| enhanced resistance to listeria monocytogenes in splenectomized mice. | mice infected with live listeria monocytogenes intravenously from 1 week to 3 months following splenectomy exhibit greatly enhanced antibacterial resistance to this micro-organism as compared to normal or sham-splenectomized mice. they survive a dose of listeria 100 times higher than is the ld50 of this parasite for normal mice. initially, the same number of viable micro-organisms lodge in the livers of splenectomized and normal hosts. however, within 24 h after infection, the number of viable l ... | 1977 | 412778 |
| anomalous high native resistance to athymic mice to bacterial pathogens. | congenitally athymic (nude) mice exhibited an anomalous high resistance against infections with the facultative intracellular parasite listeria monocytogenes and other bacterial pathogens. protection against lethal infection was demonstrated to result from the presence of naturally occurring activated macrophages in the reticuloendothelial organs of the nude mice. this was exemplified after intravenous challenge by enhanced bacterial clearance from the blood and augmented bacterial killing in th ... | 1977 | 412787 |
| hyperthermia and human leukocyte functions: effects on response of lymphocytes to mitogen and antigen and bactericidal capacity of monocytes and neutrophils. | it has recently been demonstrated that fever, or hyperthermia, results in enhanced survival of lizards infected by aeromonas hydrophila. in the present study, the effects of hyperthermia on certain immune functions were assayed in vitro with purified human leukocytes. lymphocyte transformation responses to the mitogen phytohemagglutinin and the common antigen streptokinase-streptodornase were enhanced at 38.5 degrees c relative to 37 degrees c whether analyzed according to absolute counts per mi ... | 1977 | 412788 |
| immunofluorescent identification of listeria monocytogenes. | a fluorescent antibody technique for the rapid diagnosis and identification of l. monocytogenes in smears, impression smears from tissues of animals dead from listeriosis, and in meat and milk is described. the technique could well be exploited for detecting l. monocytogenes in meat and meat products, animal tissues, and in milk provided that it is supplemented with adequate controls. the technique has been compared with conventional cultural technique and found to be superior as far as the time ... | 1977 | 413282 |
| [certain data on the protoplast ultrastructure]. | a study was made of the structure of bac. subtilis and listeria monocytogenes protoplasts by the method of scanning electron microscopy. the mechanism of protoplast formation in gram-positive bacteria and in spheroplasts of gram-negative bacteria proved to differ. a loss of the rigid form of the cell, round protrusions on cell surface, and an escape of the cytoplasm through the ruptured cell wall in some one place was noted in case of protoplasts. individual cells can coalesce with one another w ... | 1977 | 413293 |

| cellular mechanisms in the protection against infection by listeria monocytogenes in mice. | listeria monocytogenes, in doses of 2-0 x 10(3) to 3-0 x 10(3) viable organisms, was injected into athymic nude mice, irradiated mice and mice treated with reticuloendothelial system-blocking agents. viable counts on liver and spleen homogenates were made at intervals after infection. in both nude mice (nu/nu) and normal littermates (nu/+) of balb/c background, the bacteria grew rapidly for 24 h but increased only slowly thereafter, to reach a plateau of about 10(5) per organ at 72 h. in nu/+ mi ... | 1977 | 302322 |
| 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 |
| 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 |
| [new serovariants and/or antigen combinations of listeria monocytogenes (author's transl)]. | in 2111 samples of human faeces originating from 932 persons (midwives, pregnant women, slaughterhouse workers, laboratory workers, individuals with gastroenteritis and without specific symptoms) a total of 86 (9.22%) carriers of l. monocytogenes could be found. serotyping revealed prevalence of serovar 1/2a (39%) which was characterized by beta-hemolysis and mouse pathogenicity; serovar 4b and 5, also showing beta-hemolysis and mouse pathogenicity, were met with in 11% and 2% of cases, respecti ... | 1977 | 414480 |
| listeria monocytogenes meningitis: case report. | a case of listeria monocytogenes septicaemia with meningitis is described. predisposing factors in this case included chronic liver disease, diabetes mellitus and liver malignancy. the infection responded poorly to ampicillin. | 1977 | 415268 |
| effect of bcg and c. parvum on in vivo listeria clearance and tumor growth. comparative studies in normal and congenitally athymic (nude) mice. | clinically, it is important to know whether agents used for immunostimulation require the presence of functional thymus-derived (t) cells. previous studies showed that both bcg and c. parvum induced a macrophage-dependent enhanced in vivo listeria clearance and in vivo inhibition of a fibrosarcoma induced by 20-methylcholanthrene. these two models were re-evaluated in congenitally thymusless (nude or nu/nu) b10lp mice lacking functional t cells. in nu/nu mice, (1) bcg failed to enhance listeria ... | 1977 | 415917 |
| proposals for quality control methods of bacterial vaccines for immunostimulation. iii. effect of bcg and c. parvum on in vivo listeria clearance and tumor growth. | two quality control methods for bcg and c. parvum are described. first, in vivo macrophage dependent-spleen clearance of listeria monocytogenes in inbred b10lp mice. bcg and c. parvum were administered intravenously prior to listeria inoculation (a prophylactic model). conditions for enhanced listeria clearance including dose, route and time interval were described for each vaccine. next, a tumor model was developed: i.e. a fibrosarcoma, chemically induced by 20-methylcholanthrene in inbred balb ... | 1977 | 415924 |

| [influence of latent vitamin a deficiency of the mouse on the production of humoral antibodies against sheep erythrocytes and on the resistance against infection with listeria monocytogenes (author's transl)]. | mice fed with a vitamin a free diet for several months did not develop signs of vitamin a deficiency. however, chemical analysis revealed a reduced content of vitamin a in the liver of such mice. the ability of these animals were latent vitamin a deficiency to produce antibodies against parenterally applicated sheep erythrocytes was not hampered. similar numbers of antibody producing cells could be detected in the spleen of these mice compared with control animals. resistance against intravenous ... | 1977 | 848214 |
| infection in newborn siblings. | two newborn siblings, one with meningitis and one with sepsis due to listeria monocytogenes, were born to a healthy, 33-year-old woman. she had had a spontaneous abortion prior to the birth of these infants. in spite of negative cultures, persistence of this bacterium in the mother's genital tract and perinatal acquisition of infection is suspected. | 1977 | 848461 |
| a numerical taxonomic survey of listeria and related bacteria. | a numerical taxonomic study was performed on named strains of listeria, erysipelothrix, microbacterium thermosphactum, lactobacillus, streptococus, propionibacterium, kurthia and some possibly related bacteria using i43 unit characters covering a wide range of properties. the strains fell into six main clusters: (a) listeria; (b) microbacterium thermosphactum, lactobacillus, streptococcus; (c) gemella, erysipelothrix; (d) kurthia and mainly aerobic corynebacteria; (e) propionibacterium, staphylo ... | 1977 | 856940 |
| cell-mediated immunity after oral immunization with ribonucleic acid-protein fractions of vibrio cholerae l-form lysates. | oral administration of a single dose of ribonucleic acid-protein fraction of lysates of vibrio cholerae subtype ogawa l-forms induced an increase in cell-mediated immunity in rabbits. this was demonstrated by an increase in leukocyte migration inhibition in peripheral blood leukocytes, in macrophages migration inhibition, and in microbicidal activity against listeria monocytogenes in peritoneal macrophages obtained from orally immunized rabbits. increased cell-mediated immunity was induced mainl ... | 1977 | 863514 |
| central nervous system infections in patients with cancer. changing patterns. | central nervous system infections in patients with cancer at memorial sloan-kettering cancer center from 1971 to 1974 were surveyed and compared with a previous survey from 1955 to 1970. the two periods were similar in that: 1) there was a high incidence of cns infection in patients with lymphoma, leukemia, and head and spine tumors, 2) specific organisms tended to infect patients with certain primary neoplasms, and 3) fungal infections were common and difficult to diagnose. the two periods diff ... | 1977 | 880555 |
| influence of cyclophosphamide on delayed hypersensitivity and acquired cellular resistance to listeria monocytogenes in the mouse. | the effect of a single dose of cyclophosphamide (cy) on delayed type hypersensitivity (dh) and acquired cellular resistance (acr) to listeria monocytogenes infection in mice was studied. intraperitoneal or intracutaneous immunization with l forms of l. monocytogenes did not result in protection against lethal challenge. a positive dh could be observed when cy-treated mice were intracutaneously immunized with 10(8) or more l forms. intraperitoneal injection of viable l. monocytogenes resulted onl ... | 1977 | 885586 |
| [neonatal listeriosis. apropos of 53 cases]. | 53 cases of neonatal listeriosis were seen during the last five years at the intensive care unit for newborn infants (pr minkowski) and the neonatal center (p. varangot) of the port-royal maternity hospital. the significant decline in mortality to 22 p. 100, when compared with previous years, was attributed to improvements in the diagnosis during the first hours of life and the contribution of artificial ventilation. the most frequent initial clinical sign was respiratory distress (58 p. 100) wh ... | 1977 | 903579 |

| bacterial endocarditis due to listeria monocytogenes in a pregnant diabetic. | a case of bacterial endocarditis due to listeria monocytogenes in a pregnant, class d diabetic patient is presented. the importance of obtaining proper cultures and instituting appropriate antibiotic therapy promptly is emphasized. a favorable outcome was achieved in spite of the combined risk to the fetus of maternal diabetes and listeria endocarditis. | 1978 | 618485 |
| chronic active hepatitis, haemolytic anaemia and listeria monocytogenes bacteraemia. | the association of chronic active hepatitis with haemolytic anaemia is well known. both conditions may respond to steroid therapy which, in common with other causes of suppressed t-lymphocyte function, predispose to many types of infection. a case is described in which transient listeria monocytogenes bacteraemia occurred and the patient recovered without antimicrobial therapy. | 1978 | 625461 |
| prosthetic-valve endocarditis due to listeria monocytogenes. | clinical and necropsy observations in the case of a patient with prosthetic-valve endocarditis due to listeria monocytogenes are presented. although rare cases of l. monocytogenes infection of natural cardiac valves have been reported, this represents the first known case of infection of a prosthetic cardiac valve by this organism. | 1978 | 629227 |
| enumeration and ultrastructure of c4-producing free alveolar cells from guinea pig lung. | free alveolar cells from guinea pig lung producing the fourth emoponent of c (c4) were identified, enumerated, and characterized by using anti-c4 fab-peroxidase conjugates in conjunction with transmission electron microscopy. the c4-producing cell population consisted of: 1) alveolar macrophages (am); 2) less well differentiated phagocytes similar in morphology to exudate macrophages; and 3) weakly phagocytic secretory cells with numerous profiles of rough-surfaced endoplasmic reticulum (er). in ... | 1978 | 632583 |
| listeria monocytogenes infection with brain abscess formation--the first case in miyagi prefecture. | a rare type of brain abscess formation caused by infection with listeria monocytogenes was observed in a 2-year-old boy. the patient did not respond to treatment with various antibiotics. the isolated organisms were found to be sero-type 4b. this is the first report of listeria monocytogenes infection in miyagi prefecture. | 1978 | 635896 |

| reversion of dextran sulfate-induced loss of antibacterial resistance by bordetella pertussis. | parenteral injection of dextran sulfate 500 (ds 500; 50 mg/kg of body weight) into mice caused a complete loss of resistance to a sublethal (2 x 10(3) to 5 x 10(3)) infection with listeria monocytogenes. such loss could be prevented by pretreatment of animals with 3 x 10(9) heat-killed bordetella pertussis organisms (po) 5 to 30 days before the administration of ds 500. the increased phagocytic capcity induced by po was only exhausted when a fourfold dose of ds 500, effecting complete loss of an ... | 1978 | 640739 |
| changes in host resistance caused by nocardia brasiliensis in mice: cross-protection against listeria monocytogenes. | listeria monocytogenes was used to study the rate of development, magnitude, and persistence of the antimicrobial resistance engendered by nocardia brasiliensis infection in mice. the growth of listeria in the liver and spleen was more effectively restricted in nocardia-infected mice than in noninfected animals. the development of delayed-type hypersensitivity to the nocardia antigen was closely correlated to the increased resistance to listeria, suggesting that both properties are the consequen ... | 1978 | 640748 |
| suramin effects on macrophage phagolysosome formation and antimicrobial activity. | the effects of suramin on phagolysosome formation and antimicrobial activity of mouse peritoneal macrophages cultivated in vitro have been studied. prolonged in vitro pretreatment of macrophages with high concentrations of suramin caused macrophages to form large fragile phagolysosomes in which the concentrations of the various lysosomal enzymes were inferred to be diminished. in addition, suramin-treated macrophages demonstrated enhanced exocytosis of acid phosphatase during phagocytosis of pol ... | 1978 | 669808 |
| neonatal listeria monocytogenes meningitis. a case report. | the clinical presentation, bacteriological results, treatment, and outcome of listeria monocytogenes meningitis in a newborn infant are described. the neonatal listeriosis was of the late-onset variety, and the infant survived the infection, but hydrocephalus, which necessitated operative relief, developed. although 2 cases of listeria meningitis have previously been described in south africa, and opportunistic listeriosis is known to occur here, this is apparently the first documented case of n ... | 1978 | 675389 |

| [growth of some pathogenic microorganisms on chemically defined media which were proposed for sensitivity testing (author's transl)]. | the growth of 16 bacterial cultures, which belong to the frequently encountered pathogens, in three different chemically defined fluid media was investigated through turbidity measurements in comparison with mueller-hinton-broth. e. coli, salm. dublin, salm. typhi-murium, enterobacter cloacae, proteus mirabilis, pseud. aeruginosa and bac. cereus grew in two of the three tested defined media with approximately the same intensity as in the mueller-hinton broth. staph. aureus grew well only in one ... | 1978 | 730218 |
| listeria pneumonitis: induction of immunity after airborne infection with listeria monocytogenes. | after implantation of approximately 10(3) listeria monocytogenes organisms into the lungs, mice develop an acute pneumonitis with dissemination of infection to a mediastinal lymph node (medln), liver, and spleen. the infections in a medln and spleen resolve in approximately 7 days, but the lung infection persists for a few days longer. pneumonitis is accompanied by a lymphoproliferative response in a medln and spleen, and immunity to listeria is conferred adoptively with medln and spleen cells b ... | 1978 | 730382 |
| [internuclear ophthalmoplegia in infectious encephalitis: observation on a case of listeriosis]. | an internuclear ophthalmoplegia was diagnosed and recorded electro-oculographically in a patient with pontomedullary listeriosis. the etiological differential diagnosis in case of internuclear ophthalmoplegia is discussed. it is emphasized that listeria monocytogenes encephalitis should be considered because this pathology may be electively located in the pontomedullary area and because of the encreasing frequency of human listeriosis. | 1978 | 754276 |
| three phases of phagocyte contribution to resistance against listeria monocytogenes. | 1978 | 418145 | |
| further characterization of listeria monocytogenes serotype 5. | fifteen strains of listeria monocytogenes serotype 5 were characteriized for carbohydrate utilization, enzymic reactions, and other differential criteria. hemolytic patterns were tested on ovine, bovine, equine, human and lapine blood agars. results were compared with those of previously reported strains of l. monocytogens serotype 5. | 1978 | 418861 |
| impaired chemotactic responsiveness of macrophages from gnotobiotic rats. | peptone-induced macrophages obtained from gnotobiotic (gb) rats responded poorly to chemotactic stimuli that have a powerful, attractive influence upon the cells of conventional donors. monocyte recruitment from the circulation into peptone-induced exudates also was impaired in gb subjects. although relatively more resident cells are present in exudates borne by gb donors, their number cannot in itself account for the sluggish response of peptone-induced cells from gb rats. neutrophil accumulati ... | 1978 | 415979 |

| in vitro susceptibility of listeria monocytogenes to some antibiotics and their combinations. | the listeria monocytogenes strains isolated during recent years in our hospital have been tested for in vitro susceptibility against eleven antibiotics. the following tests were used: antibiotics discs method on mueller-hinton agar, determination of mics by agar dilution method, study of the bactericidal potency of antibiotics combinations. antibiotic discs method gives some too optimistic results, not confirmed by the mics determined with agar dilution method. ther are a few antibiotics used al ... | 1978 | 416625 |
| listeria encephalitis in five renal transplant recipients. | listeria encephalitis has occurred recently in 5 renal transplant recipients at the transplantation unit in stockholm. symptoms from the central nervous system, such as coma, hemiparesis and cranial nerve paresis, dominated the clinical picture. listeria monocytogenes was isolated from the blood of all the patients, from the cerebrospinal fluid in two, from the urine in one and post mortem from the brain in one patient. pleocytosis never exceeded 200 leucocytes/mm3 and the glucose ratio was norm ... | 1978 | 416653 |
| resistance and susceptibility of mice to bacterial infection: course of listeriosis in resistant or susceptible mice. | resistance and susceptibility to listeria monocytogenes in mice was found to be related to (i) the innate ability of the nonimmune macrophages to kill or inhibit the growth of the organism during the first 24 to 48 h after infection, and (ii) the time of onset of acquired cell-mediated resistance. resistant c57bl/6 mice were 10 times more efficient than susceptible balb/c mice at suppressing the early growth of listeria in the liver. furthermore, the onset of acquired immunity occurred 24 to 48 ... | 1978 | 417029 |
| development of listeria monocytogenes in monoxenic and polyxenic beef minces. | the objective of this study was to determine the multiplication possibilities of listeria monocytogenes in beef minces with a defined microflora (gnotoxenic). selective counts were made for each species and each bacterial association for a period of 17 days after inoculation of the axenic meat. the concentration of l. monocytogenes did not increase, but remained constant in monoxenic meats. associated with lactobacillus plantarum, the number of listeria tended to decrease. conversely, in associa ... | 1978 | 417516 |

| induction of cell-mediated immunity to mycobacterium leprae in mice. | the immune response of mice to armadillo-derived, irradiation-killed mycobacterium leprae (i-ml) was investigated. following injection of 100 microgram of i-ml into the left hind footpads of mice, a state of cell-mediated immunity (cmi) was engendered to antigens of m. leprae. the evidence for cmi was as follows: (i) development of delayed-type hypersensitivity to both human tuberculin purified protein derivative and soluble m. leprae antigens; (ii) t-lymphocyte-dependent macrophage activation a ... | 1978 | 415009 |
| a case of listeriosis in pregnancy with fetal survival. | listeriosis during pregnancy is generally considered to result in an intrauterine infection which affects the fetus before birth or in the perinatal period. a case of listeriosis in a 38-yr-old diabetic woman with an influenza-like disease in her 32nd wk of pregnancy is presented. two successive blood cultures were positive for listeria monocytogenes type 4b and her serum showed a rising titer for agglutinins to this organism. after antibiotic treatment of the patient she gave birth to a healthy ... | 1978 | 264070 |
| activation of reticuloendothelial system macrophages and enhancement of host resistance to a transplantable osteogenic sarcoma in mice by an extract of brucella abortus. | an aqueous-ether extract of brucella abortus, bru-pel, enhanced resistance of mice to a transplantable osteogenic sarcoma (ogs). the results presented in this report suggest that bru-pel is an effective immunomodulator and that one mechanism through which it enhances host resistance is activation of phagocytic cells of the reticuloendothelial system. peritoneal macrophages from mice inoculated with bru-pel 14 days previously were cytotoxic for ogs cells in vitro, limited the multiplication of va ... | 1978 | 282007 |
| 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 |
| 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 |
