| growth of mycobacterium avium in activated macrophages harvested from inbred mice with differing innate susceptibilities to mycobacterial infection. | the growth of mycobacterium avium in macrophages obtained from mycobacterium bovis bcg-infected mice was compared with that in macrophages from uninfected mice. bcg vaccination resulted in substantial macrophage activation, measured as increased acid phosphatase and superoxide anion production, as well as enhanced leishmanicidal activity. however, the activated macrophages were only able to reduce the rate of intracellular growth by listeria monocytogenes and m. avium in vivo and did not express ... | 1988 | 3137164 |
| intracellular interference with antigen presentation. | murine peritoneal macrophages were cultured with heat-killed listeria monocytogenes organisms and then with the protein hen egg white lysozyme. hen egg lysozyme is well known to need intracellular processing for presentation to t cells. the presentation to t cells of lysozyme was affected despite no reduction in the amount taken up or catabolized by the macrophage. this interference with ag presentation was not found if the macrophages were cultured with lysozyme before the listeria pulse. the i ... | 1988 | 3137257 |
| epidemic listeriosis associated with mexican-style cheese. | in los angeles county, california, 142 cases of human listeriosis were reported from january 1 through august 15, 1985. ninety-three cases (65.5 percent) occurred in pregnant women or their offspring, and 49 (34.5 percent) in nonpregnant adults. there were 48 deaths: 20 fetuses, 10 neonates, and 18 nonpregnant adults. of the nonpregnant adults, 98 percent (48 of 49) had a known predisposing condition. eighty-seven percent (81 of 93) of the maternal/neonatal cases were hispanic. of the listeria m ... | 1988 | 3137471 |

| evaluation of selective direct plating media for their suitability to recover uninjured, heat-injured, and freeze-injured listeria monocytogenes from foods. | six direct plating media were evaluated for their suitability to recover uninjured, heat-injured, and freeze-injured cells of four strains of listeria monocytogenes from four foods. cells were inoculated into foods to achieve ca. 10(2) to 10(3), 10(4) to 10(5), or 10(5) to 10(6) viable cells per ml or g (low, medium, and high populations, respectively). no appreciable differences in recovery of the four test strains within a treatment were observed. generally, recovery on all test media was simi ... | 1988 | 3137864 |
| monoclonal antibodies which identify a genus-specific listeria antigen. | fifteen murine monoclonal antibodies (mabs) which react specifically with a protein antigen found in all species of listeria were developed and characterized. these mabs were tested extensively by both enzyme-linked immunosorbent assay and western blot (immunoblot) analyses for cross-reaction with non-listeria organisms, such as staphylococcus, streptococcus, citrobacter, pseudomonas, and salmonella species, and were found to be nonreactive. the genus-specific antigen was identified as a heat-st ... | 1988 | 3137865 |
| increased bactericidal macrophage activity induced by immunological stimuli is dependent on interferon (ifn)-gamma. interference of anti-ifn-gamma but not anti-ifn-alpha/beta with modulation of macrophage activity caused by lymphocytic choriomeningitis virus infection or systemic graft-vs.-host reactions. | during generalized immune responses such as the acute phase of graft-vs.-host reaction (gvhr) or many systemic viral infections the macrophage-monocyte system of mice is activated as demonstrated by their increased bactericidal capacity against listeria monocytogenes. to study the effect of interferon (ifn)-gamma in maintainance of macrophage activity, lymphocytic choriomeningitis virus (lcmv) primed c57bl/6 mice or (c57bl/10 x b10.br) f1 mice undergoing a gvhr were treated with polyclonal speci ... | 1988 | 3138138 |
| endogenous tumor necrosis factor (cachectin) is essential to host resistance against listeria monocytogenes infection. | during a sublethal murine infection with listeria monocytogenes cells, tumor necrosis factor (tnf) activity was detectable in neither sera nor spleen homogenates at any stage of the infection when a bioassay with l-929 cells (less than 4 u/ml) was used. however, injecting the mice with an immunoglobulin fraction obtained from a rabbit hyperimmunized with recombinant murine tnf-alpha resulted in acceleration of listeriosis. when 1 mg of anti-tnf antibody was injected per mouse, all the mice died ... | 1988 | 3138177 |
| histomorphology of experimental listeriosis. | this paper is a survey of the histomorphology of experimental listeriosis based on cooperative studies performed within the past ten years. the influence of various parameters of the infectious agent (pathogenic listeria monocytogenes serovar 4b, nonpathogenic listeria innocua serovar 6b etc.) as well as of the host (euthymic nmri-mice conditioned with dextran sulfate 500 or cyclosporin a, athymic nude mice etc.) on the course, morphology and outcome of the listeria infection was investigated. f ... | 1988 | 3138181 |
| alteration of non-specific resistance to infection with listeria monocytogenes. | the experimental infection of murine hosts with listeria monocytogenes is often used as a model for cell-mediated immunity. however, the natural immunity or non-specific resistance to listeriosis can be influenced by the parasite itself and also by a wide array of endogenous and exogenous host factors. the most important host factor in inbred mouse strains is their genetically determined susceptibility or resistance to listeria monocytogenes. secondly, the age of the mice is crucial for the outc ... | 1988 | 3138182 |
| comparison of responsiveness to the monocytosis-producing activity of listeria monocytogenes in mice genetically susceptible or resistant to listeriosis. | injection of a monocytosis producing activity (mpa) from listeria monocytogenes caused a dose-dependent elevation in numbers of macrophage colony forming units (cfu-m) in bone marrow and in peripheral blood. the increase could be seen as early as 8 h after injection of mpa and persisted until 72 h after injection. serum from mpa-treated animals, capable of inducing monocytosis, also caused an elevation in numbers of cfu-m. the effect of mpa on cfu-m numbers in peripheral blood was measured in in ... | 1988 | 3138183 |
| the role of t cell subpopulations in cell mediated immunity to facultative intracellular bacteria. | this brief review summarizes the experimental data which underly the classic concept of antibacterial cell mediated immunity and will integrate recent developments focusing on results obtained by in vivo studies in the model of rodent listeriosis. | 1988 | 3138184 |
| listeria monocytogenes specific t-cell lines and clones. | evidence is summarized to suggest that both cd4 and cd8 t cells and both helper and cytolytic t cell functions are involved in protective immunity to infection with the intracellular bacterium, listeria monocytogenes. this suggestion is based on the following findings obtained with t cell lines and clones from l. monocytogenes infected mice: l3t4+ (cd4) t cells produce multiple lymphokines after antigen stimulation in vitro; lyt2+ (cd8) t cells lyse l. monocytogenes primed macrophages; l3t4+ (cd ... | 1988 | 3138185 |
| roles of factor increasing monocytopoiesis (fim) and macrophage activation in host resistance to listeria monocytogenes. | the present contribution concerns two aspects of host resistance in overcoming an infection with listeria monocytogenes. one of these aspects is the regulation of monocyte production by the factor increasing monocytopoiesis (fim), a macrophage-derived factor. listeria-resistant (c57bl/10 mice and listeria-sensitive cba mice produce and secrete similar amounts of fim in response to an inflammation induced by soluble listeria antigen. however, monocyte precursors in the bone marrow of listeria-res ... | 1988 | 3138186 |
| pathogenicity of listeria monocytogenes in comparison to other listeria species. | in different mouse models the pathogenicity of various strains of listeria monocytogenes and of other listeria spp. was evaluated. although quantitative differences of virulence among strains of l. monocytogenes are found, all isolates have to be regarded pathogenic unless essential virulence factors, such as protein composition of the cell wall or hemolysin production, are lacking. besides l. monocytogenes, only listeria ivanovii is able to multiply in the murine host, though definitely to a le ... | 1988 | 3138187 |
| invasiveness and intracellular growth of listeria monocytogenes. | listeria monocytogenes is an invasive bacterial pathogen capable of multiplying inside many host cells, including macrophages, enterocytes and hepatocytes. there is evidence to believe that secretion of listeriolysin o, an sh-activated exotoxin, is crucial for bacterial growth in host tissues. this exotoxin is stimulated in iron-deprived medium and mostly active at low ph (5.5). electron microscopic studies showed that intracellular bacteria rapidly disrupt the vacuole membrane of phagosomes and ... | 1988 | 3138188 |
| hemolysin from listeria--biochemistry, genetics and function in pathogenesis. | thiol-activated hemolysins (listeriolysins) from listeria monocytogenes (sv4b) and listeria ivanovii were purified to homogeneity. the n-terminal amino acid sequences of the 58 kda listeriolysin of l. ivanovii and of a 24 kda protein which may represent the camp-factor of l. ivanovii were determined. antibodies raised against the l. ivanovii listeriolysin and anti-streptolysin o antibodies were used in western blot analyses to detect listeriolysin(s) in virulent and avirulent listeria strains. i ... | 1988 | 3138189 |
| liposome-encapsulated ampicillin against listeria monocytogenes in vivo and in vitro. | in an experimental infection caused by listeria monocytogenes in mice a considerable enhancement (90-fold) of the therapeutic activity of ampicillin resulting from liposomal encapsulation was observed. the mechanism by which liposomes improved the therapeutic index of ampicillin in this infection appeared to be an increased delivery of the antibiotic to the site of infection, i.e. the liver and spleen. substantial amounts of liposomal ampicillin were recovered from isolated kupffer cells, the ta ... | 1988 | 3138190 |
| therapy of experimental listeriosis--an evaluation of different antibiotics. | the therapeutic activities of various antibiotics were evaluated in two murine models, i.e. the infection of normal mice as well as of nude mice. coumermycin and rifampicin were the most active drugs, since not only inhibition of multiplication but also rapid elimination of listeria monocytogenes could be achieved in normal and immunocompromised animals. ampicillin was the most active beta-lactam antibiotic followed by azlocillin. the other beta-lactam antibiotics were definitely less active. th ... | 1988 | 3138191 |

| generation of listeria monocytogenes-specific t cells mediating delayed footpad reaction and protection in neonatally thymectomized mice but not in nude mice. | neonatally thymectomized (ntx) mice, sham-operated control mice and congenitally athymic nude mice were immunized with viable listeria monocytogenes and their spleen cells examined for the capacity to transfer both delayed footpad reaction and protection against challenge at the site of local transfer. cells from immune ntx mice conferred significant degrees of delayed footpad reaction and protection comparable to sham mice, while cells from immune nude (nu/nu) mice did not. this ability was com ... | 1988 | 3138516 |
| differential effect of t-2 toxin on murine host resistance to three facultative intracellular bacterial pathogens: listeria monocytogenes, salmonella typhimurium, and mycobacterium bovis. | the effect of t-2 toxin, a radiomimetic immunosuppressive agent, on resistance to the facultative intracellular bacterial pathogens listeria monocytogenes (strain egd), mycobacterium bovis (bcg copenhagen 1331), and salmonella typhimurium was determined. female swiss icr mice were given a single dose of t-2 toxin (4 mg/kg of body weight) by gastric gavage. on the seventh day after toxin administration, the mice were infected by intraperitoneal inoculation with l monocytogenes, s typhimurium, or ... | 1988 | 3138932 |
| foodborne listeriosis. who working group. | listeria monocytogenes is widely distributed in the environment and may be transmitted to man through contamination of foodstuffs at any point from source to kitchen. milk and dairy products, meat, poultry, vegetables, salads and seafoods have all been found to be contaminated. unlike most other foodborne pathogens, l. monocytogenes can multiply in refrigerators (4-6 degrees c). pasteurization reduces their numbers in raw milk to levels that do not pose an appreciable risk to human health.the in ... | 1988 | 3139313 |
| further serological investigations in humans and domestic animals on the cape verde islands (q-fever, brucellosis, listeriosis, shigellosis, campylobacteriosis, yersiniosis, toxoplasmosis and chlamydia of plt-group). | 439 sera of domestic animals and various number (150-500) of human sera of the cape verde islands were examined for antibodies against coxiella burnetti, brucella abortus, b.melitensis, listeria monocytogenes, shigella dysenteriae, s.flexneri, s. boydii, s.sonnei, campylobacter jejuni, c.fetus ssp. intestinalis, yersinia enterocolitica, toxoplasma gondii and chlamydia of the plt-group. it could be shown, that on the cape verde islands there is to be counted with numerous zoonoses due to various ... | 1988 | 3139491 |
| in vitro primary induction of t cells mediating delayed footpad reaction and acquired cellular resistance to listeria monocytogenes. | 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 ... | 1988 | 3139549 |

| early influx of listeria-reactive t lymphocytes in liver of mice genetically resistant to listeriosis. | murine listeriosis is a classical model for investigating mechanisms of cellular immunity, which involves interaction of macrophages and t lymphocytes. the early course of this experimental infection is under control of a limited number of genes in the murine host. in the present study, we asked whether the early efficient control of bacterial growth in the liver of resistant mice is related to the expression of a more rapid specific immune response in this organ than in susceptible mice. theref ... | 1988 | 3139760 |
| synergistic therapeutic effect of combination therapy with ok-432 and interferon-alpha or -gamma on meth-a ascites tumor in balb/c mice. | a synergistic therapeutic effect on meth-a ascites tumor was obtained in balb/c mice by the simultaneous i.p. injection of ok-432 and interferon alpha a/d (ifn-alpha). balb/c mice that were cured of their meth-a tumors showed significant tumor-specific rechallenge resistance. combined therapeutic effect was significantly weaker in nude mice than in haired mice. the stimulation of host t-cell immunity was indicated to be crucially important for obtaining cured mice. natural killer activity of per ... | 1988 | 3139841 |
| virulence of listeria spp.: course of infection in resistant and susceptible mice. | the virulence of representative strains of the five species of listeria monocytogenes sensu lato was compared in c57bl/6 and balb/c mice in terms of ld50 values and of bacterial growth kinetics and histological changes in mouse livers. l. monocytogenes sensu stricto and l. ivanovii showed relatively low ld50 values and much bacterial growth for 2-3 days before viable counts declined. histological changes in l. ivanovii infection resembled those caused by l. monocytogenes, with early development ... | 1988 | 3139882 |
| induction of nonspecific acquired resistance and delayed-type hypersensitivity, but not specific acquired resistance in mice inoculated with killed mycobacterial vaccines. | a number of nonliving mycobacterial preparations were tested in vivo for their capacity to generate various relevant parameters of cellular immunity. all preparations tested had some detectable activity in raising resistance to challenge with mycobacterium tuberculosis or with listeria monocytogenes and in conferring the ability to mount a delayed-type hypersensitivity response to tuberculin. this report presents the first evidence, however, that none of these preparations were able to generate ... | 1988 | 3141288 |
| inhibitory effect of tetracycline and doxycycline on resistance of mice to infection with a tetracycline-resistant strain of listeria monocytogenes. | by transposon mutagenesis a tetracycline-susceptible strain of listeria monocytogenes (mic 1 mg/l. for tetracycline and 0.25 mg/l. for doxycycline) was rendered resistant (mic 64 mg/l. for tetracycline and 16 mg/l. for doxycycline). infection of mice with this resistant strain led to an acute infection. treatment with 2 x 2 mg tetracycline per day did not influence the course of infection during the first 3 days, indicating that the nonspecific resistance, mediated mainly by macrophages and gran ... | 1988 | 3141304 |
| increased natural resistance to listeria monocytogenes in senescent mice correlates with enhanced macrophage bactericidal activity. | natural resistance to listeria monocytogenes is increased in aging (18-22-month-old) ab6f1 mice when compared to their younger counterparts. we have investigated several parameters of macrophage function of old ab6f1 mice to establish what macrophage characteristics determine their enhanced resistance to listeria. senescent mice had an increased number of macrophages present in unstimulated peritoneal cavity. these macrophages exhibited enhanced bactericidal activity and h2o2 production. old mic ... | 1988 | 3141495 |
| psk, a polysaccharide from coriolus vesicolor, enhances oxygen metabolism of murine peritoneal macrophages and the host resistance to listerial infection. | psk, a protein-bound polysaccharide isolated from the basidiomycete coriolus vesicolor (fr.) quél. was examined with regard to its effects of macrophage (m phi) oxygen metabolism in mice, a function important for the expression of m phi antimicrobial activity. the o2(-)-producing ability and chemiluminescence (cl) of host peritoneal m phi s in response to phorbol myristate acetate were markedly elevated by preinjection of psk (1 or 5 mg per mouse intraperitoneally) around 4-7d before m phi-harve ... | 1988 | 3141579 |
| [listeria monocytogenes kerato-uveitis]. | an 86-year-old patient with corneal gutae and diabetes presented with a listeria monocytogenes serpent ulcer on her right eye. smears taken from the ulcer revealed listeria monocytogenes serotype 4b. despite specific antibiotic therapy including cephalosporins and systemic administration of amikacin, as well as topical gentamycin drops, the eye had to be enucleated on the 16th day after hospitalization. massive fibrinous reaction and extreme pain causing the patient to reject alimentation were t ... | 1988 | 3141669 |
| parasite-directed endocytosis. | following the attachment of gonococci to human fallopian tube mucosa in organ culture, the gonococci are endocytosed by specialized low columnar epithelial cells, are transported to the base of the epithelial cells, and are subsequently exocytosed into the subepithelial tissues. this transepithelial transport process by which "invasion" of the host occurs appears to be dependent on microbial factors is designated parasite-directed endocytosis to distinguish it from host-directed endocytosis by c ... | 1988 | 3142016 |

| serological investigations for some bacterial and viral pathogens in fallow deer (cervus dama) and wild boar (sus scrofa) of the san rossore preserve, tuscany, italy. | sera of 43 fallow deer (cervus dama) of the san rossore preserve (tuscany, italy) were examined for antibodies against eight pathogens; one proved positive for brucella sp., 21 for listeria monocytogenes, 34 for chlamydia psittaci, three for coxiella burnetii, one for infectious bovine rhinotracheitis virus, 11 for parainfluenza-3 virus, 25 for bovine viral diarrhea virus and six for bovine respiratory syncytial virus. no age and sex difference in the positivity rates and titers was evidenced, w ... | 1988 | 2832622 |
| role of hemolysin for the intracellular growth of listeria monocytogenes. | listeria monocytogenes insertion mutants defective in hemolysin production were generated using the conjugative transposons tn916 and tn1545. all of the nonhemolytic mutants (hly-) lacked a secreted 58-kd polypeptide, presumedly hemolysin, and were avirulent in a mouse model. an intracellular multiplication assay was established in monolayers of mouse bone marrow-derived macrophages, the j774 macrophage-like cell line, the cl.7 embryonic mouse fibroblast cell line, and the henle 407 human epithe ... | 1988 | 2833557 |
| tumor necrosis factor, alone or in combination with il-2, but not ifn-gamma, is associated with macrophage killing of mycobacterium avium complex. | organisms belonging to the mycobacterium avium complex (mac) are the most common bacterial pathogens in patients with aids but factors associated with the activation of cellular defense mechanisms against this atypical mycobacterium have not been defined. peritoneal macrophages harvested from a chronic mac infection in c57 black mice are able to kill approximately 86% of intracellular mac in contrast to 0 to 20% killing by unstimulated human and mouse macrophages in vitro. the availability of hu ... | 1988 | 2834450 |
| the pathology of aids. | the acquired immunodeficiency syndrome (aids) is a devastating new disease caused by the human immunodeficiency virus (hiv). this retrovirus causes profound immunoincompetence in its infected hosts, who are thereafter susceptible to develop myriad severe and relapsing protozoal, fungal, bacterial, viral, and arthropodal opportunistic infections, as well as unusual malignancies. the more than 50,000 patients who have developed aids in the united states have produced a sudden unexpected deluge of ... | 1988 | 2836878 |
| in vitro activities of azithromycin (cp 62,993), clarithromycin (a-56268; te-031), erythromycin, roxithromycin, and clindamycin. | the in vitro activity of azithromycin (cp 62,993 or xz-450) against haemophilus influenzae was greater than that of three other macrolides. however, azithromycin was four- to eightfold less active than erythromycin against the gram-positive cocci and against listeria monocytogenes. erythromycin and azithromycin were similar in their activity against legionella pneumophila, neisseria gonorrhoeae, neisseria meningitidis, and branhamella catarrhalis. | 1988 | 2840016 |
| [immunomodulating properties of salmozan and its effect on the functional activity of macrophages]. | the effect of salmozan on the resistance of mice to listeria monocytogenes infection, the formation of delayed hypersensitivity (dh) to sheep red blood cells in the animals, as well as changes in some functional activity characteristics of macrophages have been studied. the study has revealed that salmozan enhances anti-infectious resistance, suppresses the dermal manifestations of dh, and decreases the level of 5'-nucleotidase in peritoneal macrophages, stimulating their phagocytic activity. th ... | 1988 | 2842987 |
| the listeriolysin o gene: a chromosomal locus crucial for the virulence of listeria monocytogenes. | in culture supernatants of a tn 1545-induced non-hemolytic mutant of listeria monocytogenes, by immunoblotting with an anti-serum raised against purified listeriolysin o, we have detected the presence of a truncated protein of 52,000d (the secreted listeriolysin o is 60,000d). the region of insertion of the transposon has been cloned and sequenced. the transposon had inserted in an open reading frame. the homologies detected between this orf, streptolysin o and pneumolysin demonstrate the the tr ... | 1988 | 2843472 |
| gamma-interferon restores listericidal activity and concurrently enhances release of reactive oxygen metabolites in dexamethasone-treated human monocytes. | by preventing macrophages from destroying phagocytized microorganisms, glucocorticoids lower natural resistance of the host against many pathogens. gamma-interferon has an opposite effect and restores activity of dexamethasone-treated mononuclear phagocytes against some but not all microorganisms. in the present studies we show that dexamethasone impairs activity of human blood monocytes kept in culture for 36 h against listeria monocytogenes, without impairing h2o2 or o2- secretion. likewise de ... | 1988 | 2843576 |

| susceptibility of hrs/j mice to listeriosis: dynamics of infection. | congenitally hairless hrs/j homozygous (hr/hr) mice as well as phenotypically normal littermates (hr/+) were found to exhibit unusual susceptibility to infection with listeria monocytogenes with 50% of the animals dying within a 10-day period (ld50) at an infecting inoculum approaching 200 microorganisms. in marked contrast to the outbred cd-1 strain as well as other listeria-susceptible mice, hrs/j hosts are virtually incapable of limiting infection with virulent listeria. the dynamics of infec ... | 1988 | 3343051 |
| effect of combined treatment of anti-inflammatory drug and mannoheptulose on the production of tumour necrosis factor and endotoxin shock in mice. | the endotoxin shock induced in mice by injection of viable listeria monocytogenes and challenged with endotoxin can be alleviated by combined administration of mannoheptulose with acetylsalicylate or sulindac. the ability of animals to secrete tumour necrosis factor into the blood was, however, not affected. the significance of these observations are discussed. | 1988 | 3359411 |
| successful surgical treatment of a case of listeria monocytogenes endocarditis. | endocarditis due to listeria monocytogenes is rare with only twenty one cases to our knowledge appearing in the world's literature to date. we report a further case with a successful surgical outcome and stress the importance of surgery in the treatment of infective endocarditis. there is a clear predilection of this organism for the left side of the heart and systemic embolization is frequent. in contrast to other clinical forms of listeriosis, endocarditis has not been associated with debilita ... | 1988 | 3360833 |
| tumor necrosis factor alpha in cerebrospinal fluid during bacterial, but not viral, meningitis. evaluation in murine model infections and in patients. | to evaluate the potential role of cachectin/tnf-alpha in the pathogenesis of bacterial and viral meningitis, concentrations and kinetics of tnf-alpha were determined in cerebrospinal fluid (csf). after intracerebral, but not systemic, infection with listeria monocytogenes in mice, tnf-alpha was detected as early as 3 h after infection reaching maximum titers after 24 h. however, tnf-alpha was not found in serum during the course of listeria infection. in contrast to bacterial meningitis, no tnf- ... | 1988 | 3367098 |

| listeriosis in the united states: 1980-1982. | the magnitude of the public health problem associated with listeria monocytogenes in the united states has been unknown, and the route of transmission is largely undetermined. investigations of recent outbreaks, however, have shown that the infection can be foodborne. we estimated the expected frequency of sporadic listeriosis based on hospital discharge data from the professional activity study of the commission on professional and hospital activities for the years 1980 through 1982. the incide ... | 1988 | 3377624 |
| perinatal listeriosis underdiagnosed as a cause of pre-term labour? | between april 1, 1985, and april 1, 1986, four cases of perinatal listeriosis were reported at the maastricht academic hospital. all cases were of the early-onset type. all mothers were admitted for pre-term labour between 28 and 33 weeks of gestation. pre-natal symptoms included maternal fever, non-characteristic influenza-like manifestations, leucocytosis and (pre-term) meconium-stained amniotic fluid. two neonates died, one in utero and one due to listeriosis sepsis. another neonate developed ... | 1988 | 3384163 |
| sera from patients with high titers of antibody to streptolysin o react with listeriolysin. | sera of patients with suspected rheumatic fever and elevated titers of antibody to streptolysin o were examined by an immunoblotting technique. all but two serum samples, which yielded relatively low titers, bound to a 60-kilodalton protein in the supernatant from a culture of listeria monocytogenes, which presumably represents the listeriolysin. | 1988 | 3384901 |
| effects of ozone on the defense to a respiratory listeria monocytogenes infection in the rat. suppression of macrophage function and cellular immunity and aggravation of histopathology in lung and liver during infection. | we have investigated the effect of exposure to ozone on defense mechanisms to a respiratory infection with listeria monocytogenes in the rat. for this purpose rats were continuously exposed to o3 concentrations ranging from 0.25 to 2.0 mg/m3 for a period of 1 week. in this model defense to a respiratory infection with listeria depends on acquired specific cellular immune responses, as well as on natural nonspecific defense mechanisms. the results confirm earlier findings that show that ozone exp ... | 1988 | 3400093 |
