| characteristics of listeria strains, isolated from micromammalia in bulgaria. | 56 listeria strains isolated from the intestine contents of 13 species of micromammalia in bulgaria were studied. 10 of the strains belong to the serovars 1/2a, 4a, 4b and 5 of listeria monocytogenes and 44 of the strains belong to 10 antigenic variants of listeria innocua. according to their characteristics these strains could hardly cause diseases in humans or domestic animals. two strains have antigenic formulae o-v, vii, xiv and o-v, xiv and cannot be included in the existing classification. ... | 1981 | 6798107 |
| altered resistance to listeria monocytogenes in diabetic mice. | resistance to listeria monocytogenes (l.m.) in diabetic state was studied using streptozotocin (sz)-induced diabetic mice. sz-diabetic mice showed an enhanced resistance to primary listerial infection with a sublethal dose of inoculum, whereas there was no difference between normal and diabetic hosts when challenged with a lethal dose. the growth of l.m. in diabetic mice was inhibited at an early stage of infection. however viable listeria survived in diabetic mice at a later stage, suggesting t ... | 1981 | 6798248 |
| antibacterial peptide from normal rat serum. 1. isolation from whole serum, activity, and microbicidal spectrum. | a procedure is described for purification of the primary bactericidal component of normal rabbit serum active in vitro against bacillus subtilis. a 65 000-fold increase in specific bactericidal activity per milligram of serum protein was obtained, yielding a low molecular weight, heat-stable polypeptide fraction (pc-iii) exhibiting biological activity at protein concentrations below 10 ng/ml. this preparation appeared homogeneous as judged by column chromatography and analytical nadodso4-polyacr ... | 1981 | 6796108 |
| comparative effects of carrageenan on systemic candidiasis and listeriosis in mice. | carrageenan, a toxic substance for the mononuclear phagocyte system (mps), increase drastically the susceptibility of mice against listeria monocytogenes challenge but induces concurrently an increasing resistance against systemic candidiasis and granulocytosis. these results corroborate the minor role played by mps and suggest that polymorphonuclear cells play a major role in non-specific resistance of mice against systemic candidiasis. | 1981 | 6796313 |

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

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

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