killing in vitro of trypanosoma cruzi by macrophages from mice immunized with t. cruzi or bcg, and absence of cross-immunity on challege in vivo.	peritoneal macrophages from t. cruzi-immune mice were resistant to infection in vitro with culture forms of the parasite. macrophage resistance appeared in infected mice about 21 days postinfection when parasitemia was still rising. resistance in vitro was nonspecific since macrophages from bcg-immune mice were resistant to t. cruzi, and since macrophages from t. cruzi-immune mice were resistant to infection in vitro with listeria were not resistant to challenge with t. cruzi even when the par ...	1975	806649
rate of listeria monocytogenes shedding from frogs.	leopard frogs (rana pipiens) were orally inoculated with listeria monocytogenes. most listeriae were shed 3-6 days after inoculation. the evidence indicated that the listeriae did not multiply in frogs and were unable to become established in the gastrointestinal tract.	1975	806711

incidence of listeria monocytogenes in nature.	during a research project on the occurrence of listeria monocytogenes 194 strains were isolated in southern west germany during the years 1972 to 1974:154 from soil and plant samples (20.3%), 16 from feces of deer and stag (15.7%), 9 from old moldy fodder and wildlife feeding grounds (27.2%), and 8 from birds (17.3%). the highest number of isolates was obtained from uncultivated fields. the beta-hemolytic serovars 1/2b and 4b were were predominant; other serovars (some of them identified for the ...	1975	807164
phagocytosis and intracellular killing of staphylococcus aureus by normal mouse peritoneal macrophages.	although staphylococcus aureus is incapable of intracellular multiplication in cultured mouse peritoneal macrophages, it is killed at a much slower rate than the avirulent staphylococcus epidermidis. in addition to the presence of capsular material which inhibits phagocytosis of specific strains of s. aureus, the data show that a number of cellular and environmental factors affect the functional capacities of mononuclear phagocytic cells. the data obtained by varying the initial level of infecti ...	1975	807524
listeria monocytogenes infection in nude mice.	as compared to phenotypically normal (nu/+)nmri mice showing the typical course of an experimental listeric infection, that of congenitally hypothymic (nude, nu/nu)nmri mice was found to be characterized from the outset bya chronic trend. during the early phase of the infection, significantly reduced numbers of listeria monocytogenes were observed in the spleens of nude mice.	1975	807526
activated macrophages in congenitally athymic "nude mice" and in lethally irradiate mice.	resistance to the facultative intracellular bacteria, brucella abortus and listeria monocytogenes, is principally the result of acquisition of enhanced antibacterial activity by host macrophages, probably in response to lymphokines released by t lymphocytes. however, the present paper describes a surprisingly high resistance on the part of both congenitally athymic "nude" mice and of lethally irradiated mice compared with normal controls. this enhanced bactericidal activity was evident 24 hr aft ...	1975	807647
specific detection and semiquantitation of micro-organisms in tissue by nucleic acidhybridization. i. characterization of the method and application to model systems.	on the basis of circumstantial evidence, a number of human diseases have been postulated to result from the presence of occult infection. to investigate this problem amethod of specifically detecting and semiquantitaing trace quantities of bacterial dna in infected tissue has been devised. it is based on rna-dna hybridization using radiolabeled rnacomplementary to the dna of the organism being sought. the characteristics of the reaction are shown to conform to those expected for rna-dna hybri ...	1975	807659
listeria monocytogenes isolated from wapiti (cervus canadensis roosevelti).	serotypes 1 and 4 listeria monocytogenes were isolated from 14 of 72 wapiti among four of five herds studied in northwestern california. more isolations of listeria were made during the summer months than during the other months of the study from one of the herds. the pathogenicity of the strains varied with their ability to ferment xylose and rhamnose.	1975	807750
listeria monocytogenes septicemia in pregnancy.	a case of listeria monocyto-enes septicemia in a patient with a poor reproductive history is presented. the clinical aspects and implications of this infectious disease during pregnancy are discussed, and the role of listeria as a cause of recurrent pregnancy wastage is summarized.	1975	807894
[diagnosis of listeria monocytogenes by immunofluorescence].	for precision of bacteriological diagnosis of listeria monocytogenes (l. m.) the immune fluorescent technique (ift) was assessed. on using the described immunization pattern high titres of specific antibodies were obtained from the immunized rabbits. the obtained hyperimmune sera yielded very good results when used in ift, and they were suitable for conjugate production. by means of ift l.m. was demonstrated from cultures, organ replicas and tissue sections of experimentally infected rabbits. th ...	1975	808008
effect of corynebacterium parvum on the course of a listeria monocytogenes infection in normal and congenitally athymic (nude) mice.	spleen counts of listeria monocytogenes in normal mice challenged with various numbers of organisms were generally lower in mice injected 3 days previously with killed corynebacterium parvum. this increased resistance was unexpected since c. parvum generally inhibits t cell-mediated immunity, the functional immunity against listeria being t cell-dependent. the inhibitory effect on t cells seemed to be compensated by the stimulatory effect of c. parvum on macrophages. therefore, the experiments w ...	1975	808049
interrelations between mammals and pathogens of some bacterial diseases.	various interrelations of mammals with some bacterial pathogens are analyzed. plaque and tularemia are the most thoroughly investigated infectious diseases in this respect. the importance of a different degree of susceptibility and sensitivity to infection for its development in mammalian reservoirs is underlined.	1975	808461
cytotoxicity mediated by soluble macrophage product(s).	the soluble macrophage product(s) released by nonimmune mouse peritoneal macrophages exposed to endotoxin or from listeria-immune macrophages after incubation with specific antigen mediated cytotoxic activity against malignant cell types and, to a lesser extent, against normal cells. only undiluted supernatants from nonimmune or listeria-immune macrophages cultured with medium 199 alone exerted some degree of cytotoxicity on the different target cell types tested. the macrophage product(s) retai ...	1975	808640

nature of "memory" in t-cell-mediated antibacterial immunity: anamnestic production of mediator t cells.	mice that survived an immunizing infection with listeria monocytogenes remained specifically resistant to lethal secondary infection for several months. this acquired, long-lived state of resistance was not dependent on activated macrophages that remained after the primary response. it depended, instead, on an acquired long-lived capacity on the part of immunized mice for generating mediator t cells faster and in larger numbers than normal mice. the number of mediator t cells generated in respon ...	1975	811558
nature of "memory" in t-cell mediated antibacterial immunity: cellular parameters that distinguish between the active immune response and a state of "memory".	immunizing infection in mice with listeria monocytogenes resulted in the generation of two distinct states of immunological reactivity. there was generated (i) a short-lived state of active immunity that functioned to urgently eliminate the infection organism from the tissues and (ii) a long-lives state of increased immunological potential that enabled the host to respond to seconday infection in an accelerated manner. short-lived active immunity was mediated by replicating t cells and expressed ...	1975	811559
dichotomy between macrophage activation and degree of protection against listeria monocytogenes and toxoplasma gondii in mice stimulated with corynebacterium parvum.	in vivo and in vitro experiments were conducted to determine the effect of corynebacterium parvum treatment of mice on resistance of listeria monocytogenes and toxoplasma gondii. intravenous immunization with c. parvum conferred transient protection against intravenous challenge with listeria or an avirulent strain of toxoplasma but did not protect against a virulent strain of toxoplasma. compared with the level of protection conferred by c. parvum, a higher degree of resistance was noted when m ...	1975	811563
[some properties of carrier strains of listeria monocytogenes (author's transl)].	about 60 characteristics have been investigated in 7 hemolyzing and 12 nonhemolyzing strains of l. monocytogenes. from these investigations resulted inter alia that the organism grows well under strictly anaerobic conditions, esculin is split at 45 degrees c,nh3 is produced from peptone, but not from arginin, and h2s can be traced by sufficiently sensitive methods. all strains possess a lipase, muramidase, and deoxyribonuclease, the hemolytic ones only also a lecithinase. besides, the hemolytic ...	1975	811965
nonspecific resistance to listeria monocytogenes in mice infected and elicited with staphylococcus aureus.	normal mice and mice displaying delayed hypersensitivity to staphylococcus aureus were challenged with a lethal dose of listeria monocytogenes. nonspecific antimicrobial activity was assessed by inhibition of bacterial growth in the spleen and by increased survival rates. administration of specific staphylococcal antigen prior to challenge was a prerequisite for the induction of nonspecific resistance. both the time of administering eliciting antigen and the route were important consideration fo ...	1975	811966

macrophage function and host resistance against infection with toxoplasma gondii.	the role of macrophages on the course of an infection with toxoplasma gondii has been examined. stimulation of macrophage function by killed bordetella pertussis cells did not show any beneficial effect as an increased susceptibility became apparent. the functional blockade of macrophages by dextran sulfate or carbon particles did not result in a higher susceptibility of mice to the lethal primary infection with t. gondii. thus in vivo macrophages apparently do not play an essential role as effe ...	1976	974901

[possible relationship between bacterial surface structures, immune-adherence, chemotaxis and phagocytosis (author's transl)].	in the present study we attempted to determine the relationship between bacterial surface structures, immune adherence, chemotaxis and phagocytosis. as shown in table 1 encapsulated bacteria (klebsiella ozanae, k. pneumoniae, pasteurella multocida, streptococcus pneumoniae), mycoplasma pneumoniae and m. fermentans had a much lower immune adherence-activity than non-encapsulated bacteria (bacillus cereus, brucella abortus, erysipelothrix insidiosa, escherichia coli, listeria monocytogenes, pseudo ...	1976	1258564

acute listeria monocytogenes osteomyelitis.	the presentation and management of a case of acute listeria monocytogenes osteomyelitis in a lady with acute lymphoblastic leukaemia are described. the literature on listeria infection is briefly reviewed, and the importance of scrutinizing diphtheroid-like isolates in the laboratory is stressed.	1976	820648
maternal listeria monocytogenes septicemia with sparing of the fetus.	a case of maternal listeria monocytogenes septicemia at 19 week's gestation is presented. successful treatment of the mother with ampicillin resulted in remission of maternal symptoms and subsequent term delivery of an unaffected infant, indicating fetal disease is not an inevitable consequence of maternal listeria sepsis.	1976	821025
[histological study of ceratophyllus consimilis wagn. fleas infected with the causative agent of listeriosis (listeria monocytogenes)].	histological studies have shown that in experimentally infected fleas (c. consimilis) listeria are preserved in the alimentary canal. in infected individuals microbes occur along the whole intestine, from oesophagus to the rectum but most often they are recorded from the mid-gut and proventriculus. listeria are able to penetrate into its muscular tissue and in some cases enter the body cavity of the insect. the finding of listeria in the oesophagus confirms the possibility of the transmission of ...	1976	821031
stimulation of the non-specific resistance by corynebacterium parvum and bacillus calmette guérin.	the effect of pretreatment of intravenously administered killed corynebacterium parvum (cp) and living bcg was studied in various model systems. both vaccines caused an increased resistance to listeria monocytogenes, indicating macrophage activation. only cp exerted a suppressive effect on t-cell-mediated immunological phenomena (skin allograft survival; antibody production to tetanus toxoid; expulsion of adult t. spiralis worms from intestine). results of experiments with congenitally athymic ( ...	1976	821172
[some biochemical studies of listeria monocytogenes strains].	a total of 231 strains of listeria organisms have been isolated during the last 14 years from adult sheep, lambs, fetuses, and ensilaged forage. their differentiation have shown that 67 of them belong to the 1 st serotype, 77 -- to 4 c, and 26 have been determined as strains of the 5th serotype. the biochemical study on 170 of the strains have revealed that: more of them, belong to the 1 st, 4 c, and 5 th serotype break down dextrose, trehalose, levulose, salycin, esculin, ramnose, and glycerin. ...	1976	821209
[detection of h-antibodies in the diagnosis of listeriosis].	the technique of h-antibodies determination in serodiagnosis of listeriosis used at present is capable of detection not only h-antibodies but also flagellar somatic antibodies in the sera. an attempt was made to increase the specificity of h-agglutinins. an experience in the preparation of pure h-antigen is described. however, it is impossible to detect positive h-agglutination either with the aid of a mixture of flagellae and latex or with pure h-antigen. after determination of h-antigen by the ...	1976	821279
effect of pretreatment with bacillus calmette-guerin on the course of a listeria monocytogenes infection in normal and congenitally athymic (nude) mice.	the effect of pretreatment with bcg on the course of a listeria monomcytogenes infection was studied in nu/nu mice and in their heterozygous littermates (+/nu). first, evidence was presented that the nu/nu mice used lacked functional t cells, since bcg treatment resulted only in skin reactivity to tuberculin in +/nu mice and not in nu/nu mice. acquired resistance to listeria (based on lower spleen counts) was only obtained in bcg pretreated +/nu mice. evidence was presented that bcg pretreatment ...	1976	821508
listeria cell wall fraction. characterization of in vitro adjuvant activity.	we have previously described a crude cell wall fraction of listeria monocytogenes (lcwf) which induces resistance to listeria infection in mice, is a murine b-cell mitogen and is an immunological adjuvant. data reported here show that lcwf, which is effective over a wide dose range, exerts its adjuvant action on early events in the induction of an immune response. moreover, lcwf stimulates nonadherent cells to respond to sheep red cells when adherent cells are severely depleted or absent, sugges ...	1976	821854
antimicrobial activity of econazole and miconazole in vitro and in experimental candidiasis and aspergillosis.	the antibacterial and antimycotic activity of econazole base, an imidazole derivative, was examined in vitro and in experimental infections of mice. comparative minimal inhibitory concentration (mic) determinations indicate econazole as well as miconazole to be of moderate activity against gram-positive bacteria (mics: 0.78-25mug/ml) and yeasts (mics: 1.56-25 mug/ml). against filamentous fungi, econazole exhibits better in vitro activity than miconazole and - with the exception of rhizopus oryza ...	1976	817875
bactericidal properties of human cell-free lymph.	the bactericidal properties of human cell-free lymph have been investigated. gram-negative and gram-positive bacteria are susceptible to the killing action of lymph fluid. the colony-forming ability of escherichia coli and bacillus subtilis was reduced by 3 logs after 20 min of incubation with 10% (vol/vol) lymph. salmonella and listeria were less susceptible to killing. the presence of multiple killing factors in lymph showing different specificities for different bacterial cells was demonstrat ...	1976	818015
