800 |
| infection in infants and children. | infection with listeria monocytogenes is demonstrated over a 141/2 year period in 24 newborns, three infants 1 to 2 months of age, and two children. comparison of the 22 cases of listeria meningitis in newborns with 118 cases of neonatal meningitis due to other bacteria indicates a later onset of symptoms in cases of listeria meningitis with a more favorable outcome than with most other agents. treatment with ampicillin sodium appears effective. monocytic cell increases in peripheral blood or cs ... | 1977 | 322473 |
| corynebacterium equi infection complicating neoplastic disease. | corynebacterium equi, a soil-residing diphtheroid pathogenic in horses, swine and cows, caused pulmonary infection with bacteremia in two patients with lymphomas. both patients were being treated with immunosuppressive therapy, as were the patients in three previously reported human cases. unless certain characteristics of these organisms are recognized, they may be regarded as normal flora or contaminating diphtheroids. they could also be mistaken for other gram-positive rods, such as bacillus ... | 1977 | 326031 |
| listeria infection in transplant patients. five cases and a review of the literature. | we report five cases of listeria monocytogenes infection in renal transplant patients at the university of minnesota and compare them to 15 additional patients reported on in the united states literature. all patients were noted to have fever, malaise, and nonspecific symptoms of infection. there were no consistent diagnostic laboratory findings except for positive bacteriologic studies. successful treatment consisted of intravenous penicillin g potassium in most cases (ampicillin sodium was req ... | 1978 | 339878 |
| qualitative study of paradoxical zone phenomenon of penicillins against 17 bacterial species of clinical importance. | using a triple agar layer technique and enzymatic inactivation of penicillin, the occurrence of a paradoxical zone phenomenon (illustrated by a typical 'target' image around the reservoir of antibiotic) was determined for several bacterial species specially chosen with regards to their taxonomic position, clinical importance and penicillin susceptibility. among gram-positive bacteria, a paradoxical zone was obtained for approximately 43% of the strains studied here (all 10 strains of staphylococ ... | 1978 | 340171 |
| nonspecific immunostimulant activities of synthetic trehalose-6,6'-diesters (lower homologs of cord factor). | mycobacterial cord factors (6,6'-diesters of trehalose with mycolic acids ranging from c80 to c90) have been shown to protect mice effectively against infection with klebsiella pneumoniae or with listeria monocytogenes. our present findings indicate that the low-molecular-weight cord factor of corynebacterium diphtheriae (with corynomycolic acids ranging from c28 pto c36) is equally active. moreover, its synthetic analog (with synthetic c32 mycolic acid) has the same activity. two lower syntheti ... | 1978 | 352926 |
| specific and nonspecific resistance in mice immunized with irradiated myobacterium leprae. | following subcutaneous inoculation of irradiated mycobacterium leprae (i-ml) into the left hind footpad of mice, there was increased resistance to listeria monocytogenes, indicative of macrophage activation, at the immunization site. in spite of the high level of localized macrophage activation which was proportioned to the immunizing dose of i-ml, no such activity could be demonstrated systemically in these mice, as evidenced by the absence of increased resistance to an intravenous challenge wi ... | 1978 | 352954 |
| chorio-meningo-encephalitis due to listeria monocytogenes after renal transplantation. | a 35-year-old man, who underwent renal transplantation, died of meningo-encephalitis with symptoms of meningitis for only 8 days. the autopsy revealed marked chorio-meningo-encephalitis caused by listeria monocytogenes. this report on listeriosis in renal transplant patients is the second in our country, where adult cases of listeriosis are rare. recent knowledge about listeriosis in renal transplants is reviewed and discussed. | 1978 | 362022 |
| listeria monocytogenes: brain abscess or meningoencephalitis? | a brain abscess caused by listeria monocytogenes developed in an immunosuppressed renal transplant patient. meningitis and meningoencephalitis from this organism were encountered in three other renal transplant recipients at this medical center during the past 4 years. focal neurologic deficits occurred in patients with either listeria abscess or meningoencephalitis. computerized tomography was a rapid aid to the diagnosis of abscess. immunosuppression has increased the incidence of central nerv ... | 1979 | 370686 |
| the variable response of bacteria to excess ferric iron in host tissues. | the enhancement by exogenous ferric iron, both systemic and local, of the infectivity of 120 strains of bacteria, representing 17 genera, was measured in the skin of guinea-pigs. systemic iron enhanced only 23% of 115 strains, and local iron 49% of 71 strains. systemic iron, by an apparently anti-inflammatory action, depressed the size of lesions produced by 27 of the non-enhanced strains from nine of the genera tested. for most strains, the degree of enhancement was small, ranging from 2- to 8- ... | 1979 | 372534 |
| hexachlorobenzene-induced stimulation of the humoral immune response in rats. | rats were fed diets containing 0, 500, 1000, and 2000 mg hcb/kg during a 3-week period. marked weight increases of spleen, popliteal and mesenteric lymph nodes and of the liver were found. histologically, the white pulp in the spleen was enlarged because of an increase in size of marginal zones and follicles. in addition, there was an increase of extramedullary hemopoiesis. in the lymph nodes, the number of high endothelial venules was increased at all dose levels. the number of neutrophils, bas ... | 1979 | 378061 |
| effects of bcg infection on the susceptibility of mouse macrophages to endotoxin. | mice infected intravenously with mycobacterium bovis (bcg) are 100 to 1,000 times more sensitive to the lethal effects of bacterial lipopolysaccharides (lps). since bcg infection results in macrophage activation and lps may cause pathophysiological effects through interaction with this cell type, it was of interest to determine whether macrophages from bcg-infected animals were more susceptible to the toxic effects of lps in vitro. when lps-susceptible, c57bl/6 mice were infected with bcg, a sig ... | 1979 | 378847 |
| [inflammation and host resistance against bacteria. i.--increased resistance against listeria monocytogenes and salmonella typhimurium in mice, following their treatment with bradykinin, kallidin and methionyl-lysyl-bradykinin (author's transl)]. | mice pretreated with kinins are more resistant to a lethal challenge of listeria monocytogenes. the multiplication of listeria is decreased in the liver and spleen and the blood clearance of salmonella typhi-murium is increased. | 1979 | 393161 |
| indirect sandwich enzyme-linked immunosorbent assay for rapid detection of haemophilus influenzae type b infection. | we report the development and testing of an enzyme-linked immunosorbent assay with excellent sensitivity for the detection of haemophilus influenzae type b (hi(b)) antigen in clinical specimens from patients with hi(b) meningitis. the assay, an indirect sandwich technique, uses polystyrene balls as a solid phase and an alkaline phosphatase-labeled goat anti-rabbit globulin conjugate. specimens are incubated with polystyrene balls armed with burro anti-hi(b) antiserum, and recognition antibody is ... | 1979 | 393714 |
| effect of sensitization with propionibacterium acnes on the growth of listeria monocytogenes and treponema pallidum in rabbits. | sensitization of rabbits with propionibacterium acnes, a nonspecific stimulant of the reticuloendothelial system, was investigated as a means of enhancing resistance to treponema pallidum. a single i.v. dose of p. acnes given 3 or 7 days before challenge with listeria monocytogenes was capable of suppressing the growth of the heterologous organism, whereas a single i.v. dose 24 hr or 14 days before challenge was not. reactivation via i.v. elicitation with p. acnes 14 days after sensitization (1 ... | 1977 | 401511 |
| effect of amniotic fluid on bacterial growth. | the bacteriostatic effect of amniotic fluid was studied using four pathogenic organisms which are encountered in the perinatal period, e. coli, s. aureus, l. monocytogenes, and group b beta hemolytic streptococci. amniotic fluid inhibited the growth of all four organisms, with a wide degree of individual variation among specimens. the greatest degree of inhibition was noted for l. monocytogenes and the least for e. coli. the time in gestation in which the amniotic fluid sample was obtained did n ... | 1977 | 401535 |
| destruction of experimental malignant melanoma by mediators of cellular immunity. | listeria monocytogenes (lm) in admixture with b-16 melanoma suppresses local tumor development in syngeneic c57bl/6 mice. in vitro, lm-immune peritoneal and splenic cells are cytotoxic to b-16. induction of cell-mediated immunity to lm antigens are required for the killing effect, since effector cells from lm-"immune" athymic nude mice are unable to kill tumor cells in vitro. further, elimination of macrophages by a specific antiserum plus complement abrogates the cytotoxic effect of peritoneal ... | 1977 | 401681 |

| synergism of penicillin and gentamicin against listeria monocytogenes in ex vivo hemodialysis culture. | a new technique of ex vivo hemodialysis culture was used to study the effects against listeria monocytogenes of penicillin g and gentamicin administered intra-muscular, singly and in combination, in the goat. bactericidal synergism of the combination was detected despite rapidly diminishing concentrations of the drugs in the blood plasma and dialysate. | 1977 | 401852 |
| t-cell-mediated concomitant immunity to syngeneic tumors. i. activated macrophages as the expressors of nonspecific immunity to unrelated tumors and bacterial parasites. | progressive growth of the sa1 sarcoma was shown to result in the generation of a state of concomitant resistance to growth of a second implant of the same tumor. the responding lymph nodes of concomitantly immune mice were shown to contain theta-positive t cells that could specifically neutralize the growth of tumor cells in a normal test recipient. nevertheless, the concomitantly immune host itself was capable to a limited extent of suppressing the growth of unrelated tumors. the generation of ... | 1977 | 401860 |
