| control of corynebacteriophage reproduction by heteroimmune repression. | corynebacteriophages beta and gamma are closely related but heteroimmune; hence, gamma reproduces in c7(beta). a series of gamma mutants, designated gamma-bin (beta-inhibited), has been isolated. they reproduce in only 2 to 14% of infected c7(beta) cells, and, as a result, plaque with an efficiency of 10(-4) to 10(-5) on this strain. the proportion of c7(beta) cells in which gamma-bin phage can replicate is increased to 30 to 80% when immunity is lifted by uv induction of c7(beta) or by heat ind ... | 1978 | 100610 |
| [comparative study of the bactericidal action of the body of ornithodoros papillipes ticks]. | experiments in vivo have shown that the ticks of ornithodoros papillipes inhibit both gram-positive and gram-negative bacteria. on gram-positive microorganisms most sensitive to bactericidal effect of ticks have turned to be micrococci, staphylococci, streptococci and bacteria of diphtheria, of gram-negative ones--bacillus coli. of gram-positive microorganisms less sensitive were listeria, of gram-negative ones--salmonellae, agents of tularemia and pseudotuberculosis. at the infection with bacte ... | 1978 | 100756 |

| [effect of corynebacterium parvum on the immune response in guinea pigs. ii. passive transfer of enhanced anamnestic response and delayed hypersensitivity observed after treatment with corynebacterium parvum]. | after intradermal immunization with a mixture of corynebacterium parvum (c. parvum) and ovalbumin guinea pigs show a markedly increased anamnestic response to an intradermal booster of ovalbumin as compared to controls treated with ovalbumin only. at the same time a reaction of delayed type hypersensitivity is observed in the treated animals, but not in controls. the enhanced anamnestic response as well as the posivitive skin reaction were transferred to strain 2 histocompatible guinea pigs by p ... | 1977 | 148949 |
| an analysis of conditions allowing corynebacterium parvum to cause either augmentation or inhibition of natural killer cell activity against tumor cells in mice. | we have analyzed the impact of in vivo administration of corynebacterium parvum on the mouse immune system against murine tumors, using the natural cytotoxic ability against tumors of normal mouse lymphoid cells as a baseline. a striking difference was found depending on the route of administration. intravenous inoculation of bacteria would result in a significant decrease or sometimes complete abolition of natural cytotoxicity toward tumor cells of the spleen cells of treated mice. on the other ... | 1978 | 149772 |
| ultrastructural basis for the assay of topical acne treatments. transmission and scanning electron microscopy of untreated comedones. | after two decades of using systemic antibiotics as a main treatment for acne, emphasis is again being placed on topical agents. thus, it is highly desirable to have a procedure whereby the activity of the various compounds can be evaluated by direct visualization. scanning electron microscopy combined with transmission electron microscopy provide the tools for such in assay. this study describes the ultrastructure of untreated comedones and provides the baseline or control data necessary for tes ... | 1978 | 151693 |
| [characteristics of nucleoside and pyrimidine base metabolism in corynebacterium glutamicum]. | corynebacterium glutamicum atcc 13032 can utilize uridine as a sole source of carbon for its growth. uridine degradation seems to be catalysed by hydrolase since it does not depend on the presence of phosphorus when the enzyme activity is assayed in vitro. other nucleosides (adenosine, inosine, guanosine, cytidine, thymidine, deoxyuridine, deoxyadenosine, deoxyguanosine) cannot serve as a source of carbon for the growth of the bacterium. the label of thymidine-3h (methyl) is not incorporated int ... | 1978 | 151772 |
| epidemiological features of skin diphtheria infection in rangoon, burma. | a survey for skin diphtheria was carried out on 493 patients with skin lesions who were attending veneral diseases & dermatology clinic in rangoon in 1971. 63.8% of the patients had c. diphtheriae in their skin lesions. all ages and both sexes were equally affected. skin lesions yielding c. diphtheriae on culture were indistinguishable from those associated with other bacteria including ecthyma, pyoderma and secondarily infected with parasitic infections. out of 108 strains tested 18.5% were fou ... | 1978 | 151920 |

| studies on the interference between the allergic reactions caused by different antigen-antibody systems. | interference between two different in vivo antigen-antibody reactions which occurred simultaneously was studied in guinea pigs. animals were presensitized with an aqueous fraction (cp) extracted from cells of corynebacterium equi, strain ko-85. skin reactions of the arthus type elicited by the cp fraction inhibited passive cutaneous anaphylaxis (pca) induced by bovine serum albumin (bsa) and rabbit anti-bsa serum. pca reactions of the cp-sensitized animals were also inhibited upon simultaneous c ... | 1979 | 156162 |
| shunt nephritis: demonstration of diphtheroid antigen in glomeruli. | a 23-year-old girl with a ventriculo-atrial shunt presented with hematuria, proteinuria and severe oedema. diphtheroid organisms were cultured from blood, cerebrospinal fluid and the shung valve. immunoglobulin, complement components and diphtheroid antigenic material were demonstrated in the glomeruli by immunofluorescence microscopy. treatment of her shunt infection by shunt replacement and antibiotic therapy resulted in slow resolution of her nephritis. the slow resolution of her nephritis su ... | 1979 | 160200 |
| comparison of natural killer cells induced by kunjin virus and corynebacterium parvum with those occurring naturally in nude mice. | natural killer (nk) cells are rapidly elicited in the spleen and peritoneal cavity of mice inoculated intravenously or intraperitoneally with live kunjin virus, and more slowly in the peritoneal cavity of mice inoculated intraperitoneally with formalin-inactivated corynebacterium parvum. nk cells induced by either agent display cytotoxicity for a similar spectrum of syngeneic, allogeneic, and xenogeneic cultured cell lines. by contrast, the cells occurring naturally in the spleen of congenitally ... | 1979 | 160889 |

| the action of vibrio cholerae and corynebacterium diphtheriae neuraminidases on the sendai virus receptor of human erythrocytes. | studies of the sendai virus haemagglutinin receptor on the human erythrocyte surface have confirmed that it involves 2 leads to 3 linked sialic acid. because the primary specificity of vibrio cholerae neuraminidase is for this linkage, it is able to compete with the virus for the receptor, to which it adsorbs strongly at low temperatures. corynebacterium diphtheriae neuraminidase, whose principal specificity is for a sialic acid linkage other than 2 leads to 3, does not easily remove sendai viru ... | 1975 | 168311 |
| the mannophosphoinositides of corynebacterium aquaticum. | besides the monomannophosphoinositide previously reported in corynebacterium aquaticum small amounts of other, apparently more glycosylated, mannophosphoinositides have been identified in stationary phase cells. moreover, by labelling cells with [32p]pi, phosphatidylinositol was found, comprising about 1.5% of the stationary-phase phospholipids. 2. pulse-chase experiments performed on cells in the late exponential phase of growth further suggested the sequence phosphatidylinositol leads to monom ... | 1975 | 168883 |
